Remedying Undue Discrimination Through Open Access Transmission
Service and Standard Electricity Market Design
July 31, 2002.
AGENCY: Federal Energy Regulatory Commission, DOE.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: The Federal Energy Regulatory Commission (Commission) proposes
to amend its regulations under the Federal Power Act (FPA) to modify
the pro forma open access transmission tariff established under the
Commission's Order No. 888 to remedy remaining undue discrimination in
the provision of interstate transmission services and in other industry
practices, and to assure just and reasonable rates within and among
regional power markets. The Commission proposes to require all public
utilities with open access transmission tariffs to file modifications
to their tariffs to reflect non-discriminatory, standardized
transmission service and standardized wholesale electric market design.
DATES: Initial comments are due on October 15, 2002. Comments should
include an executive summary that does not exceed 10 pages.

1. This notice of proposed rulemaking represents the third in a
series of initiatives undertaken by the Commission to harness the
benefits of competitive markets for the nation's electric energy
customers, in order to meet our statutory responsibility to assure
adequate and reliable supplies of electric energy at a just and
reasonable price. In 1996, the Commission issued Order No. 888, which
required, as a remedy for undue discrimination, that all public
utilities provide open access transmission.\1\ In 1999, the Commission
issued Order No. 2000.\2\ The Commission's objective was ``for all
transmission owning entities in the Nation, including non-public
utility entities, to place their transmission facilities under the
control of appropriate regional transmission institutions [RTOs]
in a
timely manner.''\3\

---------------------------------------------------------------------------
2. Order No. 888 and Order No. 2000 set the foundation upon which
to build regional transmission institutions and competitive electricity
markets. However, as events have transpired, there remain significant
impediments to competitive markets and to the infrastructure needed to
meet our electric energy demand. Unduly discriminatory transmission
practices have continued to occur and inconsistent design and
administration of short-term energy markets has resulted in pricing
inefficiencies that can cause rates to be unjust and unreasonable. At
the same time, the nature of the electric industry has changed in a way
that makes the development of competitive wholesale markets all the
more critical. The electric industry has evolved from one characterized
by large, vertically integrated utilities to an industry with
increasing wholesale trade and increasing numbers of independent buyers
and sellers of wholesale power seeking non-discriminatory access to
transmission facilities. Public utilities
[[Page 55455]]
today purchase significantly more wholesale power to meet their load
than in the past. Indeed, from 1989 through 2000, their wholesale
purchases increased from 18 percent of their total available electric
energy to over 37 percent, and this percentage is expected to continue
to grow.\4\
---------------------------------------------------------------------------
\4\ See Section III.C. for a more detailed discussion.
---------------------------------------------------------------------------
3. The Commission's objectives in this third rulemaking initiative,
therefore, are to remedy remaining undue discrimination and establish a
standardized transmission service and wholesale electric market design
that will provide a level playing field for all entities that seek to
participate in wholesale electric markets. The Commission proposes to
provide new choices through a flexible transmission service, and an
open and transparent spot market \5\ design that provides the right
pricing signals for investment in transmission and generation
facilities, as well as investment in demand reduction.
---------------------------------------------------------------------------
\5\ The term ``spot market'' typically refers to a trade that
covers a short period in the very near future. Trading in an
independent transmission system operator (ISO) real-time or day-
ahead market is referred to here as occurring in the spot market. In
the Western price mitigation order, the Commission defined a spot
market trade as any trade lasting 24 hours or less, whether a
bilateral trade or a trade occurring in an organized real-time or
day-ahead market that does not match up particular sellers and
buyers. See San Diego Gas and Electric Company v. Sellers of Energy
and Ancillary Services into Markets Operated by the California
Independent System Operator and the California Power Exchange, 95
FERC [para]
61,418 at 64,525 n.3 (2001). We will adopt this meaning
for this rulemaking.
---------------------------------------------------------------------------
4. When supply and demand do not support fully competitive markets,
market design should provide protection against market power. We seek
in this rulemaking to put in place sufficient regulatory backstops to
protect customers against the exercise of market power when structures
do not support a competitive market. Market monitoring at all times,
and market power mitigation when needed, are critical pieces of this
initiative.
5. A significant impediment to achieving the full benefits of
competition is that there is no single set of rules governing
transmission of electric energy. Not only does the Order No. 888 pro
forma tariff contain provisions that allow different types of customers
to be treated differently, but there also are conflicting state and
Federal rules governing the use of interstate transmission facilities.
This provides opportunities for transmission providers to establish and
apply rules in a way that unduly discriminates against certain classes
of customers, leads to significant transaction costs and threatens
reliability.
6. To remedy undue discrimination, enhance competition, remove
economic inefficiencies and ensure just and reasonable rates, terms and
conditions transmission of electric energy, the Commission proposes to:
Exercise jurisdiction over the transmission component of bundled retail
transactions; modify the existing pro forma transmission tariff to
include a single flexible transmission service (Network Access Service)
that applies consistent transmission rules for all transmission
customers--wholesale, unbundled retail and bundled retail; and provide
a standard market design for wholesale electric markets. While it is
critical that the same non-rate terms and conditions be applied to all
transmission uses, including bundled retail, as soon as possible, we
intend to work closely with our state colleagues with respect to
transition issues involving bundled retail transmission rates
7. The proposed Network Access Service would combine features of
both existing open access transmission services--the flexibility and
resource and load integration of Network Integration Transmission
Service; and the reassignment rights of Point-to-Point Transmission
Service. It would give a customer the right to transmit power between
any points on the transmission system--so long as the transaction is
feasible under a security-constrained dispatch.
8. We expect that most if not all entities will become members of
RTOs and that the new Network Access Service would be provided through
these RTOs. However, this rule may become effective at a time when some
transmission owners and operators have not yet become members of
functioning RTOs. Thus, we propose that all transmission owners and
operators that have not yet joined an RTO must contract with an
independent entity to operate their transmission facilities. This
proposed rule refers to both the RTO and those independent entities as
``Independent Transmission Providers.'' An Independent Transmission
Provider would have no financial interest, either directly or through
an affiliate, as defined in section 2(a)(11) of the Public Utility
Holding Company Act (15 U.S.C. 79b(a)(11), in any market participant
\6\ in the region in which it provides transmission services or in
neighboring regions. We propose that all Independent Transmission
Providers administer the day-ahead and real-time markets. As discussed
infra, we also have identified long-term planning and expansion, system
impact and facilities studies and transmission transfer capability
calculations (including postings on an Open Access Same-time
Information System (OASIS)) as tasks that must be done on a regional
basis. Thus, we propose that all Independent Transmission Providers
perform these tasks.
---------------------------------------------------------------------------
\6\ A market participant means: (i) Any entity that, either
directly or through an affiliate, sells or brokers electric energy,
or provides ancillary services to the [RTO], unless the Commission
finds that the entity does not have economic or commercial interests
that would be significantly affected by the [RTO's]
actions or
decisions; and (ii) Any entity that the Commission finds has
economic or commercial interests that would be significantly
affected by the [RTO's]
actions or decisions. 18 CFR 35.34 (2)
(2002).
---------------------------------------------------------------------------
9. In addition to creating the new Network Access Service, the
revised tariff would include requirements to standardize wholesale
electric market design. The fundamental goal of the Standard Market
Design requirements, in conjunction with the standardized transmission
service, is to create ``seamless'' wholesale power markets that allow
sellers to transact easily across transmission grid boundaries and that
allow customers to receive the benefits of lower-cost and more reliable
electric supply. For example, currently a supplier that seeks to serve
load in a distant state may need to cross several utility systems or
independent system operator systems (ISOs), all of which have different
rules for such things as reserving and scheduling transmission and
scheduling generation. This can either result in an efficient
transaction not occurring at all or it can add significant time and
costs to the transaction. Standard Market Design seeks to eliminate
such impediments.
10. Central to the Standard Market Design concept is its reliance
on bilateral contracts entered into between buyers and sellers. The
resource adequacy requirement strongly encourages such long-term
contracts. The short-term spot markets set out below are intended to
complement bilateral procurement. To handle generation imbalances and
the procurement of ancillary services, the Commission proposes to
require that all Independent Transmission Providers operate markets for
energy and for the procurement of certain ancillary services in
conjunction with markets for transmission service. These markets would
be bid-based, security-constrained spot markets operated in two time
frames: (1) A day ahead of real-time operations, and (2) in real time.
The adoption of a market-based
[[Page 55456]]
locational marginal pricing (LMP) transmission congestion management
system is designed to provide a mechanism for allocating scarce
transmission capacity to those who value it most, while also sending
proper price signals to encourage short-term efficiency in the
provision of transmission service as well as wholesale energy, and to
encourage long-term efficiency in the development of transmission,
generation and demand response infrastructure. We expect that market
participants will strike an appropriate balance between bilateral
contracts and spot market transactions. Efficient spot markets with
appropriate price signals bring bilateral and spot market prices closer
together, helping to assure customers of efficient bilateral markets.
11. Several changes required by Standard Market Design promote
greater customer access to low-cost power. We note that this may raise
concerns that cheap power may leave one region for sale in another,
higher-priced region. This can only happen with generation that is not
already under contract for purchase. Thus, customers in low-cost
regions can ensure that low-cost power ``stays home'' by contracting
for that power. This way, only excess power will leave the region to
serve another market.
12. The Commission proposes a pricing policy and process for
recovering the costs of new transmission investment so as to develop
the infrastructure needed to support competitive markets. The policy
builds on the price signals provided by the proposed spot market
design. However, there are cases where LMP price signals alone will not
encourage all beneficial transmission investments. Therefore, we
propose to require market participants to participate in a regional
process to identify the most efficient and effective means to maintain
reliability and eliminate critical transmission constraints.
13. Even with good market design rules, current supply and demand
conditions make a market monitoring and market power mitigation plan
necessary. The market power mitigation proposed in this rule would rely
on a combination of methods to protect against the exercise of market
power by preventing sellers from withholding economical supplies from
the market, while permitting prices to reflect true scarcity. The
proposed market power mitigation method should be more restrictive at
times or places where the exercise of market power is more likely to
occur than at times or places where the market is sufficiently
competitive.
14. However, because market power mitigation may tend to suppress
scarcity prices that signal the need for investment, a companion
mechanism besides spot prices is needed. The Commission proposes a
resource adequacy requirement to ensure adequate electric generating,
transmission and demand response infrastructure, the level of which is
to be determined on a regional basis. Recognizing that supply planning
and retail customer demand response are the states' responsibility, the
Commission proposes a resource adequacy requirement intended to
complement existing state programs. In particular, the Commission
proposes that an RTO or other regional entity must forecast the
region's future resource needs, facilitate regional determination of an
adequate future level of resources and assess the adequacy of the plans
of load-serving entities \7\ to meet the regional needs. Each load-
serving entity would be required to meet its share of the future
regional need through a combination of generation and demand reduction.
---------------------------------------------------------------------------
\7\ A load-serving entity is an entity, including a municipal
electric system and an electric cooperative, authorized by law,
regulatory authorization or requirement, agreement, or contractual
obligation to supply energy, capacity, and/or ancillary services to
retail customers located within the transmission provider's service
area, including an entity that takes service directly from the
transmission provider to supply its own load in the transmission
provider's service area. See SMD Tariff Sec. 1.
---------------------------------------------------------------------------
15. In summary, in this proceeding, the Commission, pursuant to its
authority under sections 205 and 206 of the Federal Power Act,\8\
proposes to:
---------------------------------------------------------------------------
\8\ 16 U.S.C. 824d and 824e (1994).
---------------------------------------------------------------------------
(1) Establish a single non-discriminatory open access transmission
tariff with a single transmission service (Network Access Service) that
is applicable to all users of the interstate transmission grid:
wholesale and unbundled retail transmission customers, and bundled
retail customers;
(2) Require all public utilities that own, control or operate
interstate transmission facilities to become an Independent
Transmission Provider, turn over their transmission facilities to an
Independent Transmission Provider or contract with an Independent
Transmission Provider to operate their facilities. An Independent
Transmission Provider is any public utility that owns, controls or
operates facilities used for the transmission of electric energy in
interstate commerce, that administers the day-ahead and real-time
energy and ancillary services markets in connection with its provision
of transmission services pursuant to the SMD Tariff, and that is
independent (i.e., has no financial interest, either directly or
through an affiliate, as defined in section 2(a)(11) of the Public
Utility Holding Company Act (15 U.S.C. 79b(a)(11), in any market
participant in the region in which it provides transmission service or
in neighboring regions).
(3) Require that an Independent Transmission Provider provide
transmission services and administer the day-ahead and real-time energy
and ancillary services markets;
(4) Establish an access charge to recover embedded transmission
costs based on a customer's load ratio share of the Independent
Transmission Provider's costs, and would be paid by any customer taking
power off the grid; \9\
---------------------------------------------------------------------------
\9\ As explained in section IV.D.1, current long-term point-to-
point customers that seek to receive Congestion Revenue Rights would
also pay the access charge.
---------------------------------------------------------------------------
(5) Use LMP as the system for transmission congestion management
and provide tradable financial rights--Congestion Revenue Rights \10\
as a means to lock in a fixed price for transmission service;
---------------------------------------------------------------------------
\10\ These rights were called ``Transmission Rights'' in the
Working Paper on Standardized Transmission Service and Wholesale
Electric Market Design, Docket No. RM01-12-000 (Mar. 15, 2002)
(hereinafter Working Paper).
---------------------------------------------------------------------------
(6) Establish a preference for the auction of Congestion Revenue
Rights, but initially allow regional flexibility for a four-year
transition period in determining whether to allocate Congestion Revenue
Rights to existing customers or auction such rights such that revenues
are allocated to existing customers to hold them financially harmless;
(7) Establish open imbalance energy markets to allow all market
participants to buy or sell their imbalances in a fair, efficient and
non-discriminatory market. Imbalance markets would be neutral towards
fuel sources and treat demand resources on an equal footing with
supply;
(8) Permit customers under existing contracts to receive the same
level and quality of service under Standard Market Design that they
receive under their current contracts, to the greatest extent feasible;
(9) Establish procedures to mitigate market power in the day-ahead
and real-time markets required by Standard Market Design and mechanisms
for market monitoring;
(10) Establish procedures to assure, on a long-term regional basis,
that there are adequate transmission, generation and demand-side
resources;
(11) Provide a formal role for state representatives to participate
in the
[[Page 55457]]
decision-making processes of Independent Transmission Providers; and
(12) Clarify the obligation of all users of the transmission system
to comply with all appropriate standards for ensuring system security
and reliability.
16. The Commission's focus is on promoting the development of
competitive wholesale markets and we do not intend to interfere with
the legitimate concerns of state regulatory authorities. It remains
within a state's authority to determine whether or not to provide
retail access. Nevertheless, the reforms proposed in this rulemaking
will benefit customers in states with or without retail access. In
addition, we seek to formally involve state representatives in the
decision-making processes of regional entities. We also recognize the
need to permit parties to continue to rely on existing contracts and
scheduling practices, including those involving hydroelectric power,
and these are fully accommodated under Standard Market Design.
17. The Commission recognizes that differences exist throughout the
regions of the country; however, the Commission's goal is to remedy
undue discrimination by standardizing transmission service and
wholesale electric market design as much as possible. We propose to
allow certain regional variations, as described infra.
18. Finally, the Commission recognizes that implementation of a
revised open access transmission tariff and Standard Market Design on a
nationwide basis may take some time. Thus, the Commission proposes a
phased compliance process. By July 31, 2003, all public utilities that
own, operate or control interstate transmission facilities must file
revised open access transmission tariffs (Interim Tariffs) to become
effective September 30, 2004, that reflect the inclusion of bundled
retail customers as eligible customers. By December 1, 2003, all public
utilities that own, control or operate interstate transmission
facilities must file revised open access transmission tariffs (SMD
Tariffs), to become effective no later than September 30, 2004, or such
other time as directed by the Commission, that reflect all of the
remaining revisions and requirements of the Final Rule in this
proceeding. The Commission and its staff will work with regional
organizations and stakeholders in facilitating full and efficient
compliance with this rule.

II. Background: Order No. 888 and Order No. 2000
A. Order Nos. 888 and 888-A
20. In April 1996, in Order No. 888, the Commission found that
unduly discriminatory and anticompetitive practices existed in the
electric industry, and that public utilities that own, control or
operate interstate transmission facilities had discriminated against
others seeking transmission access. It determined that non-
discriminatory open access transmission services, including access to
transmission information, and stranded cost recovery were the most
critical components of a successful transition to competitive wholesale
electricity markets.\11\ The Commission stated that its goal was to
ensure that customers have the benefits of competitively priced
generation.
---------------------------------------------------------------------------
\11\ See Order No. 888 at 31,652.
---------------------------------------------------------------------------
21. Order No. 888 required all public utilities that own, control
or operate facilities used for transmitting electric energy in
interstate commerce to: (1) File open access non-discriminatory
transmission tariffs containing certain minimum, non-price terms and
conditions, and (2) functionally unbundle wholesale power services from
transmission services.\12\ Functional unbundling requires public
utilities to: (1) Take wholesale transmission services under the same
tariff of general applicability as they offer their customers; (2)
state separate rates for wholesale generation, transmission, and
ancillary services; and (3) rely on the same electronic information
network that their transmission customers rely on to obtain information
about the utilities' transmission systems.\13\ In Order No. 889, issued
concurrent with Order No. 888, the Commission also imposed standards of
conduct governing communications between the utility's transmission and
wholesale power functions, to prevent the utility from giving its power
marketing arm preferential access to transmission information.\14\
Under Order No. 889, all public utilities that own, control or operate
facilities used in the transmission of electric energy in interstate
commerce are required to create or participate in an OASIS that
provides existing and potential transmission customers the same access
to transmission information that will enable them to obtain open access
non-discriminatory transmission service.

22. The Commission declined to require corporate unbundling at the
time of Order No. 888, and stated instead that efforts to remedy undue
discrimination should begin by requiring the less intrusive functional
unbundling approach.\15\ While the Commission in Order No. 888
encouraged the creation of ISOs and set forth eleven principles for
assessing ISO proposals submitted to the Commission, it did not mandate
regional organizations.\16\ The Commission in Order No. 888 stated:
---------------------------------------------------------------------------
\15\ See Order No. 888 at 31,654.
\16\ See id. at 31,730-32.
[W]e see many benefits in ISOs, and encourage utilities to
consider ISOs as a tool to meet the demands of the competitive
marketplace. As a further precaution against discriminatory
behavior, we will continue to monitor electricity markets to ensure
that functional unbundling adequately protects transmission
customers. At the same time, we will analyze all alternative
proposals, including formation of ISOs, and, if it becomes apparent
that functional unbundling is inadequate or unworkable in assuring
non-discriminatory open access transmission, we will reevaluate our
position and decide whether other mechanisms, such as ISOs, should
be required. \17\

Order No. 888-A reaffirmed the findings of Order No. 888. The Court of
Appeals for the District of Columbia Circuit upheld the orders ``in
nearly all respects.'' \18\ The Supreme Court recently affirmed.\19\

---------------------------------------------------------------------------
23. A number of significant developments took place in the electric
utility industry following issuance of Order No. 888. All public
utilities filed non-discriminatory, open access transmission tariffs
stating rates, terms and conditions for comparable
[[Page 55458]]
wholesale transmission service to third-party users of their
transmission systems. With the advent of OASIS systems, improved
information about transmission systems became available to all
participants in the bulk power market at the same time that it was
available to utilities' own wholesale merchant functions and wholesale
marketing affiliates (although further information improvements are
still needed). New generation resources were developed in areas that
had experienced generation shortages.\20\ Regional trading patterns
have expanded. In addition, the Commission granted a large number of
merger applications and applications to charge market-based rates,
effecting structural changes in the industry. The industry thus became
less localized and more regionalized, with a growing need for regional
planning and regulation. And as part of that regionalization, the
Commission also approved voluntary ISOs in five regions of the country-
-New England, New York, PJM,\21\ the Midwest and California (an ISO was
also formed in ERCOT, but it is not under the Commission's full
jurisdiction). These ISOs are the precursors to regional entities
identified as RTOs, in the Commission's Order No. 2000, discussed
below.
---------------------------------------------------------------------------

Commission on the Causes of the Pricing Abnormalities in the Midwest
During June 1998 (1998), available in http://www.ferc.gov/electric/
mastback.pdf.
\21\ The PJM ISO takes its name from the former Pennsylvania,
New Jersey, Maryland Power Pool, which serves New Jersey, Maryland,
Delaware, much of eastern Pennsylvania, the District of Columbia,
and a small area of Virginia.
---------------------------------------------------------------------------
B. Order No. 2000
24. Order No. 2000, issued in December 1999, was the Commission's
second major step toward establishing competitive wholesale power
markets and eliminating residual undue discrimination in interstate
transmission services. It identified two broad categories of
impediments to competitive electricity markets: (1) The engineering and
economic inefficiencies inherent in the current operation and expansion
of the transmission grid, and (2) continuing opportunities for
transmission owners to unduly discriminate in the operation of their
transmission systems so as to favor their own (or their affiliates')
power marketing activities.\22\ Further, evidence indicated that local
management of the transmission grid by many individual vertically
integrated utilities was inadequate to support the efficient, reliable
regionwide operation that was needed for continued development of
competitive markets. The Commission concluded that establishing
independent RTOs would eliminate residual undue discrimination in
transmission, enhance the benefits of competitive electricity markets,
and could: (1) Improve efficiency in transmission grid management; (2)
improve grid reliability; (3) remove remaining opportunities for
discriminatory transmission practices; (4) improve market performance;
and (5) facilitate lighter-handed regulation. The Commission
anticipated that formation of regional transmission grids would result
in a substantial cost savings to the electric utility industry and its
customers.\23\
---------------------------------------------------------------------------
\22\ Order No. 2000 identified four specific areas of concerns:
(1) Calculation and posting of Available Transfer Capability in a
manner favorable to the transmission provider; (2) standards of
conduct violations; (3) line loading relief and congestion
management; and (4) OASIS sites that are difficult to use. See Order
No. 2000 at 31,005 n.69. The order also identified parallel path
flows, planning and investing in new transmission facilities,
pancaking of access charges, the absence of secondary markets in
transmission service and the possible disincentives created by the
level and structure of transmission rates. See id. at 31,014.
\23\ See id. at 30,993.
---------------------------------------------------------------------------
25. Order No. 2000 encouraged all transmission owners to
voluntarily place their transmission facilities in the hands of
appropriate RTOs. The Commission stated that RTOs could include ISOs or
independent for-profit transmission companies (ITCs). However, all RTOs
must meet four minimum characteristics and eight minimum functions that
were identified in Order No. 2000, and also must have an open
architecture framework that would permit an RTO and its members
flexibility to improve their structures over time.\24\
---------------------------------------------------------------------------
\24\ The four RTO characteristics are: (1) Independence; (2)
scope and regional configuration; (3) operational authority; and (4)
short-term reliability. The eight RTO functions are: (1) Tariff
administration and design; (2) congestion management; (3) parallel
path flow; (4) ancillary services; (5) OASIS, Total Transfer
Capability and Available Transfer Capability; (6) market monitoring;
(7) planning and expansion; and (8) interregional coordination. See
Order No. 2000 at 30,993-94.
---------------------------------------------------------------------------
26. Following Order No. 2000, some transmission-owning public
utilities began to file proposals to participate in RTOs. The process
has been slow for several reasons, one of which is stakeholder
uncertainty about what the Commission would require for RTO approval--
not only for the RTO scope and independence characteristics, but also
regarding such RTO functions as congestion management and market-
oriented provision of ancillary services.
27. Order No. 2000 called for RTOs to be in operation across the
nation by December 2001. To date, there is only one RTO fully approved
by the Commission, the Midwest ISO, which began operating in early
2002.\25\ The Midwest ISO is large. It stretches from an eastern
boundary in western Pennsylvania westward to the Rocky Mountains,
northward into Manitoba, Canada and southward to the Texas border.
---------------------------------------------------------------------------
\25\ See Midwest Independent System Operator, Inc., 97 FERC
[para]
61,326 (2001).
---------------------------------------------------------------------------
28. Although progress with Commission-approved RTOs has been slow,
regionalization has also occurred through the ISO formation process
that was encouraged in Order No. 888. The Northeast and California ISOs
are engaged in a process to become Commission-approved RTOs or to join
larger RTOs. In eastern North America, close coordination is developing
between U.S. and Canadian transmission systems and market designs.
29. In addition to the Midwest ISO, the Commission has
provisionally approved other RTOs,\26\ and authorized operation of ITCs
that operate under an RTO umbrella.\27\ The Commission also ordered
Northeastern and Southeastern RTO applicants, including some applicants
whose RTO proposals had been provisionally approved, into mediation
proceedings to facilitate the formation of RTOs in those areas.\28\ The
Commission further noted that a ``west wide RTO, or a seamless
integration of Western RTOs, is the best vehicle for designing and
implementing a long-term regional solution'' to the West's electric
generation supply crisis.\29\

finding some of RTO West's proposed characteristics and functions
compliant with Order No. 2000. See Avista Corporation, et al., 95

proposal for Stage 2 of RTO West's creation on March 28, 2002. The

whether the RTO West proposal fulfills all of the Order No. 2000
characteristics and functions. See Stage 2 Filing and Request for

[[Page 55459]]
30. The following section and related Appendix C discuss specific
features of today's wholesale electricity markets that inhibit the
development of competition and efficient regional markets, and identify
areas in which the Commission must direct reforms to eliminate
remaining undue discrimination and inefficiencies, and ensure just and
reasonable rates.
III. Need for Reform
A. Undue Discrimination and Impediments to Competition Remain
31. Since the issuance of Order Nos. 888 and 2000, it has become
clear that additional, mandatory measures are needed to achieve the
goals of non-discriminatory transmission access and competition in
electricity markets. Vertically integrated transmission owners and
operators continue to use their interstate transmission facilities in
ways that inhibit competition in wholesale power markets as well as
competition in those retail power markets where states have adopted
retail choice. The discriminatory preferences that these transmission
owners and operators give to their own uses of the interstate
transmission grid to serve their retail customers (whether or not they
are in retail choice states) results in discrimination against, and in
costs being borne by, other wholesale and retail customers who also
rely on the interstate transmission facilities to buy power. The
discriminatory preferences also create barriers to new sellers that
could provide lower-cost power. This could result in higher prices to
the native load served by the transmission owner. For example,
transmission-dependent utilities \30\ and other load-serving entities
need the interstate transmission facilities to move power they are
purchasing by contract from distant generators or suppliers, but allege
that despite the requirements of Order No. 888, they are denied
comparable access to the grid. Similarly, new generators wishing to
compete in wholesale markets or for retail customers in retail choice
states tell us that they are denied comparable access to the grid, thus
inhibiting entry of new, lower-cost, efficient and environmentally
superior power suppliers.
---------------------------------------------------------------------------
\30\ A transmission-dependent utility is a utility that does not
own generation and relies on its neighboring utilities to transmit
power to it that it purchases from its suppliers.
---------------------------------------------------------------------------
32. The Commission recently has taken additional steps to address
some of the remaining impediments to non-discriminatory transmission
access and competition in wholesale power markets. For example, the
Commission's recently issued Generator Interconnection proposed rule
seeks to remove one particular type of undue discrimination occurring
in the marketplace--barriers to obtaining interconnections to the
interstate transmission grid--so that new generators can compete with
vertically integrated transmission providers to serve load.\31\
However, this initiative will resolve only one aspect of remaining
discriminatory practices. Other opportunities for vertically integrated
transmission providers to operate in ways that favor their own
generation remain within the construct of the pro forma tariff (e.g.,
preferences for native load and network customers to reserve
transmission capability, differing transmission services that raise
barriers to competition, the lack of inclusion of all services under
the same tariff). As noted in Order No. 2000, ``perceptions of
discrimination are significant impediments to competitive markets.
Efficient and competitive markets will develop only if market
participants have confidence that the system is administered
fairly.''\32\
---------------------------------------------------------------------------
\31\ See Standardization of Generator Interconnection Agreements
and Procedures, 67 FR 22,249 (May 2, 2002), FERC Stats. & Regs.
[para]32,560 at 34,174 (2002) (Notice of Proposed Rulemaking). The
proposed rule defines interconnection study time frames and grants
all generators the opportunity to be treated as competing network
resources in meeting load and load growth. See id. at 34,243-45.
\32\ Order No. 2000 at 31,017. Lack of market confidence may
lead to a reluctance on the part of market participants to share
operational real-time and planning data with transmission providers
because of the suspicion that they could be providing a competitive
advantage to their affiliated power marketers. It may also deter
generation expansion and lead to the perception that the
transmission provider's generation is more reliable, thereby
reducing competition and raising prices for customers. See id.
---------------------------------------------------------------------------
33. Furthermore, it has become apparent that there are also
opportunities to discriminate and to hinder an efficient, competitive
marketplace due to the absence of standardization with respect to
market rules and practices within and between regional markets. So-
called ``seams'' problems (e.g., different rules and different pricing
systems) create transaction costs and artificial barriers to trade.
These problems inhibit the Commission from fulfilling its statutory
responsibility to ensure that customers receive reliable power supplies
at the lowest reasonable costs.\33\
---------------------------------------------------------------------------
\33\ See FPC v. Hope Natural Gas Company, 320 U.S. 591, 610
(1944).
---------------------------------------------------------------------------
34. Finally, innovation that the Commission expected to see with
respect to new service offerings has been sporadic and unsteady.
Innovations in transmission control and pricing (e.g., ISO control of
transmission and LMP for generation and transmission services in the
Northeast, RTO formation in the Midwest), while impressive, have been
slow to take root in other regions of the country. The pro forma tariff
was envisioned as the baseline above which transmission providers were
encouraged to develop competitive and customer-responsive service
offerings. But Florida Power Corporation's network contract demand
service, a hybrid of Network Integration Transmission Service and
Point-to-Point Transmission Service features,\34\ and Duke Energy
Corporation's ``recallable long-term firm'' service \35\ are the only
noteworthy new services accepted by the Commission for use with a
single utility's open access transmission tariff. Other proposed pro
forma tariff revisions amounted to little more than working around the
edges of the existing services and procedures and did not produce more
competitive transmission service that reduces overall electricity
costs.
---------------------------------------------------------------------------
\34\ See Florida Power Corporation, 81 FERC [para]
61,247
(1997).
\35\ See Duke Energy Corporation, 88 FERC [para]
61,184, reh'g
denied, 89 FERC [para]
61,190 (1999).
---------------------------------------------------------------------------
35. Most ISOs recently introduced centralized short-term real-time
hourly markets and day-ahead markets for energy (i.e., spot markets)
where sellers sell into the market and buyers buy from the market
without matching a particular seller with a particular buyer. In such
organized spot markets, there is a single market clearing price
established that is received by all generators who bid into the market
below that price and is paid by all load that bids in above that price.
However, the ability of customers to bid demand reductions into the
spot market in response to supplier prices is still limited and needs
to be improved significantly for short-term markets to operate more
competitively. Further, while there have been benefits of market
development in the Northeast (PJM, New York ISO, ISO-New England),
Texas and California (during the first two years of its restructuring),
the Midwest ISO is still in the formative stages of operation with
respect to markets, and few market benefits have materialized in the
Southeast and West.
B. Specific Instances of Undue Discrimination and Impediments to
Competition
36. The specific reasons for requiring reform are many. Market
participants
[[Page 55460]]
have identified, through formal complaints, hotline calls, public
conferences, and pleadings, the difficulties they have experienced in
gaining equal access to the transmission grid to compete with
vertically integrated utilities to serve load. Much of this problem is
directly attributable to the remaining ability of such vertically
integrated utilities (and the existence of sufficient incentives) to
exercise some degree of transmission market power in order to protect
their own generation market share. Further complicating transmission
access is the fact that not all transmission service is provided under
the rates, terms and conditions of the Commission's pro forma tariff.
Rather, over 60 percent of load has been subject to various state rules
governing the transmission component of bundled retail transactions.
Independent transmission service under a common set of rules would
solve many of these problems.
37. Nevertheless, new problems have been created by some of the
market design experiments. In regions of the country where the
separation of transmission from generation has been addressed through
the creation of ISOs (which, in some instances, have placed nearly all
load under a single tariff), market design flaws create inefficiencies
in the marketplace and opportunities for the exercise of market power.
Conflicting market rules and procedures in neighboring ISOs have
created or perpetuated seams problems that impede the economic flow of
power from one region to another. All of these problems have hindered
the progress towards competitive regional electricity markets. Standard
Market Design is intended to address these problems.
1. Transmission Market Power by Utilities That Are Not Independent
38. By differing means, Order Nos. 888 and 2000 attempt to effect
open access transmission by reducing the ability of transmission owners
that also own generators to act in anticompetitive or unduly
discriminatory ways against other generators. In both orders, the
Commission attempted to move the electric industry into a competitive
wholesale market without mandating corporate restructuring. Through
Order Nos. 888 and 2000, the Commission required open access to public
utility transmission systems, encouraged the formation of ISOs and,
later, RTOs to achieve control of the transmission grid by entities
that are independent from generation marketing or sales. However, only
limited portions of the country have moved beyond the basic
requirements of open access (e.g., through the voluntary divestiture of
generation or establishment of RTOs, ISOs, or ITCs). In the rest of the
country, the remaining corporate ties between generation and
transmission within public utilities have proven problematic for
transmission access. Thus, across most of the nation, barriers to entry
remain for new generators and new load-serving entities.
39. A large portion of this problem is directly attributable to the
continued ability of vertically integrated transmission providers to
exercise some degree of transmission market power to advantage their
own or affiliated generation. The longer the vertically integrated
transmission provider can use access to interconnection or transmission
service to delay or prevent entry of competing generators to its
service territory, the longer it can profit from its own generation
sales with a limited threat of competition. Vertically integrated
transmission providers have found numerous ways to delay or prevent
entry of competitors, some within the existing rules and some by
exceeding reasonable discretion afforded to the transmission provider.
All of these are difficult to monitor or prevent with behavioral
rules.\36\
---------------------------------------------------------------------------
\36\ See Working Paper at 21 (Mar. 15, 2002); see also Comment
of the Staff of the Bureau of Economics and Office of General
Counsel of the Federal Trade Commission, Docket No. RM01-12-000
(July 23, 2002).
---------------------------------------------------------------------------
40. As part of Standard Market Design, we propose that an
Independent Transmission Provider operate all transmission facilities.
The requirement for independent control of the transmission grid,
preferably by an RTO, resolves these types of problems.
a. Load Growth
41. Under the current pro forma tariff, a transmission provider is
required to plan its system to allow customers with existing long-term
contracts to extend, or roll over, those contracts.\37\ However, the
transmission provider has a right to recall that transmission capacity
if it identified in the initial agreement with the customer that it had
projected native load growth that would require that transmission
capacity.\38\ Transmission providers have failed to identify any native
load growth at the time of the initial agreement, and disputes have
arisen with customers claiming they were denied the ability to roll
over their contracts because the transmission provider claimed, well
after the contract was executed, that the transmission capacity at
issue was required to serve native load growth.\39\
---------------------------------------------------------------------------
\37\ See Section 2.2 of the current pro forma tariff.
\38\ See Order No. 888-A at 30,277.
\39\ See Public Service Company of New Mexico v. Arizona Public
Service Co., 99 FERC [para]
61,162 (2002), for a recent example. In
this case, the Commission directed APS to grant PSNM's request to
extend its contract for 60 MW of Point-to-Point Transmission
Service. APS had attempted to deny the rollover request on the basis
that it had verbally informed PSNM that capacity would not be
available due to APS's future native load growth. The Commission
restated the principle that a transmission provider can deny a
customer the ability to roll over its long-term firm service
contract only if the transmission provider includes in the service
agreement a specific limitation based on reasonably forecasted
native load needs that will use the transmission capacity provided
under the contract at the end of the contract term.
---------------------------------------------------------------------------
42. In Standard Market Design, we propose to eliminate the
preference for future native load growth. Instead, since Congestion
Revenue Rights will be used to assure price certainty, Congestion
Revenue Rights will be apportioned based on historical use or by an
auction, neither of which grants preference for future load growth by a
particular supplier; this approach resolves these concerns.
b. Delays in Responding to Requests for Service
43. Another type of anticompetitive behavior centers on a
vertically integrated transmission provider delaying the processing of
a competitor's request for new transmission service or interconnection
(including the related system impact or facilities studies).
Transmission providers have done so by failing to follow time lines or
expansively interpreting the tariff procedures. These delays may be
enough to cause the competing generator to lose the sale, particularly
if the potential customer is concerned that it may lose service
completely if it does not stay with the transmission provider.\40\
---------------------------------------------------------------------------
\40\ See Kinder Morgan Power Co. v. Southern Company Services,
Inc., 97 FERC [para]
61,240 (2001), reh'g denied, 98 FERC [para]
61,044 (2002) (finding Southern's interconnection procedures delayed
and discriminated against customer's ability to develop new
projects).
---------------------------------------------------------------------------
44. Under Standard Market Design, these types of delays are
resolved through the requirement for an independent entity, preferably
an RTO, to perform studies and calculate available transfer capability
(ATC),\41\ since an independent entity would have no incentive to favor
one customer over another.
---------------------------------------------------------------------------
\41\ The Commission used the term ``Available Transmission
Capability'' in Order No. 888 to describe the amount of additional
capability available in the transmission network to accommodate
additional transmission services. To be consistent with the term
generally accepted throughout the industry, ``Available Transfer
Capability'' will be used.
---------------------------------------------------------------------------
[[Page 55461]]
c. Scheduling Advantages
45. A vertically integrated transmission provider has a structural
advantage over many competitors to make economy sales or to serve its
own load, primarily because it has a large portfolio of both generators
and loads. A competitor with access only to generation outside of the
control area and no native load has to identify the delivery point of
its power before being able to secure transmission service. But a
vertically integrated transmission provider does not have to identify a
specific location on the grid to serve its load because its load is
dispersed across its entire system. A vertically integrated
transmission provider also does not have to identify a single
generation location, but can run a combination of its own generators or
purchase from lower cost-suppliers inside or outside of its system. It
can schedule purchased power to one of its own loads (in place of power
from one of its own generators) in order to secure transmission service
for the purchase. Later, it can find a buyer for the power and schedule
transmission service from one of its internal generators to the load.
This often is enough of a scheduling advantage over a competing
supplier to ensure that the transmission provider (or its affiliated
power marketer) gets the sale.
46. While it is true that all network customers have these same
rights and abilities, in many areas of the country the only customer
using network service is the vertically integrated transmission
provider. Moreover, the vertically integrated transmission provider's
size of resources and loads is usually much greater than any other
network customer, giving it that much more of an advantage in
flexibility. In addition, the vertically integrated transmission
provider may have an advantage through access to better or more
transmission and other related information.
47. Under Standard Market Design, all transmission service will be
provided under a new Network Access Service. Having one service for all
customers will eliminate scheduling advantages of competing suppliers.
d. Imbalance Resolution
48. Customers have also alleged that vertically integrated
transmission providers have an advantage over competitors in the
resolution of energy imbalances. Transmission providers with generation
and load of their own can resolve their own energy imbalances through
in-kind energy exchanges with neighboring systems. In contrast, other
customers of the transmission provider face higher costs if they take
service from other suppliers that could balance against each other.
This difference gives the transmission provider a competitive advantage
over other sellers of power.
49. Under Standard Market Design, all suppliers and loads on a
system will resolve imbalances through the same energy imbalance
procedures. This will remove any competitive advantage the transmission
owner with its own generation and load may have over competing power
suppliers.
e. Available Transfer Capability and Affiliates
50. Another source of discrimination is the calculation of
Available Transfer Capability. A transmission provider that is not
independent calculates its Available Transfer Capability, using its own
proprietary data and its own equations. This discretion gives it the
ability and the opportunity to discriminate in its own favor against
entities that rely upon the OASIS for Available Transfer Capability
information. In several cases, the Commission has found that utilities'
OASIS postings reflect an inaccurate Available Transfer Capability.
Indeed, in response to ``serious concerns about the integrity of the
postings of ATC'' on the OASIS systems of two transmission providers,
the Commission required the transmission providers to employ an
independent third party to administer their OASIS systems.\42\

