I. Market
Power Mitigation and Monitoring In Markets Operated By
The
Independent Transmission Provider
1.
Principles and Objectives
1. In a
structurally competitive market, one with many buyers and sellers who cannot
influence price, the market can assure an overall efficient outcome where
prices indicate the value of additional supplies and conservation. The development of structurally competitive
markets is the Commission's long-term goal.
However, at this stage of the industry's evolution, wholesale electric
markets are not yet structurally competitive in all respects. The two significant structural flaws are the
lack of price-responsive demand and generation concentration in
transmission-constrained load pockets.
Given these structural defects, the Commission cannot rely on the
interaction of supply and demand in all instances to ensure that prices are
competitive and thus just and reasonable.
2. Cost-of-service
regulation is not effective for spot market pricing of commodities such as
electricity. In the past, customers
were served by a monopoly supplier under cost-of-service rates, in which the
fixed and variable costs of a company’s generation portfolio were allocated
over the expected hours of service to determine a cost per kWh. But today, the power needs of load-serving
entities are met through a mix of sources, including the companies' generation
portfolios, and long-term and spot market purchases from a variety of sellers,
including independent producers and marketers.
These do not match the long-term arrangements needed for cost-of-service
regulation. In this competitive
context, cost-of-service regulation designed for long-term cost recovery is not
well suited for determining appropriate spot market prices. When applied to spot markets,
cost-of-service regulation blunts price signals and leads to inefficient
investment and consumption decisions which over the long run increase costs for
all customers.
3. When markets
do not produce competitive outcomes, the Commission must use new regulatory
tools to produce just and reasonable results.
We propose new market power mitigation measures to deal with the
consequences of major structural defects in wholesale electric markets, by
approximating the outcomes that a competitive market would produce. These measures should function in markets
that are not workably competitive, but not inhibit market operation in more
competitive markets. Effective market
monitoring and market power mitigation are critical elements of the
Commission's plan to create and sustain competitive regional bulk power
markets. Therefore, the Commission
proposes rules for the spot markets to be operated by the Independent
Transmission Provider to mitigate market power.
4. Market power
is the ability to raise price above the competitive level.195
This can be accomplished if the generator can withhold physical power
(physical withholding) or cause physical power to be withheld through inflated
bids (economic withholding).196 Competitive prices over
the long run should recover both the fixed and variable costs of efficient
generating units. The challenge for
market power mitigation on the supply side is to assure that it allows
long-term competitive prices, which allows the opportunity to recover the fixed
costs of the investment as well as the short-term variable costs of producing
electricity. If some degree of scarcity
pricing is not allowed, and generation only recovers short-term marginal costs,
then some generators needed for reliability could fail to recover their full
costs and may be retired. Worse yet,
prices could be held so low that investors decline to invest in needed
generation, transmission and demand-side projects because they do not see a
reasonable expectation of recovering their costs.
5. The market
power mitigation measures proposed here are designed to address the major
structural defects in wholesale electric markets. The major structural defect on the demand side is the lack of
price-responsive demand; when customers cannot respond to high prices by
lowering their consumption, they cannot discipline price increases from
suppliers. Absent demand response,
market prices will reflect suppliers’ bids alone, so we cannot rely on market
prices to ration scarce supplies in all situations. Therefore, the market power mitigation needs to compensate for
the lack of price-responsive demand in the market.
6. On the
supply-side, structural problems tend to be more location-specific and
time-dependent. For example, binding
and sometimes unpredictable transmission constraints may restrict competitive
alternatives and create opportunities for some sellers to increase prices above
a competitive level, at least for any seller that knows some of its output will
be required to meet load reliably. This
problem is often described as a load pocket problem. In some load pockets, a specific generator may be identified as
needed for reliability, which gives it a local monopoly.197
In other situations without severe constraints, the geographic market
may be broader but if little generation divestiture or entry by non-affiliated
generators has occurred, concentration of ownership may remain high. Market power mitigation needs to mitigate
local market power, whether it arises because of a load pocket, transmission
constraints, or ownership concentration.
7. To be
effective, market power mitigation measures must be applied before the fact,
since remedies after the withholding has occurred are disruptive to the market
and increase regulatory risk to its participants, which increases costs to
customers.
8. In sum, the
challenge in developing an effective market power mitigation plan is to design
a plan that allows markets to function where they are competitive and, where
they are not, uses market mechanisms to facilitate the transition to
competitive markets. Market mechanisms
can be used to approximate the outcomes that a competitive market would produce
to provide the price signals for efficient investment and demand response. Because of the characteristics of
electricity (it can be stored only in limited instances – pumped storage,
compressed air, batteries) and the electric grid (flows follow the path of
least resistance), even in regions where markets are generally competitive,
transmission constraints may create non-competitive conditions during certain
hours. In addition, when market power
exists, the market power mitigation plan should be calibrated so that it does
not inefficiently suppress prices, or mask scarcity prices, providing the wrong
economic signals for efficient investment or demand response.
2.
Overview of the Market Power
Mitigation Measures
9. The
Commission proposes a market power mitigation plan composed of three mandatory
components that are specifically tailored to the structural flaws in the
wholesale electric markets and a voluntary fourth measure that could apply in
unusual market conditions to assure that the high prices are not the result of
market power.
