Judging market performance by the ability to
provide consumers with a choice of high quality products at stable,
reasonable prices, the restructured electricity market is failing
from coast-to-coast. This paper demonstrates that the problems arise
from systematic market conditions and flawed market structures, not
from accidents, impatience or partial deregulation. The findings,
summarized in Table ES-1, compel policymakers to rethink electricity
deregulation.
Inevitably, the extreme tightness of supply
will ease somewhat, but the electricity market will remain a
difficult and dangerous one for consumers. Inflexibility of supply
and demand are basic conditions that render the electricity market
volatile and vulnerable to abuse.
· Short-term supply responses are constrained because of the difficulty of storing electricity· Significant additions to supply still require substantial lead times.
· The coordination of an integrated, real-time network has broken down because competition reduces the incentive for market participants to cooperate and makes it difficult for system operators to manage the electricity grid.
· Provision of reserve margins is uncertain in a competitive market, since no one has an interest in building excess capacity, suggesting that these markets may remain tight.
Behaviors in the economic and political marketplace make it clear that powerful interests helped to create and are exploiting this vulnerable market structure.
· Recent mergers that have increased horizontal concentration of generation and vertical integration between generation and transmission make the industry less competitive.
· Utilities cut back on investment in generation and transmission, blaming an uncertain regulatory environment, and simultaneously refused to open their networks to competitors, inhibiting the construction of competitive capacity.
· Inadequate transmission capacity and self-interested manipulation of access to the transmission system limits the ability of power to flow.
· Utilities resisted allowing consumers to aggregate their demand effectively and undermined the ability of consumers to self-supply by blocking or slowing the deployment of distributed generation capacity.
Pricing behavior indicates the existence of market power.
· Bidding behavior indicates an insufficient number of electricity producers to prevent gaming that drives prices to extremely high levels.
· Contracting behavior in the face of a lack of information and rigid rules distort price signals.

REREGULATION OR RESPONSIBLE
DEREGULATION
It is important to stress that we do not have
to deregulate every market, or every segment of every market. Markets
are a means to an end, not an end in themselves. If basic conditions
or market structures are not right, lower prices, higher quality, and
genuine consumer choice will not result. With a vital commodity like
electricity, consumers can easily be hurt, rather than helped, by
imperfect markets.
Policymakers have an obligation to actively
consider whether the underlying conditions are conducive to consumer
abuse and to take measures to prevent it. In 1997 they could get away
with the belief that the market would take care of things; in 2001,
they cannot. Policy makers must ensure that basic supply and demand
conditions, market structures and trading institutions are adequate
to support competition before deregulation. Competition must exist
before, and policymakers must monitor market performance closely
after, deregulation.
States that have not restructured, should not,
not until it can be demonstrated that restructuring can serve the
consumer interest. States that have not yet moved too far through the
restructuring process - particularly where generation has not yet
been divested or control of the grid has not yet been transferred to
an ISO/RTO -- should slow or stop the process until they gain
confidence that a true market for generation will can be created and
the grid can be operated in an manner the promotes reliability and
supports market transactions.
States where Humpty Dumpty has been broken and
is not likely to be put back together again should undertake vigorous
efforts to protect residential consumers. These should include rules
to prevent price spikes, law enforcement against pricing abuse,
requirements to participate in effective market opening transmission
organizations, opt out aggregation for small consumers, and
aggressive pursuit of distributed generation.
OPENING THE HIGHWAYS OF
COMMERCE
The failure to recognize the important role of
the continuing monopoly in distribution and transmission resulted in
the under-regulation of the wires segments of the industry. Since
generation assets are sunk and load is immobile, the wires business
stands at the intersection of many of the industry problems as an
essential, bottleneck facility in short supply.
These are the highways of commerce over which
electricity flows and this highway system is not a market. One of its
primary inputs is right-of-way, which relies on governmental power of
condemnation. The biggest obstacle to the expansion of transmission
capacity is public concern about negative externalities - ugly wires
and local health effects - not inadequate incentives. There is
virtually no redundancy in the system today and never likely to be
head-to-head competition in the wires business.
Because the wires problem is not a market
problem, proposals to let the marketplace solve it are not likely to
succeed. Given the market power that the wire "owner" would possess
and the non-market barriers to expanding capacity, profit
maximization would only result in the abuse of market power and the
creation of scarcity rents.