et al. See also American Electric Power Company, Inc. and Central
and South West Corporation, 90 FERC [para]

(requiring AEP to turn over its OASIS and ATC calculation functions
to an independent entity as a condition of the applicants' merger).
See also Appendix C for other examples.
---------------------------------------------------------------------------
51. Under Standard Market Design, an independent entity will
calculate Available Transfer Capability and schedule transmission
service. This will eliminate this potential for undue discrimination.
f. OASIS Postings
52. Manipulation or violation of OASIS posting requirements and the
Commission's standards of conduct is another way vertically integrated
transmission providers that control their own OASIS sites are able to
engage in undue discrimination. This can occur through prohibited off-
OASIS communications between the transmission provider and its
affiliated market participant, e.g., informing only the affiliate about
Available Transfer Capability that will soon become available and
posted on the OASIS so that the affiliate will be first in line to
claim the capability.\43\ Such abuses reinforce our belief that, in the
absence of an independent entity calculating Available Transfer
Capability and operating a transmission provider's OASIS, ``a
transmission provider's self-monitoring of its standards of conduct is
not sufficient, and that it is essential for interested parties to be
able to participate in this process'' of reviewing communications
between market participants.\44\ Further, even with the best of
intentions, it is not possible for a single transmission provider in a
region to calculate Available Transfer Capability on its system alone
without accounting for the transactions over all the other systems in
its region and neighboring regions.
---------------------------------------------------------------------------
\43\ See Aquila Energy Marketing Corporation v. Niagara Mohawk
Power Corporation, 87 FERC [para]
61,328 (1999) (finding that off-
OASIS communication between utility and its marketing affiliate led
to preferential treatment of the affiliate); The Washington Water
Power Company, 83 FERC [para]
61,097 (1998) (finding favorable
treatment of affiliate and expressing concern that this treatment
may have been the result of prohibited off-OASIS communication).

Corporation, 87 FERC [para]
61,238 at 62,279 (1999).
---------------------------------------------------------------------------
53. Similarly, control over the design, function and maintenance of
OASIS systems may also present opportunities for discrimination. The
Commission has been concerned for some time that transmission providers
have the ability to impede competition by making their OASIS sites
difficult to use, limiting users' access to OASIS and limiting access
to information about transmission curtailments and interruptions that
would allow the Commission to identify instances of undue
discrimination.\45\
---------------------------------------------------------------------------
\45\ See Regional Transmission Organizations, FERC Stats. &
Regs. [para]
32,541 at 33,713 (describing market participants'
perceptions that transmission providers may use OASIS to
discriminate among market participants); Open Access Same-Time
Information System, 64 FR 34,117 (June 25, 1999), FERC Stats. &
Regs. [para]
31,075 (1999) (articulating changes to Commission
regulations that would make available more information about
transmission curtailments and interruptions and limit OASIS hosts'
ability to disconnect users).
---------------------------------------------------------------------------
54. Under Standard Market Design, an independent entity will
operate an OASIS on a regional basis, and thus will remove any
advantages one seller may have over another and improve the accuracy of
regional Available Transfer Capability postings on the OASIS.
g. Capacity Benefit Margin Manipulation
55. The Commission has found instances of transmission providers
taking advantage of their ability to reserve interface capability to
serve their
[[Page 55462]]
own load while limiting the ability of competing suppliers to access
customers on its system. For instance, transmission providers have
reserved excessive amounts of capacity benefit margin (CBM) to serve
their own load,\46\ and violated the pro forma tariff by reserving
large amounts (e.g., 2,000 MW) of transfer capability at multiple
interfaces, under the label of ``firm import for native load,'' without
designating resources or loads associated with the reservations as
other transmission customers are required to do.\47\ Import capability
reserved by the transmission provider blocks a competing supplier from
securing firm service across the interface, limiting that supplier's
ability to compete to serve load on the system, or on neighboring
systems. A related issue is whether those who set aside transmission
for CBM are reserving it and paying for it under the terms of the pro
forma tariff. When transfer capability for CBM is set aside for the use
of one market participant, its cost is not necessarily allocated to
that market participant alone. Because transmission facility embedded
costs are allocated to transmission customers on the basis of use--
capacity reservation for Point-to-Point Transmission Service customers
and load ratio share (which does not include the transmission
capability set-aside of CBM) for Network Integration Transmission
Service customers--all customers may unfairly subsidize the cost of the
CBM capability.
---------------------------------------------------------------------------
\46\ See Delegated Letter in Docket No. ER98-4410-000 (Feb. 8,
1999); Entergy Services, Inc., 87 FERC [para]

(directing Entergy, which had reserved 2900 MW, to recompute ATC).
\47\ See Aquila Power Corporation v. Entergy Services, Inc., 90

appeal docketed, No. 00-1417 (D.C. Cir. Sept. 22, 2000). The
Commission did not order a remedy in the complaint docket since the
compliance filing in Docket No. ER98-4410 to remedy the excessive
native load reservations would also provide a remedy for the
improper native load reservations at the interfaces. See id. at
61,860.
---------------------------------------------------------------------------
56. Under Standard Market Design, entities that want to reserve
transfer capability must pay for that capability to reach generation
reserves across an interface. Thus, the preferential treatment would be
eliminated.
h. Discretionary Use of Transmission Loading Relief
57. The opportunity for anticompetitive behavior arises when
transmission providers have discretion to dispatch their own generation
to serve their own load in a way that requires transmission service
curtailments through the use of transmission loading relief (TLR)
procedures.
58. There has been a sharp increase in the number of TLRs used in
some regions, suggesting that transmission operators rely upon them to
do more than simply relieve emergency transmission overloads.\48\ There
are unmistakable financial incentives to rely on TLRs in forward
transmission planning:
---------------------------------------------------------------------------
\48\ In the Southeast, the incidence of TLRs increased 354
percent from the summer of 1999 to the summer of 2000. See Staff
Report to the Federal Energy Regulatory Commission on the Bulk Power
Markets in the United States (Nov. 1, 2000), available in <http://
www.ferc.gov/electric/bulkpower/southeast.pdf, at 3-38.
In the Midwest, the incidence increased 472 percent over the same
time period. See Staff Report to the Federal Energy Regulatory
Commission on the Bulk Power Markets in the United States (Nov. 1,
2000), available in <http://www.ferc.gov/electric/bulkpower/
midwest.pdf, at 2-32. The lack of a centralized market,
particularly in the Southeast, has limited market liquidity and,
thus, increased the likelihood of TLRs.
The increased incidence of TLRs may suggest that some
transmission capacity is being oversold. Market participants have
attributed a tendency to implement a greater number of TLRs to the
commercial reality that transmission providers do not have to refund
transmission reservation fees for service curtailed because a TLR is
called.\49\

the Bulk Power Markets in the United States (Nov. 1, 2000),

southeast.pdf at 3-39.
59. When a vertically integrated transmission provider injects
power from its own generation onto its own power lines to meet the
constantly shifting demands of the load on its system, it has both the
opportunity and the incentive to manipulate the transmission system for
its own benefit. It can either dispatch generators to create a
transmission constraint that prevents a competitor from making a sale
that the transmission provider would also like to make, or it can
capitalize on legitimate constraints into a load pocket to curtail a
competitor's transmission transaction and serve the customer with its
own generation instead. The key here is that none of the transmission
provider's actions require direct communication with its merchant
function or marketing affiliate. A simplified hypothetical example of
such anti-competitive behavior is set forth in Appendix C.
60. Several aspects of our proposed remedy address this concern,
including the use of LMP to manage congestion and the requirement that
transmission facilities be operated by an Independent Transmission
Provider.
2. Lack of Common Rules Governing Transmission
61. Some of the difficulties that come from having different rules
as power moves across the grid are discussed later in the Seams
Problems Section III.B.4), where a ``seam'' is a dividing line between
different sets of grid rules.
62. Having two or more different sets of rules governing the
operation of a transmission system makes it difficult--if not at times
impossible--for that system to support an efficient regional electric
power market. If the interstate transmission system is to provide fair
and efficient movement of power on behalf of all users of the system,
the same general rules must govern such matters as who gets service,
who has the right to transmission service when not all service requests
can be accepted, how the transmission facility costs are allocated
among transmission customers, who gets its transmission curtailed and
by how much when a transmission outage prevents all the planned
services from being accommodated, who plans the additions to the grid
and who pays for these additions.
63. Today there are not only different rules in different public
utility systems, but there may be more than one set of rules for
transmission owned by a single utility. This is because there are
different rules for two types of wholesale transmission service, and
the rules for bundled retail transmission service may differ from the
rules for wholesale and unbundled retail transmission services.
64. The Commission established an open access transmission tariff
under Order No. 888 that provides for two distinct types of wholesale
transmission services--Network Integration Transmission Service and
Point-to-Point Transmission Service. Network Integration Transmission
Service was designed primarily to meet the needs of the transmission
customer that wants to integrate many generators and many loads at
diverse locations on the public utility's grid; it was intended to be
comparable to the service that the public utility provided to its own
bundled retail customers. Point-to-Point Transmission Service, as the
name implies, was designed primarily for the customer that wants to
move power from one discrete location to another.
65. At the time Order No. 888 issued, the Commission recognized the
potential for problems with having two wholesale services that could
not be truly equal, especially the problem of dealing with claims of
undue discrimination between the services.
[[Page 55463]]
Consequently, along with the issuance of Order No. 888 the Commission
proposed a rule to create a new tariff, called the Capacity Reservation
Tariff.\50\ It was intended to remedy the anticipated problems by
establishing a new tariff that would replace the two wholesale services
with one. The Commission received many comments on the proposed rule
and held a technical conference with representatives of diverse
stakeholders.\51\
---------------------------------------------------------------------------
\50\ See Capacity Reservation Open-Access Transmission Tariffs,
61 FR 21,847 (May 10, 1996), FERC Stats. and Regs. [para]
32,519
(1996) (Notice of Proposed Rulemaking).
\51\ See Capacity Reservation Open-Access Transmission Tariffs,
76 FERC [para]
61,065 (1996) (notice extending deadline for filing
written comments and convening technical conference).
---------------------------------------------------------------------------
66. Some parties expressed concern about moving quickly to a single
service based on the Capacity Reservation Tariff model, while other
parties asserted that, although a single tariff reducing the two
services to one was a good policy, there were problems with the
particular Capacity Reservation Tariff that was proposed. They
recommended that the Commission delay acting on the proposed rule until
it learned the best form of single service tariff through industry
experience with open access. This is the approach that the Commission
in effect followed. Since the two Order No. 888 services were adopted,
however, there have been allegations of undue discrimination between
customers of the two services as discussed later in this section.
67. There are also different rules for bundled retail transmission
service and for wholesale and unbundled retail transmission services.
States have historically established the rules for the transmission
component of bundled retail transactions, while the Commission has
established the rules for wholesale and unbundled retail transmission
services.
68. Despite the requirement in Order No. 888 that no transmission
customer may have any undue advantage over another, there remain real
or perceived advantages for the customers of vertically integrated
transmission owners. In many cases, the perceived advantage is one of
Network Integration Transmission Service over Point-to-Point
Transmission Service, where Network Integration Transmission Service is
available to both bundled retail transmission customers and wholesale
Network Integration Transmission Service customers, while Point-to-
Point Transmission Service is taken primarily for wholesale
transmission by independent power producers and marketers.
69. Four prominent examples highlight the alleged advantages that a
public utility's bundled retail customers have over wholesale and
unbundled retail customers. First, certain reliability practices
related to keeping the transmission system balanced may allow a public
utility that is responsible for keeping generation and load in balance
to obtain lower costs for its own power customers. Second, a
transmission-owning public utility may have more de facto flexibility
to designate transmission receipt and delivery points than other
transmission customers, if that public utility also provides power to
customers on its transmission system. Third, the bundled retail
customers of a transmission owner may have certain transmission
reservation and pricing advantages regarding transmission transfer
capability set aside for reliability. Fourth, state transmission
curtailment rules that favor a public utility's bundled retail
customers may conflict with the Commission's transmission curtailment
rules, resulting in a transmission preference to customers in one state
over customers served in other states.\52\ The first three of these
were summarized above, and a detailed discussion with examples is set
forth in Appendix C.
---------------------------------------------------------------------------
\52\ We emphasize that transmission curtailment does not
necessarily mean a power outage.
---------------------------------------------------------------------------
70. The requirement for all services on the transmission grid to be
taken under a common set of rates, terms and conditions will resolve
these concerns.
3. Congestion Management
71. Due to new transmission usage patterns and the lack of
transmission infrastructure improvements, congestion has increased.
However, economically sound congestion management plans do not exist in
most parts of the country, and transmission customers have been exposed
to transmission service interruptions and increasing generation costs
due to the risk of interruption. The operating rules that do exist were
not designed as a congestion management tool for allocating scarce
transmission capacity, but were designed to keep facilities from
overloading in an emergency, such as when a transmission facility
unexpectedly goes out of service.
72. Currently, under the existing pro forma tariff, congestion is
managed primarily through a system of physical reservation of capacity,
based on each individual transmission provider's calculation of the
Available Transfer Capability of its grid, a calculation often made
without knowledge of the power flows on its grid that result from
transactions scheduled over other grids in its region. Under the
current pro forma tariff, customers reserve capacity on either a firm
or non-firm basis, based on the assumed contract path that the
transaction will use. Once the customer has reserved capacity on a firm
basis, it is supposed to receive certainty both that power will be
delivered and the price that the customer will be charged for
transmission. If the customer has non-firm capacity, it has no
certainty that capacity will be available to deliver power, but does
know that there will be no congestion charge if the delivery does
occur.
73. The existing pro forma tariff also provides that the redispatch
of a transmission provider's generating units to relieve congestion is
required only if it can be achieved while maintaining reliable
operation of the transmission system in accordance with prudent utility
practice. The recovery of the higher generation costs resulting from
such generator redispatch, which are a subset of opportunity costs,
requires that (1) a formal generator redispatch protocol be developed
and made available to all transmission customers and (2) all
information to calculate redispatch costs be made available to the
customer for audit. If a transmission provider collects revenues to
cover the redispatch costs from a specific transmission customer, it
must credit these revenues to the cost of fuel and purchased power
expense included in its wholesale fuel adjustment clause. Various
tariff provisions specify how redispatch is to be implemented. For
instance, Sections 33.2 and 33.3 of the existing pro forma tariff
provide that the redispatch of all network resources and the
transmission provider's own resources, on a least-cost basis without
regard to ownership, is to be performed only to maintain system
reliability, not for economic reasons. Under those circumstances, the
redispatch costs would be shared among the network customers and the
transmission provider on a load ratio basis. Sections 13.5 and 27 of
the existing pro forma tariff permit the transmission provider to
provide the requested transmission service and relieve a system
constraint by redispatching the transmission provider's resources: (1)
If this costs less than constructing network upgrades; and (2) if,
under Section 13.5, the transmission customer agrees to compensate the
transmission provider for any such redispatch costs on an incremental
basis as specified in the
[[Page 55464]]
customer's service agreement prior to the commencement of service.
74. Although the existing pro forma tariff allows the recovery of
generating unit redispatch costs, the Commission generally has not
accepted proposals submitted by single-utility transmission providers
to recover such costs. For instance, the Commission rejected Bangor
Hydro-Electric Company's (Bangor Hydro) proposed formula to recover
opportunity costs for lack of supporting data showing that its
opportunity cost pricing would be consistent with the principle of
comparability and because the formula lacked sufficient detail to
operate as a rate formula itself.\53\ The Commission directed Bangor
Hydro to submit a separate section 205 filing with revised opportunity
cost pricing before implementing such pricing. The Commission also
rejected a proposal by the operating companies of Central and South
West Corporation (CSW) regarding redispatch costs because they did not
provide sufficient specificity to enable a customer to calculate or
verify redispatch costs and because the formula lacked sufficient
detail to operate as a formula rate.\54\ The Commission also directed
CSW to submit a separate filing under section 205 before implementing
such pricing.

\53\ See Allegheny Power System, Inc., et al., 80 FERC [para]
61,143 (1997).
\54\ Central Power and Light Company, 81 FERC [para]
61,311
(1997).
---------------------------------------------------------------------------
75. Because it is difficult for a single-utility transmission
provider to develop a formula that specifies the costs of redispatch
and protects transmission customers' interests, generation redispatch
has not been used as extensively as it could be used to relieve
congestion. A transmission provider will not redispatch generating
units if it cannot collect its higher generation costs, and less
transmission transfer capability will be available to the energy
market.
76. In 1998, the Commission called on public utilities to work with
the North American Electric Reliability Council (NERC) to develop a
congestion management system based on redispatch.\55\ NERC responded
with its pilot Market Redispatch program that relied on counterflow
transactions, i.e., power transfers against the prevailing flows on the
constraint, to relieve the congestion.\56\ Although the program has
been in place for several years, it has been implemented only
infrequently because of the difficulty in establishing counterflow
transactions and the limited availability of data to the transmitting
customer.\57\
---------------------------------------------------------------------------
\55\ The NERC rules for protecting the system were designed to
adapt the Commission's Order No. 888 individual utility transmission
curtailment requirements to multi-system transactions and parallel
flows. See North American Electric Reliability Council, 85 FERC
[para]
61,353, 62,363-64 (1998).
\56\ See North American Electric Reliability Council, et al., 87
FERC [para]
61,160 (1999).
\57\ NERC identified several problems with the program in a
January 31, 2002 submittal to the Commission: (1) The Market
Redispatch customer cannot easily anticipate and specify in advance
which facilities will overload and require transmission curtailment;
(2) the Market Redispatch transaction must provide a counterflow for
the entire protected transaction even though the required
transmisssion curtailment may be only a portion of the original
protected transaction; and (3) the Market Redispatch customer cannot
easily discover the availability of generator pairs for counterflow
transactions. See Report on Market Redispatch Pilot Program by NERC
Market Interface Committee and Motion to Continue Market Redispatch
Program, Docket No. ER02-933-000, at 3 (Jan. 31, 2002).
---------------------------------------------------------------------------
77. In 1998, Commonwealth Edison Company (ComEd) proposed a similar
voluntary redispatch program, which predated NERC's Market Redispatch
Program.\58\ In November 1998, ComEd submitted the first of two interim
reports to the Commission summarizing its experience with the
program.\59\ It determined that a single utility cannot effectively
offer redispatch over other systems, especially where other generation
owners do not participate.
---------------------------------------------------------------------------
\58\ See Commonwealth Edison Company, et al., 83 FERC [para]
61,145 (1998).
\59\ Interim Report on Non-Firm Redispatch, Docket No. ER98-
2279-000 (Dec. 17, 1998).
---------------------------------------------------------------------------
78. The overall result of the Order No. 888 congestion management
system is that the transmission system is not utilized in the most
efficient manner. Customers can be denied access to lower-cost supplies
that could be made available if the congestion management and pricing
system had an efficient and fair method of recovering the cost of
generator redispatch.
79. Managing congestion using an LMP system, coupled with a single
transmission service that relies on price (rather than first-come,
first-served) to allocate limited transmission capacity, will resolve
these problems.
4. Seams Problems
80. A lack of common transmission rules inhibits competition in
power markets not only when there are different rules for different
customers under one public utility's tariff or one RTO's tariff, but
also when there are different rules from one public utility to the
next, or from one RTO to the next. The term ``seam'' has come into
common use in the electric power industry over the last several years
to refer to a boundary between areas with different transmission or
other market rules. Market participants assert that it can be difficult
to move power ``across a seam'' from one area to another.
81. Seams issues include differences in transmission rules as well
as differences in power market rules. They include such diverse matters
as different operating rules (e.g., rules for recalling firm
transmission capacity; coordination of generation and transmission
maintenance schedules; how parallel path flows are determined to affect
other regions); different market rules (e.g., bidding rules; market
product definitions); different market designs (e.g., congestion
management procedures; demand response rules; market price intervention
practices); different business practices (e.g., scheduling practices;
reservation practices; OASIS designs; processes to verify transactions
between ISOs and market participants; transmission and generation
outage information dissemination, compensation, and coordination rules;
generation interconnection practices; liability provisions); and
different electronic and telephonic communications protocols.
82. Market participants have called for a ``seamless market,'' by
which they mean a market whose operation is not encumbered by
differences in rules at public utility or RTO boundaries. To achieve a
seamless market, some assert that rules may differ but only in ways
that the differences are invisible to power sellers and buyers. Others
assert that such management of differences rarely works in practice and
that the rules must be the same everywhere to achieve a seamless
market.
83. The Commission has long recognized the need for more
coordination and uniformity throughout a region in transmission
matters. Our Regional Transmission Group Policy Statement of 1993 \60\
encouraged public utilities to develop a common set of rules for
regional expansion planning, and our Transmission Pricing Policy
Statement of 1994 \61\ encouraged the development of a common pricing
policy for a region that would internalize and rationalize the pricing
of parallel path flows. As explained above, Order Nos. 888 and 2000
recognized the need to bring the various public utility
[[Page 55465]]
transmission systems in a region under a common set of transmission
rules. Order No. 888 not only applied a common set of open access
transmission rules to public utility transmission systems, but included
a reciprocity provision that conditioned a non-public utility's use of
a public utility's open access transmission tariff on the non-public
utility's agreement to provide comparable transmission service to the
public utility. Indeed, Order No. 888 also encouraged the formation of
ISOs not only to bring all the transmission systems in a region under
common rules, but also under unified operation. Many parties in Canada
have stressed the necessity of having a common set of rules for
reliability and trading protocols for cross-border transmission
facilities.\62\ Order No. 2000 built on this theme by strongly
encouraging the formation of RTOs to bring all facilities in a region
under a common set of transmission rules. However, RTOs have not
developed at the pace anticipated when Order No. 2000 was issued and
seams problems continue to exist. In June 2001, the Commission held a
technical conference on seams issues.\63\ Participants to the seams
conference explained that resolution of seams issues is critical for
making the inter-RTO transmission systems and power markets work.

Canadian electricity companies are linked to their counterparts

interconnectedness itself enhances our respective energy security,
but it also places an onus on our countries to act together to
manage the grid. Nowhere is that more important than in the area of
electricity reliability. * * * Because uniformity in reliability
standards is required to enable effective electricity trade,
variations in standards would impede electricity trade and balkanize
markets.
\63\ Conference on RTO Interregional Coordination, Docket No.
PL01-5-000, June 19, 2001. Called by many the ``FERC Seams
Conference,'' this technical conference on the RTO interregional
coordination requirements of Order No. 2000 helped the Commission
learn about seams issues and about how uniform standards for some
rules could benefit power markets.
---------------------------------------------------------------------------
84. We set forth in Appendix C a number of examples of differences
in rules that can create seams problems, and a discussion of efforts at
the Commission or within the industry to address seams problems.
85. The requirement under Standard Market Design for a single
tariff and a single market design operating with the same set of rules
throughout the entire interconnection resolves the seams problems
discussed above.
5. Market Design Flaws
86. Poorly designed market rules, or market rules with unforeseen
or unintended consequences, can have a debilitating effect on markets,
market pricing and overall confidence in the markets of the market
participants. Moreover, differences in market designs in neighboring
regions can also lead to problems such as the exercise of market power
through the exploitation of the differences.
87. Wholesale electricity markets are complex, with multiple
products traded at multiple locations on different time-frames, while
subject to the unique physical characteristics of electricity (e.g.,
non-storable, need for system stability and balancing, physics of power
flows). Market rules have been affected by the variation in generation
mix, the transmission network layout and the local and regional
regulatory history in different regions of the country. For example,
the initial California markets had a design quite different from the
designs of the markets in the Northeast region (PJM, New York and New
England).
88. In the regions where voluntary, organized ISO markets for
energy, transmission and ancillary services have been established under
the existing tariff, problems due to the design choices have been
characterized as ``market design flaws.'' A market design flaw is a
market rule--including product specification, bid format, auction rules
and pricing rules--that allows distortions in the market prices or
availability of a product or service, whether energy, ancillary
services, transmission service or installed capacity. In the years
since the ISO markets have been operating, dozens of market design
flaws have been identified, ranging from minor problems that cause
temporary inconveniences to major problems that require markets to be
re-designed. No region has been exempt from market design flaws of one
type or another. We set forth in Appendix C examples of specific design
flaws.
89. These problems have resulted in markets that are inefficient
and do not produce the lowest reasonable prices for electric power.
These problems cannot be resolved on a case-by-case basis because that
will maintain and exacerbate the problems due to local differences in
rules. Only standardization of electricity market design will solve
these problems. In the parts of the country in which markets are most
mature, including the Northeast, Midwest and California, there is broad
consensus on the principal elements of market design and business
practices. A standard market design rule will help advance this process
and extend it to other regions. Our goal is to use the Standard Market
Design rulemaking to address and remedy many of the market design flaws
identified to date and to raise the quality of all electric markets
simultaneously.
90. Market rules will need to be flexible and have the ability to
evolve over time. However, consistent rules across the entire
interconnection based on best practices, coupled with sound market
monitoring to promptly identify and correct any design flaws will
provide the necessary foundation for future market innovation and
improvement.
C. Reform Essential Given the Changed Nature of the Electric Industry
91. The need to address the instances of discrimination described
above is all the more critical given the changing nature of the
electric industry. The United States electric power industry is in the
middle of a transition from a predominantly monopoly industry to a
predominantly competitive industry. The fundamental economic driver of
change has been, and continues to be, the reduction of economies of
scale in new generation construction, combined with environmental
restrictions that encourage gas-fired units. This is due in large part
to the introduction during the 1980s of highly efficient gas turbines
and combined cycle generators that produce much more electricity from a
given amount of gas. A relatively small gas-fired generator can compete
effectively with power from a large central generating station.
Additionally, small distributed generation is becoming economic, and
some renewable energy resources, especially wind power generation, are
also on the verge of becoming competitive.\64\ In the right locations,
wind generating units can compete with the much larger coal, nuclear
and hydroelectric units.\65\

Off? A Survey of Projects and Economics, Pub. Util. Fort., Aug. 2001

---------------------------------------------------------------------------
92. Because of these fundamental changes in industry technology,
small producers of electricity can compete with large producers, and
both the smaller utilities and the retail customers of a number of
utilities have demanded access to competing power suppliers in hopes of
lowering their electric bills,
[[Page 55466]]
improving service and harnessing new technologies. The pressures for
retail access have been greater in regions with higher rates, which are
typically regions with few low-cost natural resources for generating
electric power, such as nearby coal mines, gas fields, and
hydroelectric areas.\66\ Many of these regions have taken the lead in
retail restructuring, while regions with historically low electricity
production costs have proceeded more cautiously or even affirmatively
decided not to change their retail access policies or to support their
local utilities' participation in regional programs at this time.\67\

93. One hallmark of electric industry restructuring has been the
growth of wholesale trade. In the past, wholesale power purchases made
up a small fraction of a large vertically integrated utility's power
supply, with most of its power needs met by its own generation. Today,
however, even large vertically integrated utilities rely increasingly
on wholesale purchases for their energy supplies. For example, as shown
in Table 1, between 1989 and 2000, generation by investor-owned
utilities grew from 2,132 thousand GWh to 2,230 thousand GWh, an
increase of less than 5 percent. During this time, wholesale power
purchases by these utilities almost tripled. Table 1 also shows that in
1989 wholesale power purchases provided 18 percent of the total
electric energy available to investor-owned utilities from both
wholesale purchases and their own generation. By 2000, wholesale
purchases provided over 37 percent of investor-owned utility electric
energy. This percentage has steadily increased since 1989, and is
expected to continue to grow as utility-owned plants are sold or
retired and new power supplies are acquired competitively in most parts
of the country.