10. The
first measure addresses the local market power problem and is similar in
concept to the reliability must run agreements that exist in the ISOs
today. The market monitor will identify
certain conditions in which certain generators are in concentrated geographic
markets created by transmission congestion or reliability needs of the
grid. These would include units needed
to run to support the reliable operation of the grid or a set of units owned by
a small number of companies. At those
times, those units will have localized market power so that when they are
required to provide their energy or ancillary services to the grid their bids
into the market should be capped.198 The conditions when their
power must be supplied to the grid (a must-offer obligation) and the bid cap to
apply would be specified in their participating generator agreement with the
Independent Transmission Provider.
11. The second component, a safety-net bid cap
such as the $1000 per megawatt-hour cap currently used in Northeast markets and
Texas, addresses the lack of price-responsive demand. Sellers could freely offer any amount of energy to the spot
markets constrained only by the safety-net bid cap. The safety-net bid cap should allow markets to produce prices
that reflect some (and perhaps a significant) amount of scarcity when shortages
of reserves or power exist. But absent
demand response, it sets an outer bound on suppliers’ ability to exercise
economic withholding.
12. The
third component of the market power mitigation plan is the resource adequacy
requirement discussed in Section J. The
resource adequacy requirement does not directly prevent withholding, but by
expanding the resource alternatives it diminishes the incentive and the ability
of suppliers to practice and profit from either physical or economic
withholding.
13. While
it is clear that the first three measures must be part of the Standard Market
Design market power mitigation plan, there may be market conditions in which a
fourth measure is needed. The fourth
mitigation measure would deal with situations when non-competitive conditions
may exist, by examining and possibly limiting bids from individual suppliers
into the day-ahead and real-time spot markets if those bids are high due to
withholding rather than scarcity.
Exercise of this mitigation could be triggered by predetermined
conditions or triggers (such as a sustained period of prices significantly
above competitive levels), or by significant infrastructure problems in the
market (e.g., sustained tight reserve conditions, as might be due to
drought). This mechanism is like the
Automatic Mitigation Procedure (AMP) used by the New York ISO, and adopted
recently for the California ISO. This
mechanism would not be required for every region but may be adopted if the
market monitor's analysis determines this measure is needed.
14. The
implementation of the market power mitigation plan summarized above and
described in more detail below will rely on the results of an initial
competitive market analysis by the Independent Transmission Provider's market
monitor in each region. This will
identify at the outset the persistent load pockets or other conditions that
create local market power. This
analysis will be filed with the Commission as part of the implementation
process for Standard Market Design and subject to comment from all interested
parties. After Commission review, it
will form the basis for the mitigation measures that are applied by the
Independent Transmission Provider. It
then will be updated annually to review the continuing effectiveness of the
market power mitigation.
15. The
market power mitigation measures proposed rely principally on mitigating market
power in spot markets. Mitigation would
only apply to products traded in the spot markets operated by the Independent
Transmission Provider, not to products traded under bilateral contracts outside
the Independent Transmission Provider’s spot markets. This is the least intrusive framework for market power mitigation
but at the same time provides very effective protection against market power.
16. Although power and operating reserves
purchased in the organized spot market are only a small percentage of total
purchases, mitigating the organized spot market is an effective way of
mitigating market power generally.199 Bilateral contracts
generally reflect buyer and seller expectations of prices in spot markets. Therefore, market power mitigation in the
organized spot market will effectively discipline market power in bilateral
markets as well.200 However, if spot market
prices are over-mitigated, it may weaken incentives for buyers to contract in
bilateral markets and expose spot market prices to greater price
volatility. Regular reassessment of
the market power mitigation practices can prevent this outcome, and, as
discussed infra, the market monitor will be required to annually
reassess the effectiveness of the market power mitigation.
3. Market
Power Mitigation For Local Market Power
17. Local
market power principally arises either from the concentration of generator
ownership within a load pocket, or the need for local units to operate to assure
system reliability and stability within the load pocket. Local market power can arise from both
persistent and foreseeable congestion, or from sporadic transmission
congestion. Although local market power
can arise from these different conditions, the mitigation method proposed here
can be effective at mitigating the local market power regardless of how it
arises.
18. In the existing ISOs in California and the
Northeast, participating generator agreements are used to set out the operating
terms, conditions and obligations concerning the dispatch of a generating unit,
serving principally a reliability purpose.
Under the Standard Market Design pro forma tariff all
generators dispatched by the Independent Transmission Provider would enter into
a participating generator agreement.201 Standard Market Design
will require these participating generator agreements to include provisions to
mitigate local market power.
19. The
participating generator agreements, which would be filed with the Commission,
would identify the non-competitive conditions when the generator with local
market power would be required to offer its energy either by scheduling a
bilateral transaction or by offering
all available energy to the spot markets. This would be a must-offer requirement. The requirement would apply when the generator's power is needed
to maintain the reliable operation of the grid, and also when there are
insufficient competitive alternatives.
The participating generator agreement would specify the conditions that
would give rise to a generator's must-offer requirement, and would also specify
bid caps that would apply when the generator was required to bid into the
day-ahead and real-time markets. In
non-competitive conditions, the generator's bids could not exceed the capped
values. Although the participating
generator agreement may restrict a generator's energy and operating reserves
bids, the generator would still receive a market-clearing price and additional
revenue to cover start-up and no-load costs.202 The capped bid could also set the market clearing price.
20. In
addition to the bid caps specified in the participating generator agreements,
local market power also will be limited through bilateral contracts between
load-serving entities and the generators.