· The right model for transmission is a public or private entity imbued with the public interest and dedicated to ensuring that this essential facility fulfils it public functions - ensuring reliability and supporting nondiscriminatory market transactions.
· It must be independent of all market participants and directly responsible and accountable to public authorities for achieving those goals.
· The transmission operator must oversee mandatory, comprehensive open access and standardize transactions over as large an area as possible to minimize transaction costs and capture economics of scale and integration.
· Transactions must be transparent, with the creation of an exchange in which all rates terms and conditions can be identified.
· Brokers must be subject to rules that are similar to those applied to financial transactions like stock sales and dealings.
DEMONOPOLIZATION BEFORE
DEREGULATION
The generation market must also be
deconcentrated before it is deregulated.
· Markets should not be deregulated until an affirmative finding of the absence of market power is made by responsible antitrust authorities.· FERC should reconsider market-based pricing for markets that have not been found to be effectively competitive or utilities that fail to join nondiscriminatory transmission organizations.
· Aggressive policies to discipline abuse of market power should be implemented.
· Ownership limits should be established and additional mergers should be denied until effective market structures are defined.
· Caps on wholesale prices that are uniform throughout the relevant interstate market - most likely intertie-wide -- should be set to protect consumers from wild price swings and to prevent energy suppliers from forum shopping and pursuing beggar they neighbor behaviors.
FREEING THE DEMAND SIDE
WITHOUT PUNISHING SMALL CONSUMERS
The supply-side of the market and the highways
of commerce should be the focal point of policy. If the only way to
make electricity deregulation work is to punish small consumers for
using electricity when they need it most, these customer classes will
rightly vote to go back to the old system. Nevertheless, there are
policies that can free the demand side, without punishing it.
· Aggregation of small consumers should be promoted to overcome obstacles to their participation in the market.· Distributed generation, which adds generation resources and saves on transmission resources, should be facilitated with streamlined interconnection and favorable regulatory treatment.
· More effective programs for short-term reductions in demand among commercial and industrial customers must be developed.
· Retail prices must be capped during the transition to a fully competitive market.
I. PERFORMANCE OF
RESTRUCTURED ELECTRICITY MARKETS CHAOS HERE, CHAOS THERE, CHAOS
EVERYWHERE
The meltdown of electricity markets in
California, the first state to take electricity restructuring to its
logical (or illogical) conclusion, has voices raised and angry
fingers pointing in every direction. The public is in an
uproar.(1)
The California Public Utility Commission (CPUC) criticized the
industry heavily, and challenged the structure of the Independent
System Operator (ISO).(2)
The ISO shot back and criticized the
rules laid down by the CPUC and the behaviors it required of
utilities.(3)
The response of the Federal Energy
Regulatory Commission (FERC)(4)
has been criticized by a number of stakeholders including the
Governor of California and the Secretary of
Energy.(5)
The severe problems that restructured
electricity markets experienced this summer come as no surprise to
consumer advocates.
· An assessment of the structure of restructuring just prior to the start of the nation's first experiment in California, raised strong doubts that residential consumers would benefit much from restructuring.(6)· An analysis of the price spikes of 1998 in California and the mid-west led to the conclusion that market structural conditions create volatility in the electric utility industry and make the abuse of market power highly likely.(7)
· A review of deteriorating quality of service in 1999 reinforced these concerns.(8)
Amid this din, it would be nice if policy makers could have a little peace and quiet to reflect before having to make their next move. Unfortunately, because many states had started down the path of restructuring and advocates of deregulation will keep the pressure on to plow ahead by making excuses for these problems,(9) policymakers are going to have to make some very tough decisions for very high stakes before the cacophony of conflicting messages abates.
Because the noise coming from California is so loud, consumers must speak loudly and clearly to be heard. Those who insist that California cannot happen here, there or anywhere else are simply wrong. None of the excuses stands up to the scrutiny of objective empirical analysis.(10)
Although California made some mistakes, versions of its problems have already occurred and are continuing to occur in many other markets, for systematic reasons that are similar across markets.
· As Figure 1 shows, price spikes are not unique to California. There have been price spikes, summer after summer, all over the country.
· As Figure 2 shows, tight supply conditions leading to shortages and brown outs are not unique to California. These market conditions exist all over the country. To the extent that these conditions contribute to the problems, they are widespread.
· As Table 1 shows, theses are not accidents or aberrations. The underlying problems are structural and long term.