Note: Data for 2001 is not yet available. Investor-owned utility
purchases include purchases from affiliates.
94. Table 1 demonstrates the increasing importance of competitive
wholesale energy acquisition in the United States electric power
industry, and the need for this Commission to ensure that transmission,
market rules and institutions are reformed as necessary to support the
new environment. It also makes clear that a retreat from competitive
markets to a cost-regulated vertically integrated world would be
difficult--the nation now depends increasingly on wholesale interstate
electricity markets.
95. Similar data are presented in Tables 2 and 3 for large public
power utilities and generation and transmission cooperatives that
generate at least some of their own power.\68\ These tables show that
wholesale purchases, on average, provide about 40 percent of the power
needs of these large utilities. Data are not presented for the smaller
public power and cooperative utilities because they typically do not
self-generate but buy all of their power at wholesale.
---------------------------------------------------------------------------
\68\ Note that the data available for large public power and
cooperative utilities is not complete but represents a sampling of
these utilities. The sample size typically grew each year so that an
apparent growth in the wholesale purchase percentages could reflect
the addition of smaller utilities that purchase more power at
wholesale.

96. The transition to competitive electricity markets is
characterized by opportunity and uncertainty. The promise of
competition is the opportunity to develop more innovative technologies,
improve services, lower average electric rates and provide more
customer choice than is likely under a strictly regulated monopoly
environment. During the transition to competition, these promises are
only partly fulfilled, and results vary regionally as a result of
different choices about retail restructuring. Additionally, the
California electricity crisis of 2000-2001, allegations of improper
trading practices, the collapse of Enron Corporation in December 2001
and the deteriorating financial health of many electric suppliers and
marketers at this time have added unprecedented uncertainty about, and
lack of confidence in, today's electric markets.
97. In addition to general concerns about adequate constraints on
the exercise of market power by power sellers, there is uncertainty in
the industry about impediments to new generators entering the market,
adequacy of incentives to build much needed generation and transmission
infrastructure, availability of non-discriminatory transmission service
for all sellers and buyers in a regional market and the risk of making
long-term commitments when market rules are subject to frequent
experiment and change. Differences in market rules between regions make
it difficult to transact business across regions and thus also lead to
increased uncertainty in the industry and the risk of market
manipulation.
98. Investors, generators and transmission providers are reluctant
to invest in new generation and transmission infrastructure if the
rules for setting energy or transmission prices are not yet known or
are subject to frequent revision.\69\ Thus, uncertainty about the
direction of competition policies inhibits the development of the very
infrastructure needed both to allow competition to work and to assure
reliability in a competitive environment. Customers are reluctant to
sign contracts for power or to change suppliers if long-term power
markets are unnecessarily volatile and they cannot obtain price
certainty.

Transmission Grid Study (May 2002), available in <http://
tis.eh.doe.gov/ntgs/ (hereinafter DOE National
Transmission Grid Study).
---------------------------------------------------------------------------
99. The promise of wholesale competition may go unfulfilled--or at
best continue to be delayed at great cost--unless many of these
uncertainties are resolved. This proposed rule is intended to help
resolve generically many of the uncertainties facing the electric power
industry and to restore confidence in future power markets.
D. Legal Authority and Findings
100. The primary purposes of the Federal Power Act are to curb
abusive practices by public utilities and to protect customers from
excessive rates and charges. To achieve these ends, section 205 of the
Federal Power Act requires that no public utility shall ``make or grant
any undue preference or advantage to any person or subject any person
to any undue prejudice or disadvantage,'' with respect to the
transmission of electric energy in interstate commerce or wholesale
sales.\70\ Section 206 of the Federal Power Act authorizes the
Commission
[[Page 55468]]
to investigate and remedy unduly discriminatory or preferential rules,
regulations, practices or contracts affecting public utility rates for
transmission in interstate commerce and for sales for resale of
electric energy in interstate commerce.\71\ It also authorizes the
Commission to investigate and remedy unjust and unreasonable rates,
charges or classifications, and any rules, regulations, practices or
contracts affecting such rates, charges or classifications.

\71\ 16 U.S.C. 824e.
---------------------------------------------------------------------------
101. Moreover, the Commission's regulatory authority ``clearly
carries with it the responsibility to consider, in appropriate
circumstances, the anticompetitive effects of regulated aspects of
interstate utility operations pursuant to [Federal Power Act sections]
202 and 203, and under like directives contained in [Federal Power Act
sections]
205, 206, and 207.'' \72\ The Commission's authority to
remedy undue discrimination and anticompetitive effects is broad.\73\
---------------------------------------------------------------------------
\72\ See Order No. 888 at 31,669 (quoting Gulf States Utilities
Co. v. FPC, 411 U.S. 747, 758-59, reh'g denied, 412 U.S. 944
(1973)). See also City of Huntingburg v. FPC, 498 F.2d 778, 783-84
(D.C. Cir. 1974) (finding that the Commission has a duty to consider
the potential anticompetitive effects of a proposed interconnection
agreement).
\73\ See Order No. 888 at 31,669 (the Federal Power Act fairly
bristles with concern for undue discrimination (citing Associated
Gas Distributors v. FERC, 824 F.2d 981, 998 (D.C. Cir. 1987), cert.
denied, 485 U.S. 1006 (1988))).
---------------------------------------------------------------------------
102. The Court of Appeals for the District of Columbia Circuit
reviewed challenges to Order No. 888 and found that the ``open access
requirement is authorized by and consistent with the [Federal Power
Act],'' and upheld the order.\74\ On appeal, the Supreme Court affirmed
the Commission in applying its open access requirements to transmission
used for wholesale and unbundled retail sales of electric energy in
interstate commerce, but also concluded that the Commission had
jurisdiction over transmission used for bundled retail sales of
electric energy in interstate commerce. The Supreme Court further
stated that the Commission may regulate bundled retail transmission of
energy as a means of addressing undue discrimination. While the Court
did not adopt the appellants' suggestions that the Commission's finding
of discrimination in the wholesale electricity market suggested the
presence of discrimination in the retail electricity markets,\75\ it
stated that ``[w]ere FERC to investigate this alleged discrimination
and make findings concerning undue discrimination in the retail
electricity market, Sec. 206 of the FPA would require FERC to provide a
remedy for that discrimination * * * And such a remedy could very well
involve FERC's decision to regulate bundled retail transmissions'' of
energy.\76\

103. We find that undue discrimination and anticompetitive behavior
persist, as detailed in Section III and Appendix C, in both wholesale
and retail transmission of energy. Pursuant to our statutory mandate to
remedy undue discrimination and anticompetitive effects in these
markets, as interpreted by the Supreme Court, we will apply the
requirements of this rule to the transmission component of bundled
retail transactions. At a minimum, all transmission service in
interstate commerce must be subject to the same non-discriminatory non-
rate terms and conditions in order to eliminate undue discrimination in
wholesale markets and in retail choice markets. With respect to rates
for bundled retail transmission service, however, we will work with
states to address difficult transition rate issues.
104. In light of these statutory responsibilities and authorities
under the Federal Power Act, we have assessed the state of the electric
utility industry and determined that it is necessary to act promptly to
provide stability to the industry and to assure that customers receive
adequate supplies of electric energy at the lowest reasonable price.
During the past six years, the implementation of open access
transmission under Order No. 888 has fundamentally altered the
landscape of the electric utility industry by removing major
discriminatory barriers to the use of the interstate transmission grid
and thereby opening the door to competition in wholesale electric power
markets. However, even with the Order No. 888 open access pro forma
transmission tariff and Order No. 889 transmission standards of conduct
in place, there continues to be undue discrimination in the provision
of interstate services. Experience under the pro forma tariff has
demonstrated that unduly discriminatory transmission practices continue
today. Further, existing trading rules and design of wholesale power
markets do not consistently prevent market manipulation or send proper
price signals to participants or allocate scarce resources to those who
value them most and thus could result in unjust and unreasonable rates.
Thus, competition either does not exist in many areas of the country or
competition is distorted.
105. We find that:
(1) the operation of the Commission's pro forma transmission tariff
(which is administered by vertically integrated as well as non-
vertically integrated public utilities such as ISOs) contains
provisions that, in practice, permit undue discrimination in the
provision of transmission services;
(2) public utilities that own, operate or control transmission
facilities and also participate in power markets continue to possess
substantial transmission market power and retain the ability to unduly
discriminate in the provision of transmission service and spot market
energy services;
(3) lack of standardized wholesale electric market design allows
undue discrimination within and across regions, can result in unjust
and unreasonable pricing and allocation of transmission and permits the
exercise of market power (and thus unjust and unreasonable rates) in
power markets; and
(4) proper price signals are not being sent to the marketplace,
with the result that market-based rates in many places are distorted,
and reasonably accurate price signals necessary for infrastructure
additions are not being sent.
106. To remedy remaining undue discrimination in the provision of
interstate transmission services and in other industry practices, and
to ensure just and reasonable rates for sales of electric energy within
and among regional power markets, the Commission proposes to modify the
Order No. 888 pro forma tariff to reflect non-discriminatory,
standardized transmission service and require standardized wholesale
electric market design. The Commission also proposes to expressly
exercise jurisdiction over all transmission in interstate commerce by
public utilities.
IV. The Proposed Remedy
107. The Commission's goal in Order Nos. 888 and 2000 was to
harness the benefits of competition for the nation's electricity
customers by assuring adequate and reliable supplies of electricity at
a just and reasonable price. As discussed above in the Need for Reform
section (Section III), the current rules and regulations have prevented
the full attainment of that objective. To address these problems in the
current system, we are proposing a comprehensive package of reforms
that are described more fully in this section.
108. Section III and Appendix C provide numerous examples of ways
that an entity that owns both
[[Page 55469]]
transmission and generation can discriminate in favor of its own
customers or generation under the current tariff. The problem stems
from the differences in the sets of rules that apply to users of the
transmission system. First, the current regulatory system allows
vertically integrated utilities to discriminate in favor of their
bundled retail load at the expense of wholesale customers. This occurs
because transmission service for bundled retail customers is subject to
different rules and rates than service for wholesale customers. Second,
the current distinction between Point-to-Point Transmission Service and
Network Integration Transmission Service also creates opportunities for
undue discrimination in favor of generation owned by the transmission
owner or an affiliate.
109. To remedy this discrimination we propose to place all
transmission customers under the same set of rules. We propose to place
transmission service for bundled retail customers under the same terms
and conditions of service as wholesale transmission service. To
accomplish this we propose to revise the existing pro forma tariff to
remove provisions that grant preferential treatment to transmission
service for bundled retail customers. We propose that all public
utilities that own, control or operate interstate transmission file
these interim changes no later than July 31, 2003. We also propose that
no later than September 30, 2004, or such date as the Commission may
establish, only Independent Transmission Providers would operate
Commission-jurisdictional facilities. This requirement will apply
whether or not the public utility that owns, controls or operates
interstate transmission facilities has joined an RTO.\77\ We are
proposing specific governance requirements that must be met by the
Independent Transmission Provider.
---------------------------------------------------------------------------
\77\ A Commission-approved RTO would meet the requirements of an
Independent Transmission Provider.
---------------------------------------------------------------------------
110. Also, no later than September 30, 2004, or such date as the
Commission may establish, we propose to eliminate the distinction
between Point-to-Point and Network Integration Transmission Services by
having one service, Network Access Service, that contains elements of
both types of service--the flexibility of Network Integration
Transmission Service and the tradability of Point-to-Point Transmission
Service. We propose these time periods to provide sufficient time for
the development of the necessary new software systems. Network Access
Service is based on an open spot market for imbalance energy and a
uniform congestion management methodology, i.e., LMP, to more
efficiently manage the transmission grid. The spot energy market and
LMP rely on management of the transmission system and bidding by supply
and demand resources attached to the transmission grid under market
rules and protocols.
111. To provide the price signals needed to manage congestion, the
Independent Transmission Provider will be required to operate a day-
ahead and real-time market for energy. To provide customers with a
mechanism for achieving price certainty under the new congestion
management system, we also propose to require that customers be given
Congestion Revenue Rights for their historical uses that protect
against congestion costs when specific receipt and delivery points are
used.
112. LMP and Congestion Revenue Rights will provide price signals
to indicate where new investment is needed; however, the price signals
alone may not guarantee sufficient investment. We also propose to
require a regional transmission planning and expansion process to
provide a backstop process for ensuring that needed transmission
construction is undertaken. We propose that this process begin six
months from the effective date of the Final Rule, even though much of
the country will not have had the opportunity to respond to LMP and
Congestion Revenue Rights for another few years.
113. At this stage of the industry's evolution, structural barriers
to competitive markets remain, so to address this we are proposing
market power mitigation measures for the spot markets that will be
operated by the Independent Transmission Provider. These measures are
designed to address the two significant structural problems in
wholesale energy markets--the existence of localized market power that
arises from transmission constraints, and the lack of price-responsive
demand. The market power mitigation proposal is a framework that can be
tailored to reflect the competitive conditions of the particular
region. It is designed to be reexamined annually and adjusted as needed
to reflect changes in the competitive structure of the region,
including a phasing out of mitigation measures as resource adequacy and
demand response develops. Because market power mitigation of spot
market prices will tend to suppress the price signals for new entry, we
are also proposing a non-price mechanism to assure that load meets a
long-term resource adequacy requirement.
114. To avoid the market design flaws discussed in the Need for
Reform section (Section III) and Appendix C and market manipulation in
Appendix E, and to minimize the potential for seams issues, we propose
a standardized tariff that incorporates the best practices and builds
on the lessons from our experience with organized markets. In Appendix
B, the proposed SMD Tariff standardizes many aspects of the basic
market design. However, it also allows flexibility in a number of areas
to customize the basic market design to meet regional requirements
where such customization will not lead to further discrimination or
inefficiencies.
115. We propose to permit small entities to seek waiver of the
Standard Market Design Final Rule requirements. The regulations we
propose include waiver provisions under which public utilities, and
non-public utilities seeking exemption from the reciprocity condition,
may file requests for waivers from all or part of the Commission's
regulations.
116. Finally, while we have attempted to standardize the basic
aspects of the market design policy, this proposed rule does not
include detailed business practices and communication protocols that
will be needed to administer Standard Market Design. We fully
appreciate the benefits of business practice standardization and, as we
did in the natural gas industry, we believe it is best if industry
participants develop these types of highly detailed and technical
standards. Thus, we are proposing a process, similar to that used in
the natural gas industry, that could be used for standardization of
business practices, data sets and communication protocols that includes
representation of all affected market participants. Upon its formation,
the Wholesale Electric Quadrant of the North American Energy Standards
Board (NAESB), working closely with Independent Transmission Providers
who would collectively serve in an advisory capacity to the board,
would produce business practice and electronic communication standards.
NAESB would notify the Commission when it has adopted standards, and
the Commission would then use rulemaking proceedings to propose the
incorporation of these standards by reference into the Commission's
regulations. If the industry is unable to reach consensus on a
particular standard, the Commission would be available to resolve the
dispute, so that the industry process can continue, or the Commission
could develop its own standards if necessary. Consistent with gas
industry regulation, issues of policy that affect significant resources
or that
[[Page 55470]]
may cause cost-shifting would be resolved at the Commission rather than
through the standard setting body.
A. The Interim Tariff
117. Standard Market Design is intended to cure undue
discrimination, in part, with respect to the use of the transmission
grid. As we discussed in Section III.B.2, there are different rules for
bundled retail transmission service and for wholesale and unbundled
retail transmission services. These differences result in unduly
discriminatory preferences for the vertically integrated transmission
owner's bundled retail customers.
1. Placing Bundled Retail Customers Under the Interim Tariff
118. We propose that to eliminate this undue discrimination, the
transmission component of bundled retail service must be taken under an
open access transmission tariff. Under the current pro forma tariff, a
vertically integrated utility is required to designate the resources it
uses to serve bundled retail customers in the same manner as wholesale
customers are required to designate network resources under the Network
Integration Transmission Service. We propose to use these designations
of network resources in converting service used to meet retail
obligations. The existing level of service would be provided pursuant
to the new Network Access Service. The load-serving entity or the
retail customer would receive either Congestion Revenue Rights or the
auction revenues for these rights for the currently designated
resources. In Section V of this Notice of Proposed Rulemaking, the
Commission sets forth a proposed time-line and implementation process
for this conversion process.
119. In the interim, however, we propose to require that bundled
retail load be placed under the existing pro forma tariff. While many
of the revisions required by Standard Market Design are dependent on
the production and adoption of software to determine locational
marginal prices and to operate markets, placing bundled retail load
under the existing pro forma tariff can be done immediately. This will
remove certain discriminatory practices and is the first step towards
placing all transmission service under one tariff. This will require
several revisions to the existing pro forma tariff to modify provisions
that define the different treatment granted to the service of bundled
retail load. Among the revisions that the Commission proposes to
require public utilities to file are revisions to Sections 1.19, 13.5,
13.6, 14.2, 22.1(a), 22.1(a), 28.2, 28.3, 33.2, 33.3, 33.3 and 33.5.
The specific changes are identified in Appendix A.
120. We propose that the public utilities file these revisions to
their tariffs and execute service agreements to take Network
Integration Transmission Service on behalf of their bundled retail load
no later than July 31, 2003. We recognize, however, that some public
utilities (e.g., ISOs) may already be serving bundled retail load under
the pro forma tariff. Accordingly, to the extent that a public utility
can demonstrate that it complies with this requirement, it may so
indicate in its compliance filing.
2. Additional Interim Revisions to the Pro Forma Tariff
121. Since the implementation of the existing pro forma tariff, the
Commission has offered clarifications to various provisions of the
tariff. Perhaps the most important of these dealt with a customer's
right to roll over its existing contract for long-term firm service
(Section 2, Initial Allocation and Renewal Procedures).
122. In several orders, the Commission clarified three significant
points: (1) A customer must submit a request to roll over its contract
no later than sixty days prior to the date the current service
agreement expires;\78\ (2) the public utility may only deny a customer
its right to roll over a contract due to future load growth if the
public utility includes in the original service agreement a specific,
reasonably forecasted need for the transfer capability to serve load
growth for network customers at the end of the term of the service
agreement;\79\ and (3) a long-term firm customer that requests to use
alternate point(s) of receipt or delivery retains its right of first
refusal for service at the original point(s) of receipt and delivery at
the time the current service agreement expires.\80\