Under the resource adequacy requirement, load-serving entities must have
enough resources to meet their demand to ensure the reliability of the
grid. It can be expected that some of
those resource requirements will need to be fulfilled with contracts with
generators within their load pocket to ensure that the resource is deliverable
during peak or congested periods.
Bilateral contracts are an effective way for a buyer to mitigate the
market power of a seller.203 The load-serving entities
can be expected to include provisions in these contracts specifying when a
generator must run to meet any reliability needs in that location and the price
to be paid. Whenever a generator is
scheduled to run under a bilateral contract, this will fulfill its must-offer
obligation in the participating generator agreement with the Independent
Transmission Provider.
1. Under the
participating generator agreements, when conditions are not competitive, that
is, when there are insufficient alternatives available to meet load in that
location, a generator must run to provide all its available capacity to the
grid, either by scheduling a bilateral transaction or bidding into the spot
market. The need for the generator to
be producing could be identified either in the day-ahead market based on
projected system conditions or in real time.
In the day-ahead market, all available capacity would include all
capacity not sold bilaterally and scheduled or on an outage. In the real-time market, all available
capacity would include all non-producing capacity (not delivered to the market)
i.e., capacity not on a planned or forced outage.204
1. The
Commission invites comment on how to structure the local market power
mitigation, particularly on how to define the noncompetitive conditions which
should trigger the mitigation, and on how bid caps should be structured for
generators operating under a participating generator agreement.
2. There are
some options for dealing with the risk of a forced outage inside a load
pocket. One is for a portion of
available day-ahead capacity to be exempt from the bid-in requirement to
reflect forced outage risk in real time.
Another possibility is to allow generators to provide all available
capacity in real time at a capped bid in lieu of bidding in the day-ahead
market to accommodate generators that have significant risk or opportunity
costs. A third option would vary
depending on whether the generator receives a reserve capacity payment. If the generator receives a capacity
payment, that payment compensates for the outage risk so the generator should
be obligated to deliver energy or to pay for substitute supply from some other
source. If the generator does not
receive a capacity payment, then it should not have to bear the risk for a
legitimate outage. Units declaring a
forced outage would be subject to audit by the market monitor. If the outage is found to be unjustified,
then the generator should be subject to a penalty. The Commission requests comment on the penalty that would be
appropriate to deter unjustified forced outages.
4. The Safety-Net Bid Cap
3. If bid-in
capacity is generally insufficient to meet both operating reserve requirements
and load, capacity rights associated with the resource adequacy requirement may
be exercised by load-serving entities that have secured sufficient capacity so
that they will not be interrupted.
However, in this situation, lack of demand response can result in
dramatic increases in market-clearing prices, even with comprehensive
mitigation on the supply-side, if imports can bid in at unrestrained
levels. In this case, imported power
from adjacent markets could set a market-clearing price above the marginal cost
of the highest cost unit dispatched within the market.205
Current markets in the Northeast and
Texas rely on a $1000 per megawatt-hour bid cap, regardless of market
conditions, as a safety-net that may be binding in this situation. The Commission proposes to adopt a
safety-net bid cap as part of the market power mitigation plan here. Under this proposal, no bid to supply can
exceed this level, regardless of cost or risk or location, even if the market
is confronted with a genuine operating reserve shortage. However, if the monitor establishes that
some units may provide power at a cost that exceeds the safety-net, a higher
price for those units would be justified.
In California, for example, imports are not allowed to set the market
clearing price. However, in the market
power mitigation framework proposed here imports would be allowed to set the market
clearing price in order to get a proxy for a scarcity price, up to a capped
value. If requirements cannot be
satisfied with bid-in imports that would be subject to the safety-net bid cap,
then load that has not met its resource adequacy requirement should be
penalized as described in the Resource Adequacy section. A safety-net bid cap, such as the $1000 per
megawatt-hour cap in the Northeast and Texas, can serve as a proxy scarcity
price under Standard Market Design. The
Commission requests comment whether the safety-net bid cap should be uniform
across an interconnection, so that there would be one cap applicable in the
East and another applicable in the West.
4. Comment is
requested on how to determine an appropriate value for such a cap. It is important to examine the implicit
trade-off between bilateral capacity payments, the safety-net bid cap and local
market power mitigation. That is, a bid
cap that constrains scarcity prices would be expected to translate into higher
bilateral capacity payments under a contract to fulfill the long-term resource
adequacy requirement. With a higher
safety-net bid cap, perhaps one based on the value of lost load, smaller
bilateral capacity payments would be required to maintain the same level
of resource adequacy in the absence of
price.
5. Mitigation Triggered by Market
Conditions
5. The
Commission proposes a fourth voluntary market power mitigation measure which
may be recommended by the market monitor during the Standard Market Design
implementation process, or any time thereafter. This measure, if needed, would apply to unanticipated and
sustained market conditions that would give the ability and the incentive to
exercise market power. For example,
extreme supply or demand conditions to which the market cannot quickly adapt,
such as the loss of significant hydropower capacity because of drought, or
force majeure events such as a major transmission line outage. These kinds of events, which are not
transitory, can provide opportunities to exercise market power even in a market
that is normally workably competitive.