The stakes are staggering. Hundreds of millions
of dollars changed hands in a matter of days in the mid-west and West
Coast spikes of 1998 and 1999.(11)
Billions changed hands in a few months
in California in 2000. Consumers in San Diego have suffered increased
electricity bills in 2000 of $700
million(12)
and California utilities would appear to be in the hole for many
billion more,(13)
which they are seeking to recover from ratepayers. Thus, even short
periods of volatility demand vigorous policy responses.
This paper presents an explanation of the
causes of this market failure that emphasizes the systematic and
structural factors that have rendered the electricity market
vulnerable to abuse and prone to volatility. It relies primarily on
the results of investigations into the market chaos by regulatory
agencies and oversight authorities.
· Accidents - acts of God, or nature - do not only happen in California, they happen everywhere. The extreme volatility of these markets cannot be explained by a combination of weather and accidents.· The underlying tight market conditions are themselves the result of systematic problems that have not been solved. There are also ways in which new market institutions and transactions make the likelihood of accidents and their impact greater. Accidents do not just happen; controllable conditions and circumstances can make them more or less likely to occur and make their consequences more or less severe.
· Economic and political actions by utilities have created a highly concentrated, supply constrained market. Behaviors in the economic and political marketplace make it clear that there are economic interests that helped to create and exploit this vulnerable market structure.(14)
The key to solving the problems of the restructured electricity market is to recognize that the market failure is systemic and will not simply correct itself. Because problems are so severe, they inevitably will abate to some extent, but that does not mean that the market will function well. Refusal to address the systematic problems will prolong and frustrate any transition to an orderly market.(15) In fact, the failure to have a legitimate debate about which parts of the electricity market should have been deregulated in the first place has contributed to the fundamental problem because policymakers assumed the market would do things it could not.(16)
When a coherent, theoretically based view of the electricity market is taken,(17) as opposed to the ad hoc excuses offered by market participants, many of whom are profiting handsomely from the wild gyrations in the market, the need for fundamental policy changes becomes apparent. In the first round of electricity restructuring, policymakers seriously overestimated the ability of market forces to function in the electricity industry and underestimated the ability of large entities to take advantages of market weaknesses and flaws. This paper offers a comprehensive set of policy recommendations that outlines a much more active role for regulators in a number of aspects of the market.
II. THE EXPLANATION:
STRUCTURAL FLAWS IN ELECTRIC UTILITY MARKETS
A. CHALLENGES ON THE
SUPPLY-SIDE
There are systemic causes of the current
tightness on the supply-side of the market. Although the current
extreme tightness of supply may ease somewhat, inflexibility of
supply renders the market volatile and vulnerable to abuse.
· The elasticity of supply is low. Short-term supply responses are constrained by the difficulty of storing electricity.· Significant additions to supply require substantial lead times, making the supply-side "lumpy" and slow.
· Adequate reserve margins are uncertain in a competitive market because the provision of reserves is unattractive to business interests, unless peak prices are extremely high. Consequently, markets may be chronically tight or subject to extreme price volatility.
· Incumbents utilities have not only failed to add generation and transmission capacity, claiming uncertainty, but they also refused to open their transmission systems to competitors, which has reduced the willingness of competitors to build power plants.
· Highly concentrated local markets enable large generators to drive up prices by withholding supplies. In these tight markets, collusion is not necessary to drive prices up, parallel actions by a small number of generators is sufficient. Even though peaks are short in duration, they impose huge price distortions.
1. BASIC CONDITIONS
Supply is inelastic. Capital stock is long
lived and significantly determines supply and demand responses. While
the lead times for smaller, peaking generation units is not long,
larger baseload facilities still have substantial lead times, and
transmission facilities are especially difficult to bring on line. As
a result there are significant constraints in some areas on the
ability to expand supply.
Electricity is difficult to store. Battery
technology does not allow efficient storage for any but minimal uses.
The only effective way to store electricity is to pump water up hill
and keep it there until it is needed, but such opportunities are
limited. The only effective supply response to peak demand is idle
capacity, or reserve margins. On the supply-side, who has an economic
interest in building reserve margins to lower prices?
The physical behavior of electricity and its
demanding real-time characteristics are unique and create special
problems. Market participants can lean on the network or push power
into it without enforceable transactions taking place. After the fact
administrative accounting does not address the immense impact that
this behavior can have on a real-time basis.
Supply-side accidents (outages) are endemic.