123. These revisions have a significant impact on the rights of
current transmission customers and will continue to do so up until the
time the SMD Tariff, including auctions of Congestion Revenue Rights,
is in place.\81\ We propose to require public utilities to make the
tariff changes to Section 2.2 of the existing pro forma tariff, as
outlined in Appendix A.
---------------------------------------------------------------------------
\81\ The protections offered by rollover rights are of value in
a first-come, first-served priority system, and are valuable for a
direct allocation of Congestion Revenue Rights. Once Congestion
Revenue Rights are fully auctioned, and access to transmission
service will be based on a willingness to pay congestion costs (and
losses), it may no longer be necessary.
---------------------------------------------------------------------------
B. Independent Transmission and Markets
124. Another form of undue discrimination is the lack of
independence of the transmission provider in many regions of the
country. As discussed in Section III.B.1, remaining corporate ties
between generation and transmission within public utilities are
problematic since they allow the vertically integrated utility to
exercise market power to advantage its affiliated generation.
1. Independent Transmission Providers
125. To remedy this undue discrimination, transmission service must
be provided by an independent entity. Therefore, we propose to require
all public utilities that own, control or operate facilities used for
the transmission of electric energy in interstate commerce to: (1) Meet
the definition of Independent Transmission Provider, (2) turn over the
operation of its transmission facilities to an RTO that meets the
definition of Independent Transmission Provider, or (3) contract with
an entity that meets the definition of Independent Transmission
Provider to operate its transmission facilities.
126. An Independent Transmission Provider is any public utility
that owns, controls or operates facilities used for the transmission of
electric energy in interstate commerce, that administers the day-ahead
and real-time energy and ancillary services markets in connection with
its provision of transmission services pursuant to the SMD Tariff, and
that is independent (i.e., has no financial interest, either directly
or through an affiliate, in any market participant in the region in
which it provides transmission services or in neighboring regions).
127. We propose that affected public utilities must inform the
Commission which Independent Transmission Provider will operate the
public utility's transmission facilities no later than July 31, 2003.
However, a public utility that is a member of an approved RTO or ISO or
other entity that meets the definition of Independent Transmission
Provider may file a request for a waiver of the filing requirements of
this paragraph on the ground that it has already complied with the
requirement.
[[Page 55471]]
128. Any entity meeting the definition of Independent Transmission
Provider would file the SMD Tariff to provide transmission services,
including ancillary services, and to administer the day-ahead and real-
time energy and ancillary services markets. As discussed further below,
an Independent Transmission Provider would also perform market
monitoring and market power mitigation, long-term resource adequacy and
transmission planning and expansion on a regional basis.
129. An Independent Transmission Provider would also file under
section 205 any changes to transmission rates necessary to implement
Standard Market Design, no later than 60 days prior to the date on
which it proposes to implement Standard Market Design.
130. In addition, one or more public utilities may jointly file an
application to meet the requirements of Standard Market Design. Also,
an Independent Transmission Provider may make necessary filings on
behalf of public utilities required to meet the requirements of this
paragraph.
131. We seek comment on whether this remedy is adequate to remove
the potential for unduly discriminatory behavior on the part of a
vertically integrated transmission provider. Can the requirements of
Standard Market Design be satisfied either by performing the function
through an RTO or contracting with an independent entity to perform
them? Given that most transmission providers have filed proposals to
join an RTO, is a non-RTO compliance option necessary to cure undue
discrimination and produce just and reasonable rates for transmission
service and the sale of electric energy?
2. Role of Independent Transmission Companies in Standard Market Design
132. We have long recognized that the Independent Transmission
Company (ITC) business model can bring significant benefits to the
industry. Their for-profit nature with a focus on the transmission
business is ideally suited to bring about: (1) Improved asset
management including increased investment; (2) improved access to
capital markets given a more focused business model than that of
vertically integrated utilities; (3) development of innovative
services; and (4) additional independence from market participants. We
believe that these characteristics of ITCs can have significant
benefits for the implementation of Standard Market Design, particularly
in the areas of development of transmission infrastructure and
structural independence from market participants.
133. The Commission recently approved a proposal by several
transmission owners to form an ITC, TRANSLink Transmission Company, LLC
(TRANSLink), to share responsibility with the Midwest ISO Regional
Transmission Organization (the Midwest ISO) \82\ and other regions for
the RTO functions prescribed in Order No. 2000. In that proceeding, the
Commission approved a hybrid RTO formation under which specific RTO
functions were delegated to either the RTO or the ITC. Regarding the
delegation of functions we stated:
---------------------------------------------------------------------------
\82\ TRANSLink Transmission Company, L.L.C., et al., 99 FERC
[para]
61,106 (2002).
Our rulings on the allocation of functions issues are based on
our belief that for effective RTO operations, regional trading, and
one-stop shopping, a single transmission provider must have overall
authority and ultimate responsibility for transmission service in
the region. We further believe that the security-constrained,
economic dispatch needed for an efficient and reliable market is
best operated by an independent regional transmission provider.
However, we believe that it is acceptable for some functions with
predominantly local characteristics to be delegated to an ITC so
long as the RTO has oversight authority in the event that local
actions have a regional impact. We find that this is critical to
successful RTO development and especially important given the
characteristics of the interstate transmission grid. It has become
increasingly evident in recent years that even seemingly local
issues, such as generator location or isolated transmission
bottlenecks, can and do impact the larger grid, and that is why we
believe that centralized RTO oversight is needed.
We also remain concerned that vesting control into sub-regional
entities may create seams which could easily lead to re-
balkanization. These difficult delegation decisions are made with
our firm belief that ITCs can flourish under the RTO umbrella and
that in performing certain delegated functions, ITCs will be able to
effectively manage their assets, protect their value, and bring
their expertise to increase efficiencies and enhance the value of
their business. Nevertheless, these delegation decisions should not
prevent ITCs from seeking additional authority, subject to
Commission approval, at a later date after ITCs have gained
experience under RTO operations.\83\ We are also guided by the
premise that any delegation of functions to an ITC must be
consistent with and further the Commission's goals in the SMD
Proceeding. We assume in this order that the Midwest ISO will be the
transmission provider in the TRANSLink area and will operate a real-
time and day-ahead market, or any functions that are required under
the SMD final rule.\84\
\83\ We recognize that as the Midwest ISO and ITCs gain
experience, they should, from time to time, reassess the assignment
of the functions and reevaluate whether some that have been
delegated to a local level need to be performed at a regional level
and vice versa. Likewise, after SMD is implemented, the assignment
of functions may need to be reassessed. (Footnote 37 in original).
\84\ TRANSLink, 99 FERC at 61,463.
---------------------------------------------------------------------------
134. We seek comment on the functions that an ITC should perform
under Standard Market Design. Should the Commission retain the same
delegation of functions that was approved in TRANSLink? Are there
elements of the proposed Standard Market Design that would justify a
different delegation of functions? Should an ITC qualify as an
Independent Transmission Provider?
135. We seek comment on whether an ITC that has no ties to a Market
Participant, as defined in this proposal, is sufficiently independent
to act as the Independent Transmission Provider. The ITC may hold grid
assets such as transmission facilities and Congestion Revenue Rights
and may be allowed a performance-based ratemaking program. Thus the
Commission is concerned that the ITC may unduly discriminate in favor
of its own transmission interests when carrying out operational and
planning decisions in its role as Independent Transmission Provider. We
seek comment on whether such ITC interests in transmission investment
may cause the ITC to unduly discriminate in day ahead or real time
markets operations or to discount generation, demand response, and
other transmission owners' (e.g., merchant transmission) solutions to
grid problems. On the other hand, generation and demand response
solutions are likely to have the first opportunity to respond to LMPs
if it makes economic sense to do so, given the difficulty in siting
transmission. Given the planning process and stakeholder input, as well
as the Commission's authority to set rates, we seek comment on what
specific ways an ITC could make such unduly discriminatory decisions?
The Commission is convinced that, if its role is appropriately defined,
and opportunities for undue discrimination are addressed, the ITC shows
great promise to address grid problems through profit driven
activities. One such activity could be reducing congestion where an ITC
with properly structured performance based rates would have an
incentive. What is the appropriate role for the ITC?
C. The New Transmission Service
136. To address the discrimination described in Section III above
and in Appendix C, we will require Independent Transmission Providers
to provide a nondiscriminatory, standard transmission service to all
customers.
[[Page 55472]]
This new service, Network Access Service, combines features of both the
existing open access transmission services--Network Integration
Transmission Service and Point-to-Point Transmission Service. The
Network Access Service is grounded in the flexibility of network
integration transmission service, but adds a measure of reassignability
similar to that available under firm Point-to-Point Transmission
Service. Thus, Network Access Service will give all customers the
opportunity to have tradable Congestion Revenue Rights \85\ that will
expand their transmission options and enhance competition in wholesale
electric markets. It also will result in all transmission services
being performed under a single set of rules.
---------------------------------------------------------------------------
\85\ Congestion Revenue Rights entitle the holder to receive
specified congestion revenues in the day-ahead market. To the extent
that a customer's real-time schedule coincides with its day-ahead
schedule and its Congestion Revenue Rights, these rights offer
complete protection against uncertain congestion charges.
---------------------------------------------------------------------------
137. To complement Network Access Service and implement the
Standard Market Design, Independent Transmission Providers will manage
congestion using LMP. Management of transmission grid congestion is
difficult to do through bilateral transactions alone; thus a spot
market is required to manage congestion efficiently. We believe that
congestion management, balancing of load and generation in real time,
and the provision of ancillary services can be accomplished most
reliably and efficiently by a bid-based, security-constrained spot
market.
138. In addition to administering a spot market to manage
congestion, the Independent Transmission Provider will also use it to
handle imbalances and the procurement of ancillary services. The
Independent Transmission Provider would operate markets for energy,
regulation, operating reserve--spinning and operating reserve--
supplemental. These markets would be security-constrained, bid-based
markets operated in two time frames: (1) A day ahead of real-time
operations, and (2) in real time. Transmission services will be
scheduled through the day-ahead and real-time markets. The Independent
Transmission Provider would establish schedules for transmission
service, and sales and purchases of energy, regulation, and both
operating reserves, to ensure the most efficient use of the
transmission grid. Although the Independent Transmission Provider will
not be required to operate an organized market for either short- or
long-term bilateral transactions, its scheduling process must
accommodate such bilateral trades.
1. Basic Rights
139. Network Access Service builds upon the existing Order No. 888
Network Integration Transmission Service and will be available to all
eligible customers. As with Network Integration Transmission Service,
Network Access Service offers flexible use of the transmission grid--it
allows the load-serving entity to choose to serve its load with any
available resource on the system (or access any interface to import
power from a neighboring system), consistent with the Network Resource
Interconnection Service discussed in the Generator Interconnection
proposed rule.\86\ Network Access Service allows a customer to have the
Independent Transmission Provider integrate, dispatch and regulate the
customer's current and planned resources to serve its load as is
currently done under the pro forma tariff. Customers, including
generators and marketers, can also use this service for through-and-out
service, to aggregate resources for resale, and to perform hub-to-hub
transactions similar to Point-to-Point Transmission Service. In
addition, Network Access Service allows the customer (1) to trade
(reassign) its Congestion Revenue Rights and (2) to access points,
which, under the current pro forma tariff, are secondary points that
may be fully subscribed, by paying all applicable congestion charges.
---------------------------------------------------------------------------
\86\ Standardization of Generator Interconnection Agreements and
Procedures, FERC Stats. & Regs. [para]
32,560. Network Resource
Interconnection Service requires that sufficient network upgrades be
built so that interconnecting generators can serve load as a Network
Resource, as defined by the existing pro forma tariff.
---------------------------------------------------------------------------
140. Network Access Service is premised on dispatching of the
regional transmission grid so that the customers that value
transmission service the most will get it. All requested transactions
must be physically feasible under a security-constrained dispatch.
Where there are transmission constraints, the LMP system we propose
will price out all transactions and redispatch available generation as
needed to accommodate all requests for service.\87\
---------------------------------------------------------------------------
\87\ In all but limited cases, this should allow the Independent
Transmission Provider to satisfy all requests for service by
customers willing to pay the applicable congestion charges.
---------------------------------------------------------------------------
141. Network Access Service gives the customer the right to
transmit power between any number of combinations of receipt and
delivery points. A receipt point is defined here as the location where
a transaction originates, and a delivery point is defined as the
location where a transaction terminates. Receipt and delivery points
include both individual nodes as well as aggregated points, e.g.,
trading hubs. Thus, a Network Access Service customer could use this
service to move power from a generator (receipt point) to a load
(delivery point), from a generator (receipt point) to a trading hub
(delivery point), from one trading hub to another, or from a trading
hub (receipt point) to a load (delivery point). A Network Access
Service customer would have access to all receipt and delivery points
on the system and would be able to substitute receipt points on a daily
or hourly basis through the day-ahead and real-time scheduling
processes.
142. Any customer using transmission service, whether a load-
serving entity, generator, or marketer, would take Network Access
Service. However, as explained more fully in Section IV.D.1, only those
customers taking power off of the grid would pay the access charge.
(All customers would pay congestion costs and losses associated with
their particular transaction.) We expect that, in most instances, it
would be a load-serving entity, rather than a generator or marketer,
that would be the customer for transactions that result in power
leaving the grid, and thus, the load-serving entity would be the entity
paying the access charge.\88\
---------------------------------------------------------------------------
\88\ An end-use customer in a state with retail access could be
the entity taking transmission service and paying the access charge.
---------------------------------------------------------------------------
2. Access to Transmission Service
143. Under the existing pro forma tariff, ``firm'' transmission
service implies certainty both with respect to delivery and price. Once
a customer taking firm service under the existing pro forma tariff
agrees to pay the transmission rate and schedules service, it has full
assurance that it will be able to transmit power between its chosen
receipt and delivery points without service interruption (absent force
majeure or curtailment) and without being subject to any additional
costs (e.g., redispatch). However, there are times when a transmission
provider cannot offer a guarantee of service availability (absent the
long-term solution of a customer agreeing to pay for system expansion).
At these times, under the existing pro forma tariff, only non-firm
transmission service (which can be interrupted for economic
reasons)\89\ is available at the stated maximum rate. Thus, the
existing pro forma transmission service begins with the basic premise
of price certainty, but includes a measure of uncertainty
[[Page 55473]]
regarding service availability that is resolved only if firm service
can be secured. In sum, the customer is generally assured of the rate
it will pay for transmission service, but, unless it has secured firm
transmission service between the specified points, is not necessarily
assured that it will receive transmission service.
---------------------------------------------------------------------------
\89\ All services, including firm service, can be curtailed for
reliability reasons.
---------------------------------------------------------------------------
144. With Network Access Service, all customers who want physically
feasible service will be able to receive service; however, uncertainty
can arise as to the rate paid to receive the service. In addition to
the access charge (which recovers the embedded costs of the
transmission system), the customer would be subject to the cost of
congestion between its chosen receipt and delivery points. To achieve
certainty with respect to price and avoid congestion costs, the
customer would have to acquire the Congestion Revenue Rights associated
with its specific receipt point-delivery point combination(s).\90\
Thus, Network Access Service, coupled with Congestion Revenue Rights
for the desired points, provides the customer with certainty with
respect to delivery and price, comparable to the existing pro forma
tariff's firm service.
---------------------------------------------------------------------------
\90\ Congestion Revenue Rights provide the rights holder with
the revenues associated with congestion between the associated
points; thus, any congestion costs it pays are fully offset by these
revenues. To the extent the Congestion Revenue Rights holder opts
not to schedule transmission service at those points, it would still
receive the congestion revenues.
---------------------------------------------------------------------------
145. Accordingly, customers desiring service comparable to (but
actually more dependable than) existing firm transmission service would
need to acquire Congestion Revenue Rights for their receipt and
delivery points and schedule service between those points in the day-
ahead market. With the allocation process we propose in Section IV.H.2,
customers under existing contracts will receive Congestion Revenue
Rights that match their current use of the system, which will ease and
simplify the conversion process. Customers using non-firm transmission
service under the existing pro forma tariff could request service when
needed in the day-ahead or real-time markets. To the extent the
customer is willing to pay congestion costs and transmission losses,
its requested transmission service would be available and provided.\91\
A customer also has the option of placing a limit on the amount of
congestion charges it is willing to pay--to the extent that amount is
exceeded, the customer would not take transmission service for that
receipt point-delivery point combination during the requested time
period. This means no separate non-firm transmission service option is
needed under Network Access Service.
---------------------------------------------------------------------------
\91\ As discussed in Section IV.D.3, customers exporting power
from or transmitting through one region would not be subject to that
region's access charge, but would be liable for the cost of
congestion and transmission losses associated with its transaction.
---------------------------------------------------------------------------
3. Service Limitations in the Existing Pro Forma Tariff
146. The existing pro forma tariff limits how the Network
Integration Transmission Service and Point-to-Point Transmission
Service can be used. It limits the use of interface capability by
Network Integration Transmission Service customers to the amount of the
customer's load. Under the LMP system that we are proposing,
transmission service would be available to any customer up to the full
amount of the transfer capability, so long as the customer is willing
to pay the applicable congestion charges. The specifics of scheduling
power across interfaces is discussed in a later section.
147. The existing pro forma tariff also requires the network
customer to take Point-to-Point Transmission Service for any additional
third-party sales transaction or to serve load on another transmission
provider's system. This will no longer be necessary with Network Access
Service, which will be used for all transmission services, including
third-party sales transactions and transmission service for load on
another transmission provider's system. A customer, however, may prefer
to have separate service agreements for service to particular loads for
accounting or tracking purposes.
4. Conditions for Receiving Service
148. To receive Network Access Service, a customer must meet the
same requirements as those under the existing pro forma tariff for
acquiring the right to schedule transmission service: all customers
must meet creditworthiness and other eligibility standards, complete an
application for service, and meet certain operating standards (e.g.,
reliability maintenance of customer-owned facilities for integration
with the transmission provider's system, including metering and
communications equipment) as defined in the current pro forma tariff.
Similarly, the customer must have a service agreement to take service
under the tariff. A load-serving entity would also need a network
operating agreement, which would detail how the Independent
Transmission Provider's system under the SMD Tariff and the load-
serving entity's system would work together (similar to a generator
interconnection agreement).\92\ These standards are largely unchanged
from the existing pro forma tariff. In addition, the customer must
agree to pay any congestion charges and transmission losses associated
with its request \93\ and any customer serving load located within the
Independent Transmission Provider's system must agree to pay the
applicable access charge.
---------------------------------------------------------------------------
\92\ Consistent with the existing pro forma tariff, a Network
Access Service customer would retain the right to request that the
Independent Transmission Provider file an unexecuted transmission
agreement or network operating agreement if the two parties cannot
agree on the terms and conditions of service.
\93\ As noted earlier and more fully explained in Section
IV.E.3., a customer can protect itself against the costs of
congestion by acquiring Congestion Revenue Rights in the amount of
its load and between the receipt/delivery points where its desired
resources and loads are located.
---------------------------------------------------------------------------
5. Scheduling Transmission Service and Acquiring Congestion Revenue
Rights
149. As noted above, a customer would acquire Congestion Revenue
Rights to assure price and delivery certainty for its transactions.
Anyone can hold Congestion Revenue Rights. Congestion Revenue Rights
can be acquired through a variety of means, including: (1) Direct
allocation that is based on some measure of current or historical
rights to the system; (2) periodic auctions; or (3) some combination of
these methods. The initial process for acquiring these rights is
discussed in Section IV.H.2.
150. Transmission service will be scheduled through the day-ahead
market with deviations accounted for in the real-time market, as
discussed in later sections. These scheduling opportunities are
comparable to the existing pro forma tariff's requirements (e.g., firm
point-to-point transmission service scheduled by no later than 10 a.m.
the day before, with schedules submitted after that time accommodated,
if practicable, and allowance to make changes to that ``day-ahead''
schedule prior to the start of the next clock hour). However, the new
service synchronizes the scheduling of transmission service and energy,
and relies on a transmission customer holding Congestion Revenue Rights
or its willingness to pay the cost of congestion, rather than on a
firm/non-firm, first-come, first served method, to ration capacity.
151. A Network Access Service customer would have to indicate the
location of its receipt and delivery points when it schedules service
in the day-ahead or real-time markets.\94\ If a
[[Page 55474]]
customer holds Congestion Revenue Rights between a set of receipt and
delivery points in the day-ahead market, but later decides to take
transmission service between a different set of points, the customer
would no longer have full protection against congestion costs for its
transaction in the day-ahead market and could incur different
congestion costs than the congestion revenues associated with the
Congestion Revenue Rights it holds. Similarly, to the extent that a
customer's real-time transactions differ from its day-ahead schedule,
the customer would be liable for any redispatch costs that occur in
real time that are necessary to accommodate its real-time transactions.
---------------------------------------------------------------------------
\94\ Further, consistent with the existing pro forma tariff and
the Commission's decision regarding ``tagging,'' the customer must
identify the ultimate source and sink so that the various system
operators in an interconnection can assess the simultaneous
feasibility of all scheduled power flows. See Coalition Against
Private Tariffs, 83 FERC [para]
61,015 at 61,040, reh'g denied, 84
FERC [para]
61,050 (1998).
---------------------------------------------------------------------------
6. Designating Resources and Loads
152. The existing pro forma tariff allows a Network Integration
Transmission Service customer to designate resources that the customer
owns or has committed to purchase pursuant to an executed, non-
interruptible contract. The transmission provider must then plan and
operate its system to be able to provide firm transmission service from
these resources to the customer's load. Under the proposed Standard
Market Design, the reservation of capacity for service is no longer
required, since a transmission customer pays the congestion cost for
transmission service. Thus, there is no longer a need for a Network
Access Service customer to designate network resources to get
transmission service. While the integration of resources and loads
(including behind-the-meter generation) that occurs under Network
Integration Transmission Service will continue, a Network Access
Service customer will now request receipt and delivery points through
the day-ahead scheduling process and real-time transactions.
153. Thus, we believe that the requirement to designate network
resources to receive transmission service may no longer be needed.
Further, we note that under the existing pro forma tariff the
designation of network resources was used in addressing long-term
resource adequacy concerns and in the planning process undertaken to
ensure that the resources could be integrated. Because we are now
proposing a resource adequacy requirement and a regional planning
process to meet these requirements, the requirement to designate
network resources may no longer be needed. (See Section IV.J). We
request comment on whether designating network resources and loads is
necessary for Network Access Service, particularly with respect to
performing the integration of resources and loads.\95\ Similarly, with
respect to the information required to complete an application for
service (Section 2 of the SMD Tariff), is it necessary for the
Independent Transmission Provider to request information beyond the
identity of and contact information for the customer, service term and
commencement date, and receipt and delivery points for the requested
service? Does the Independent Transmission Provider need to collect for
each service request (but not for each transaction) the location and
characteristics of the generation serving the load, detailed
descriptions of the load and the customer's transmission system and
owned generation?\96\ In sum, do we need separate procedures for
service to customers such as marketers, who do not serve load or own
generation, or transmission systems and load-serving entities that have
all these things? Does the integration aspect of Network Access Service
require different information to be provided to the Independent
Transmission Provider in order to initiate service? Should this
information be provided through other means, and what would that be?
---------------------------------------------------------------------------
\95\ The relevant sections of the SMD Tariff are Sections B.3
and B.4. While we believe that they may no longer be necessary, they
remain in the tariff for ease of reference during the proposed
rulemaking process. In the Final Rule, the Commission will determine
if these or similar provisions need to be included in the SMD
Tariff.
\96\ See Sections B.2.2.1(iv) and (v), and Sections B.2.2.2(iii)
through (vi) of the SMD Tariff.
---------------------------------------------------------------------------
7. Substituting Receipt and Delivery Points
154. Under the existing pro forma tariff, choosing alternate
resources to meet load required, in effect, placing a request in the
queue for new service. If firm capacity were available, the customer
would be permitted to use alternate points of receipt (or delivery) on
a firm basis. If firm capacity were not available, the customer could
choose the point(s) on a secondary, or non-firm, basis.
155. With Network Access Service, this process is no longer
necessary. A Network Access Service customer can essentially access any
point simply by requesting it through the day-ahead scheduling process
or real-time transactions (and be willing to pay congestion costs and
losses). To the extent the customer wanted to avoid the cost of
congestion for the transaction, it could retain its existing Congestion
Revenue Rights and acquire additional Congestion Revenue Rights for its
new receipt and delivery points through an auction or secondary market.
156. Alternatively, the customer could request a
``reconfiguration'' of the Congestion Revenue Rights it holds, i.e.,
the customer could turn in the Congestion Revenue Rights for the old
receipt and/or delivery point and request Congestion Revenue Rights
from the new receipt point or to the new delivery point. We seek
comment on the MW quantity of reconfigured Congestion Revenue Rights
that the customer should be entitled to receive. There are at least
three options. One option is to allocate to the customer the MW
quantity that is available specifically as a result of turning in the
old Congestion Revenue Rights. Under this option, the customer would
receive rights that become available by turning in the old Congestion
Revenue Rights. In such a case, the MW quantity of new Congestion
Revenue Rights might be different (either larger or smaller) than the
MW quantity of the old Congestion Revenue Rights.\97\ A second option
is to allocate any MW quantity of new Congestion Revenue Rights that
are physically feasible (i.e., it does not adversely affect the
Congestion Revenue Rights held by any other customer), including
Congestion Revenue Rights that were available before turning in the old
Congestion Revenue Rights. The MW quantity of new Congestion Revenue
Rights under this option could also be different (either larger or
smaller) than the MW quantity of older Congestion Revenue Rights. A
third option is to allocate a MW quantity of new Congestion Revenue
Rights that is either equal to the MW quantity of the old Congestion
Revenue Rights, or, if that is not physically feasible, the
[[Page 55475]]
largest MW quantity that is physically feasible. Under this third
option, the MW quantity of new Congestion Revenue Rights could never
exceed the MW quantity of the old Congestion Revenue Rights. The
process for acquiring and reconfiguring Congestion Revenue Rights is
further described in Section IV.E.3.
---------------------------------------------------------------------------
\97\ For example, a customer holding a 10 MW Congestion Revenue
Right from A to B may want to exchange its existing rights for
Congestion Revenue Rights from C to D. Suppose that both the A-to-B
and C-to-D Congestion Revenue Rights relied on a common congested
flowgate, so that the amount of A-to-B Congestion Revenue Rights and
C-to-D Congestion Revenue Rights is limited by the capacity of the
flowgate. However, suppose that the A-to-B Congestion Revenue Right
relies more heavily on the congested flowgate than the C-to-D
Congestion Revenue Right. That is, the proportion of the power flow
(known as the ``power flow distribution factor'') over the flowgate
in transmission service from A to B is greater than the proportion
in transmission service from C to D. Thus, giving up 10 MW of A-to-B
Congestion Revenue Rights may create the ability to award more than
10 MW of Congestion Revenue Rights (e.g., 15 MW) from C to D.
Conversely, a customer with 15 MW of C-to-D Congestion Revenue
Rights could exchange them for only 10 MW of A-to-B Congestion
Revenue Rights.
---------------------------------------------------------------------------
8. System Impact and Facilities Studies
157. Most service requests will be resolved through the day-ahead
security-constrained dispatch. Nevertheless, the Independent
Transmission Provider will need to conduct system impact and/or
facilities studies for service involving the interconnection of a new
load or generator. The Independent Transmission Provider will also
routinely perform simultaneous feasibility studies to determine the
configurations of Congestion Revenue Rights that can be accommodated.
Thus, except for adding references to the simultaneous feasibility
studies that will be performed in response to requests for Congestion
Revenue Rights, sections of the existing pro forma tariff addressing
various studies will remain largely unchanged. However, as discussed in
Section IV.C.8, these studies are now required to be performed by an
Independent Transmission Provider.
9. Load Shedding and Curtailments
158. Under the existing pro forma tariff, load shedding and
curtailment procedures were developed for inclusion in individual
network operating agreements. These procedures should be uniform and,
therefore, will be included in the SMD Tariff. In addition, we expect
that the majority of constraints will be resolved through the LMP-based
congestion management system, with only localized emergency/reliability
contingencies (transmission line outage into a load pocket) needing to
be addressed through load shedding or curtailment procedures.
159. This is a major improvement over the current tariff, as it
should eliminate most or all TLRs. To the extent practicable, when
system conditions require curtailment (in real time) that cannot be
resolved through the congestion management system, the Independent
Transmission Provider should curtail the customers whose transactions
contribute to the constraint on a pro rata basis.\98\ In addition, we
propose that to the extent the Independent Transmission Provider is
unable to schedule all requests for service made through the day-ahead
scheduling process, those customers with Congestion Revenue Rights for
their requested receipt point-delivery point combinations should be
scheduled first. We seek comment as to whether this scheduling priority
is appropriate. While it would grant Congestion Revenue Rights holders
an additional measure of certainty of delivery, would this undermine
the benefits of having a single transmission service for all customers?
---------------------------------------------------------------------------
\98\ Because we are now proposing to exercise our jurisdiction
over the transmission component of bundled retail transactions and
to provide a single set of rules and regulations that apply to all
transmission service, the limitation imposed by the United States
Court of Appeals for the Eighth Circuit on the Commission's
curtailment authority over bundled retail customers is no longer
relevant. See Northern States Power Company (Minnesota) and Northern
States Power Company (Wisconsin), 83 FERC [para]

remand, 89 FERC [para]

---------------------------------------------------------------------------
160. We propose that an Independent Transmission Provider can
assess a penalty for failure to curtail if a transmission customer
fails to curtail after reasonable notice. The proposed penalty is the
locational marginal price plus $1000 per MWh. The Commission has
approved a minimum notice period of ten minutes if the curtailment is
for reliability purposes.\99\ We request comment on whether the
Commission should continue this practice.

---------------------------------------------------------------------------
161. We also note that the Commission required transmission
providers to incorporate procedures for addressing curtailment of
parallel flows involving more than one transmission system (i.e., the
Transmission Loading Relief Procedure developed by NERC) as a single
generic amendment to the pro forma tariff.\100\ Under Network Access
Service, procedures for addressing non-discriminatory curtailment of
parallel flows will continue to be needed under emergency conditions
when the use of a regional congestion management procedure set out in
this proposed rule does not completely relieve a constraint.\101\
Language has been added to Section 9.3, Curtailments of Scheduled
Deliveries, to reflect this change.

Standard Market Design.
---------------------------------------------------------------------------
10. Trading (Reassigning) Congestion Revenue Rights
162. Network Access Service adds the tradability that currently
exists for ``firm'' Point-to-Point Transmission Service, but was not
available under Network Integration Transmission Service. Customers may
be able to acquire Congestion Revenue Rights from a particular receipt
point to a particular delivery point directly from the Independent
Transmission Provider, through a formal auction, or through secondary
markets. Once a customer has these point-specific Congestion Revenue
Rights, the customer may sell them at any time to another entity,
whether or not that entity intends to transmit power. The sale could be
for all or a portion of the amount or duration of the Congestion
Revenue Rights. All resales of Congestion Revenue Rights must be
reported on and conducted through the OASIS. As is currently the case
in some ISOs, Congestion Revenue Rights will be traded at the price at
which purchasers value the rights. The procedures for the auctions and
resale of Congestion Revenue Rights are discussed in Section IV.E.3.
163. We seek comment as to whether all Congestion Revenue Rights
must be sold through the OASIS, or whether some bilateral sales may be
made and only reported through OASIS after the sale.
11. Ancillary Services
164. The ancillary services provided as part of the current pro
forma tariff will largely remain the same under Network Access Service.
However, certain ancillary services will be provided through organized
markets with appropriate market power mitigation, as discussed infra.
The ancillary services markets are discussed in Sections IV.F.1.d and
IV.F.3.b.
D. Transmission Pricing
165. The Commission seeks to ensure transmission owners the
opportunity to recover their revenue requirements for their
transmission systems under Network Access Service. This charge could
either be a license plate rate (charge depends on zone of delivery) or
a postage stamp rate (same rate applies for all load within the
Independent Transmission Provider's service area) and would be paid by
all entities serving load within the Independent Transmission
Provider's service area. Moreover, to facilitate trading across
regions, we are proposing to change our policy on pricing of
transactions that start and end in different transmission systems.
166. In addition, we are proposing to refine our policy on pricing
of transmission expansions to provide incentives for market-driven
solutions. To facilitate the addition of much needed transmission
infrastructure, we
[[Page 55476]]
propose a regional approach to transmission expansion which includes
extensive participation by Regional State Advisory Committees \102\ to
identify the beneficiaries of a proposed expansion and how costs for
that expansion should be recovered.
---------------------------------------------------------------------------
\102\ Regional State Advisory Committee as discussed more fully
in Section IV.K.
---------------------------------------------------------------------------
1. Recovery of Embedded Costs
167. Under the existing pro forma tariff, there are two types of
transmission services--Network Integration Transmission Service, which
is designed for the integration of resources and loads, and Point-to-
Point Transmission Service, which is generally used to export power
from one transmission system to another (through-and-out service).
168. To recover the embedded costs of the transmission grid, the
Commission has historically permitted transmission providers to assess
an access charge, in the form of a load ratio share charge or a per kW
per month charge, on all transactions taking place on the transmission
provider's system.\103\ For a single transmission utility, these
charges usually take the form of a ``postage stamp'' rate (i.e., the
same charge for all customers'' use of the utility's grid) and, for an
ISO or RTO, a ``license plate'' rate (i.e., a different charge for the
use of the entire regional transmission system that is based on the
revenue requirement of the transmission owner's facilities, or
``zone,'' where the transaction sinks).\104\ The access charge is
assessed on all transactions making use of the transmission provider's
system, including transactions where the generator and load are located
within the transmission provider's system and where either the
generator or the load (or both) are located outside of the transmission
provider's system.
---------------------------------------------------------------------------
\103\ A Network Integration Transmission Service customer pays a
monthly demand charge based on its load ratio share of the
transmission provider's monthly transmission revenue requirement.
The customer's load ratio share is based on the customer's hourly
load coincident with the transmission provider's monthly
transmission system peak. The firm Point-to-Point transmission
customer pays a monthly demand charge for each unit of capacity that
it has reserved.
\104\ Both PJM and New York ISO use a license plate rate design.
PJM and New York ISO have different rate designs for exports and
wheel-through services. PJM uses a weighted average of the charges
of all transmission for these types of transactions. New York ISO
uses the transmission charge of the owner of the intertie that
serves as the point of delivery to the adjacent system.
---------------------------------------------------------------------------
169. While this method of pricing has been effective in recovering
a transmission provider's revenue requirement, some changes are
required to reflect the new Network Access Service and to address
unintended consequences of the current rate design. First, we propose
that transmission owners recover embedded costs through an access
charge assessed mainly to load-serving entities, based on their
respective shares of the system's peak load, i.e., their load ratio
shares. Our goal is to minimize the distorting effects that an access
charge can have on economic choices. We propose to assess access
charges primarily on loads, but not on generators, because the economic
choices of loads (such as where to locate) are less likely to be
affected by access charges than are the choices of generators.\105\
Moreover, even if access charges were imposed on generators or other
market participants, it is likely that they would pass along most or
all of their access charges to their customers, so that loads would
ultimately bear most or all of the transmission fixed costs.
---------------------------------------------------------------------------
\105\ Point-to-Point customers wanting to receive a direct
allocation of Congestion Revenue Rights would also pay the access
charge, as discussed below.
---------------------------------------------------------------------------
170. Second, we propose to eliminate all ``rate pancaking,'' which
involves charging separate embedded cost charges for moving power over
separate Independent Transmission Provider service areas. We propose to
eliminate rate pancaking both within an Independent Transmission
Provider's service area and between service areas. Rate pancaking
impedes the ability of distant generators to compete with nearby
generators by imposing charges to transmit energy from distant
generators that are unrelated to actual variable transmission costs.
Assessing the access charge primarily to load-serving entities based on
their load ratio share rather than on the number of service areas over
which energy is transmitted increases generation competition by
allowing distant generators to compete more easily with nearby
generators.
171. As discussed further below, we propose that customers paying
access charges would receive Congestion Revenue Rights (or
alternatively, revenues from the auction of Congestion Revenue Rights).
Thus, in exchange for paying the fixed costs of the transmission
system, those paying access charges would receive the financial
benefits--the stream of congestion revenues--resulting from usage of
the transmission system. In addition, we seek to minimize cost shifts
that could result from our proposal, and we propose to maintain as much
as possible the explicit and implicit transmission rights currently
held by customers. Thus, customers currently receiving Network
Integration Transmission Service and firm Point-to-Point Transmission
Service under the existing pro forma tariff would receive Congestion
Revenue Rights based on their existing service levels. However, there
are two issues regarding access charges and the allocation of
Congestion Revenue Rights on which we specifically seek comment.
172. First, we seek comment on the treatment of existing customers
taking long-term firm Point-to-Point Transmission Service that are not
load-serving entities. Such customers currently pay an embedded cost
charge in order to receive firm Point-to-Point Transmission Service
under the Order No. 888 pro forma tariff. We believe that it would be
inequitable for customers to receive an initial allocation of
Congestion Revenue Rights unless they also pay a share of transmission
embedded costs. We also believe that it would be inequitable for
customers to pay a share of transmission embedded costs without
receiving an initial allocation of Congestion Revenue Rights. Thus, we
seek comment on two options. One option is for these customers to
continue paying their embedded cost charges in exchange for receiving
Congestion Revenue Rights that reflect their current levels of Point-
to-Point Transmission Service. This option would help minimize cost
shifts, while maintaining the transmission rights currently held by
these customers. On the other hand, this option would recover a portion
of embedded transmission costs from customers that are not loads. The
second option is to eliminate the access charges for these customers
while also allocating no Congestion Revenue Rights to them. This option
avoids recovering embedded costs from entities that are not loads.
However, it would result in some shifting of the responsibility for
recovering embedded costs, and it would fail to maintain the
transmission rights currently held by these customers. We seek comment
on the merits of these two options, as well as whether the Final Rule
should select one option or, alternatively, allow customers to choose
between them.\106\
---------------------------------------------------------------------------
\106\ We propose that Congestion Revenue Rights be directly
assigned only to long-term firm customers, consistent with the
existing pro forma tariff's right of first refusal. Thus, short-term
and non-firm point-to-point customers would not receive Congestion
Revenue Rights under direct assignment. These customers, therefore,
may wish to structure their contracts such that they expire at the
time Standard Market Design is implemented. This way, while they
would not receive Congestion Revenue Rights, they also would no
longer be paying an access charge.
---------------------------------------------------------------------------
[[Page 55477]]
173. The second issue concerns the treatment of load-serving
entities in retail open access states that attract loads away from
their traditional utility suppliers. Under our proposal, a new load-
serving entity that attracts load from other suppliers would be
assigned a share of embedded costs--costs previously assigned to other
suppliers. In areas where there is no Available Transfer Capability for
additional Congestion Revenue Rights, we seek comment on how such new
load-serving entities should receive an allocation of the customer's
former load-serving entity's Congestion Revenue Rights. We propose that
Congestion Revenue Rights ``follow the load.'' Thus, Congestion Revenue
Rights previously allocated to other suppliers whose loads (and access
charges) have been reduced would be reallocated to the new load-serving
entities.
174. We propose to permit the use of license plate rates such as
those that are currently in effect within ISOs. We seek comment,
however, on whether we should retain license plate ratemaking only for
a transitional period and at some later date, require that all regions
have postage stamp rates. Should the Commission upon the recommendation
of a Regional State Advisory Committee accept an embedded cost recovery
mechanism for the region which may vary from neighboring regions?
175. To better illustrate the pricing proposals we have included
Appendix F which identifies by customer types whether and under what
circumstances they will pay the access charge and/or receive Congestion
Revenue Rights under Network Access Service.
2. Rates for Bundled Retail Customers
176. When a vertically integrated utility joins a regional
organization such as an ISO or RTO, the Commission has required that
the utility execute a service agreement under the regional transmission
provider's transmission tariff. For instance, the Commission required
the vertically integrated utilities in GridSouth to execute a service
agreement under the GridSouth transmission tariff, thus ensuring that
these utilities would take service for their bundled retail load under
the same terms and conditions as all other users of the grid.
177. With respect to whether the GridSouth transmission charge
should be applied to the bundled retail load, the Commission permitted
the utilities to pay the transmission portion of the bundled retail
rate, but required that the service agreement explicitly state the rate
to be charged.\107\ The Commission added that having vertically
integrated utilities pay GridSouth for transmission to serve their
bundled retail customers does not make those utilities' retail rates
subject to our jurisdiction. Rather, the Commission stated its
willingness to accommodate the utilities paying GridSouth a
transmission rate equal to the transmission component of their bundled
retail rates, as long as the price is clearly stated, reduced to
writing in contracts with GridSouth, and is not accomplished by
omission.\108\