It may be appropriate for other conditions to trigger this
mechanism. We seek comment on what
these triggers should be. Although
market- clearing prices would be expected to rise in these situations, and
perhaps sharply and significantly, it may be important for the market to have
the assurance that the price increases are attributable to the extreme
circumstances and not to the exercise of market power. An AMP mechanism such as those approved by
the Commission in New York ISO and California could provide this kind of
assurance.206
6. This kind of
mechanism may not be necessary in every region. If a market monitor proposes such a mechanism, the proposal must
include the specific triggers that would be used to initiate this form of
market power mitigation along with the details of the mitigation method. Since this form of market power mitigation
is for temporary market conditions, it will be equally important for the market
monitor to indicate the criteria to determine when the market has returned to
normal competitive conditions and this market power mitigation method will be
suspended.
7. The details
of this market power mitigation method, including the triggers, would be set
out in the Independent Transmission Provider's tariff. If market conditions developed that
satisfied the pre-determined triggers for the mechanism, it would be the market
monitor's responsibility to give notice to the public and the Commission that
the tariff mechanism had been triggered.
The mechanism would then automatically take effect until the conditions
developed that satisfied the pre-determined triggers for the suspension of this
market power mitigation mechanism. If a
market monitor proposes to use this form of market power mitigation, the
details of the mechanism and the triggers would be subject to comment by all
interested parties, and review by the Commission.
6. Establishing
Bid Caps or Competitive Reference Bids
8. The
mitigation for local market power, through the participating generator
agreements, relies on must-offer obligations to mitigate physical withholding
and bid caps to mitigate economic withholding.
Mitigating economic withholding entails determining appropriate bid caps
for all bid-in parameters.207 The unit-specific bid
caps in the participating generator agreements serve as proxy competitive bids
for energy, regulation service, and operating reserves, and for other
unit-specific operating parameters such as minimum run times and high and low
operating levels. Bid caps should
reflect the marginal cost – including opportunity cost – of offering all
capacity, including power that may be supplied only under limited conditions. Other bid-in parameters should reasonably
reflect operating conditions consistent with good engineering practice under
competition.
9. The
development of bid caps, especially for generators with significant opportunity
costs such as hydropower and energy-limited units, is difficult and can be
controversial. Nevertheless, this
mitigation plan would require that each generator, including hydropower and
energy-limited units, that may have local market power would need to have an
agreement establishing bid caps for all bid-in parameters if its power is
needed for the grid or local market power mitigation is necessary.
10. The
Commission has approved several options for setting default energy bids that in
some circumstances serve as energy bid caps.
They include: (1) default bids
based on various averages of previously selected in-merit bids; (2) default
bids based on various cost measures, usually a measure of operating cost
adjusted for fuel costs; and (3) default bids agreed through contract or
negotiation. For many fossil-fired units,
an estimate of operating costs plus a margin, such as ten percent, could
provide a reasonable bid cap for a unit's energy bid when competitive forces
cannot be relied on, similar to PJM's approach for mitigating reliability must
run units.208 Although fossil-fired
units may have opportunity costs not fully reflected by operating costs, an
adder, such as that used by PJM, is one way to allow flexibility to respond to
these uncertain costs. The Commission
requests comment on whether the level of the adder should be reviewed on a
region-by-region basis or if the Commission should establish a uniform adder,
and if so, at what level.
11. For
peaking units that are likely to set market clearing prices when they are
dispatched, the must-offer requirement coupled with mitigation that sets bid
caps at marginal cost could result in revenues that fail to recover fixed costs
over a reasonable period of time.
Although such units may recover additional revenue in capacity and
reserves markets, bid caps for these units could also reflect a
"scarcity" premium or adder to compensate for the lack of
price-responsive demand that would otherwise set the price when these units
were dispatched. The average cost of a
new peaking unit at a given location operated over a given number of hours
could form the basis for setting such a premium. This kind of adjustment to bid caps for peaking units could help
support reliability until demand-side measures for responding to price were
more fully incorporated in markets. The
Commission requests comments on whether this approach or other adjustments to
bid caps for peaking units might usefully substitute for demand response in the
near term.
12. For
hydropower and other energy-limited resources much of the difficulty in
determining an appropriate energy bid cap for these units comes from the
difficulty of assigning a value to their temporal opportunity costs. However, the times when it would be
necessary for the transmission provider to call on power from these sources are
likely to be times when prices are high and these units would want to be
scheduled in any event. At all other
times, hydropower units, in particular, should be offering all available
capacity as operating reserves since their marginal operating costs are close
to zero, but they may have high temporal opportunity costs. In other words, there appears to be no
economic reason why such units should not always be fully committed either to
the bilateral market or spot markets for operating reserves. Consequently, it appears unnecessary to cap
energy bids from such resources below the safety-net bid cap as long as their
bids to provide operating reserves were always in-merit. Alternatively, other energy-limited
resources might be allowed to submit a bid that states a total megawatt-hour
availability over the day and allow the market operator to schedule the power
from the unit in the hours when the price is highest. Comment is requested on these and other approaches to
establishing reasonable caps for energy bids.
13. Another
alternative for hydropower, and other energy-limited resources, would be for
the unit operator to submit a seasonal or monthly schedule for when the unit
would not be expected to operate. This
would enable, for example, hydropower units to specify the periods when they
would expect to need to preserve water or flow water to satisfy environmental
conditions. While these units have many
legitimate competing needs for the water flow, it is still possible for a
hydropower generator to engage in physical or economic withholding. In the existing ISOs, generators must submit
a schedule for planned outages, which is coordinated by the ISO to ensure that
outages occur when they are the least disruptive to the markets. The Independent Transmission Provider is expected
to continue to perform this outage coordination function under Standard Market
Design. Scheduling outages in advance,
coupled with auditing by the market monitor, would provide a way to evaluate
whether failures to run were from withholding or legitimate limitations. For hydropower units, for which the marginal
costs are primarily opportunity costs, this method may be a sufficient check
against withholding so that it might be unnecessary to have a bid cap for these
units. The Commission requests comment
on these alternatives.