Accidents affected a variety of technologies in a number of markets
at different times. Over the past three years, several major
categories of baseload plant - nuclear, fossil, and hydro - have
contributed to one or another of the unplanned outages. The problems
of technologies prone to outages are compounded by the inability to
store electricity.
2. STRUCURE
Analysis of the market structure leads to the
conclusion that market power can be exercised in these markets
because they are thin.(18)
They have also become
concentrated.(19)
The Federal Energy Regulatory Commission has been flooded with
requests for mergers in anticipation of the development of a
competitive market. For example, over 80 percent of the generation
capacity divested by utilities subject to restructuring has been
bought by subsidiaries of other utilities. In 1992, the year the
Energy Policy Act was passed, the largest 10 utilities owned
one-third of the national generating capacity, while the top 20 owned
60 percent. By 2000, the top ten had grown to control half of all
capacity, the top twenty to three quarters.
The national trend toward greater concentration
understates the problem because electricity product and geographic
markets are much smaller than the national market and much more
concentrated than the national market.(20)
With little supply available at
certain times and few competitors, there is no need to identify or
assume collusion, since supply is so
restricted.(21)
3. CONDUCT
The analysis of bidding behavior indicates that
market power has been exercised(22)
and there is no structural reason this
will change.(23)
A supplier with market power watches
the price rise, well above its level of costs, but does not sell
because he is confident that there are not enough other producers who
can enter the market.(24)
The problem of manipulation of bidding
is not one that is likely to just go away; nor is it limited to
conditions where markets are extremely
tight.(25)
Other conduct reinforces this
conclusion.(26)
Daisy chains passed power through a long line of sequential owners
without ever physically being delivered, except by the last
owner.(27)
This adds no new supply to the market. At least some of the
transactions on which the market was built were fabrications - deals
in which the buyer and seller were one and the same. The intention
was to signal a higher price. This institutional structure was
clearly implicated in several price run-ups when financial
transactions increased apparent demand. In tight markets traders with
financial problems add to the bidding for
power.(28)
Entities with needs for physical power compete with entities with
financial needs for power, but the underlying physical supply and
demand have not changed.(29)
Defaults on contracts in 1998 fueled the
frantic bidding partly because of the nature of trading. As prices
mounted, so too did the cost of failing to meet financially firms
contracts.(30)
It appears that a variety of other
institutions invoked contract clauses that sent some utilities
scrambling for replacement power.(31)
Moreover, given the chaotic and emergency situation under which
transactions were being conducted, and because rules had not been
clearly defined by authorities, even when they bought power,
utilities could not be sure what price they would be
charged.(32)
B. CHALLENGES ON THE
DEMAND-SIDE
Inflexibility of demand and its sensitivity to
weather renders the market volatile and vulnerable to abuse.
1. BASIC CONDITIONS
On the demand-side, we find that short-run
elasticity of demand is low because of the stock of capital equipment
deployed. Consumption is significantly influenced by weather. In the
long run, economic growth is a primary driver of demand, which is
generally not a public policy that can or will be used as a tool to
solve energy problems. The analysis of outages repeatedly points to
the problem of inelastic demand. Both the inability to conserve and
the lack of incentives to do so have been noted.
2. STRUCTURE
Restructuring has not allowed small customers
to express their demand effectively.(33)
Small consumers have not been allowed
to express demand effectively. In many instances, they were the last
allowed to shop. They were also prevented from forming buyers
cooperatives or aggregating demand in other ways. High transaction
costs and load patterns that exhibit relatively high peaks makes them
unattractive to many suppliers.
Self-supply has not been allowed or facilitated
by existing institutional structures.(34)
Distributed generation which would
allow small customers, especially commercial customers, to reduce
their demand and even add supply to the grid, have been blocked by
institutional arrangements.
3. CONDUCT
Virtually all demand, certainly for residential
customers, is still met by a utility obligation to serve. The
obligation to serve becomes a virtual edict to avoid blackouts at all
costs.(35)
Consumers have generally supported
this continuation of the fundamental principle of utility service.
Electricity service is just too important to be unreliable.