\108\ 95 FERC [para]61,282 at 61,991.
---------------------------------------------------------------------------
178. Now that the Commission is asserting jurisdiction over all
transmission service in interstate commerce, including that for bundled
retail service, the question arises as to whether different charges for
transmission service for wholesale and bundled retail customers should
be permitted. Allowing different rates for wholesale and bundled retail
customers could lead to undue discrimination if the rate setting
policies of the state and the Commission differ significantly. The
Commission seeks comment on whether all customers should be charged the
same transmission rate either upon implementation of Standard Market
Design or after a reasonable transition period of four years.
3. Inter-Regional Transfers
179. Under current rate designs, a user that transmits power from
one region to another would pay two transmission charges to recover the
embedded costs of the transmission provider from which power was
exported as well as the embedded costs of the transmission provider
where power is delivered to load. As long as transmission owners have
an opportunity to recover their embedded costs, to increase
competition, we propose to prevent customers from being assessed
multiple transmission charges.
180. We have concluded that rate treatment for inter- and intra-
regional transactions should be consistent to avoid creating artificial
incentives or disincentives for trade across regions. Thus, the design
of rates for Network Access Service should eliminate the payment of
multiple access charges, such that only one access charge is paid for
power to reach load. Accordingly, an export and through-and-out
transaction originating in an Independent Transmission Provider's
system and terminating at a load in another Independent Transmission
Provider's system would pay only the access charge for the transmission
system where power is ultimately delivered to load.\109\ This will
encourage broader areas of competition by eliminating multiple access
charges, and in particular would reduce the harsh inequities of
regional boundary definition on those customers near such boundaries.
---------------------------------------------------------------------------
\109\ However, the transaction would still be responsible for
applicable congestion charges and transmission losses in the
originating and any intermediate transmission systems.
---------------------------------------------------------------------------
181. It has become apparent that transmission pricing across RTO
borders can have a significant impact both on power purchasing
decisions and on RTO formation. A customer's choice as to whether to
purchase power from a generator located within the same RTO or a
neighboring RTO is directly affected by the fact that one generator
faces an additional access charge to reach the RTO in which the load is
located. This additional access charge may cause the sale to become
uneconomic.\110\
---------------------------------------------------------------------------
\101\ E.g., a load and Generator 1 with a cost of $25 are
located in RTO A, and a competing Generator 2 with a cost of $24 is
located just across the border in RTO B. On its face (and absent
congestion), it appears that the load should choose Generator 2 in
RTO B. However, because Generator 2 faces a $2 transmission charge
from RTO B, it is unable to compete with Generator 1 even though it
is a more efficient unit simply because of the additional access
charge.
---------------------------------------------------------------------------
182. In addition, decisions on which RTO/ISO to join may be
affected by inter-regional pricing. Choices driven by the economics of
transmission owner's merchant function's trading patterns, rather than
by the most rational and efficient aggregation of transmission assets
for a particular region, could result in oddly configured RTOs.
183. Rate pancaking across the numerous transmission owning
utilities that comprise the RTO has been eliminated by the
implementation of license plate rates, while continuing to provide an
opportunity for the transmission owners to recover their full revenue
requirements. We propose that the same or a similar rate structure
should be applied to inter-regional transfers. In a competitive market
environment, reliability and the supplier's cost of generation, rather
than sunk transmission costs, should be the primary drivers for a
customer's choice of power suppliers. To the extent rate design
facilitates that result, transmission owners would have a greater
incentive to join an RTO based on where their transmission facilities
most benefit customers and markets, not on where their generators have
better opportunities to make off-system sales
[[Page 55478]]
(i.e., an access charge for exporting power from one region to a
neighboring region should not be the deciding factor).
184. However, absent other adjustment mechanisms, if customers
going through and out of an RTO are no longer charged access fees by
that RTO for transmission service, these costs would instead be borne
by the load served by the RTO through the existing load ratio share
methodology.\111\ Under the commonly used license plate rate design,
load within a particular RTO zone would pay that transmission owner's
full embedded costs, including the portion that is currently
contributed by through-and-out customers. This may create problematic
cost shifts for certain transmission providers that currently receive a
significant amount of revenue from exports and wheel-throughs (e.g.,
AEP and Cinergy). While simply eliminating the transmission charge for
through-and-out service may avoid the skewing of purchase and sale
decisions by inter-regional transaction charges, it will result in
cost-shifting and may stifle new transmission investment since state
regulators will not generally favor having their customers pay for
facilities that may primarily benefit other states.
---------------------------------------------------------------------------
\111\ This would also be true for a non-RTO Independent
Transmission Provider.
---------------------------------------------------------------------------
185. Therefore, we propose to create a mechanism that recognizes
the import/export quantities in establishing the revenue requirement to
be recovered through the access charge. We seek comment on two
approaches that could be used.
186. One method would be to have the ``source'' Independent
Transmission Provider allocate a portion of its revenue requirement to
the ``sink'' Independent Transmission Provider's transmission
customers. An Independent Transmission Provider's revenue requirement
could be reduced by the amount of revenues associated with through-and-
out service and that portion of the revenue requirement would then be
included as uplift in the scheduling charge paid by all customers of
the sink Independent Transmission Provider in whose service area the
power sinks. Under this approach, costs would not be shifted from the
beneficiaries of the inter-regional transaction to the load on the
source side of the transaction. At the same time, embedded cost
recovery would not interfere with short-run efficiency, since embedded
costs would not be recovered in individual inter-regional transactions,
but would instead be recovered through uplift from all customers in the
zone of the sink Independent Transmission Provider. This method would
require a projection of inter-regional transfers and a rate filing to
accomplish the re-allocation of costs between Independent Transmission
Providers. It would also require a decision as to how narrowly to focus
the cost allocation (e.g., RTO to RTO, export zone to import zone).
187. Alternatively, under a revenue crediting approach, inter-
regional transfers could be priced at the load ratio share charge (or a
similar transmission charge)\112\ and the inter-regional transaction
charges would be netted out over some time period (e.g., one month or
one year). This method would assign the inter-regional charges to all
customers within the sink Independent Transmission Provider. The cost
of transmission on a neighboring Independent Transmission Provider
associated with net imported power could be charged to all of the net
importing Independent Transmission Provider's customers through the
Independent Transmission Provider's scheduling charge. The revenues
would be returned to all transmission customers within the net
exporting Independent Transmission Provider.
---------------------------------------------------------------------------
\112\ An explanation of how this charge may be calculated is
contained in Appendix F.
---------------------------------------------------------------------------
188. We seek comment on whether there should be a uniform cost
allocation of inter-regional costs among all zones within an
Independent Transmission Provider's system. For instance, there will
likely be opposition to a region-wide charge by customers who do not
import power. To address this concern, the inter-regional transfers
could instead be netted out between zones within neighboring
Independent Transmission Providers. This way the costs would be
assigned to all customers within the import zone and the revenues would
be returned to the export zone. These transmission costs could be
assigned to the zone where the power was imported as if the neighboring
Independent Transmission Provider's facilities were part of that zone.
Likewise, the zone where exports leave an Independent Transmission
Provider would receive the transmission payments associated with the
exports. It is possible that the revenue sharing plan used by ISOs with
license plate rates to resolve intra-ISO, interzone transactions could
be broadened to encompass inter-RTO transactions.
189. As noted above, the proposed rule advocates treating inter-
and intra-regional transmission pricing the same. As explained
elsewhere, customers within the region who pay the access charge will
be entitled to Congestion Revenue Rights or the revenues from the
auction of those rights. We propose a similar result for inter-regional
transactions when customers in one region are paying a portion of the
embedded costs of another region. We seek comment on how to assign
Congestion Revenue Rights to the customers of the importing region. For
example, if Midwest ISO is a net exporter to PJM, customers on PJM's
system will be obligated to pay a portion of Midwest ISO's embedded
costs. PJM's customers could receive a proportionate share of Midwest
ISO's Congestion Revenue Rights.
4. Application of Inter-Regional Pricing to Parallel Path Flows
190. To the extent the Commission adopts a true-up methodology for
recovering the costs of through-and-out services, should a similar
pricing methodology be applied to parallel path flows? Parallel path
flows are comparable in that one region benefits by the use of a
neighboring region's transmission facilities. Parallel path flows are
currently resolved through cooperation. An alternative method would be
to price all uses of the grid. We seek comment as to how cost impacts
of parallel path flows across regional borders should be addressed.
5. Pricing of New Transmission Capacity
191. The existing transmission grid has fallen far behind the
demands that have been placed on it. Over the last ten years, we have
seen a strong increase in the amount of new generation, which has been
built largely in locations that make the most economic sense for the
builder of the generation (i.e., where land is affordable and economic
sources of fuel, water and labor are near). However, we have yet to see
a parallel jump in construction of transmission infrastructure. The
absence of needed new transmission facilities has led to more and more
congestion, which hinders customers from seeking and depending on more
distant and competitive supply choices.
192. The sluggishness of transmission construction is largely
because: (1) Siting transmission is a long and contentious process; and
(2) mismatches between those who benefit from the new facilities and
those who pay for them, particularly when the two affected sets of
customers are served by different transmission providers, are often
more than enough to make sure the new facilities do not get built. The
Department of Energy's 2002 National Transmission Study points to
state-by-state siting approval, a lack of regional
[[Page 55479]]
institutions and a lack of clarity in regulatory pricing policy as
several of the barriers to transmission investment.\113\
---------------------------------------------------------------------------
\113\ See DOE National Transmission Grid Study.
---------------------------------------------------------------------------
193. The Commission's pricing policy for network upgrades, whether
for reliability or economic reasons, has traditionally favored ``rolled
in'' pricing, where all users pay an administratively determined share
of new facilities. This policy was based on the rationale that the
transmission grid is a single piece of equipment such that system
expansions are used by and benefit all users due to the integrated
nature of the grid. This method forms the basis of the pricing proposal
in the Generation Interconnection proposed rule.
194. If the expansion is for region-wide reliability, there is
little disagreement as to who should pay for the necessary facilities--
all ratepayers. Likewise, interconnection facilities are non-
controversial; there is general agreement that these facilities should
be directly assigned to the interconnecting generator.
195. What we see, however, is that economic expansions that would
remove congestion and allow customers to reach more distant power
supplies are the most difficult to get sited. This is at least in part
because state siting authorities have no interest in siting a line that
benefits a particular generator or a distant load in another state
because to do so would require the load on the constructing public
utility's system to pay for the new facilities. The state authorities,
at a minimum, need assurance that the costs of that expansion will be
paid for by those who benefit from the expansion in order to have
sufficient incentive to site the new facilities.
196. Our goal is to remove any cost recovery impediments to
transmission expansion so that needed upgrades get built now.
Traditional means of expansion pricing may not be the most effective
way of encouraging new transmission infrastructure, in part perhaps
because they do not take into account the wide regional benefits of
higher voltage upgrades that can accrue beyond a single transmission
owner's system.
197. We believe that a more precise matching of beneficiaries and
cost recovery responsibility would encourage greater regional
cooperation to get needed facilities sited and built. Our preference is
to allow recovery of the costs of expansion through participant
funding, i.e., those who benefit from a particular project (such as a
generator building to export power or load building to reduce
congestion) pay for it.
198. The Generator Interconnection proposed rule introduced the
idea that participant funding may be an acceptable pricing policy where
an independent entity determines: (1) The cost of and responsibility
for needed upgrades; (2) congestion price signals to which the customer
responds (along with Congestion Revenue Rights); and (3) the
assumptions underlying the power flow analysis.\114\
---------------------------------------------------------------------------
\114\ The Commission is currently reviewing extensive comments
on this topic in that proceeding.
---------------------------------------------------------------------------
199. The Commission envisions that, under Standard Market Design,
the Independent Transmission Provider will perform all of these
functions, which will allow the Commission to consider the use of
participant funding. However, full compliance with Standard Market
Design will take some time. We are eager to see new infrastructure in
place as soon as possible and believe that participant funding will be
a useful tool to make that happen. Accordingly, we propose that, for
proposed transmission facilities that are included in a regional
planning process which is conducted by an entity, whether an RTO, ISO,
or other independent entity, that is independent, we will consider
participant funding for that project.
200. In the absence of independence, we would apply a default
pricing policy that would recognize the regional benefits of
transmission expansions. Under this default policy, we propose to roll-
in on a region-wide basis all high voltage network upgrades of 138 kV
and above. Since lower voltage, sub-regional transmission needs are
less likely to benefit the whole region, the cost of network facilities
below 138 kV could be more appropriately allocated to a sub-region
(e.g., a single transmission owner or a ``license plate'' zone) where
the expansion facilities will be located. Consistent with our proposal
for interregional transmission service pricing, costs would be
allocated to the region that benefits from the expansion, which may not
be the same as the region in which the expansion facilities are
located. This proposal recognizes that high voltage expansions can have
benefits beyond the borders of the local transmitting utility and,
therefore, assigns a portion of these costs to more distant
beneficiaries.
201. Further, as we explain in Section IV.G.3, Regional Planning
Process, we encourage the formation of Regional State Advisory
Committees, which, in addition to facilitating the siting of regional
expansions, can enable states to work together to identify
beneficiaries of expansion projects and make recommendations on pricing
proposals. To the extent there is agreement within the Regional State
Advisory Committee, the Commission would look favorably on a pricing
proposal by the Regional State Advisory Committee if it is consistent
with the FPA. Such a proposal might take the form of roll-in, an
assignment to beneficiaries, or some combination of the two.
202. We seek comment whether these pricing proposals are
appropriate to meet our goal of expediting needed infrastructure
investment or whether another method would be more effective.
E. The New Congestion Management System
203. Under Network Access Service, all transmission customers may
request transmission service. The Independent Transmission Provider
must honor all valid transmission requests where there is sufficient
capability, i.e., when there is no transmission congestion. However,
when there is transmission congestion we propose to require that all
Independent Transmission Providers allocate scarce transmission
capability using a price system. Specifically, we propose to require
that all Independent Transmission Providers manage congestion using a
system of LMP and Congestion Revenue Rights. Under LMP, the price to
transmit energy between any receipt point and delivery point reflects
the marginal cost (including the marginal opportunity cost) of such
transmission service, and the price of energy at each location reflects
the marginal cost (as reflected in participants' bids) of producing
energy and delivering it to that location.
1. Locational Marginal Pricing
204. LMP is the method that is currently used for managing
congestion in the regional markets run by both PJM and New York ISO. It
is also proposed to be adopted as the congestion management system for
ISO-New England in 2003 and for the California ISO in its proposed
market redesign.\115\ Marginal pricing, a fundamental concept in
economics, is the basis for LMP.\116\ Marginal pricing is the idea
[[Page 55480]]
that the market price should be the cost of bringing the last unit to
market (the one that balances supply and demand). LMP in electricity
recognizes that the marginal price may differ at different locations
and times. Differences result from transmission congestion which limits
the transfer of electricity between the different locations.\117\ The
marginal price of energy at a particular location and time--that is,
the energy LMP--is the additional cost of procuring the last unit of
energy supply that buyers and sellers at that location willingly agree
on to meet the demand for energy. That is, it is the price that
``clears the market'' for energy.\118\
---------------------------------------------------------------------------
\115\ See California ISO's Comprehensive Market Design Proposal,
Docket No. ER02-1656-000 (May 1, 2002); see also California
Independent System Operator Corp., 100 FERC [para]
61,060 (2002).
\116\ It is a widely accepted principle of economics that
markets work efficiently when prices reflect marginal costs. See
Alfred E. Kahn, The Economics of Regulation: Principles and
Institutions, The MIT Press, Cambridge, Massachusetts, reprinted
1988, pp. 63-70. The economic rationale for applying marginal cost
pricing to an electricity network using the concepts of LMP was
presented in Schweppe, F.C., et al., Spot Pricing of Electricity,
1988, Norwell, MA, Kluwer Academic Publishers; and Hogan, William
W., ``Contract Networks for Electric Power Transmission,'' Journal
of Regulatory Economics, 1992, vol. 4, pp. 211-242.
\117\ Prices may also vary based on transmission losses. For
purposes of simplification this discussion focuses on the
differences due to energy prices alone.
\118\ Under LMP, all suppliers selling at a location receive the
market clearing price, including those who offer in their bids to
sell for less. Similarly, all buyers purchasing at the location pay
the market clearing price, including those who offer in their bids
to purchase at a higher price. An alternative policy would be to pay
each seller its bid price (and perhaps, to charge each buyer its bid
price). We propose a single market clearing price for several
reasons. First, it encourages sellers to submit bids that reflect
their marginal costs (and thus, the sellers selected in the energy
auction are more likely to be the sellers with the lowest actual
costs). Sellers without market power could not increase the market
price by increasing their bids, so bidding above their marginal
costs would have no benefit to them. Bidding above marginal cost
would merely create the risk that the seller would lose in the
auction when the market price was higher than the seller's marginal
costs, and thus, the seller could have earned a profit. Moreover, by
paying all sellers the market clearing price, sellers with marginal
costs below the market clearing price would receive revenues to help
recover their fixed costs. A policy of paying each seller its bid
would encourage sellers to bid above their marginal costs, since
doing so would be the only way for them to earn a profit. As a
result, the sellers selected in the auction would not necessarily be
the sellers with the lowest actual costs. Moreover, if the pay-as-
bid policy were applied only to sellers (and not to buyers), so that
buyers were charged the average payment made to sellers, buyers
would face a price that was lower than the highest accepted seller's
bid. This result would encourage inefficient purchases and poor
demand response. For example, on a hot day when the highest accepted
seller's bid is $1000/MWh but the average payment to sellers is
$400/MWh, charging buyers $400/MWh under pay-as-bid would encourage
less demand response than a market clearing price policy of charging
$1000/MWh. If the pay-as-bid policy were applied to both sellers and
buyers, then the revenue collected from buyers would usually differ
from the revenue paid to sellers.
---------------------------------------------------------------------------
205. LMP is a market-based method for congestion management.
Congestion is managed through energy prices and transmission usage
charges (congestion and loss charges) determined in a bid-based market.
When there is no congestion anywhere on the system (when there is
enough transmission capacity to get power from the cheapest available
generators to all potential buyers) there will be only one energy price
in the transmission system, the price bid by the last, or marginal,
generator that provides energy or load that offers to reduce its
demand.\119\ When there is congestion, the cheapest generators may be
unable to reach all their potential buyers. Consequently, when there is
congestion there may be many different energy prices across the
transmission system.\120\ Under LMP, the Independent Transmission
Provider will establish separate energy prices at each node on the
transmission grid and separate prices to transmit energy between any
two nodes (receipt and delivery points) on the grid. These prices
reflect the cost of congestion. LMP relies on economic redispatch in
managing congestion. Redispatching means decreasing the energy the
Independent Transmission Provider obtains in front of the constraint
(where the power is flowing from) and increasing the energy the
Independent Transmission Provider obtains behind the constraint (where
the power is flowing to). The cost of redispatch is the basis for the
congestion charges under LMP. If a customer is willing to pay the
marginal cost of redispatch, which it signals through its bids, the
Independent Transmission Provider will schedule the transmission
service.
---------------------------------------------------------------------------
\119\ The operation of the bid-based auction for energy is
described further in Section IV.
\120\ Because the transmission grid is a network, reducing
transmission service between one receipt point--delivery point pair
(e.g., from A to B) may free up transmission capability for
transmission service between a different receipt point--delivery
point pair (e.g., from C to D), albeit not necessarily on a MW-for-
MW basis. For example, reducing service from A to B by 2 MW may
allow an additional 1 MW of transmission service from C to D. If so,
the price to transmit 1 MWh of energy from C to D must reflect at
least what a customer denied 2 MW of service from A to B would have
been willing to pay.
---------------------------------------------------------------------------
206. For example, assume there is congestion or a constraint on one
transmission interface. Some low-cost generators may not be able to
deliver energy to load on the other (import) side of the constraint.
So, they will need to reduce their production because of the
constraint. To signal these generators to reduce their production, the
energy price that these generators would receive would be lowered. To
replace the low-cost generation, more expensive generators on the other
side of the constraint (export) must be dispatched. To signal to these
higher cost generators that they should increase their production, the
energy price they would receive would increase. As a result the energy
price on each side of the transmission constraint would be different.
The energy price would be lower on the side where more suppliers are
trying to sell out of the region than can be accommodated by the
transmission capacity. The energy price would be higher on the side
where more expensive local generation must be used because of the
transmission constraint. As discussed further in Section IV.F., for
purchasers of energy in the Independent Transmission Provider-run spot
markets, the LMP at the node closest to them is their delivered power
cost (energy charge plus transmission charge). The generators are then
paid the LMP at the nodes closest to them.
207. For customers buying energy through bilateral contracts rather
than in spot markets, the transmission usage charge would reflect the
marginal cost of transmission between a receipt point and a delivery
point.\121\ In the above example, the difference would be the marginal
cost of moving energy from the import to the export side of the
constraint which should equal the difference in the energy price on the
import and the export side of the constraint. In other words, the
transmission usage charge for bilateral transactions would be the
difference between the LMP at the receipt point and the delivery point.
When congestion exists, the difference in energy prices to transmission
users is a price signal that reflects the marginal cost of economic
dispatch of resources necessary to accommodate the transmission
service. Those who place a higher value on the transmission capacity
and the value of the ultimate delivered electricity, will be willing to
pay higher transmission usage charges. Also, because transmission usage
charges for bilateral transactions are based on the differences in spot
market energy prices, the proposed congestion management system would
not bias a customer's choice between purchasing energy through the spot
market versus a bilateral transaction.
---------------------------------------------------------------------------
\121\ Transmission losses will also be recovered through the
transmission usage charge and included in the energy prices under
LMP.
---------------------------------------------------------------------------
208. LMP uses a financial instrument called a Congestion Revenue
Right to provide customers with price certainty for transmission
service.\122\ A Congestion Revenue Right is a financial tool that
allows a customer to protect itself against the costs of congestion. A
Congestion Revenue Right ensures that the holder of that right will be
protected
[[Page 55481]]
against congestion costs for the transmission service covered by that
right in the day-ahead market.\123\ Once the day-ahead market closes,
all customers pay for the service requested and, if they hold
Congestion Revenue Rights, are paid congestion costs associated with
those rights. Thus, the customer has bought and paid for a quantity of
transmission at a specified price.
---------------------------------------------------------------------------
\122\ As discussed above, we also propose that Congestion
Revenue Rights would provide a scheduling priority in certain
circumstances.
\123\ For example, a customer holding Congestion Revenue Rights
could be charged the congestion costs (e.g., $10 MWh) and then
receive a credit on the same bill for congestion revenues (e.g., $10
MWh). So, the net congestion costs paid by the customer is $0. The
customer, however, would have to pay for transmission losses.
---------------------------------------------------------------------------
209. Any changes a customer wants to make to the transmission
service it has scheduled in the day-ahead market must be accomplished
in the real-time market at real-time prices, which may be different
from the day-ahead prices. A customer wanting less transmission service
than it requested and received in the day-ahead market would
effectively sell back to the market the amount of unused service.
Conversely, a customer needing an additional amount of transmission
service could buy the additional amount of service in the real-time
market. No congestion revenues are paid to Congestion Revenue Rights
holders for transactions made in real-time market.\124\
---------------------------------------------------------------------------
\124\ For example, a customer schedules and receives 100 MW of
transmission service the day ahead at a congestion cost of $2/MW.
The customer pays the $2/MW of congestion charges to the Congestion
Revenue Rights holder (which could be itself). The customer may
later decide it only needs 90 MW. It could then sell in the real-
time market the unneeded 10 MW. If congestion in the real-time
market is $3, the seller would receive $3/MW (or $30) for the sale
of the 10 MW of transmission service from the buyer of the
transmission service.
---------------------------------------------------------------------------
210. The LMP system for congestion management is better suited to
manage congestion in a competitive market than the congestion
management system under the Order No. 888 pro forma tariff (pro rata
curtailment) because LMP allocates scarce transmission capacity to
those who value it most and it relies on an incentive system (i.e., it
assigns congestion costs to the transactions that cause the congestion)
that encourages market participants to buy and sell power in a manner
that is consistent with the reliable operation of the system. Under an
LMP system, market participants have greater commercial flexibility in
arranging transactions. Market participants have the ability to signal
whether they are willing to buy their way through transmission
constraints. Under the current system they do not have the ability to
do that, in part because transmission providers do not have a mechanism
for recovering the cost of economic redispatch. Currently, these types
of transactions would not be scheduled because of the existence of
congestion. Also, Network Access Service customers would have the
ability to voluntarily resell their Congestion Revenue Rights when
others value them more highly. Because market participants will see and
be responsible for the full effect of their decisions on congestion
costs, each have an incentive to manage its own transactions in a way
that is consistent with a least-cost dispatch consistent with reliable
system operations.
211. The proposed SMD Tariff lays out the general framework and the
basic rules for LMP. It is based on the best practices we have seen. We
recognize that in certain regions there may need to be additional rules
or changes to accommodate specific regional requirements. We also
recognize that over time there likely will be a need to update the
tariff provisions to offer new service options or to further refine the
market rules. The pro forma tariff is not intended to be a static
document, but rather one that will evolve over time and meet the needs
of the marketplace. We seek comment on how best to recognize this need
for regional variation and the need for continued refinement in the
rules.
212. One concern that has been expressed in the Standard Market
Design conferences and in comments on the Working Paper is that while
LMP may work well with systems that are dominated by thermal plants, it
may not work in systems that primarily rely on hydroelectric resources.
In particular, the Pacific Northwest is concerned that an hourly bid-
based system with LMP may be in conflict with Northwest resource uses,
practices and obligations, which are dominated by hydroelectric
generation. Much of this is from ``run-of-river''\125\ facilities that
cannot store water, and at which energy is lost if a generator does not
run when water is available. Because the decision to run is virtually
automatic, many Northwest parties see no need for a bidding system.
Also, many of the hydroelectric facilities of the Columbia River System
must coordinate their operations; whether a downstream facility runs
depends on whether an upstream dam runs and releases water. Some of
this coordination is among facilities in the United States and Canada
and is subject to international treaties. There is a concern that a
bid-based system with LMP, which requires individual generators to bid
independently against one another, ignores this cooperation or even
would view such cooperation as collusion in a market system. Some
coordination agreements assure that low-cost transmission will be made
available to implement the coordination, and there is a concern that
LMP congestion pricing may be incompatible with these agreements.
---------------------------------------------------------------------------
\125\ Run-of-river facilities use the natural flow of the river
to generate electricity. They typically divert water from a nautral
channel, run the water through a turbine to produce energy and then
return the water to the natural channel downstream of the turbine.
---------------------------------------------------------------------------
213. Northwest parties note that while annual costs in a thermal
system are minimized simply by minimizing the costs in every individual
hour the same does not hold true in a hydropower system. A
hydroelectric dam with stored water has a marginal running cost close
to zero, however, this does not mean that it should be dispatched first
every hour. Rather, the value of hydropower over time depends on when
that stored energy system can best be released to minimize costs over a
season, a year, or even a multi-year period. Thus, there is a concern
that in a hydropower system, a congestion management and energy spot
market designed to minimize hourly costs will not minimize costs over a
longer period.
214. Moreover, commenters have noted that decisions about water use
in the Northwest are based on more than electric power cost
minimization. Decisions about use of hydropower facilities involve
coordinated trade-offs among power needs, the needs of fish and
wildlife, irrigation, flood control, recreation and other factors,
which may be difficult to reflect in the bids of individual units. Some
parties in the Northwest acknowledge that a bid-based LMP system could
be adapted to meet the objections above but are concerned either that
such a system may be imposed without adaptation or that the adaption
will be done poorly. There is also concern that adaptation to a bid-
based security-constrained system may reopen such issues as
transmission priorities and preference power allocations that have been
settled over many years of negotiation based on factors other than
market efficiency. Finally, Northwest parties worry about obtaining
sufficient Congestion Revenue Rights to protect against congestion
charges.
215. We believe that the proposed Standard Market Design would work
well in every region and for all types of fuel sources; we believe that
the concerns expressed by participants in the Pacific Northwest can be
accommodated within the LMP system we propose. First, use of the
Independent Transmission Provider's bid-based spot energy markets would
be
[[Page 55482]]
optional. No one would be required to bid into these markets (except
when market power mitigation is imposed).\126\ Hydropower generators
could choose to self-schedule without submitting a price bid. As a
result, the bilateral contractual energy arrangements of the Northwest
would be unaffected. Thus, for example, hydropower facilities along a
common waterway that wish to develop a coordinated schedule without
submitting energy price bids would be free to do so. Also, hydropower
facilities that must consider non-price factors such as the needs for
irrigation, flood control, and fish and wildlife in their scheduling
decisions could do so through the self-scheduling feature.
---------------------------------------------------------------------------
\126\ The market power mitigation measures would be developed on
a regional basis and would take into account the special
characteristics of hydropower.
---------------------------------------------------------------------------
216. For hydropower generators that wish to participate in the
Independent Transmission Provider's spot energy markets, the Standard
Market Design that we propose can accommodate the special features of
hydropower facilities. Suppliers would be allowed to reflect their
opportunity costs in their bids; bids need not be limited to marginal
running costs. Also, generators such as hydropower facilities would
have the option (but not the requirement) of requesting the Independent
Transmission Provider to schedule the generator's designated MWhs over
the highest priced hours of the day, to economically optimize
hydropower production over the day. LMP is a result of a least-cost
dispatch of the resources available to the transmission system in a
manner that recognizes both the operational limits of those resources
and the operational limitations of the transmission system. As a
result, customers' loads can be met at the lowest total cost (as
reflected in the submitted bids) consistent with the reliable operation
of the system, which should be the objective on any system regardless
of the resource base of the transmission system.
217. In short, we see no reason why the proposed Standard Market
Design would prevent hydropower generators from operating in a way that
accommodates their special features. Indeed, we believe that the LMP
system would aid hydropower generators in optimizing the economic value
of their resources within their legitimate operational constraints,
because the prices for energy and transmission would signal the
economic costs of providing energy and transmission service at
different locations and time periods.
218. Finally, our proposal here would not abrogate existing pre-
Order No. 888 transmission contracts, so customers holding these rights
could continue their existing services under the existing contractual
provisions. In addition, this proposal would allocate Congestion
Revenue Rights or auction revenues to parties based on their recent
historical usage of transmission. Thus, customers receiving
transmission service under the Order No. 888 pro forma tariff, as well
as entities previously serving bundled retail load outside the pro
forma tariff, would receive Congestion Revenue Rights to protect
against congestion charges.
219. We agree that the operational limits of both the resources and
the transmission systems need to be fully considered in the design of
the specific market rules. For example, there is likely a need to
calculate opportunity costs for hydroelectric resources differently
from thermal plants. These differences can affect market mitigation
measures. However, we are concerned about whether different market
designs can be in place in the Northwest and the rest of the West, and
ask for comment on whether the entire West must have a common set of
market rules to eliminate seams and prevent manipulation.
220. In the SMD Tariff we propose to include several different
types of Congestion Revenue Rights to allow customers to protect
against congestion costs. For example, one concern that we have heard
from customers and suppliers in the Northwest is that a receipt point-
to-delivery point Congestion Revenue Right may not work to effectively
manage congestion on a system that utilizes several different
hydroelectric facilities on a contingent basis to serve the same
delivery points. A Congestion Revenue Right that recognized the
contingent nature of the supply sources would be more valuable to
customers in this instance. We believe that developing these types of
Congestion Revenue Rights is possible and we propose to work with the
regions to develop variations to meet regional needs. The congestion
management system that we propose is flexible enough to accommodate
these types of regional variations. Such variation and flexibility
should not impinge on the development of a seamless electric grid.
2. LMP and Energy Markets
221. To implement LMP, the Independent Transmission Provider must
operate an energy market to determine the marginal cost of redispatch.
We propose to require that the Independent Transmission Provider
operate both a day-ahead and a real-time energy market to manage
congestion.
222. The Commission proposes to use real-time markets for energy to
resolve energy imbalances. Under the proposal, the transmission
customer would be charged the real-time price of energy for any
imbalance, i.e., the difference between the energy the transmission
customer schedules a day ahead on the system and the amount that it
takes off the system in real time. The real-time price of energy is
determined through a security-constrained, bid-based energy market run
by the Independent Transmission Provider. The Independent Transmission
Provider uses the bids to select the lowest-cost energy within the
operational limitations of the transmission system. These same
procedures will be used to resolve imbalances for all users of the
transmission system.
223. The Commission also proposes that the Independent Transmission
Provider operate a security-constrained, financially binding day-ahead
energy market that is operated together with a day-ahead scheduling
process for transmission service.\127\ The day-ahead market for energy
will allow the Independent Transmission Provider to manage congestion
that arises in the day-ahead scheduling process.\128\
---------------------------------------------------------------------------
\127\ The operation of both a financially binding day-ahead
market in conjunction with a financially binding real-time market is
also known as a multi-settlement system.
\128\ Such markets are currently operated by the New York ISO
and PJM. California ISO and ISO-New England are planning on adding
this feature to their market design.
---------------------------------------------------------------------------
224. The day-ahead energy market is a bid-based market. Sellers
submit bids that indicate the quantities of power they will offer for
sale in each hour of the next day and the price for that power at each
location (node).\129\ The price for the power may vary based on the
quantities that are offered for sale. The differences in bid prices
recognize that a generator's marginal cost of producing power can vary
at different quantity levels because it operates more efficiently at
certain output levels than others. Also, at the highest output levels,
there may be additional opportunity costs because of an increased risk
of a unit outage. Buyers also submit bids indicating the quantities
they desire to purchase in each hour of the day. Buyers may also
[[Page 55483]]
indicate the maximum price they are willing to pay for those
quantities.
---------------------------------------------------------------------------
\129\ The bids usually take the form of a bid curve that shows
the bid price and quantity between the unit's minimum output and its
maximum output. Usually the prices are relatively flat over the
normal operating range of the unit. As quantities approach the
maximum output the prices usually increase very rapidly.
---------------------------------------------------------------------------
225. Under the Commission's proposal, buyers are not required to
procure energy through the day-ahead energy market. A load-serving
entity may procure all of its power through bilateral transactions, in
the transmission provider's spot markets, or by generating its own
power.\130\ However, a load-serving entity may use the day-ahead market
if it needs to acquire additional power or the price of power through
the day-ahead energy market is lower than the price of power under an
existing bilateral contract or the cost of generating its own power. A
generator may also buy power through the day-ahead market. It would do
this if it could buy the power more cheaply than generating to satisfy
a bilateral contract obligation or if a forced outage requires it to
procure power to satisfy a contract obligation.
---------------------------------------------------------------------------
\130\ These transactions must still be scheduled through the
day-ahead market and are subject to congestion costs if they do not
have Congestion Revenue Rights.
---------------------------------------------------------------------------
226. The Commission proposes to require Independent Transmission
Providers to allow buyers and sellers to submit purely financial bids,
a feature that currently exists in the day-ahead markets run by PJM and
New York ISO. These financial bids to buy or sell power are not backed
by actual generation resources nor are they backed by actual load.
Rather, these transactions are used to bring the prices in the day-
ahead market and in the real-time market closer together. For example,
suppose that the day-ahead price is consistently lower than the
corresponding real-time price. Entities may therefore want to submit
financial bids to buy energy in the day-ahead market at the lower
price, and submit a corresponding bid to sell in the real-time market
at the higher price, thereby making a net profit on the two
transactions. The additional buyer bids in the day-ahead market would
tend to increase day-ahead prices, while the additional supply bids in
the real-time market would tend to reduce the real-time prices. The
result is that the price differences in the two markets would shrink,
as would the profits of sale. This process benefits the market. It
helps market participants make better decisions in advance--in the day-
ahead time frame--that will affect how much electricity they will sell
or buy, because the day-ahead price becomes a more accurate gauge of
what the real-time price will be.
227. The day-ahead energy market is operated together with the
congestion management system and the day-ahead scheduling process for
transmission service. The Independent Transmission Provider will
determine market clearing prices for each hour in the day-ahead energy
market based on the sale and purchase bids that are submitted. The
market clearing price is the bid of the last unit of supply needed to
satisfy the demand, i.e., the highest bid that is accepted. The market
clearing price at a location is paid to all suppliers at that location
that are selected in the auction and is paid by all buyers at that
location that purchase through the auction.
228. We believe there are important differences between Standard
Market Design and the market design that was in effect in the
California ISO when it experienced problems in the energy markets in
2000 and 2001. First, Standard Market Design is premised on the use of
bilateral contracts. While LSEs may purchase energy in the spot
markets, these purchases should constitute a small percentage of their
actual purchases. In contrast, the California market design required
the LSEs to purchase the bulk of their energy needs through the spot
markets. Second, Standard Market Design includes a forward-looking
long-term resource adequacy requirement to avoid the types of supply
shortages that adversely affected California. Third, as discussed in
more detail in Appendix E, Standard Market Design includes trading
rules, a congestion management system, market power mitigation
measures, and market power monitoring to address the manipulation
strategies encountered in the California markets.
229. In determining market clearing prices, the Independent
Transmission Provider factors in the operational limitations of the
transmission capacity, such as congestion and reactive power needs, to
ensure that the units that set the market clearing prices are
consistent with the transmission system operations (i.e., a security-
constrained dispatch).\131\ Because LMP is used as the congestion
management system, the market clearing prices are the prices for energy
delivered to each location or node on the system. If there is no
congestion on the transmission system, the same market clearing price
for energy will apply throughout the system.
---------------------------------------------------------------------------
\131\ It is important that the schedule developed through the
day-ahead market be physically feasible, i.e., consistent with
reliable transmission limitations. If it were not, then it would be
necessary to make separate congestion payments to suppliers in real
time to change their output so that the real-time schedule was
consistent with reliable transmission limitations. This would
provide an incentive for suppliers to create congestion in the day-
ahead market so that they could receive payments in real time to
relieve congestion.
---------------------------------------------------------------------------
230. The day-ahead market would be financially binding. This means
that a seller that is selected in the day-ahead market is obligated to
actually provide the power in real time or in real time it will be
charged the cost of procuring the shortfall through the real-time
market.\132\ The day-ahead market is also financially binding on
buyers.\133\ This reduces certain opportunities for strategic bidding
and thus, market manipulation.
---------------------------------------------------------------------------
\132\ For example, assume in the day-ahead market a generator
agreed to sell 50 MW for the hour running from 9 a.m. to 10 a.m. at
a price of $30 Mwh. In the day-ahead market the generator would
receive $1,500 ($30 times 50) for that sale. In real time, the
generator only delivered 20 MW during that hour. The real-time price
of energy in that hour was $40 MWh. The generator would be charged
$1200 for its 30 MW shortfall in real time (30 times 40). Thus, the
generator would receive a total net payment of $300.
\133\ For example, assume that a load-serving entity buys 40 MW
in the day-ahead market for the hour 10 a.m. to 11 a.m. at a price
of $30 Mwh. In the day-ahead market the load-serving entity would
pay $1200 (40 times 30) for that purchase. In real time the load-
serving entity only took 35 MW in that hour. The real-time price of
energy for that hour was $25. The load-serving entity would
effectively sell back the excess power (5 MW) at the real-time price
($25), $125. Thus, the load-serving entity would pay a net total of
$1075.
---------------------------------------------------------------------------
231. Years of experience with organized markets makes it clear that
a day-ahead market is a best practice that must be included in the
Standard Market Design. The development of a day-ahead schedule for
energy and transmission service, including certain ancillary services,
provides reliability benefits. It allows the Independent Transmission
Provider to have advance warning to ensure that sufficient units are
committed to serve the projected load. For example, if the Independent
Transmission Provider believes that load has not scheduled sufficient
transmission service or energy purchases in the day-ahead markets, it
can commit additional units to be available in real time. Because of
their operating characteristics, different types of generation units
have differing levels of start-up costs as well as different lead times
to be available in real time. The day-ahead market gives the
Independent Transmission Provider information on unit availability,
costs and system needs well before real time so the Independent
Transmission Provider has more options available to ensure reliability
and reduce costs in the real-time market.
232. Finally, the day-ahead market provides an important platform
for market power mitigation. We propose several mitigation measures to
ensure that there is a well-functioning spot market for wholesale
power. These spot
[[Page 55484]]
markets will result in price transparency, so buyers and sellers can
see that market clearing prices are set in a fair and predictable
manner. While the real-time market will be a transparent market, real-
time prices may not be known until after the fact or at most five to
ten minutes before real time. This gives buyers and sellers little
chance to react to prices. In contrast, a day-ahead market provides a
transparent spot market that allows buyers and sellers to engage in
additional commercial transactions before real time. Thus, a day-ahead
market helps liquidity and is likely to be less volatile than the real-
time market.
233. The Independent Transmission Provider will also establish
hourly prices for certain ancillary services, which may differ by
location to the extent that ancillary service requirements differ by
location. Since the same supply resources can often be used to provide
either energy or ancillary services, energy and ancillary services
should have compatible market designs. Otherwise, there would be an
incentive to sell one type of product over another. Since both are
needed, a compatible system allows the supplier to sell energy or
ancillary services, whichever is the most efficient use of the supply
resources. This yields the lowest total costs to customers.
234. As explained further below, the Independent Transmission
Provider will need to manage congestion in two time frames: (1) During
the day-ahead scheduling process, and (2) during real-time operations.
The Independent Transmission Provider will conduct separate auctions to
manage congestion in each time frame. In the day-ahead auction, for
each hour of the following day the Independent Transmission Provider
will take bids to buy and sell energy, to provide certain ancillary
services, and to purchase transmission service between identified
receipt and delivery points. The Independent Transmission Provider will
consider the bids for energy, transmission service and ancillary
services simultaneously. Based on those bids, the Independent
Transmission Provider will develop a schedule that maximizes the
economic value (as reflected in the bids) of the transactions over the
entire day-ahead period, in light of the amount of Available Transfer
Capability and any resulting transmission congestion and losses. The
Independent Transmission Provider will also establish prices for
transmission service, energy and ancillary services that clear the
markets.
3. Congestion Revenue Rights
235. Under LMP, transmission usage prices will vary based on the
price of relieving transmission congestion and losses. Rather than
using a system of physical reservations, a system of financial rights
called Congestion Revenue Rights will be used to give customers the
ability to protect themselves against congestion costs.
236. The initial allocation process for Congestion Revenue Rights
will be done through compliance filings that allow for different
treatment within each region. Since this must occur before Standard
Market Design is implemented, we have not addressed initial allocation
in the SMD Tariff, but it is discussed in Section IV.E.3.e below. This
section describes allocation processes that would be used after the
initial allocation has been done.
a. General Features
237. We propose to require that Independent Transmission Providers
offer Congestion Revenue Rights of several types (one that we will
mandate now and others that should be offered upon customer request
when technically feasible) that allow transmission customers to obtain
protection against uncertain future congestion charges. We have added a
new section to the SMD Tariff that describes the types of Congestion
Revenue Rights that would be available, how one acquires Congestion
Revenue Rights after the initial allocation and how Congestion Revenue
Rights provide protection against congestion costs (Part II.D.,
Congestion Revenue Rights). The proposed provisions are discussed
below.
238. The Independent Transmission Provider would be required to
offer Congestion Revenue Rights for all of the transmission transfer
capability on the grid, but it would not be allowed to sell more rights
than can be accommodated. Congestion Revenue Rights would be available
over a variety of terms, such as weekly, monthly, yearly and perhaps
for longer terms. If an entity pays to construct new generation or
transmission facilities that add transfer capability, and the costs of
the upgrade are not rolled in, the entity would receive the Congestion
Revenue Rights associated with the new transfer capability. In the past
the Commission has allowed credits for upgrades; is there still a role
for credits under Standard Market Design?
239. Customers that have not acquired Congestion Revenue Rights in
advance could schedule transmission service in the day-ahead market,
but they would not have the Congestion Revenue Rights protection
against congestion costs.
240. We propose that Congestion Revenue Rights be made available
first in the form of receipt point-to-delivery point obligation rights,
which we propose to mandate now, and later in the form of receipt
point-to-delivery point option rights and flowgate rights.
Currently, in PJM and New York ISO only receipt point-to-delivery
point obligations are offered. However, there has been considerable
interest expressed by market participants in other types of Congestion
Revenue Rights. For example, the Midwest ISO is considering offering a
package of Congestion Revenue Rights that are similar to what we are
proposing. Also, PJM is considering offering receipt point-to-delivery
point options. Offering several different types of Congestion Revenue
Rights would make the system more flexible and better able to adapt to
the needs of specific customers. Also, certain types of Congestion
Revenue Rights may be more valued in different regions of the country
based on the physical configuration of the transmission system and the
types of resources connected to that system. Various technical papers
over the last few years have examined offering these alternate rights
simultaneously and concluded that it is feasible under the conditions
now specified in the SMD Tariff.\134\ Therefore, we believe the tariff
should provide this flexibility.