14. Any parameters that
a generator may include in its bid may require a cap or other restraint. For example, PJM caps regulation service at
$100 per megawatt-hour, and New England uses energy prices to cap prices for
spinning reserves. Standard Market
Design would also allow availability bids for these products. The participating generator agreements
should also contain bid caps for these
operating reserves when they are needed for the operation of the
transmission system and non-competitive conditions exist. However, the Commission requests comment on
how to identify the options for determining competitive bid caps for regulation
service and operating reserves, including availability bids, that should be
established for day-ahead and real-time markets.
15. In
the New York and PJM day-ahead markets, the unit-specific energy bid cap
applies to the day-ahead market where separate bids for start-up and no-load
costs are also available and would also be available under Standard Market
Design. Market power mitigation should
also establish caps for these bids and
a variety of bid-in operating parameters, such as low and high operating
levels and minimum run times, if non-competitive circumstances would permit
sellers to manipulate these parameters to get unjustified higher up-lift
payments. PJM, for example, does not
mitigate the start-up and no-load bids or certain operating parameters, but it
only allows units to change these values once every six months. New York permits greater flexibility and
uses various screens to assess whether a seller is behaving non-competitively
and should be mitigated.
16. Several
approaches could be used for establishing bid caps for these particular
parameters. One possibility would be to
rely on engineering data, such as from the manufacturer about the specific type
of unit, to establish caps for start-up and no-load bids and certain operating
parameters, and give generators the flexibility to bid within those ranges
without mitigation. These ranges would
also be included in the generators' participating generator agreements. Just as with energy bids, a bid above the
range could be mitigated if the bid raised market-clearing prices
or uplift payments above a competitive benchmark level by a significant amount.
Because factors that might
cause generators to modify start-up and no-load bids and parameters such as
minimum run times generally are thought to be less variable than factors that
may influence energy bids, caps for these variables may be quite tight.209
In fact, PJM's approach to permit changes to these parameters once every
six months may be a simpler alternative that does not unduly restrict
competitive generator behavior. Comment
is requested on this approach and on other ways to prevent sellers from
manipulating these bids and operating parameters to increase market-clearing
prices and uplift payments.
17. In
the implementation filing, the market monitor would propose tariff language
that sets forth the process for setting the bid caps for individual units or
any formulas that might be used for this purpose. The market monitor would be responsible for collecting and
verifying data from these units to establish appropriate caps for energy bid
values consistent with the procedures in the Independent Transmission
Provider's tariff. This could be
controversial, especially for generators in load pockets that may effectively
face "mitigation" in most situations. The Commission requests comment whether the Commission should
establish a formula for determining the bid caps or whether the Commission
should review the proposals developed in each region.
7. Exemptions
18. It
is appropriate to exempt certain sellers from the market power mitigation. Specifically, sellers who control a small
amount of capacity in the market, for example no more than fifty megawatts,
would be exempt from mitigation.
Sellers with little capacity would have little incentive to exercise
market power since a non-competitive bid could eliminate their only unit from
the dispatch. However, the Commission
requests comment whether any other sellers should be exempt from the mitigation
because they have insufficient incentives to withhold.
8. Monitoring
19. Market
monitoring should be conducted on an on-going basis by a market monitoring unit
that is autonomous of the Independent Transmission Provider's management and
market participants. The market monitoring unit may be located within the
offices of the Independent Transmission Provider, to permit easy access to the
market data and operations personnel, or it may be physically located
elsewhere.
20. The
market monitor will be expected to report directly to the Commission, and the
independent governing board of the Independent Transmission Provider. This will include reporting at regular
intervals on the general performance of the markets in its region and
reporting, on a timely basis, observed attempts at market manipulation or
factors that impair the efficiency of the market. Although the market monitor will be accountable only to the
Commission and the governing board, it should share its analyses and reports
with the management of the Independent Transmission Provider and the Regional
State Advisory Committee. This will
enable the committee to carry out its advisory functions in an informed manner.
21. The market monitor must focus both on the
functioning of the markets run by the Independent Transmission Provider as well
as the conduct of individual market participants. The market monitor should focus on identifying factors that might
contribute to economic inefficiency.
Such factors include market design flaws, inefficient market rules,
entry barriers to new generation, including distributed generation, barriers to
demand-side resources, transmission constraints and market power. In monitoring for exercises of market power,
the market monitor should focus principally on detecting economic and physical
withholding (as distinct from the normal operation of supply, demand, and true
scarcity). For entities that own both
transmission and generation assets, withholding behavior could include both
generator and transmission outages. For
example, instead of directly withholding a generator's power, a market
participant with transmission assets could effect the same end by derating a
transmission line needed to deliver the generator's power to the market. Monitoring should be designed to detect this
kind of behavior.
22. The
Commission requests comment on whether the market monitor should also be
responsible for monitoring the Independent Transmission Provider's operations,
in addition to the markets and the market participants. Specifically, should the market monitor
evaluate whether the Independent Transmission Provider treats market
participants neutrally, without undue discrimination?