However, in an unfettered market for supply
there are adverse consequences of this behavior. It is difficult for
utilities to exercise restraint as supplies become
tight.(36)
Utilities need physical supply to meet
their load. Marketers can default and negotiate or litigate damages
later, but when the lights go out, utilities have experienced a
critical, real time problem with severe
consequences.(37)
This difference places them at a
disadvantage in market transaction
relationships.(38)
For all the focus on market efficiency in restructuring, the ultimate
test of electricity service is keeping the lights on, and some
entities still have the obligation to ensure that they do. The
obligations and incentives of these entities drives them to what can
be considered extreme behavior from a simple market point of view.
They are driven to pay an awful lot to meet
demand.(39)
Pricing structures also give little incentive
to alter demand in the short-term. These pricing and marketing
structures can be changed, but they are long-standing and may
encounter consumer resistance for a variety of reasons. One of the
key factors that drove prices up was the need of utilities to ensure
physical availability of supplies.
Suppliers have blamed small consumers for price
spikes-for failing to "respond" to price signals at the time of peak
demand. Energy conservation should be encouraged, but the fact
remains that small consumers have very limited ability to
significantly reduce demand, particularly at certain peak times. Heat
waves to which high price apologists point to justify prices
increases result in serious illness and deaths when consumers, in
particular the elderly and ill, are forced to cut back air
conditioning use in order to reduce electric bills.
Restructuring may require much more attention
to interruptible rates for large customers, not small residential
customers, to facilitate the response to tight markets. Interruptible
customers must be prepared to actually be
interrupted.(40)
New incentives in a restructured
market call into question whether utilities will live up to the
non-price terms of their interruptible tariffs, given the high price
they can fetch for released power or avoided for purchased power.
C. THE HIGHWAYS OF
COMMERCE
The wires components of the industry -
transmission and distribution, which are the highways of commerce
over which electricity flows - are presently natural monopolies and
are likely to remain so for the foreseeable future. Since generation
assets are sunk and load is immobile, the transmission system stands
at the intersection of many of the industry problems.
· The breakdown of coordination of an
integrated, real-time network in the restructuring industry occurs
because competition reduces the incentive for market participants to
cooperate and makes it difficult for system operators to manage the
electricity network.
· Inadequate transmission capacity and
restrictions on access to transmission limit the ability of power to
flow.
· Manipulation of access to the
transmission system for self-interested profit motives makes problems
worse and frustrates the ability to expand supply.
· As a constrained bottleneck facility
that restricts expanding supply, the transmission system facilitates
this manipulation.
1. BASIC CONDITIONS
One of the central activities of electric
utility monopolies is to balance load -- to aggregate customers who
use electricity at different times of the day or year. By bringing
together customers with dissimilar load patterns, utilities are able
to use their facilities more fully -- to balance periods when some
customers are off line while other customers who are on line.
Empirical studies show strong economies are achieved by coordinating
supply and demand.(41)
Ironically, in a restructured environment
utilities discover that their systems do not perform as
rated.(42)
This is a systemic factor that must be
brought into the planning process. The DOE Market Power report
affirms the importance of transmission capacity and pricing as a key
condition for the exercise of market
power.(43)
Creation of markets for electricity services
requires a huge growth in transactions. These transactions create
heavy administrative requirements in an industry that exhibits
economies of coordination. Directly related to the transactions and
managerial functions are facilities costs. Demands on network
facilities are likely to increase as a result of the wide range of
new transactions taking place. The physical facilities to support
these transactions will have to be constructed and maintained. An
increase in the number of transactions may require costly
improvements to the transmission system in order to ensure
reliability.(44)
Prior to the price spikes of 1998, the number of traders increased
over 50 fold; the quantity traded increased several hundred
times.(45)
2. STRUCTURE
The recent DOE outages report underscores
technology constraints as a systemic problem. The transmission
resource is clearly limited.(46)
Similar constraints on the
availability of distribution have been
noted.(47)
Transmission is difficult to repair or replace in response to
outages.(48)
This then places a premium on flexibility of supply and reserve
margins, but neither of these is well accommodated in the
industry.(49)
The transmission supply problem is pervasive
and widespread.(50)
This is reflected in both the inability to move power between regions
and the existence of load pockets within regions. In the near term
there is little that can be done about these constraints. This
condition has existed for some time.(51)
However, it is clear that the
introduction of competition has put a strain on an already stressed
asset.(52)
Vertical integration between generation,
transmission and distribution makes entry more difficult and creates
an ongoing problem about codes of conduct to govern the treatment of
non-affiliated entities.(53)
Moreover, the rules for allocating the
scarce transmission resource during times of stress were far from
optimum.(54)
In a competitive market, some entities gain an interest in hoarding
this asset.(55)
As a result, markets may have appeared more constrained to buyers
than they were in actual physical terms.(56)
Conduct of the transmission organizations will
be dictated by the form of governance. An intense debate has raged
over the rules of participation and decision-making, but the CPUC's
displeasure with the California ISO underscores how rigorous the
governance of the transmission organization must
be.(57)
The ISO is a nonprofit organization
with a self perpetuating board made up of stakeholder
representatives. The CPUC argues that industry representation on the
board has resulted in rules that make abuse of market power feasible,
if not likely. The board is responsible to neither stockholders nor
government entities. FERC oversight is virtually non-existent.