b. Types of Congestion Revenue Rights
241. The SMD Tariff describes the characteristics of each of the
types of Congestion Revenue Rights. These descriptions are summarized
below.
(1) Receipt Point-to-Delivery Point Rights.
242. A receipt point-to-delivery point right is a right that is
specified by a receipt point (which can be a generator node, an
aggregation of generator nodes, an interface, a trading hub, or any
other collection of nodes) and a delivery point (which can be a
delivery node, an aggregation of delivery nodes, an interface, or a
trading hub), and the power in MW that is transmitted from the receipt
point to the delivery point for a period of time (e.g., one hour).
[[Page 55485]]
243. A receipt point-to-delivery point right entitles the holder to
the day-ahead congestion revenues associated with transmission service
from the receipt point to the delivery point.\135\ In addition, during
any period when the demand for transmission service cannot be met with
Available Transfer Capability (i.e., because there are too many
customers who have indicated that they want transmission service at any
price), holders of receipt point-to-delivery point rights would receive
priority over other market participants in scheduling transmission
service between the receipt point and delivery points designated in
their rights.
---------------------------------------------------------------------------
\135\ The right is direction-specific. The holder is entitled to
congestion revenues from the receipt to delivery point, not from the
delivery point to the receipt point.
---------------------------------------------------------------------------
244. A receipt point-to-delivery point right would provide the
holder with the right to schedule transmission service of the specified
amount of power (MW) in the day-ahead market from the receipt point to
the delivery point without paying any net charges for congestion
(although the holder would need to pay a charge for losses). The reason
is that every customer would be entitled to inform the Independent
Transmission Provider to schedule its transmission service regardless
of the congestion charge. In that case, the customer would be charged
for congestion (as well as for losses). But a self-scheduled customer
holding a receipt point-to-delivery point right for at least the same
amount of power between the same receipt and delivery points would
receive congestion revenues that fully offset the congestion charge.
(2) Obligations and Options.
245. Receipt point-to-delivery point rights can take the form of
obligations or options. The difference between obligations and options
becomes important when congestion occurs in the opposite direction from
the right, that is, when there is congestion from the delivery point to
the receipt point. In this case, congestion revenues in the direction
of the right are negative. Under a receipt point-to-delivery point
obligation, the Congestion Revenue Rights holder in that case would be
required to pay the negative congestion revenues to the Independent
Transmission Provider. Under a receipt point-to-delivery point option,
the Congestion Revenue Rights holder would not be required to pay the
negative congestion revenues to the Independent Transmission Provider.
Existing firm point-to-point transmission contracts under the Order No.
888 pro forma tariff do not require contract holders to transmit energy
and, thus, are similar to Congestion Revenue Rights that are options.
(3) Flowgate Rights.
246. A flowgate is a particular transmission facility or group of
facilities (e.g., an interface). A flowgate right specifies a portion
of the transmission capacity over that flowgate in a specified
direction. A flowgate right entitles the holder to the day-ahead
congestion revenues associated with the specified power flows over the
flowgate in the specified direction.
246a. Consider, for example, a very simplified transmission network
that connects two points, A and B, with two different but
interconnected transmission lines, a northern line and a southern line,
as shown below:
[GRAPHIC]
[TIFF OMITTED] TP29AU02.040
Each transmission line could be a separate transmission or flowgate,
and separate flowgate rights could be issued for each line. The holder
of a flowgate right on the northern line from west to east would be
entitled to the congestion revenues associated with that line in the
west-to-east direction. However, holding a flowgate right on the
northern line would not entitle the holder to congestion revenues
associated with the southern line. Hence, if transmission service
results in energy flows over several flowgates, the buyer must obtain
sufficient rights on each flowgate to obtain protection from congestion
charges. By contrast, the holder of a receipt point-to-delivery point
right from west-to-east (i.e., from A to B) would be entitled to
congestion revenues in the west-to-east direction regardless of whether
the northern or the southern lines were congested and thus would have a
complete hedge for this transaction.
246b. Unlike a receipt point-to-delivery point obligation, a
flowgate right would never require the holder to make congestion
payments. The congestion revenue associated with a flowgate in a
specified direction would equal the additional net economic value to
market participants that would result by incrementally increasing the
flowgate's capacity in the specified direction. That additional net
economic value may be either positive (i.e., when the flowgate is
congested) or zero (i.e., when the flowgate is not congested), but it
would never be negative.
247. Receipt-point-to-delivery-point rights offer the transmission
customer with long-term energy contracts the best way to protect itself
against hourly congestion costs. However, many transmission customers
may be meeting their loads' needs with a portfolio of generators
scattered around a regional electricity market. Such customers may be
seeking a more flexible type of right than the receipt-point-to-
delivery point right (which is typically only reconfigured on a monthly
basis and which can be traded on the secondary market most easily if
another customer requires the same points as specified in the right).
The major market advantage of the flowgate right is that since there
are fewer congested flowgates than possible under receipt-point-to-
delivery-point rights, transmission customers can focus their rights on
the key congested flowgates. This allows for coverage of much of the
congestion charges (in some estimates, between 80 percent to 90
percent). However, the flowgate rights may not provide a complete
protection against congestion charges for a receipt point-to-delivery
point energy transaction, since the congestion revenues may differ from
the congestion charges.
[[Page 55486]]
c. Requirement for Offering Rights
248. At the start of Network Access Service, the Independent
Transmission Provider would be required to offer receipt point-to-
delivery point obligations. These rights are the easiest to implement
because they are already in wide use. While we want the market to
develop additional choices for customers, we are concerned about
requiring implementation of numerous types of rights, including types
of Congestion Revenue Rights that have not yet been tested by an ISO or
RTO, when Standard Market Design is first implemented. Because there is
no experience with the other types of rights, we propose not to require
the Independent Transmission Provider to offer them initially. However,
upon the request of market participants, the Independent Transmission
Provider would be required to offer receipt point-to-delivery point
options and flowgate rights as soon as technically feasible.
249. Additionally, Congestion Revenue Rights could be offered for
various terms, e.g., one month or five years. Some customers may desire
Congestion Revenue Rights with multi-year terms to correspond to the
terms of long-term power contracts, including contracts used to satisfy
the resource adequacy requirement discussed in Section J. At the same
time, it may be difficult for the market to value long-term Congestion
Revenue Rights until a region has actual operating experience under an
LMP congestion management system. This could create problems in an area
that auctions all Congestion Revenue Rights and allocates the auction
revenue rights to load. We seek comment on whether the Commission
should require the Independent Transmission Provider to offer multi-
year Congestion Revenue Rights when Standard Market Design is first
implemented. Additionally, we seek comment on whether the Independent
Transmission Provider should be required to offer Congestion Revenue
Rights with terms tied to the planning horizon used in the region to
satisfy the resource adequacy requirement.
d. Funding for the Congestion Revenue Rights
250. As explained above, holders of Congestion Revenue Rights would
be entitled to receive congestion revenues associated with transmission
congestion in each hour of the day-ahead market. The aggregate amount
of Congestion Revenue Rights issued by the Independent Transmission
Provider would be the amount simultaneously feasible based on Available
Transfer Capability under normal operating conditions. As a result,
during normal operating conditions, the Independent Transmission
Provider would collect enough congestion charge revenue from users of
transmission service in the day-ahead market to fully pay the day-ahead
congestion revenues owed to holders of Congestion Revenue Rights.
Indeed, the Independent Transmission Provider might collect a surplus
of revenue in some hours during normal operating conditions. However,
when a significant amount of transmission facilities are out of
service, so that less transmission service can be provided, the
Independent Transmission Provider may collect less congestion charge
revenue from transmission users than the amounts owed to Congestion
Revenue Rights holders.
251. There are two ways to handle this revenue shortfall. First,
the amount of congestion revenues paid to the holders of Congestion
Revenue Rights may have to be reduced. As a result, the customer may
only be able to protect against a portion (e.g., 95 percent) of its
congestion costs in the day-ahead market. Alternatively, the customer
that has a Congestion Revenue Right could receive full protection
against congestion costs and the revenue shortfall would be assigned to
the transmission owner. We propose to use the latter approach. When
such revenue deficits arise, we propose that such deficits be made up
by transmission owners whose transmission facilities are out of
service. We would, however, include an exception for outages due to
force majeure events, since our intent is to reward transmission owners
for proactively maintaining their transmission facilities.\138,137\
Assigning revenue deficits in this way would encourage transmission
owners to take steps to minimize forced transmission outages and to
schedule maintenance outages so as to minimize their effect on
congestion costs. Assigning congestion revenue surpluses to
transmission owners may also encourage them to minimize outages.
However, such a policy may also create an interest on the part of
transmission owners in maintaining congestion, and thus may discourage
them from building needed transmission expansions. We propose that any
revenue surpluses be paid to transmission owners, but we seek comment
on the potential of this policy to discourage transmission expansions
and if alternative mechanisms should be used to distribute the revenue
surpluses.
---------------------------------------------------------------------------
\136,137\ As a result, in the event of force majeure the
Congestion Revenue Rights would not be fully funded.
---------------------------------------------------------------------------
e. Auctions and Resales of Congestion Revenue Rights
252. We believe it is important that there be an active secondary
market for Congestion Revenue Rights. This will allow a market
mechanism for customers that have Congestion Revenue Rights to acquire
new ones or to sell Congestion Revenue Rights they no longer need.
Additionally, this provides a way for market participants that do not
have Congestion Revenue Rights to acquire them. Market participants
would be allowed to resell any Congestion Revenue Rights that they have
been awarded for the full term of the rights or for a part of the term.
Resales could be transacted bilaterally between willing buyers and
sellers. In addition, we propose to require that the Independent
Transmission Provider conduct periodic auctions of Congestion Revenue
Rights. The Independent Transmission Provider's auction would allow
holders of rights to resell their Congestion Revenue Rights in an
organized market. This would provide greater price transparency for
these rights than if all sales were conducted through bilateral
transactions. Moreover, the auctions would provide the ability to
reconfigure Congestion Revenue Rights into different receipt and
delivery points, or into different types of rights (e.g., receipt
point-to-delivery point options, obligations, or flowgate rights). This
would allow Congestion Revenue Rights holders to change their
Congestion Revenue Rights if for example they decided to switch
suppliers. The auctions would also allow Congestion Revenue Rights
associated with other transmission capacity that becomes available
(such as through the expiration of previously issued Congestion Revenue
Rights) to be sold.
253. In the auctions, buyers and sellers would submit bids that
specify the type of Congestion Revenue Rights desired to be bought or
sold, the location, term and price. The Independent Transmission
Provider would select the combination of bids that maximizes the
economic value of the transactions for the participants. In so doing,
the Independent Transmission Provider must reconfigure the Congestion
Revenue Rights offered for sale in a way that maintains the
simultaneous feasibility of the Congestion Revenue Rights. That is, the
types and/or locations of the Congestion Revenue Rights offered for
sale may differ from those that are purchased. The Independent
Transmission Provider
[[Page 55487]]
would establish market-clearing prices for each Congestion Revenue
Right bought or sold. Each seller would receive the market-clearing
price for the rights that it sold, and each buyer would pay the market-
clearing price for the rights that it purchased.
f. Including Energy and Ancillary Services in the Congestion Revenue
Rights Auctions
254. The time period covered by the Congestion Revenue Rights sold
in auctions would be a month or longer. We propose that an Independent
Transmission Provider would be permitted, but not required, to conduct
pre-day-ahead auctions for energy and ancillary services. Under such
auctions, market participants could offer to buy and sell energy and
ancillary services at specific locations on a forward basis for a
specified time period, such as for a month or a year. Participation in
these pre-day ahead markets, as in all markets, would be on a voluntary
basis. Such purchases and sales of energy and ancillary service would
require use of the transmission system, just as sales of Congestion
Revenue Rights would. Thus, in conducting pre-day-ahead auctions, the
Independent Transmission Provider would allocate transmission capacity
among competing demands for Congestion Revenue Rights, forward energy
and forward ancillary services so as to maximize the economic value of
the winning bids. The Independent Transmission Provider would establish
market-clearing prices for forward energy and ancillary services at
each location, as well as market-clearing prices for Congestion Revenue
Rights.
255. A potential benefit of pre-day-ahead auctions is that they
could more easily maximize the economic benefits of transmission
capability by considering a greater array of competing uses of the
transmission grid. They could also provide a convenient, central market
forum for buyers and sellers to arrange forward trades of energy and
ancillary services. They could provide transparency and liquidity (and
thus protection against manipulation) in long-term markets where
liquidity has recently been reduced.
F. Day-Ahead and Real-Time Market Services
256. This section sets forth the bidding, scheduling, price
determination, and settlement provisions necessary to implement LMP in
the day-ahead and real-time markets for energy, regulation and both
operating reserves. In this section, we lay out the basic elements that
would be used for congestion management and operation of the spot
markets.\138\
---------------------------------------------------------------------------
\138\ Part I of the SMD Tariff includes a definition of the
terms related to market services. In addition, as we use the term
``supplier'' or ``seller'' in this Section, the definition we are
using includes both generators and demand-side resources that
satisfy the Independent Transmission Provider's applicable
requirements.
---------------------------------------------------------------------------
1. Design of the Day-Ahead Markets
257. We propose that the Independent Transmission Provider operate
day-ahead and real-time markets for energy and certain ancillary
services in conjunction with its scheduling of transmission service day
ahead and in real time. These markets would allocate transmission and
generation capacity among competing uses in different markets through
LMP pricing. For example, the markets would determine how much
transmission capacity would be allocated for transmission service to
market participants completing bilateral energy transactions, for use
by the Independent Transmission Provider in completing energy sales and
purchases through its bid-based energy markets, and for providing
ancillary services. The markets should be operated jointly to ensure
that transmission and generation capacity is allocated where it is most
valuable, and to ensure that the prices for the products and services
are internally consistent.
a. Scheduling Transmission Service Day Ahead
(1) General Features.
258. Each day the Independent Transmission Provider would accept
requests to schedule transmission service to support bilateral energy
transactions or customer-owned generation for each hour of the
following day. A customer desiring transmission service would be
required to submit a scheduling request in a standardized form
specified by the Independent Transmission Provider. For each requested
transmission service, the scheduling request would indicate the receipt
point and the delivery point of the bilateral energy transaction or
customer-owned generation, the amount of power (MW) to be transmitted
and the time period. To facilitate the ability of demand to respond to
price signals, transmission customers will be given several ways of
indicating their willingness to change their consumption based on
congestion costs and marginal losses: (1) Customers (whether or not
they hold Congestion Revenue Rights) would be allowed to specify in
their scheduling requests the maximum transmission usage charge
(reflecting the costs of congestion and marginal losses) at which the
customer desires service; \139\ (2) customers would be allowed to
specify the maximum congestion charge component of the transmission
usage charge at which they desire transmission service, or above which
they are unwilling to pay any congestion costs; or (3) customers
(whether or not they hold Congestion Revenue Rights) could submit a bid
that states a desire for transmission service to be scheduled
regardless of the transmission usage charge. This option may be useful
for a holder of a Congestion Revenue Right that desires to schedule
transmission service that uses the receipt point-to-delivery point
combination covered by that Congestion Revenue Right.
---------------------------------------------------------------------------
\139\ For example, when transmission usage prices become
sufficiently high, customers holding receipt point-to-delivery point
Congestion Revenue Rights may prefer not to schedule transmission
service between their designated receipt and delivery points.
Instead, the customers may prefer to receive the applicable
congestion revenues. Customers could communicate these preferences
through price-bids.
---------------------------------------------------------------------------
259. Another way that transmission customers will be able to
respond to price signals is by submitting multi-hour block bids,
requesting transmission service for a block of consecutive hours and
indicating the maximum price for the entire multi-hour period. For
example, a multi-hour block bid might specify that the customer desires
10 MW of transmission service from receipt point A to delivery point B
in each hour from 1 p.m. to 6 p.m. as long as the price per MW for the
entire 5-hour period does not exceed $10. Such a bid would be accepted
if the sum of the hourly transmission usage prices for each of the 5
hours did not exceed $10. Otherwise, the entire bid would be rejected.
This option allows a customer, for example an industrial customer in a
state with retail access, to indicate that it is willing to reduce its
transmission usage if the prices for a multi-hour period are above a
specified level. This feature has not been put in practice in any of
the bid-based markets operated by ISOs. We seek comments on its merit
and any implementation difficulties.
260. The Independent Transmission Provider would consider these
transmission scheduling requests in conjunction with bids submitted in
its day-ahead energy and ancillary service markets. Based on all of
these, the Independent Transmission Provider would accept the set of
energy bids and scheduling requests and develop a day-ahead schedule
that maximizes the economic value for all market participants. The
Independent Transmission Provider would also
[[Page 55488]]
establish transmission usage prices for each hour of the next day that
are the same as the implicit transmission usage price included in the
set of locational energy prices (i.e., the difference in the price of
energy at the receipt point and at the delivery point, which reflects
both congestion and losses).
261. The Independent Transmission Provider would schedule all
requests for transmission service since these users have agreed to pay
any applicable congestion charges. The Independent Transmission
Provider would also schedule all requested transactions where the
transmission usage charge was below the amount the customer indicated
it was willing to pay.
262. Customers with Congestion Revenue Rights would receive
congestion revenues that help offset any congestion charges paid as
part of the transmission usage charge. The amount of the congestion
revenues received (and the associated protection against congestion
charges) would depend on the specific Congestion Revenue Rights held. A
customer holding receipt point-to-delivery point Congestion Revenue
Rights for a certain amount of power between a delivery and receipt
point that matches its day-ahead transmission schedule would receive
congestion revenues that exactly offset its congestion charges, so that
its net bill would reflect no congestion charges (although it would be
charged for losses).
263. The above process would be used for scheduling transmission
service on a daily basis. Some customers, particularly those with
Congestion Revenue Rights, may desire to schedule the same exact
service over a longer period to save on administrative costs. The
Commission seeks comments on whether a customer should be allowed to
provide a schedule for multiple days or have a standing scheduling
request that would remain in effect until changed by the customer. Any
schedule request, once scheduled by the Independent Transmission
Provider would become financially binding on the customer at the close
of each day's day-ahead market.
(2) Transmission Service Across Borders.
264. Transmission service across the border of adjoining
Independent Transmission Providers' service areas--from a point of
receipt in one service area to a point of delivery in another--requires
coordination between the affected Independent Transmission Providers.
When transmission congestion exists between a point of receipt and a
point of delivery in different service areas, managing the congestion
becomes more difficult because more than one Independent Transmission
Provider is involved.
265. There are at least two methods for arranging for transmission
service across borders--physical reservations (i.e., continuing firm
point-to-point reservations of transfer capability), and scheduling of
service consistent with internal transactions under Network Access
Service (scheduling of transmission and financial bidding). We propose
to treat transmission service across borders in the same way as
internal transactions. Thus, like internal transactions, an importing
or exporting customer could either schedule transmission service and
agree to pay the transmission usage charge regardless of the level or
submit a bid that limits its congestion exposure. Under the first
method, the transmission customer would submit to each Independent
Transmission Provider a request to be scheduled for transmission
service to and from the border, regardless of the applicable
transmission usage charges that it will be assessed. The customer would
be scheduled unless congestion arose that could not be relieved through
redispatch or some other means. Under the second method, financial
bidding, the customer would submit a price bid to each Independent
Transmission Provider indicating the maximum transmission usage charge
that it is willing to pay for transmission service on each side of the
border. The customer would be scheduled if its price bid on each side
of the border was at or above the applicable transmission usage charge.
Under either method, if the customer's transaction is scheduled, the
customer would pay the applicable transmission usage charges to and
from the border. We propose to make both options available to
transmission customers, because each option may provide benefits to
customers. We would prefer ``one-stop shopping'' with Independent
Transmission Provider coordination; we seek comment on whether this can
be done?
266. Recently we accepted a prescheduling option for service across
borders that was proposed by the New York ISO.\140\ A prescheduling
option would give a customer certainty prior to the day-ahead market
that it could transmit power across a border. Under the New York ISO's
prescheduling option a customer may schedule such a transaction up to
eighteen months in advance of the dispatch day. A customer that
requests a prescheduled transaction agrees to pay the applicable market
clearing transmission usage charge. Once submitted, the transaction
would be financially binding unless the New York ISO permits the
customer to withdraw the prescheduled transaction. We seek comment on
whether a similar prescheduling option should be included in Standard
Market Design.