23. To
meet its responsibilities, the market monitor must have the ability to collect
and evaluate necessary data provided by the Independent Transmission Provider
and market participants. The market
monitor would have the responsibility to propose to the Commission, and the
Independent Transmission Provider's board changes to market rules, if they
provide inefficient incentives to market participants, and to promptly identify
circumstances that may require additional market power mitigation so that
remedies can be put in place prospectively.210
The market monitor would also be required to provide a comprehensive
analysis and report of market structure and individual generator conduct in the
spot markets, at least annually, to evaluate the overall efficiency of spot
market operations, the market for Congestion Revenue Rights, and how the
balance between resources and demand in the region affects the market's ability
to efficiently serve load at least cost.
In addition, the market monitor must also annually assess the
effectiveness of any mitigation actions taken and review the terms, conditions,
and bid caps in the participating generator agreements. Finally, the market monitor must engage in
surveillance to insure that market participants comply with the rules in the
Independent Transmission Provider's tariff.
24. The
work and findings of the market monitor must be integrated into the regional
planning process. The market monitor's
analysis of the markets will identify load pockets and can help provide
direction for needed investment in generation, including distributed
generation, demand response capability, and transmission infrastructure to
improve the competitive structure of the markets.
25. The
Commission proposes here the basic elements of a market monitoring plan to be
used by each market monitor. The
Commission staff will convene a conference in the Fall to discuss and further
develop the essential elements that should be required in a standard market
monitoring plan. After getting
additional public input at the conference, Staff may propose additional detail
for the market monitoring plan, which the Commission may adopt, after an
opportunity for public comment.
a.
Framework for analyzing market
structure and market conduct
26. The
Commission intends to require the use of a core set of questions and analytical
techniques to be used by each market monitor to assess market structure,
participant behavior, market design, and market power mitigation. This will facilitate inter-regional comparisons. Examining this core set of issues using
techniques reflecting "best practices" would be an essential part of
the monitor's responsibilities that allows inter-regional comparisons. However,
specifying these core requirements here should not prohibit or
discourage monitors from expanding their analyses where regional differences or
unanticipated events warrant it. In
fact, because markets and monitoring are in a formative stage, the Commission
would need to continue to facilitate communication between market monitors to
share insights and develop common approaches.
27. An
important focus of market monitoring will be structural market conditions since
the Commission's ultimate goal is to foster structurally competitive regional
bulk power markets. Academic analysts
and market monitors have examined the competitiveness of current spot markets
using various approaches and data. Some
have focused on developing a simulated competitive benchmark that can serve as
a reasonable measure of the market's overall efficiency.211
Others have examined whether specific generator bidding behavior has
been consistent with profit maximization under competitive conditions.212
28. Some monitors have estimated whether average
generator profitability would cover costs of a gas-fired peaking unit and
provide sufficient inducement for entry.213
Most monitors also track bidding patterns so that sudden, inexplicable
changes can be investigated promptly to evaluate whether market power is a
cause of the change.214 Monitors also track
changes in concentration, unplanned generator and transmission outages, and
changes in various operating parameters that may signify market power problems.215
Although the reports have been very useful in enhancing our
understanding of a wide range of issues, the approaches have been varied, key
questions have been framed differently and, importantly, the markets have not
had the same design. As a consequence,
results have not been comparable across markets. With the widely varying market designs of the past, greater
comparability across regions was not feasible.
However, these analyses have served as a useful starting point for
developing a standard analytical framework.
29. The
Commission proposes to require each monitor to perform a structural analysis of
the region that would include: (1)
market concentration including by type of generation, (2) conditions for entry
of new supply, (3) demand response, and (4) transmission constraints and load
pockets that give sellers the ability and incentive to exercise market
power. This analysis would be performed
prior to the implementation of the Standard Market Design, in order to
implement the market power mitigation.
It also would be performed annually to reassess and adjust the market
power mitigation, and to evaluate the conditions of the market.216
30. In
addition, the Commission proposes to require an annual assessment of the
performance of the markets operated by the Independent Transmission
Provider. This assessment would use a
competitive benchmark to assess market performance as an additional means of
assessing the effectiveness of the market power mitigation.
31. Comment
is requested on how the monitor should address these and other topics, to develop useful measures that permit
inter-regional comparisons. For
example, concentration measures stratified by generator type might better
identify competitive alternatives under various demand conditions. Estimates of generator profitability, such
as PJM and ISO-New England have used in the past, might be a useful measure of
incentives for generator entry. These
estimate the degree to which a hypothetical unit operating in all profitable
hours would have recovered its costs.
Although it is not a definitive profit estimate for any particular
generator, it may be a useful measure for comparing incentives for generator
entry across market or regions.
32. A
core set of questions and analytical techniques must also be developed for monitors to use to evaluate conduct of
market participants in the transmission and spot markets operated by the Independent
Transmission Provider. Analysis of
generation and transmission outages is central because these can be forms of
withholding. Because some owners of
generation also own transmission, monitors must review any planned transmission
outages, for example, to make sure that scheduling outages could not be used to
enhance or create opportunities to exercise generator market power. Analysis of generator conduct might also
include a review of bidding behavior in the spot markets operated by the
Independent Transmission Provider to identify any auction design flaws that may
give market participants an unanticipated incentive and ability to manipulate
market-clearing prices or up-lift payments.
The monitor should also evaluate the effectiveness of the participating
generator agreements in mitigating market power where market structure is not
sufficiently competitive.