---------------------------------------------------------------------------
b. Transmission Losses
267. When energy is transmitted from a point of receipt to a point
of delivery, some of the energy is lost due to resistance on the wires.
These transmission losses are a cost of transmission and commonly are
recovered on an average cost basis from all transmission customers. As
noted earlier, we are proposing that energy prices and the associated
transmission usage charges be based on marginal costs, in order to
promote economic efficiency. We seek comment on whether transmission
losses should be recovered on the basis of the marginal cost of losses
or if they should be recovered on the average cost of losses. There are
advantages and disadvantages to each approach. Using marginal losses
would promote a more efficient use of the transmission system. However,
as discussed below, charging marginal losses will collect surplus
revenues that must then be returned to transmission customers. On the
other hand, the advantage of charging average losses is simplicity. If
average losses are charged, the losses collected from customers would
equal actual losses. There would be no need to create a mechanism to
return surplus losses.
268. For customers purchasing transmission service to complete
bilateral transactions, we see value in allowing transmission customers
to pay for their assigned losses either in cash or in kind. To pay in
cash, the customer would pay the market price for its assigned MWhs of
losses, which would be included in the applicable transmission usage
charge. Thus, the MWh of energy injected at the point of receipt would
equal the MWh withdrawn at the point of delivery. The transmission
provider would procure the energy used for losses from its energy
market. To pay in kind, the customer would supply energy at the point
of receipt in the amount of its assigned losses. Thus, the MWhs
injected at the point of receipt would exceed the MWhs at the point of
delivery by the amount of the assigned losses, and the customer would
pay in cash only the congestion component of
[[Page 55489]]
the transmission usage charge.\141\ We note, however, that some
commenters in our outreach process expressed concern that allowing
customers to provide losses in kind may unduly complicate the
scheduling process, especially for transactions that involve multiple
Independent Transmission Providers. We seek comment on whether
transmission customers should have the choice of paying for losses in
cash or in kind, or alternatively, whether all transmission customers
should be required to pay for losses in cash.
---------------------------------------------------------------------------
\141\ The amount of energy needed for losses would not be known
until the close of the market. For transactions in the day-ahead
market, the Transmission Provider would inform each customer that
wishes to supply losses in kind (after the close of the day-ahead
market) of the amount of its assigned losses (in MWh), and that
amount would be included in the customer's day-ahead schedule. For
transactions in the real-time market, the Transmission Provider
could provide an estimate in advance of the amount of each
customer's assigned losses. However, since actual marginal losses
would not be known until after the fact, the customer would be
charged or credited at the applicable LMP for any under- or over-
provision of losses.
---------------------------------------------------------------------------
c. Day-Ahead Energy Market
(1) General Features.
269. We propose that the Independent Transmission Provider be
required to run a voluntary, bid-based, security-constrained day-ahead
energy market. ``Voluntary'' means that market participants do not have
to buy or sell in the day-ahead energy market. The day-ahead market we
are proposing provides customers with additional supply choices. It is
not intended to substitute for other longer-term arrangements that
customers may use to purchase supplies such as bilateral transactions
or use of a customer's own generation. Thus, market participants would
be able to schedule bilateral transactions and/or their own generation
rather than bid into the day-ahead energy market. ``Bid-based'' means
that participants may submit offers to buy or sell quantities of energy
into the market and may specify the prices at which they are willing to
transact. This provides an organized and transparent system for the
Independent Transmission Provider to determine the marginal cost of
relieving transmission congestion. ``Security-constrained'' means that
the Independent Transmission Provider, in the energy auction process,
takes account of all system constraints, such as contingency limits,
needed for reliable system operations and develops a schedule that does
not violate such constraints. This is necessary to ensure that the day-
ahead schedule is physically feasible. Otherwise, the Independent
Transmission Provider might be required to make additional payments in
real time to relieve congestion, which could provide an incentive for
market participants to create congestion in the day-ahead market to
receive these payments in the real-time market.\142\ The market should
allow full participation by both the supply side and the demand side of
the market.
---------------------------------------------------------------------------
\142\ See the discussion of this issue in Appendix E.
---------------------------------------------------------------------------
(2) Bidding and Scheduling Rules.
270. Each day, the Independent Transmission Provider would accept
bids to sell and buy energy for each hour of the following day.
Participants desiring to sell or buy energy would submit a bid in a
standardized form.
271. Each seller's bid would indicate the amount of power (MW)
offered to be sold, the receipt point, and the time period. In
addition, each seller would be allowed to submit multi-part bids that
separately specify bid prices for start-up, no-load, and energy, as
well as technical characteristics such as ramp rates, minimum run times
and minimum down times. Allowing suppliers' bids to include these items
yields more detailed information that can improve the ability of the
grid operator to dispatch suppliers with the lowest total cost. For
example, if the supplier were required to submit a one-part bid it
would need to include start-up costs in its energy bid, resulting in a
higher energy price bid. However, a supplier submitting a bid that
separately specified the energy bid and the start-up costs would not
have to make these estimates and the grid operator would use the bids
to dispatch the supplier with the lowest total cost. Suppliers would
also be allowed to submit bids that are self-schedules, that is, that
would indicate an amount to be supplied at a location regardless of the
applicable energy price. The supplier would receive the applicable
market clearing price for its energy. This option may be useful for
suppliers with very high start-up costs such as nuclear facilities.
Intermittent resources would be able to participate in the day-ahead
market on the same basis as other resources.
272. Similarly, each buyer's bid would indicate the desired amount
of power (MW) to be bought, the delivery point, and the time period. In
addition, each buyer would be allowed to specify bid prices that
indicate the quantities it is willing to purchase at alternative
prices. Buyers would also be allowed to submit multi-part bids that
indicate the time and price constraints under which they are willing to
purchase energy. These options would facilitate demand response
programs because they allow the buyer to indicate the price at which it
will voluntarily reduce its consumption. Buyers would also be allowed
to schedule an amount to be purchased regardless of the applicable
energy price.\143\ Bids would not need to be tied to a physical
generator or load resource. However, for reliability purposes, bids
would need to indicate whether they were purely financial bids or
whether they were tied to a physical resource. This would permit market
participants to bring day-ahead and real-time prices closer together,
increasing the stability of both markets. This option should reduce
price differences between these two markets.
---------------------------------------------------------------------------
\143\ Since energy prices have the potential to rise to very
high levels, it may be necessary to require buyers that request
energy without submitting a price bid to demonstrate to the
Independent Transmission Provider in advance that they are
financially capable of paying very high prices for such quantities.
Alternatively, the Independent Transmission Provider could limit the
amounts based on a buyer's creditworthiness.
---------------------------------------------------------------------------
273. Buyers and sellers would be able to submit different price
bids for different hours of the day, and bids could vary from day to
day. However, if market participants can exercise market power, limits
may be imposed on bidding to mitigate market power, as discussed below
in the section addressing market power monitoring and mitigation.
274. We propose a scheduling option to address the special
conditions facing energy-limited resources such as hydroelectric and
environmentally constrained thermal resources. These resources are
limited in the amount of energy or the number of hours that they can
produce energy over a period of time. As a result, production in one
hour may reduce the amount of energy that the resource can produce (and
the associated revenue) in other hours. Energy-limited suppliers could
submit bids in the day-ahead market that specify the amount of energy,
or the number of hours, available for production over the next day. The
supplier could then request the Independent Transmission Provider to
schedule its energy in those hours of the next day when the energy
price is highest. Such a scheduling feature would promote efficient
scheduling because it would allow the energy-limited resource to be
scheduled where its energy would have the greatest value, with maximum
profit to the resource owner.\144\ We recognize that the
[[Page 55490]]
resource mix varies significantly from region to region and that some
regions, such as the Northwest, have a greater amount of energy limited
resources. We seek comment on whether other scheduling options or
regional variations should be included for energy-limited resources in
the tariff.
---------------------------------------------------------------------------
\144\ While this scheduling feature is intended mainly for
energy-limited resources, it would be available to all generators
and would not be restricted to energy-limited resources, unless such
restrictions are necessary to mitigate market power.
---------------------------------------------------------------------------
275. We recognize that intermittent resources such as wind power
may also benefit from scheduling rules that recognize their inability
to precisely control output. We recently approved a special mechanism
for intermittent resources selling into the energy market run by the
California ISO.\145\ Under that mechanism, the intermittent resource
and the California ISO work together to develop a schedule and
procedures for accurately forecasting the output of the resources.
However, California ISO currently runs only a real-time market for
energy and not both a day-ahead market and real-time market as proposed
here. Also, the amount of power produced by intermittent resources
within California is much larger than in many parts of the country. We
propose to include the California ISO's scheduling option for
intermittent resources as part of Standard Market Design. However, we
seek comment on whether there is a better way to schedule intermittent
resources.
---------------------------------------------------------------------------
\145\ See California Independent Operator Corp., 98 FERC [para]
61,327, order accepting compliance filing, 99 FERC [para]
61,309
(2002).
---------------------------------------------------------------------------
276. Finally, in drafting the bidding and scheduling rules we have
included several ways for demand to respond to prices. We recognize
that several ISOs currently have demand response programs that operate
differently. Under these demand response programs, the ISO pays end-
users to reduce their demand if market clearing prices reach a certain
level. We believe the direct approach of letting demand bid in the
market will be less costly than a program where an end-user receives
payments greater than the market clearing price to reduce its demand.
We have not proposed to include these types of programs in the pro
forma tariff although they could be included if the Independent
Transmission Provider, in consultation with the state advisory
committee and stakeholders, determined that they were necessary. Since
the participation of demand in the market is critical for an effective
wholesale market, we seek comment on whether the measures proposed are
sufficient or if other measures should be included.
(3) Price Determination and Settlement.
277. Based on the accepted bids included in the day-ahead schedule,
the Independent Transmission Provider would establish day-ahead
locational energy prices for each hour. The hourly energy price at each
location would reflect the marginal cost (as reflected in bids) of
producing and delivering energy to that location in that hour. Energy
prices would be consistent with the transmission usage charges, so the
difference in energy prices between two locations in an hour would
reflect the cost of transmitting energy from one location to the other.
278. The Independent Transmission Provider would establish a single
market-clearing energy price for each hour for each node on its
transmission system. We believe it is important that energy prices be
calculated for each node to avoid socialization of congestion costs and
to reduce the possibility of manipulating the congestion management
system.\146\ The Independent Transmission Provider could also establish
nodal prices for time intervals shorter than an hour. Nodal pricing
would be used for both buyers and sellers in the day-ahead market.
---------------------------------------------------------------------------
\146\ See discussion in Appendix E of manipulation strategies
involving congestion management.
---------------------------------------------------------------------------
279. Upon request of market participants, the Independent
Transmission Provider would establish trading hubs. A trading hub is a
virtual location where financial transactions may be arranged, whose
hub price is the weighted average of energy prices at a specified set
of nodes on the transmission system. A trading hub facilitates
financial trading and aggregation of supplies from multiple sources.
Creation of trading hubs should not lead to socialization of congestion
costs, because the price for service at the trading hub is the weighted
average of prices at the various nodes that are included in the trading
hub. Energy may not be injected or withdrawn from the grid at a trading
hub, since a hub does not exist at a physical location. But a hub may
be named as an intermediate point between physical points of injection
and withdrawal where financial energy trades may occur.\147\ Also, at
the request of market participants, the Independent Transmission
Provider would establish zones that are the weighted average of energy
prices at selected delivery nodes on the transmission system. This
option would permit a load-serving entity to aggregate prices for
deliveries to its various delivery nodes.
---------------------------------------------------------------------------
\147\ A good example of a trading hub is PJM's Western hub,
where there are active spot energy and transmission rights markets,
as well as bilateral markets.
---------------------------------------------------------------------------
280. Each buyer and seller would transact at the applicable
clearing price for the hour and time period. A seller that submits
separate bids for start-up and no-load costs and is dispatched by the
Independent Transmission Provider for any period during the day, will
be assured that it will recover the start-up and no-load costs that it
bid. If a seller's total bid costs (including start-up and no-load
costs, as well as energy running costs) over the entire day are not
fully covered by its revenues from selling at the hourly clearing
prices, it would receive an additional payment (i.e., an ``uplift''
payment) for the net revenue shortfall for the day. Hourly energy
prices would be based only on energy bids; start-up cost bids and no-
load bids would not be used in calculating hourly energy prices. Thus,
a generator may have legitimate start-up costs that are not fully
covered by selling at the hourly energy price over the day; paying
uplift may be necessary to ensure that generators selected in the
auction will receive revenues that fully cover their bid-costs.\148\
Since the additional payments are a cost of providing supplies of
energy and ancillary services in the Independent Transmission
Provider's day-ahead market, we propose to recover the additional
payments from entities that purchase energy and/or ancillary services
in the Independent Transmission's Provider's day-ahead market. Any
entity that does not buy any energy from the Independent Transmission
Provider's day-ahead market on a given day, and that self-supplies all
of its ancillary service obligations on that day, would
[[Page 55491]]
not be assigned a share of the additional payment for that day.
---------------------------------------------------------------------------
\148\ For example, suppose that the Independent Transmission
Provider needs to supply an additional 100 MW load in each of 20
hours over the next day. Two generators, A and B, are available.
Generator A has energy costs of $35/MWh, but must incur $15,000 in
start-up costs before beginning production. Generator B has energy
costs of $40/MWh, and has no start-up costs. Generator A's total
cost of meeting the load would be $85,000 (i.e., total energy costs
of $70,000 [$35/MWh x 100 MWh x 20 hrs]
PLUS start-up costs of
$15,000). Generator B's total cost would be $80,000, comprised
exclusively of energy costs (i.e., $40/MWh x 100 MWh x 20 hrs).
Generator B should be chosen because its total costs ($80,000) would
be less than Generator A's total costs ($85,000). Suppose that the
hourly clearing price in each hour is $42/MWh. By selling 100 MWh in
each of 20 hours, Generator B would receive total revenues of
$64,000 (i.e., $32/MWh x 100 MWh x 20 hrs), which is $6,000 less
than its total bid-in costs of $70,000. Generator A would thus need
to receive a $6,000 uplift payment in addition to its energy
revenues. Paying $6,000 in uplift is still cheaper for customers
than the alternative of dispatching Generator B.
---------------------------------------------------------------------------
281. The results of the day-ahead market would be financially
binding on buyers and sellers. That is, sellers would be paid the
applicable locational day-ahead price for energy scheduled to be sold
in the day-ahead market, and buyers would pay the applicable locational
day-ahead price for energy scheduled to be bought in the day-ahead
market. In addition, to the extent sellers and buyers fail to actually
produce or take energy according to their respective schedules in real
time, such imbalances would be settled at the applicable real-time
energy price. Thus, a seller would pay the real-time LMP nodal price
for any scheduled energy that it fails to deliver in real time to its
bid delivery point. Similarly, a buyer would be paid the applicable LMP
nodal real-time price for any scheduled energy that it does not take at
its bid receipt point in real time.
282. The Independent Transmission Provider would post prices and
other market information and settle the markets promptly to provide
market participants with reliable information regarding their market
transactions.
283. In certain instances, a generator may alleviate a voltage or
stability constraint by producing real power and/or reactive power at
its location. By alleviating the constraint, the transfer capability of
the grid may be increased, thereby allowing a greater amount of lower-
cost energy to be transmitted to an area with higher energy prices. For
example, the transmission capability to import power into a load pocket
may initially be limited to 1000 MW due to a voltage or stability
constraint, even though the thermal limit is 1500 MW. However,
production of an additional 100 MW of real power and/or an additional
amount of reactive power within the load pocket could increase import
capability into the load pocket by 50 MW, to 1050 MW. We seek comment
on whether generators who provide such real or reactive power should
receive additional compensation (in addition to the locational market
price for energy and the applicable compensation for reactive power)
for the additional transfer capability that they create, to provide
incentives to produce energy that increases transfer capability. For
example, should such generators be given the Congestion Revenue Rights
with the additional transfer capability that they create? In certain
circumstances, a generator must reduce its production of real power in
order to increase its production of reactive power. In these
circumstances, should the generator be compensated for the opportunity
cost of its reduced profits from selling real power? Should the
generator be paid the higher of its opportunity costs or the market
congestion value of the additional transfer capability created? How
should locational market power concerns be addressed in these
circumstances?
d. Day-Ahead Ancillary Service Markets
(1) General Features.
284. Order No. 888 identified six ancillary services. Under this
proposed rule, all six ancillary services must be provided by the
Independent Transmission Provider, but the three listed below need not
be obtained from the Independent Transmission Provider:\149\
(1) Regulation and frequency response
(2) Operating reserve--spinning
(3) Operating reserve--supplemental
Transmission customers may meet their responsibility through self-
supply, by procuring these ancillary services from a third party, or by
acquiring them from the Independent Transmission Provider.
---------------------------------------------------------------------------
\149\ The remaining ancillary services that must be obtained
from the Independent Transmission Provider are (1) Scheduling,
System Control and Dispatch Services, (2) Reactive Supply and
Voltage Control Service, and (3) Energy Imbalance Service. We seek
comment on treating Scheduling, System Control and Dispatch Services
as a basic cost of providing transmission service instead of as an
ancillary service.
---------------------------------------------------------------------------
285. As discussed earlier, imbalance energy would be provided
through the day-ahead and real-time energy markets. For the remaining
three ancillary services (regulation and both operating reserves), we
propose to require that the Independent Transmission Providers operate
bid-based markets open to all potential suppliers so that Independent
Transmission Providers can procure these ancillary services from the
lowest cost suppliers. Different regional reliability authorities may
establish different requirements for operating reserve--supplemental.
For example, the four jurisdictional operating ISOs procure resources
for the ancillary service operating reserve--supplemental (which are
usually generation resources that are not synchronized with the grid or
demand-side resources that can curtail use), with varying response
times. Each ISO procures a portion of their necessary operating
reserve--supplemental requirement with reserves that can respond within
10 minutes of a dispatch request, as well as slower-responding reserves
at 30 minutes (New York ISO and ISO-New England) and 60 minutes
(California). Since different regional reliability authorities have
established different response times for operating reserve--
supplemental, we do not propose a standard set of markets for operating
reserve--supplemental. However, we propose to require that each
Independent Transmission Provider operate separate markets for each
type of operating reserve--supplemental that it procures.
286. Location-specific reserve targets may be required in some
areas due to persistent and significant congestion. The Independent
Transmission Provider would identify and establish these targets
consistent with any reliability rules.
(2) Bidding and Scheduling Rules.
287. Each day, the Independent Transmission Provider would
determine the total amount of each of the ancillary services that will
be required for each hour of the following day. Customers that wish to
meet their ancillary service requirement through self-supply or
procurement through a third party would be required to provide the
Independent Transmission Provider with the necessary information about
the generation capacity or demand-side resource that would be providing
the ancillary services (as is currently required under the existing pro
forma tariff).
288. To procure the remaining amount of ancillary services, the
Independent Transmission Provider would accept bids for regulation and
the types of operating reserves for each hour of the following day. A
participant desiring to sell regulation or operating reserves would
submit a bid in a standardized form specified by the Independent
Transmission Provider. Bids could be offered to provide ancillary
services from generation capacity or any demand-side resource that
meets the technical requirements of the ancillary service. Participants
could offer the same capacity in more than one ancillary service
market, as well as in the energy market.
289. Each bid would indicate the type of ancillary service, the
amount of generating capacity (MW) offered for sale, the receipt point
of the resource and the time period. The bid would also include an
availability bid indicating the minimum price per MW (which could be
either a positive amount or zero) required to provide the ancillary
service. The availability bid would allow the bidder to ensure that it
would not be selected to provide the ancillary service unless the
ancillary service price is high enough to cover out-of-pocket costs,
such as the costs of keeping a crew at its facility for the following
day. The bid would also include the various components that would be
submitted to
[[Page 55492]]
provide energy into the energy market. These components include an
energy bid, indicating the minimum price per MWh required to produce
energy. Other bid components would include price-bids for start-up and
no-load, as well as technical constraints, such as minimum load, ramp
rates, minimum run time and minimum down time. By providing one
ancillary service, a bidder may forgo profits from sales in other
markets, and these forgone profits are an opportunity cost of providing
ancillary services. As explained in the following section, the
Independent Transmission Provider will consider the opportunity cost
associated with forgone sales in other markets operated by the
Independent Transmission Provider. Opportunity costs from forgone sales
in markets not operated by the Independent Transmission Provider could
be included in the bidder's availability bid.
290. The Independent Transmission Provider would consider all bids
to sell ancillary services, in conjunction with bids submitted in its
day-ahead markets for energy and transmission service. As noted
earlier, based on all submitted bids, the Independent Transmission
Provider would maximize the economic value (as reflected in the bids)
of the accepted bids, i.e., accept the bids with the overall lowest
cost. Thus, for generation capacity and demand-side resource that bid
into more than one market, the Independent Transmission Provider would
schedule the generation capacity or demand-side resource into the
market where it is most efficient (unless it is not efficient to
schedule the generation capacity or demand-side resource in any
market).\150\ This should yield the overall lowest cost for procuring
energy, regulation and operating reserves.
---------------------------------------------------------------------------
\150\ Because of the way that prices would be established in
each market, the market into which each bidder of generation
capacity or demand-side resource is scheduled would also be the
market that is the most profitable for the bidder. That is because,
as discussed in the following section, the prices in each market
would reflect marginal opportunity costs of the bidders in that
market. Thus, the price in each market would be high enough to allow
each accepted bidder in that market to receive at least as much
profit as it could have received in any other market operated by the
Independent Transmission Provider that it is technically capable of
participating in.
---------------------------------------------------------------------------
(3) Price Determination and Settlement.
291. Based on the accepted bids included in the day-ahead schedule,
the Independent Transmission Provider would establish day-ahead prices
for each of the ancillary services procured in the bid-based markets
for each hour. In regions with separate locational ancillary service
requirements, the Independent Transmission Provider would establish
separate hourly locational ancillary services prices.
292. To promote an efficient market, the price for regulation and
operating reserves services would equal the marginal cost of each
service, which would equal the highest accepted total bid cost
expressed in dollars per MW. The total bid cost of each generator is
the sum of: (1) The generator's availability bid per MW and (2) the
opportunity cost of forgoing sales in other markets operated by the
Independent Transmission Provider, expressed on a per-MW basis.\151\
---------------------------------------------------------------------------
\151\ Because prices are determined hourly, an opportunity cost
expressed in dollars per MWh converts to an equivalent dollar-per-MW
basis.
---------------------------------------------------------------------------
293. A generator or demand-side resource could be eligible to bid
into more than one market operated by the Independent Transmission
Provider. The opportunity costs paid to the supplier would be the
forgone profit from the most profitable other market. For example, a
generator that is capable of providing ancillary services could also
sell into the transmission provider's day-ahead energy market, although
it would incur additional variable energy costs to do so. Thus, the
forgone profit from selling into the energy market (as reflected in the
generator's bid) would be the difference between the energy price and
the generator's energy bid. The opportunity cost of selling ancillary
services would include this forgone energy profit.
294. The hourly price for one of these ancillary services in a
given location would thus equal the sum of the opportunity cost and the
availability bid in dollars per MW of the most expensive unit accepted
to provide that type of ancillary service in that hour to that
location. As noted above, a generator providing any ancillary service
is also technically capable of providing a slower response ancillary
service. For example, a generator providing operating reserve--spinning
could also provide operating reserve--supplemental. Thus the
opportunity cost of providing operating reserves--spinning would be at
least as high as the price of operating reserve--supplemental. As a
result, the marginal cost (and thus, the price) of operating reserve--
spinning would not be less than the price of operating reserve--
supplemental in the same hour.
295. Although suppliers bid to provide these ancillary services in
the day-ahead market, customers pay for them based on real-time load.
Transmission customers would be assessed a pro rata share of the total
ancillary service requirements for each of these three ancillary
services in each hour, based on their real-time, load-ratio share.
Ancillary service requirements generally depend more on real-time
transactions than on day-ahead schedules. Assessing ancillary service
requirements based on day-ahead schedules would provide an incentive
for customers to understate their day-ahead schedules.
296. In Order No. 888, exports are not charged for these ancillary
services. We ask for comments on whether they should be charged here.
297. Customers that want to self-provide or procure their own
ancillary services would be required to notify the Independent
Transmission Provider in the day-ahead scheduling process and identify
the resources that would be used to provide these services. Customers
would be given credit for the amount of ancillary services that they
self-provide or procure from third parties. Customers that self-provide
or procure from third parties more capacity than their requirements
would be paid the applicable hourly ancillary service price for the
excess if needed by the market.\152\
---------------------------------------------------------------------------
\152\ Since the customer's day-ahead schedule was based on its
projected share of the ancillary service requirement, it may have
procided more than its actual share in real time. Thus, the customer
would be comlpensated for the additional amounts it provided.
---------------------------------------------------------------------------
2. Scheduling After the Close of the Day-Ahead Market
a. Replacement Reserves
298. The Independent Transmission Provider will use the day-ahead
market to develop prices and a schedule for suppliers. The prices and
schedules will be based on the bids submitted by buyers and sellers.
However, the day-ahead schedule may be less than the forecasted load in
real time and, if so, the Independent Transmission Provider would
commit additional units to ensure that load can be met reliably in real
time.
299. After the Independent Transmission Provider has established a
day-ahead schedule and associated prices for energy, transmission
service and ancillary services, it would make its own forecast of load
within its market area for each hour of the following day. To the
extent that its forecasted load exceeds the amount of energy scheduled
to be delivered to load in the day-ahead schedule, the Independent
Transmission Provider may need to procure additional reserves (called
``replacement'' reserves) from generators to make up the difference,
but only to
[[Page 55493]]
the extent necessary to ensure that sufficient generation will be
available to meet load.
300. To procure replacement reserves, the Independent Transmission
Provider would accept bids from generators submitted for the day-ahead
market. The Independent Transmission Provider would select generators
to provide replacement reserves so as to minimize the costs of
availability, start-up costs and no-load costs regardless of energy
costs. This approach to procuring replacement reserves would provide an
incentive for load to accurately bid its load in the day-ahead market
since energy prices may be higher in the real-time market.
301. As discussed further in the next section, generators selected
to provide replacement reserves would be included in the real-time
energy bid stack along with other generators that submit bids into the
real-time market to provide energy. Generators selected to provide
replacement reserves would be paid the applicable real-time energy
price for energy that they produce. If a generator's revenues received
from selling real-time energy are less than its bids for availability,
start-up, no-load and energy, the Independent Transmission Provider
would pay the generator an additional payment (i.e., an ``uplift''
payment) for the shortfall. The revenue shortfall would be recovered
pro rata from all loads that buy energy in real time that have not been
scheduled in the day-ahead market. Thus, the costs would be allocated
to the customers that benefitted from the replacement reserves--
customers that took power in real time. This provides an incentive for
load to accurately predict its requirements in the day-ahead market.
302. We propose to add a new Section G.2 to the pro forma tariff
that would implement the foregoing procedures for scheduling and paying
for reserves after the close of the day-ahead market.
b. Changes to Transmission Schedules
303. A market participant that has not scheduled transmission
service in the day-ahead market but desires transmission service in
real time must inform the Independent Transmission Provider within
specific time deadlines before real time. Market participants may
change their day-ahead transmission service schedule by informing the
Independent Transmission Provider consistent with the time deadlines.
304. Participants that have informed the Independent Transmission
Provider of their desired changes within the Independent Transmission
Provider's lead times, and adhere to the requested changes in real
time, would settle the changes in transmission service at the
applicable real-time transmission usage prices, described more fully
below. Participants with new or increased transmission service would be
charged the applicable real-time transmission usage price between the
applicable receipt and delivery points for the new or increased
transmission service in the applicable hour. Conversely, participants
that reduce transmission service in real time (compared to the day-
ahead schedule) would be paid the applicable hourly real-time
transmission usage price for the applicable receipt and delivery
points, to compensate them for the additional transmission capacity
they have made available in real time.
3. Design of the Real-Time Markets
305. Under Standard Market Design, the Independent Transmission
Provider would be required to operate bid-based, security-constrained
real-time markets for transmission service, energy, and certain
ancillary services (i.e., regulation, operating reserve--spinning and
operating reserve--supplemental).
a. Real-time Energy Markets
(1) General Features.
306. Under the Standard Market Design, the Independent Transmission
Provider would accept bids to buy and sell energy in each hour in the
real-time energy market. The bids would be in the standardized form
specified by the Independent Transmission Provider. Real-time energy
markets would be used to provide the energy imbalance service of Order
No. 888 pro forma tariff. However, loads could voluntarily enter into
bilateral contracts with suppliers in advance to lock in a fixed price
for energy.
(2) Bidding and Scheduling Rules.
307. In general, bids would indicate an offer to depart in real
time from the bidder's day-ahead schedule to purchase or sell energy
(including a day-ahead schedule to purchase or sell 0 MWhs of energy).
Real-time bids would be accepted from any market participant, including
generators, load-serving entities, eligible retail buyers, marketers
and other agents. Bids would indicate the increase or decrease (in
MWhs) from the day-ahead schedule in the amount of energy to be sold or
purchased in real time, and the location and the hour of the changed
purchase or sale. Each participant bidding into the real-time energy
market would be allowed to include multi-part price bids similar to
those allowed in the day-ahead energy market (this is a departure from
the Working Paper).
308. The transactions in real time vary from those reflected in the
day-ahead schedule due to a variety of factors, including changes in
weather conditions and unexpected equipment outages. The Independent
Transmission Provider may be informed in advance of some of the
scheduling departures under the procedures described above; other
departures may occur without warning.
309. As occurs today, an Independent Transmission Provider will
have to adjust energy production and/or load at various locations in
order to balance generation with load and manage congestion. Under
Standard Market Design, the Independent Transmission Provider would
make these adjustments by calling upon participants that have submitted
bids into the real-time energy market, as well as participants that
have been selected to provide spinning, supplemental, and replacement
reserves. The Independent Transmission Provider would issue dispatch
instructions to bidders so as to balance generation and load, and
efficiently manage congestion of demand and supply.
(3) Price Determination and Settlement.
310. The Independent Transmission Provider would determine energy
prices in the real-time energy market for each node for each 5-minute
period or other subhourly period where a 5-minute determination is not
technically achievable. Each price would reflect the marginal cost (as
reflected in the real-time supply and demand bids) of producing energy
and delivering it to the node in that period. The Independent
Transmission Provider would post prices and other market information
and settle the markets promptly to give market participants reliable
information regarding their market transactions.
311. To promote efficient participant decisions regarding real-time
transactions, we propose that all departures in real time from the day-
ahead schedule be settled through the real-time market at the
applicable price (as is done today in many markets). Nodal pricing
would be used for both buyers and sellers in the real-time market.
312. There are several aspects of the design of the real-time
energy market where we seek additional comments.
Ex Post Versus Ex Ante Prices
313. This Section discusses how to determine real-time energy
prices. The options are to set the prices using near
[[Page 55494]]
real-time estimates (ex ante), or base the price on the price of the
actual marginal resource clearing the market in real time (ex post).
Immediately in advance of each upcoming 5-minute period, the
Independent Transmission Provider would announce the real-time energy
prices that it estimates will clear the market and match generation
with load during that upcoming period (based on the real-time bids
submitted by market participants). The Independent Transmission
Provider could settle all departures in real-time from the day-ahead
schedule using these prices announced in advance. Such an ex ante
pricing policy would provide price certainty and thereby encourage
buyers and sellers that have not submitted bids to adjust their
transactions in response to the announced price.
314. Alternatively, an ex post pricing policy could be used as an
incentive for suppliers to follow dispatch instructions. Some bidders
may not respond to the announced prices in the way suggested in their
bids. For example, a supplier stating in its bid that it would increase
its output by 50 MWh for each price increase of $5/MWh may in fact
increase its output by less than 50 MWh in response to such a price
increase. By settling at the ex ante price, the generator would be paid
the higher price despite the fact that it did not increase its output
as it had promised in its bid. An ex post pricing rule might help to
encourage bidders to respond in real time in a way consistent with
their bids. Specifically, the price used to settle real-time deviations
from day-ahead schedules could be the price-bid associated with the
energy observed ex post to be produced by the marginal supplier in the
5-minute period (but not higher than the advisory price announced ex
ante). Such an ex post price rule would encourage suppliers to supply
the full amount of energy promised in their bids.
315. We propose to adopt the ex post rule because it creates
incentives for bidders to act consistent with their bids. We seek
comment on the choice between ex post and ex ante pricing.
Other Charges for Uninstructed Deviations From Schedules
316. We seek comment on whether market participants should face
additional charges for ``uninstructed'' deviations in real time from
their schedules, i.e., for producing or taking a different amount of
energy in real time than was scheduled without permission or direction
from the Independent Transmission Provider. Uninstructed deviations
from schedules may increase the amount of regulation service or other
ancillary services that the Independent Transmission Provider must
procure, in order to reliably balance load and generation. If so, it
would be appropriate to recover the costs of these services through a
charge. We seek comment on whether the increased costs of regulation
service or ancillary services should be allocated to the entities
(buyers and sellers) that had uninstructed deviations from their
schedules since the costs were incurred to serve these entities.
Uninstructed deviations may also require the use of scarce ramping
capability within the Independent Transmission Provider's market area.
If ramping capability were used, it may be appropriate to charge for
that use. We seek comment on whether and how to establish market prices
for ramping capability. Finally, in extreme cases large uninstructed
deviations can threaten reliability of service. To discourage this type
of conduct a penalty provision may be appropriate.\153\ We seek comment
on whether the SMD Tariff should include penalty provisions for
uninstructed deviations that threaten system reliability and how such
penalty provisions should be structured.
---------------------------------------------------------------------------
\153\ This penalty would be in addition to any penalties
incurred for violating curtailment orders.
---------------------------------------------------------------------------
What Bids Should Be Eligible To Set the Energy Price
317. Strictly speaking, the marginal cost of meeting a small
increment of load would be based on the bids of suppliers whose output
can be increased, or buyers whose load can be decreased, from their
scheduled level in the hour by as little as 1 MW. Thus, for example,
the marginal cost of supplying load in an hour would not be based on
the bid of any generator that is operating in the hour solely because
of a minimum run constraint, because changes in load would not change
the output of the generator.\154\
318. However, we are concerned that by excluding generators whose
output is adjustable in increments greater than 1 MW, on an hourly
basis, from setting the energy price may not promote efficient
results.\155\ These potential inefficient results are more likely to
occur in the real-time market than in the day-ahead market.\156\
Therefore, we propose to allow generators whose output is adjustable on
an hourly basis, but only in increments greater that 1 MW, to be
eligible to set the energy price in the Real-Time Market if two
conditions are met. First, the generator's output must be needed to
meet load in the hour. That is, in the absence of the generator's
output, either load could not be fully met or a more expensive
generator would be needed to fully meet load. Second, the reason that
the generator is operating must not be a minimum run time constraint.
We also propose that any cheaper generators that are directed to reduce
their output would be paid their opportunity costs (i.e., the
difference between the applicable energy price and their energy bids)
for the amount of the output reduction. With this payment, the
generator is compensated for the legitimate opportunity cost of
following the Independent Transmission Provider's instructions.\157\
---------------------------------------------------------------------------
\154\ Also, a generator that is operating at its low operating
limit would not be able to set the market-clearing price.
\155\ When such ``lumpy'' generators are needed to meet
incremental load, it may be necessary to reduce the output of
cheaper but more flexible generators (i.e., generators whose output
can be adjusted in 1 MW increments.) For example, to meet a 30 MW
increase in load, the cheapest available generator (with a bid of
$80/MWh) may be a combustion turbine with a capacity of 50 MW that
can produce only at its maximum capacity. By operating the
combustion turbine at 50 MW, the output of a cheaper flexible
generator (with a bid of $60/MWh) would need to be reduced by 20 MW
in order to match the 30 MW increase in load with the net increase
in generated output. Once the flexible $60 generator is backed down,
incremental load would be met with output from the flexible
generator, so the marginal cost of meeting load would be $60.
However, it would not be efficient to meet the additional load
unless the load valued electricity at more than $80, the cost of the
combustion turbine.
\156\ In the real-time market, some market participants that
have not submitted bids may nevertheless adjust their production or
consumption. Thus, the rules for setting energy prices in the real-
time market should consider these possible effects on market
participants that have not submitted bids. By contrast, day-ahead
schedules are based only on bids and self-schedules submitted to the
Independent Transmission Provider, so day-ahead prices cannot result
in any unexpected changes in the day-ahead schedule.
\157\ These payments would be recovered through an uplift charge
to loads that purchase from the Independent Transmission Provider's
markets.
---------------------------------------------------------------------------
319. We seek comment on whether such lumpy generators should also
be eligible to set the energy price in the day-ahead market. Although
allowing these lumpy generators to set the energy price may have more
direct benefit in the real-time market, we are concerned about
potential negative ramifications from establishing different pricing
rules for the day-ahead and real-time markets.
b. Real-Time Ancillary Services Markets
320. As discussed earlier, Order No. 888 requires transmission
providers to offer to provide to transmission customers energy
imbalance service, regulation and frequency response, operating
reserve--spinning and operating reserve--supplemental. Under Standard
Market Design, energy
[[Page 55495]]
imbalance service would be provided through the transmission provider's
real-time energy market. The Independent Transmission Provider would
procure its expected requirements for the remaining three ancillary
services through day-ahead ancillary service markets discussed above.
321. We propose that the Independent Transmission Provider operate
a real-time ancillary services market to accommodate adjustments in the
supply of ancillary services from the day-ahead schedule. In real time,
there may be entities that can provide ancillary services more
efficiently than those that were scheduled in the day-ahead market. The
real-time market would permit such efficient substitutions. Higher-cost
suppliers scheduled in the day-ahead market would buy back their offer
to provide ancillary services at the applicable real-time price, and
other, lower-cost entities would be paid the real-time price to take
over the supply of ancillary services. In addition, the Independent
Transmission Provider may need an amount of ancillary services that
differs from the amounts procured in the day-ahead market, for several
reasons. For example, the requirements expected in the day-ahead market
may differ from actual, real-time requirements, or participants
scheduled to provide ancillary services may experience outages in real
time. Under Standard Market Design, the Independent Transmission
Provider would procure any additional ancillary services needed in real
time through the real-time ancillary service markets that it operates.
322. In the real-time market, the Independent Transmission Provider
would accept bids for each ancillary service. As in the day-ahead
market, a participant could offer the same capacity in more than one
ancillary service market. The real-time bids would contain the same
types of information as those submitted into the day-ahead ancillary
service markets, with one exception--we propose to exclude availability
bids for spinning reserves and supplemental reserves in real time. The
types of costs reflected in the availability bid to ensure that the
supplier will be available to provide these reserves are incurred in
the day-ahead time frame, not in real time.\158\ There do not appear to
be any incremental costs associated with providing these ancillary
services in real time, other than the opportunity costs of forgoing
sales in another market operated by the Independent Transmission
Provider, and these opportunity costs would be reflected in the way
that ancillary service prices are determined.\159\
---------------------------------------------------------------------------
\158\ For example, the supplier may need to commit in advance to
pay workers to staff its facility. However, the supplier would be
able to offer to supply spinning reserves and supplemental reserves
in real time if its workers were already staffing its facility, so
in real time the supplier would not incur increment costs to provide
ancillary services.
\159\ Providing regulation service, however, would typically
impose incremental out-of-pocket costs on the supplier, due to the
additional wear and tear on equipment associated with frequent
adjustments in output that regulation suppliers must make.
---------------------------------------------------------------------------
323. The Independent Transmission Provider would consider all bids
to sell ancillary services in real time and select those bids that
minimize the overall cost of procuring additional ancillary services
required in real time.
324. Based on the bids accepted in the real-time market, the
Independent Transmission Provider would establish real-time ancillary
service prices for each hour that reflect the marginal cost of each
service. All participants supplying a given type of ancillary service
in a given hour in real time (and to a given location, if there are
locational ancillary service requirements) would be paid the applicable
market clearing price.
325. Transmission customers that have not self-supplied or procured
through third parties their full assigned ancillary service requirement
would be assessed a pro rata share of the costs incurred by the
Independent Transmission Provider for procuring ancillary services in
real time.
4. Market Rules for Shortages or Emergencies
326. We believe the market rules discussed above in combination
with the market mitigation measures and the resource adequacy
requirement will result in an efficient system for matching supply and
demand under most operating conditions. However, we recognize that when
emergency situations do occur, changes may be needed to the market
rules to comply with reliability requirements. In the event of a
capacity shortage or emergency, local reliability rules and procedures
(which typically combine NERC, regional reliability council and system
operator guidelines) prescribe a series of actions that the system
operator takes to maintain reliability. For example, procurement of
reserves is reduced, typically in order of reserve quality (that is,
supplemental reserve quantities are reduced before spinning reserve
quantities). The system may be re-dispatched to adjust the location and
responsiveness of remaining reserves. System operators have also
traditionally called on emergency supplies from neighboring systems (in
the past, these emergency purchases have taken place at pre-defined
prices; increasingly, they are being made at market prices). Finally,
steps are taken for voluntary and involuntary load-shedding. States
typically approve in advance the retail curtailment plans of utilities.
327. In the markets proposed in the SMD Tariff, we envision that
with more extensive demand-side participation, the potential for these
types of capacity shortage or emergency situations will substantially
diminish. However, system emergencies may occur. The existing pro forma
tariff gives transmission providers the authority to curtail
transmission service and take any other preventive action necessary to
preserve system reliability. The SMD Tariff would continue to grant the
Independent Transmission Provider this same authority. However, the
actions taken to ensure system reliability can affect prices in the
energy and ancillary service markets. Market participants should be
aware of how these actions will affect pricing in the markets operated
by the Independent Transmission Provider. To that end, the SMD Tariff
requires Independent Transmission Providers to file proposals with the
Commission regarding the implications for market pricing of each
reliability procedure. These proposals would need to be consistent with
the resource adequacy mechanisms discussed below, but could vary to
reflect regional differences in reliability requirements. We seek
comments on what, if any, more specific requirements should be included
in the Final Rule.
G. Other Changes To Remove Undue Discrimination and Improve the
Efficiency of the Markets Under Standard Market Design
328. The existing pro forma tariff was constructed primarily to
apply to vertically integrated public utilities. It was the first step
toward competitive electric power markets since it allowed alternate
suppliers to access loads through an open access transmission tariff.
It sought to replicate the terms and conditions under which the host
public utility served its own loads. It also was the first step in
separating the generation and transmission arms of a public utility.
329. But more changes are needed to further the development of
regional competitive wholesale electric markets and assure comparable
and non-discriminatory treatment of all market participants.
Accordingly, the following revisions must be made to the pro forma
[[Page 55496]]
tariff to change the market rules in ways that will improve the
efficiency of wholesale electric markets.
1. Capacity Benefit Margin
330. Capacity Benefit Margin is the set-aside of transmission
capability by a transmission provider to ensure the ability to import
external resources to meet generation reliability requirements or in
case of a generation capacity deficiency. During the Commission's
outreach process, many commenters asserted that Capacity Benefit Margin
ties up valuable transfer capability without a specific reservation and
payment by the customers who receive the benefit of the set-aside. The
subsidy occurs because, while part of the transfer capability is
withheld from the market as Capacity Benefit Margin, the wholesale
transmission customers using the system pay the entire transmission
cost (including that of the Capacity Benefit Margin) through their
transmission charges, thus subsidizing the Capacity Benefit Margin
beneficiaries. The use of a Capacity Benefit Margin has also been
regularly challenged on the grounds that the host transmission provider
is withholding transfer capability under the guise of Capacity Benefit
Margin in order to thwart competition.
331. We propose to standardize the treatment of Capacity Benefit
Margin to ensure that (1) only customers benefitting from it pay for
it, and (2) transfer capability needed to access resources on a
neighboring system is treated consistent with all other portions of the
transmission grid. Thus, an Independent Transmission Provider itself
would not be permitted to set aside transfer capability for generation
reliability reasons. Rather, a load-serving entity wanting access to
resources on a neighboring transmission system to meet its resource
adequacy requirement should instead acquire Congestion Revenue Rights
from the interface to its load to ensure that access. This will free up
transfer capability now unavailable to wholesale transmission customers
and prevent cross-subsidization of transmission customers that serve
load within the Independent Transmission Provider's service area by
point-to-point transmission system users.\160\
---------------------------------------------------------------------------
\160\ To the extent that an Independent Transmission Provider's
load ratio share access charge calculation does not pick up this
reservation, the amount of interface capability can be imputed and
added to the customer's peak day amount.
---------------------------------------------------------------------------
332. This prohibition of the generic set-aside of transfer
capability by the Independent Transmission Provider for generation
reliability reasons does not apply to an Independent Transmission
Provider's responsibility to set aside transfer capability to ensure
transmission reliability (e.g., to ensure that a line can take up the
power flows it must absorb if a parallel line should go out of service
or other uncertainties in system conditions arise). Such a set-aside is
called Transmission Reliability Margin and must be consistent with good
utility practice and should not be implemented in a way that favors
particular transmission customers (e.g., by release of the set-aside
capability for use by native load).
2. Regional and Independent Calculation of Available Transfer
Capability, Performance of Facilities Studies and OASIS
333. The Commission has found specific instances of abuse by
transmission providers regarding the Available Transfer Capability
calculation process and delays in the completion of transmission
facilities studies.\161\ There are obvious incentives for a vertically
integrated transmission provider to favor its own generation by
delaying facilities studies or manipulating the Available Transfer
Capability calculations or postings on its OASIS. Under Standard Market
Design, calculations of transmission capability and the performance of
facilities studies for transmission expansions must be performed by an
independent entity to reduce the opportunity for preferential treatment
by the transmission provider.
---------------------------------------------------------------------------
\161\ See Section III and Appendix C.
---------------------------------------------------------------------------
334. More broadly, the SMD Tariff must recognize the regional
nature of today's energy markets. Transmission capabilities must be
calculated not for a single utility's service territory, but regionally
to encompass existing trading patterns and power flows, particularly
parallel path flows on neighboring systems. All transmission providers
that are not part of a Commission-approved RTO must contract with an
independent entity to perform transmission capability calculations on a
regional basis. Likewise, we propose to require a common OASIS for the
region.
3. Regional Planning Process
335. Competitive and reliable regional power markets require
adequate transmission infrastructure to allow geographically broad
supply choices and minimize the complications created by loop flow. The
recent DOE National Grid Study documented the problems resulting from
recent under-investment in transmission infrastructure and identified a
number of causes. Among the causes were the lack of regional planning
and coordination of transmission needs and siting issues.
336. Transmission planning and expansion have generally been
performed for a single control area rather than on a regional basis.
This yields sub-optimal solutions, as individual transmission providers
consider power flows across a limited area and do not adequately
consider entire markets. Parallel path flows that occur on neighboring
systems may make the construction of specific facilities less cost-
effective than a regional solution. This effect can be properly
considered by performing transmission planning and expansion on a
regional basis. Moreover, facilities that, if constructed in one system
would be the optimal solution for a neighboring system, might never be
considered under a single control area-based planning model.
337. Implementation of Standard Market Design will only increase
the importance of examining these issues on a regional basis. More open
and transparent markets will enable customers to purchase from distant
suppliers, increasing use of the grid. Locational marginal prices that
result from the spot markets operated by an Independent Transmission
Provider would signal to all market participants the value of
additional supply and demand response at particular locations. Based on
these prices over time, market participants will be able to decide
whether additional investment--in transmission or generation facilities
or demand response--is warranted. The ability of individual market
participants to see the economics of possible solutions and make
market-driven decisions concerning the addition of infrastructure is
the fundamental mechanism that induces efficient investment under
Standard Market Design. The policy relies primarily on a ``ground-up''
planning process that encourages construction by private companies yet
also recognizes the need for a regional evaluation process for loop
flow effects and cost-effectiveness. It is neutral with respect to the
type of investment market participants may make in response to these
price signals. However, due to loop flow, all system modifications
would need to be coordinated through a regional process and would have
to meet any criteria needed to maintain reliability and stability, and
assure that existing customer rights are not impaired.
338. Given the need for transmission investment in much of the
country and the time it will take to implement Standard Market Design
and for
[[Page 55497]]
investors to observe and respond to price signals, we propose that a
regional planning process be instituted within six months of the
effective date of the Final Rule. This process should be designed to
identify beneficial transmission needed for both reliability and
economic reasons to support regional markets and reduce the effects of
generation concentration. The regional planning process should allow
the market to respond to those identified needs.
339. A critical piece of the transmission planning process is
state-level siting decisions. We note a recent National Governors'
Association report that recommends Multi-State Entities to facilitate
regional transmission planning decisions.\162\ Multi-State Entities,
along with an open regional planning process, would preserve the
states' role in siting decisions, while promoting regional solutions. A
Multi-State Entity could be an important component of the regional
planning process.
---------------------------------------------------------------------------
\162\ See Interstate Strategies for Transmission Planning and
Expansion, National Governors' Association, posted on July 18, 2002,
available in <http://www.nga.org/center/divisions/1,1188,C--ISSUE--
BRIEF[caret]D--4110,0.html.
---------------------------------------------------------------------------
340. Certain areas of the country and organizations already have
proposals or processes to consider regional planning or development of
regional markets. Building off of these existing efforts will help
facilitate the development of a regional planning process in the near
term. We emphasize that a planning area need not coincide with the
geographic area of a Commission-approved RTO or Independent
Transmission Provider required by this rule. Also, because of the
interrelationships between Canadian and U.S. energy markets, we
encourage participation by Canadian entities and provincial authorities
in the regional planning process.
341. Current processes such as the Committee on Regional Electric
Power Cooperation in the West provide for state and provincial advice
in the planning across the entire Western grid. Therefore, we propose
to use the area covered by Western Electricity Coordinating Council
(WECC) that encompasses the geographic area covered by the Western Grid
for regional planning purposes.
342. In the Eastern Interconnection there have been several efforts
at developing regional wholesale electricity markets that we propose to
build on for the regional planning process. PJM and MISO developed a
Memorandum of Cooperation dated May 9, 2002 that commits to develop a
joint and common wholesale electric market for PJM, MISO, and SPP.
Consequently, we propose that the area covered by these organizations
would also be a regional planning area.
343. Similarly, New York ISO and ISO-New England are currently
pursuing discussions on the merger of these two organizations into a
Northeast RTO. Both are also members of the Northeast Power
Coordinating Council which has recently conducted studies of
transmission needs in the region.\163\ We propose to build on these
efforts and use the area covered by these organizations as a planning
area.
---------------------------------------------------------------------------
\163\ Northeast Power Coordinating Council Collaborative
Planning Initiative Phase I issued March 13, 2002.
---------------------------------------------------------------------------
344. Finally, we recognize that there has been ongoing discussion
development of regional markets in the Southeast. SETrans Regional
Transmission Organization proposes to encompass a broad area in the
Southeast. The Tennessee Valley Authority (TVA) has signed a Memorandum
of Understanding with Southern Companies and Entergy, two sponsors of
SETrans, to work together to develop coordination agreements.
Additionally, the SETrans and GridSouth Transco, LLC parties signed a
Memorandum of Understanding in January 2002 calling for similar
regional coordination. Thus we propose to build on these efforts and
propose a Southeast planning area composed of the Southeastern Electric
Reliability Council and the Florida Reliability Coordinating Council.
345. We propose that all public utilities that own, control, or
operate transmission facilities must participate in a regional planning
process for the planning areas discussed above. We propose that this
process start within six months after the effective date of the Final
Rule and that the first regional transmission plan be completed within
twelve months after the effective date of the Final Rule. Reliance on
these existing regional efforts should facilitate the start-up of the
regional planning process before Standard Market Design is implemented
and all areas have Independent Transmission Providers operating
transmission facilities.
346. After Standard Market Design is fully implemented, we believe
the regional planning process will change as Independent Transmission
Providers play a greater role in that process. There will still remain
a significant need for a regional planning process to supplement
private ``ground up'' investment decisions. The regional planning
process is intended to supplement these private investment decisions,
not supplant them. The regional planning process must provide a review
of all proposed projects to assess whether the project would create
loop flow issues that must be resolved on a regional basis. In
addition, because of the externalities involved, there may be no
private investment sponsor for some projects that would benefit the
region. Private investment decisions in response to prices may not
result in adequate expansions for two reasons. First, private parties
may not be eligible to ask the state to exercise its eminent domain
rights. Second, some needed and beneficial expansions may not create
enough identifiable financial benefits to compensate private investors
adequately, so those projects will not be built under a system that
relies solely on private investment to expand the grid. A regional
planning process can identify both the projects that would benefit the
planning area and potential alternatives in a fair and unbiased manner.
Additionally, a regional planning process, would evaluate the benefits
of alternative proposals and provide an independent assessment of which
projects are the most cost effective and/or have the least
environmental impact.
347. To complement private investment initiatives, we propose that
Independent Transmission Providers establish a mechanism for regional
transmission planning and expansion guided by the following principles.
First, the planning process should identify all expansion needs on the
system, including both reliability and economic needs (e.g., to reduce
congestion). The planning process should leave open the question of how
and by whom those needs should be met, without favoring one solution
(whether it is transmission, generation or demand response) over
another. The planning process should be open to all industry segments.
Additionally, all entities could propose projects. As long as the
project did not make existing Congestion Revenue Rights infeasible due
to loop flow problems, the entity would be free to complete the project
as long as it is willing to assume any market or regulatory risk.
However, to the extent the entity sought to roll-in the costs of the
facilities, the rate treatment should be reviewed through the planning
process.
348. Second, an Independent Transmission Provider should have the
responsibility to issue requests for proposals when the planning
process determines that additional resources are needed to serve the
regional market. Parties may respond with proposals to expand the grid,
add generation (including distributed generation), or
[[Page 55498]]
implement demand response.\164\ The Independent Transmission Provider
would approve transmission expansions that would be paid for by all
customers only when planned private investments are judged to be
inadequate to meet the reliability and market needs of the region. If
the bidding process fails to produce a satisfactory outcome, such that
the Independent Transmission Provider determines that additional
facilities are needed, the affected transmission owner(s) would be
required to expand or upgrade the transmission system.\165\
---------------------------------------------------------------------------
\164\ We recognize that the states have the ultimate authority
over siting.
\165\ See existing pro forma tariff Secs. 13.5 and 15.4
(transmission provider required to expand its transmission system if
transmission customer agrees to compensate the transmission
provider). This requirement extends to the transmission owners.
---------------------------------------------------------------------------
349. Finally, the Independent Transmission Provider would act as a
clearinghouse for proposed projects. It could identify separate
projects that could be constructed at a lower cost if the projects were
combined. Also, if there are alternative projects that have been
proposed, the Independent Transmission Provider could evaluate the
relative advantages of the alternative projects.
350. This approach to regional planning and expansion is fully
consistent with Standard Market Design's goal of inducing efficient
investment by relying primarily on price signals and independently
administered Congestion Revenue Rights. At the same time, it recognizes
that private investment decisions may not be fully adequate in all
cases because of eminent domain and the possibility that private
benefits of investment could be significantly less than social
benefits. The planning process would have a regional scope, permit
direct competition among all types of investment, include all market
participants equally, and minimize the need to rely on eminent domain
and the support of captive customers. Because existing transmission
owners are the transmission builder of last resort, it also respects
the reality that not all states allow non-traditional utilities to
build in their state or to obtain eminent domain, thus creating a legal
barrier to entry.
4. Modular Software Design
351. Software and data issues have become an important part of the
market design and changes to market design. On many occasions over the
past several years, market designs and improvements have been delayed
or even abandoned due to software constraints or software development
costs. Software and data systems inherited from the old structure are
often idiosyncratic, making changes and seams issues more difficult
than they should be. Market participants often find software to be
impenetrable ``black boxes.'' Software development and modifications
have become expensive and software ``wheels'' are being reinvented.
Consequently, the software used to implement the Standard Market
Design's real-time and day-ahead markets will be a critical element in
the feasibility and success of Standard Market Design.
352. The Standard Market Design software should have the following
characteristics: transparency (the ability to understand what the
software does), testability (the ability to understand and compare
performance) and modularity (the ability to change software modules
without changing other software). Transparency, modularity and
testability help break down entry barriers and allow for competition in
software development. Modularity requires standard interfaces (well-
defined data inputs and outputs and ease of access). Since we expect
Standard Market Design to evolve over time and wholesale markets to
grow, the underlying software must be able to accommodate change.
Scalability, security and robustness are desirable design features.
353. All market and operations software approximates the actual
operation of the system. However, computational and feasibility issues
are not well understood. Issues include performance, AC vs. DC models
and consistency if both are used. Unit commitment models use different
heuristics that were not important in the old vertical structure, but
can be very important for new demand and supply entrants in a
decentralized market. To instill confidence in the software, testing,
validation and evaluation should be a part of an open process.
354. We propose to require that the software meet the
characteristics set forth above and that the input and output data
systems and other Electronic Data Interchange be standardized in a
common data model including a data dictionary (glossary and/or data
definitions) and common network description. We seek comment on the
following questions.
355. The Commission held a conference on July 18, 2002, to discuss
the operational data and software needed to implement Standard Market
Design and large regional wholesale markets, following an earlier
conference on software issues. Among the topics discussed were market
operational software capabilities, software standardization, ISO
experiences with implementing software, cyber-security and the need to
achieve some standardization within the electric market and grid
operations software modules across vendors.
356. The conference established that for most applications,
software does not appear to be a binding constraint on the size of RTOs
or the implementation of Standard Market Design. Participants noted
that the computational algorithms inside the models are continually
improving, as is the speed of the processors used to solve the models,
so it is reasonable to expect that software and associated hardware
needs should keep pace with market span.
357. The Commission's goal is to assure that the best software is
available for use in the nation's wholesale markets. This can best be
attained by promoting competition among vendors, in a way that assures
that no vendor comes to ``own'' a market niche or impose barriers to
entry by new software companies with innovative analytical approaches.
358. Many vendors have particular areas of expertise and their
software is often integrated with other software in complete software
systems. We propose to encourage the development of ``plug-and-play''
software designs so that the best modules can be integrated into
complete market operational systems for Independent Transmission
Providers. To accomplish this we need to standardize data transfer
between modules. Participants at the conference proposed two ways of
accomplishing this--open systems and standardization. The open systems
approach would leave it to each vendor to develop and publish the
interface to the next module in the system. The standardization
approach would define a set of minimum specific standard functions for
each software module and specify the interfaces to be used between
modules. We believe that the standardization approach is best suited to
the close time frame needed for Standard Market Design implementation,
and invite comment on the best process to develop these standards--
should we use the evolving NAESB process or forums set up by the
Electric Power Research Institute for this purpose, or use another
approach?
359. The discussion of a suite of benchmark problems to test
software illustrated the importance of benchmarking to facilitate
testing and comparison of candidate software with respect to solution
outcomes and processing time. We therefore encourage
[[Page 55499]]
the industry to develop such a suite of benchmark or test problems.
360. As a follow-up to the July 18, 2002 Standard Market Design
software conference, the Commission will hold another conference on
these topics on October 3, 2002. This conference will focus
particularly and in detail on what process or body should be used to
set standards for data standardization for inputs and outputs to
software modules; whether the standards already developed by the
Ontario Independent Market Operator for this purpose might be
applicable for United States markets;\166\ and how to proceed with the
development of test problems for evaluating and comparing software
modules.

5. Transmission Facilities That Must Be Under the Control of an
Independent Transmission Provider
361. In a variety of public forums, including RTO conferences and
comments to RTO proceedings, much uncertainty has been expressed
concerning two questions: which facilities belong under the control of
the RTO; and which customer-owned transmission facilities that are
turned over to RTO control are entitled to a credit? \167\ In some
instances, the dispute centers on whether the facilities are
integrated. Other disputes involve the voltage level at which a
facility is determined to be transmission. Under this proposed rule,
the question becomes which transmission facilities must be under the
control or an Independent Transmission Provider, be it an RTO or not.
---------------------------------------------------------------------------
\167\ See, e.g., City of Vernon, California, 93 FERC [para]
61,103 (2000), 94 FERC [para]
61,344 and 61,148 (2001); 95 FERC
[para]
61,274 (2001); and 96 FERC [para] 61,312 (2001).
---------------------------------------------------------------------------
a. Before Order No. 888
362. Before Order No. 888, much of the industry consisted of
vertically integrated investor-owned utilities (IOUs) that, for the
most part, provided a single service--bundled requirements power--to
retail and wholesale customers alike. The classification of delivery
facilities between transmission and distribution came up only in a
ratemaking context. Because wholesale requirements customers purchased
bulk power, they often did not require service over distribution
facilities. Often, only a stepdown substation or a feeder line was
involved. For those few stand-alone transmission services that an IOU
might provide, the cost allocation issue was the same. The Commission
approached this allocation issue by defining an integrated transmission
grid as those facilities that operate in a single cohesive fashion to
deliver bulk power and allocating wholesale (and stand-alone
transmission customers) a proportional share of the embedded costs of
those facilities on a rolled-in basis with postage stamp pricing.
363. Infrequently, the Commission would consider rate treatments
premised on the distinction between transmission and subtransmission
(high and low voltage transmission). If there were delivery facilities
(transmission or distribution) that were not part of the integrated
grid, but were used by a specific wholesale customer (e.g., radial tap
line or stepdown substation), the Commission would allow the direct
assignment of those facility costs in wholesale rates.
364. These issues were discussed at length in Commission cases in
the 1970s when IOUs attempted to bifurcate the pricing (effectively
pancaking) and thereby increase their wholesale revenues. Customers, on
the other hand, wanted to classify facilities as transmission and
thereby decrease their delivered energy charges by only paying one
charge for these facilities. While the issue was often framed as a
transmission/distribution issue, it was mostly a battle over utilities
trying to pancake rates (through charging a rolled-in rate plus a
direct assignment charge) for transmission facilities or facilities
that provided both transmission and distribution functions (dual-
function facilities).
b. Order No. 888
365. Order No. 888 did not require a change in traditional rate
treatments. However, since the Commission issued its open access rules,
a number of utilities have proposed subclassifications of transmission,
e.g., transmission and subtransmission. Protestors (generally
transmission-dependent utilities) have argued that this rate treatment
favors transmission users that are connected to the transmission system
at higher voltages (i.e., the transmission owners' own generation) by
reducing their rates for open access transmission service (because they
pay only the high-voltage charge) and that reclassification is just
another way to pancake rates and increase charges to low-voltage users.
During the Commission's public outreach, commenters pointed to such
splits as the pool transmission facilities (PTF)/non-pool transmission
facilities in ISO New England as an example. This is not a consistent
classification of pool transmission facilities and non-pool
transmission facilities among transmission owners in New England. A
generator located on a lower voltage portion of the ISO's grid must pay
an additional non-PTF charge to access the New England market, but
other, generators do not, putting the first generator at a competitive
disadvantage.
366. The issue of transmission/distribution classification in Order
No. 888 was in the context of unbundled retail transmission service and
the Federal Power Act's legal jurisdiction distinction between
``transmission'' facilities (subject to Commission jurisdiction) and
``local distribution'' facilities (subject to state or local
jurisdiction). To determine what facilities would be under Commission
jurisdiction for purposes of the Order No. 888 open access requirements
and what facilities would remain subject to state jurisdiction for
purposes of retail stranded cost adders or other retail regulatory
purposes, the Commission developed a seven factor test to determine
what facilities are transmission facilities and what facilities are
local distribution facilities.\168\ With respect to the seven factor
test, the Commission also stated that it would defer to the state
commission's findings as to what facilities constitute local
distribution facilities if the state's determination was consistent
with our comparability principles. In addition, dual purpose
facilities, i.e., those used both for transmission or wholesale sales
and for local distribution, would fall under the Commission's
jurisdiction. To the extent use of particular facilities changed over
time, the Commission would revisit these determinations. The Supreme
Court upheld these determinations upon appellate review.\169\
c. Test for Transmission Facilities
---------------------------------------------------------------------------
\168\ Order 888 at 31,771.
\169\ New York v. FERC, 122 S. Ct. 1012.
---------------------------------------------------------------------------
367. Order No. 888's seven factor test was designed to determine
the local distribution component of an unbundled retail sale. The test
did not exist prior to Order No. 888 and in fact was created to do
something the Commission had never done before--identify local (retail)
distribution facilities. Thus, the test identifies all facilities that
are not local distribution facilities. We propose that this is the
appropriate starting point for determining which facilities belong
under the control of an Independent Transmission Provider. To the
extent that a transmission owner or Independent Transmission Provider
[[Page 55500]]
believes that certain facilities should not be under the Independent
Transmission Provider's control, the Independent Transmission Provider
may request an exception to this presumptive determination.
368. This proposed test focuses on the presumption that, if a
facility is transmission, it belongs under the control of the
Independent Transmission Provider. Thus, once a determination is made
with the seven factor test, there would be no need for an additional
review under the Commission's previous integrated facilities test. In
MidAmerican Energy Company,\170\ the Commission explained that the
Commission's determination of which facilities are transmission is
fluid and dependent on actual use of the facilities:
---------------------------------------------------------------------------
\170\ 90 FERC [para]
61,105 (2000).
Although we are accepting the state commissions' classification,
we reiterate our finding in Order No. 888 that to the extent that
any facilities, regardless of their original nominal classification,
in fact, prove to be used by public utilities to provide
transmission service in interstate commerce in order to deliver
power and energy to wholesale purchasers, such facilities become
subject to this Commission's jurisdiction and review.\171\ In
addition, the rates, terms and conditions of all wholesale and
unbundled retail transmission service provided by public utilities
in interstate commerce are subject to this Commission's jurisdiction
and review.\172\
---------------------------------------------------------------------------
\171\ In Order No. 888, the Commission explained that ``a public
utility's facilities used to deliver electric energy to a wholesale
purchaser, whether labeled ``transmission,'' ``distribution,'' or
``local distribution,'' are subject to the Commission's exclusive
jurisdiction under sections 205 and 206 of the FPA.'' Order No. 888
at 31,969; accord Nevada Power Company, 88 FERC [para]
61,234 at
61,768 (1999).
\172\ Transmission service in interstate commerce by public
utilities, including the rates, terms and conditions for such
service, remains within this Commission's exclusive jurisdiction. 16
U.S.C. 824, 824d, 824e (1994). See generally Order No. 888-A at
30,339-41.
---------------------------------------------------------------------------
Further, our deference in this proceeding does not affect the
Commission's separate determination of what facilities must be under
the operational control of RTOs, including ISOs and Transcos.\173\
The Commission will make this latter determination, taking into
account the seven factors formulated for purposes of determining
jurisdiction as set forth in Order No. 888,\174\ the ISO principles
set forth in Order No. 888,\175\ and the principles set forth in the
RTO Final Rule.\176\
---------------------------------------------------------------------------
\173\ Which facilities will or will not be under an RTO's
operational control also does not predetermine transmission pricing,
cost allocation, or rate design determinations at either a state
commission or at this Commission.

---------------------------------------------------------------------------
We note that the determination of which facilities are under the
operational control of the Independent Transmission Provider does not
dictate transmission pricing.\177\
---------------------------------------------------------------------------
\177\ As noted in MidAmerican, present ISO agreements obligate
transmission owners to provide access over facilities that are not
under the control of the ISO if those facilities are needed to
provide wholesale transmission service regardless of ownership or
whether those facilities are labeled transmission, distribution
(i.e., distribution facilities other than local distribution), or
local distribution. The same holds for Independent Transmission
Providers.
---------------------------------------------------------------------------
369. We request comment whether, either in addition to or in lieu
of the seven factor test, the Commission should use a bright line
voltage test (e.g., 69 kV) to determine which facilities are placed
under the control of the Independent Transmission Provider. If so, we
seek comment on the bright line, whether we should allow regional
variation, and how transmission facilities that are not placed under
the control of the Independent Transmission Provider's tariff are
treated with respect to open access and rates.
H. Transition to Single Transmission Tariff
370. This section discusses the transition process that will be
used to move from the existing pro forma tariff to the SMD Tariff.
First, we discuss the provisions of the revised tariff that remain the
same as those in the existing pro forma tariff, but may change based on
the comments received in response to our questions. Second, we discuss
the provisions we propose to change. When Standard Market Design is
implemented, the revised tariff would apply to nearly all transmission
services on the system. All customers would receive the same quality
and quantity of service they currently receive. Customers currently
taking transmission service under an open access transmission tariff
would continue to do so, but now would be served under the new Network
Access Service under a revised open access transmission tariff. Bundled
retail customers would continue to receive service from their existing
load-serving entity; however, the load-serving entity would be required
to take service under the new Network Access Service pro forma tariff
in order to serve those retail customers. Similarly, while wholesale
customers with pre-Order No. 888 contracts would be given the
opportunity to convert to the new transmission service under a revised
open access transmission tariff, if they choose not to do so, the
transmission owner that provides service under the pre-888 contract
would be required to take service under the new Network Access Service
pro forma tariff in order to meet its contractual obligations to serve
those customers.
371. Standard Market Design is intended to cure undue
discrimination, more efficiently use the transmission grid and give
customers additional options. To help ensure that the transition
process satisfies these objectives, the proposed rule would allow
certain regional flexibility in the implementation process to the SMD
Tariff. In particular, the regions would have flexibility in converting
the rights of existing customers to Congestion Revenue Rights or
auction revenues under the new tariff. Also, the regions would have
flexibility in establishing the rate design for the new Independent
Transmission Providers. It is anticipated that the state
representatives, through the Regional State Advisory Committees
discussed in Section IV.K., will play an active role in these regional
decisions.
1. Treatment of Customers Under Existing Wholesale Contracts
372. When the Commission issued Order No. 888 it faced the issue of
what to do with existing contracts. The Commission decided that it
would not generically abrogate existing requirements and transmission
contracts, but that under all post-Order No. 888 contracts were to
conform to the Order No. 888 pro forma tariff.
373. Similarly, we propose not to abrogate existing pre-Order No.
888 contracts. On a nationwide basis, these contracts should represent
a relatively small portion of the total load and should be able to be
accommodated within the Standard Market Design.\178\ The customers with
these contracts will be able to convert these existing contracts,
consistent with their contract terms, to the new Network Access Service
upon implementation of Standard Market Design. However, as discussed
below, if customers choose not to convert to the new service, the
transmission owner would be required to take service under the new
tariff in order to meet its contractual obligations to serve the pre-
Order No. 888 contract customers.
---------------------------------------------------------------------------
\178\ It appears that these contracts would be less than 10
percent of total load on a nationwide basis based on data from Form
No. 1 filings by public utilities for calendar year 2000.
---------------------------------------------------------------------------
374. If pre-Order No. 888 contracts remain in effect, the
contracting transmission owner would be required to take service from
the Independent Transmission Provider in order to serve its existing
wholesale power or