33. Finally,
the monitor must analyze the operation of the congestion management system and
the market for the resale of Congestion Revenue Rights for evidence of market
power or manipulation. The monitor must
also assess whether those who collect congestion revenues are in a position to
influence transmission expansion plans that can affect congestion revenues and
report on the incentive structure of those arrangements.
34. Any
flaws in the market rules that may be identified by the monitor and any market
participant conduct that indicates the ability to exercise market power under
the market rules in effect would be remedied prospectively after Commission
authorization of changes to the market rules.
However, if the conduct violates existing rules, the market monitor must
have the necessary tools to investigate the conduct and to penalize it. These will be discussed in the sections
below.
35. An
important adjunct to the market power mitigation and monitoring plan will be a
clear set of rules governing market participant conduct with the penalties for
violations clearly spelled out. The
Commission proposes to require the Independent Transmission Provider to include
in its tariff certain minimum behavioral rules, which will be monitored by the
market monitor. These will include, at
a minimum, the following rules:
(1) Physical Withholding: Entities may
not physically withhold the output of an Electric Facility (Generating unit or
Transmission Facility) by (a) falsely
declaring that an Electric Facility has been forced out of service or otherwise
become unavailable, or (b) failing to comply with the must-offer conditions of
a participating generator agreement.
(2) Economic Withholding: Entities may
not economically withhold by submitting high bids that are not consistent with
the caps specified in the tariff or the participating generator agreements.
(3) Availability Reporting: Entities must
comply with all reporting requirements governing the availability and
maintenance of a Generating Unit or Transmission Facility, including proper
Outage scheduling requirements.
Entities must immediately notify the Independent Transmission Provider when
capacity changes or resource limitations occur that affect the availability of
the unit or facility or the ability to comply with dispatch instructions.
(4) Factual Accuracy: All
applications, schedules, reports, or other communications to the Independent
Transmission Provider or the Market Monitor must be submitted by a responsible
company official who is knowledgeable of the facts submitted. All information submitted must be true to
the best knowledge of the person submitting the information.
(5) Information Obligation: Entities
must comply with requests for information or data by the Market Monitor or the
Independent Transmission Provider that are consistent with the tariff.
(6) Cooperation: Entities must assist
and cooperate in investigations or audits conducted by the Market Monitor.
(7)
Physical Feasibility:
All bids or schedules that designate resources must be physically feasible
within the limits of the resource, i.e., the resource is physically capable of
supplying the energy, ancillary service, or demand response needed to fulfill a
schedule or bid according to the physical limitations of the resource.
36. These
rules must be accompanied by predetermined penalties, as discussed below in the
Enforcement section.
b.
Data Requirements and Data
Collection
37. Data
collection should be targeted to providing monitors with information necessary
to answer the required questions covering critical issues regarding market
structure, participant behavior, and market design. These data would be acquired from various public sources and in
the normal course of operating the markets.
They would include: (1) market statistics and indices, such as
market-clearing prices and system-wide congestion costs; (2) data on system
conditions, such as transfer capability and planned and forced outages; (3)
information on other prices, such as fuel prices and prices in adjacent
markets; (4) information on load served from the spot market; (5) data relating
to generator bidding patterns; and (6) information on Congestion Revenue
Rights.
38. In
addition, monitors must have the ability to obtain data on generator production
and opportunity costs and information on the operating status of transmission
and generation facilities that relate to claimed outages or deratings. Generator-specific data on all relevant
costs and operating parameters – e.g., start-up, no-load, environmental,
fuel, maintenance, ramp rates, low and high operating levels, and heat rates –
may also be relevant to establishing appropriate bid caps for participating
generator agreements. These data when
combined with information acquired in the normal course of business operations
and schedules for planned outages should give monitors the information they
need to fully analyze the competitiveness of the markets operated by the
Independent Transmission Provider.
39. As
a condition for participating in the spot markets, and using the transmission
grid, market participants must agree to provide the market monitor with any
information requested. Since the ability
of the market monitor to perform his or her monitoring role is dependent upon
the ability to acquire the necessary information, the monitor must have the
ability to require market participants to provide information. This is an important enforcement tool. The Independent Transmission Provider's
tariff should specify the penalties that would apply to market participants who
fail to comply with an information request from the market monitor. Market participant objections to market
monitor information requests will be resolved by the Commission on an expedited
basis because delays in providing information could result in continuing harm
to the market. In any such dispute the
Commission will give substantial deference to the market monitor's stated need
for the information.
40. All
information obtained by the monitor that is specific to a market participant
would be treated confidentially. Any
disputes concerning how the confidential information could be used would be
resolved by the Commission, before the data are released to the public. Since the Commission has oversight
responsibility for wholesale electric markets, any data collected by the market
monitor would be available to the Commission
and the confidentiality of the data would be protected by the Commission
under its regulations.
c.
Reporting Requirements
41. At
a minimum, the monitor would be required to submit an annual report to the
Commission and the Independent Transmission Provider's governing board, and
share that report with the Regional State Advisory Committee. The report would include: (1) a general description of the market
operations, supply and demand, and market prices; (2) an analysis of market
structure and participant behavior following guidelines described above; (3) an
evaluation of the effectiveness of mitigation measures taken; (4) an overall
assessment of market efficiency perhaps using a simulated competitive benchmark
as some have developed; (5) an evaluation of barriers to entry for generating,
demand-side, and transmission resources; and (6) any recommended changes to
market design or market power mitigation measures to improve market
performance. The report would also
include a discussion and analysis of any region-specific issues that the
monitor judges important to achieving a competitive outcome. This could also be particularly useful to
the planning process in determining where expanded transmission capacity might
reduce market power problems in load pockets.
The annual report would be made public, with appropriate protections to
maintain confidentiality, if necessary.
42. In
addition, the market monitor will be required to report to the Commission,
through the Office of Market Oversight and Investigation, any instances of
conduct by market participants that appear to be inconsistent with the
Independent Transmission Provider's tariff.
Early reporting of questionable conduct will permit coordination between
the market monitor and the Commission's investigative staff to determine the
best methods for developing the facts and addressing conduct that could be
harmful to the market.
43. The
Commission requests comment whether additional reporting requirements are
needed.
d. Enforcement of the Tariff Rules
44. The
market monitor must play an important role in the enforcement of the market
rules contained in the Independent Transmission Provider's tariff. In this role the market monitor will need to
coordinate closely with the Commission's investigative and enforcement staff. However, to ensure effective enforcement,
the market monitor must have adequate authority to investigate market
participant conduct and the Independent Transmission Provider must have a set
of predetermined penalties to apply to conduct that is in violation of the
rules of the Independent Transmission Provider's tariff.
45. As
a condition of participating in the markets operated by the Independent
Transmission Provider and using the transmission grid operated by the
Independent Transmission Provider, the Commission proposes to require market participants
and transmission customers to agree to predetermined penalties that would apply
to violations of the tariff rules.
Since the tariff rules are intended to ensure the fair and efficient
operation of the markets, the penalties should be designed to deter conduct
that is inconsistent with the fair and efficient operation of the markets. Specifically, the penalties should deter
conduct that results in an economic benefit derived from a violation of the
rules. The penalties should, at a
minimum, require payment of the economic benefit derived by the violator from
violating the rules. Where the
violation could result in conduct that could be harmful to the reliability of
the grid, it would be appropriate for the penalty to be significantly higher to
serve as a deterrent for the conduct.
The Independent Transmission Provider's tariff must specify the
conditions that would apply for each level of penalty.
It may be appropriate to build into the tariff standards for mitigating the penalty. Some standards that could be used are: the impact on the operation of the grid, the financial impact on the violator, and any good faith efforts to maintain compliance. The Commission requests comment on the conditions that would justify mitigation of the penalty.
195The Commission's natural gas pipeline cases have used a definition of market power that examines the company’s ability to raise prices significantly above a competitive level for a sustained period. Alternatives to Traditional Cost-of-Service Ratemaking for Natural Gas Pipelines, 74 FERC ¶ 61,076 at p. 61,230 (1996); and cases cited id at n. 52. See also, Alternatives to Traditional Cost-of-Service Ratemaking for Natural Gas Pipelines, 70 FERC ¶ 61,139 at p. 61,403 (1995) (concerning transportation and storage services). These factors recognize that it is difficult to identify market power with precision, both because it is difficult to precisely identify the competitive price (which should recover both fixed and variable costs over the long run) and because it can be difficult to isolate the impact of one entity on the competitive price. These factors also recognize that there is an implicit cost/benefit assessment to decisions to intervene in the exercise of market power. The cost of intervention in transient price increases could be greater than the public benefit gained by the intervention. Commission decisions about when to intervene in an exercise of market power are important, but need to be tailored to the circumstances of the product and the industry. In the electric industry, electricity prices can spike for one hour or a few hours in ways that are less likely for natural gas pipeline transportation and storage rates, and the consequences can be quite different. Since the definition of market power and the decision when to intervene in its exercise are analytically distinct issues, in this rulemaking the Commission incorporates the concept of when to intervene in an exercise of market power into the choice of triggers for the market power mitigation mechanisms, rather than in the definition of what constitutes market power.
196Market power can also be exercised by creating barriers to entry so other suppliers cannot reach the market or by causing other supplier's production costs to increase.
197This is also true for certain types of ancillary services (e.g., reactive power) where specific generators may have the ability to exercise market power because of their location.
198This would include a broader group of units than what are often referred to as reliability must run units.

202SMD Tariff section F.1.11. The generator's legitimate minimum run times would also be honored under the provisions of SMD Tariff section F.1.5.
203See Comment of the Staff of the Bureau of Economics and the Office of the General Counsel of the Federal Trade Commission, Docket No. RM01-12-000 (July 23, 2002).
204Under the Standard Market Design tariff, all units scheduled day ahead under a must-offer obligation, but not needed in real time would get paid their start-up and no-load costs.
205Generators outside the region would not have participating generator agreements with the Independent Transmission Provider, with provisions for addressing local market power, and neither would marketers.
206See California Independent System Operator Corp., 100 FERC ¶ 61,060 (2002). See New York Independent System Operator, Inc. et al., 99 FERC ¶ 61,246 (2002). Although AMP was in effect in all of New York, it was only triggered on four occasions, reflecting conditions in eastern New York.
207These same considerations would apply if the Commission adopted an AMP-like mechanism with bid caps or competitive reference bids.
208This method may not work for fossil-fired units that are only permitted to run a limited number of hours due to environmental restrictions. These energy-limited resources are discussed below.
209For example, energy prices could change frequently because of differences in the cost of fuels such as natural gas.
210The changes would only go into effect after Commission approval.

216The monitor should particularly pay attention to concentration in the regulation and operating reserves markets, and consider the amount of supply relative to demand, and propose specific market power mitigation measures for these markets if necessary.