The CPUC is particularly concerned about the
refusal of the ISO to provide the data necessary to investigate
abusive bidding practices. The market monitoring function may prove
to be extremely important. Monitoring and disclosure of resource bid
prices, operating characteristics and demand bid prices under
multi-settlement may be necessary to provide better information to
market participants and transparency of transactions.
3. CONDUCT
With a mix of planned and market driven
behaviors interacting with genuine concerns about physical shortages,
the actual state of the available physical system is difficult to
perceive.(58)
Our analysis of the price spikes concludes that this uncertainty has
been exploited to raise prices.
To the extent that withholding supplies is a
strategy, it is dependent upon the inability of competitors to offer
supplies. Thus, the exercise of market power can be enhanced if
competitors can be prevented from entering the
market.(59)
The mechanism for doing this is to
prevent the transmission of power or to raise the price of
transmission services.(60)
In the former case, the generation
owner captures the rents. In the latter case the transmission owner
captures excess profits.(61)
Large entities tend to gain regionally
dominant positions, especially where they control transmission.
Because geographic markets are small, market power can be easily
exercised in specific markets.(62)
Because many of the entities are
vertically integrated, there is no dispute over these rents and they
are not competed away.
Although the outage report did not seek to
discover manipulative behavior as part of its study, certain findings
may indicate problems in this regard. The business
factors(63)
and the failure to preserve
records(64)
are consistent with our finding in the
analysis of price spikes. The DOE Market Power report concluded that
the empirical evidence clearly indicated market power had been
exercised in some restructured markets(65)
and the potential for its exercise in other markets is
substantial.(66)
One of the most important changes in behavior
that affected the market during the price spikes and outages is to
reduce the ability of system managers to coordinate and run the
transmission system. The problem stems both from complexity and from
a lack of cooperation. Market participants do not have an incentive
to cooperate.(67)
There were also complications of financial and
ownership relationships between
entities.(68)
Who owns what and who has the obligations to provide the various
services that support the movement of electricity were not always
crystal clear.
The outage report raises the problem of
transaction pressures in a number of ways. An unwillingness to share
best practices is a generic problem.(69)
Inadequate notice of
problems(70)
and business
factors(71)
also fall into this category. Even more fundamental is the lack of
authority of the ISO to respond to
problems(72)
and an absence of
rules.(73)
Thus we have a new market with a multitude of
complex transactions. One of the most important requirements for
coping with this new market situation would be good information.
Unfortunately, such information is not generally available during
difficult periods. There is simply no centralized, reliable source of
information.(74)
Information is much more difficult to gather for system operators.
Moreover, the brokers who were the sources of information may well
have interests that would be served by skewing information in one
direction or another.(75)
A number of information and management weaknesses are noted including
inadequate forecasting tools,(76)
a lack of monitoring instruments,(77)
and little real time information to respond to
problems.(78)
Although not strictly a problem of
"manipulation," the outage report identifies incentive and behavioral
problems that can be classified in this category. The complaint about
inefficient short-term transactions is essentially a complaint about
the market transaction mechanism.(79)
The new market also elicited a reliance on nonfirm sales, which
simply could not be sustained in a stressed
market.(80)
IV. POLICY
RECOMMENDATIONS
A. REREGULATION OR
RESPONSIBLE DEREGULATION
Before we begin offering recommendations about
how to make the electricity market work better, it is important to
stress that we do not have to deregulate every market, or every
segment of every market. Markets are a means to an end, not an end in
themselves. If basic conditions or market structures are not right,
lower prices, higher quality, and genuine consumer choice will not
result. With a commodity as vital as electricity, consumers can
easily be hurt, rather than helped, by imperfect markets and policy
makers should err on the side of caution.
The market looks orderly when capacity is
plentiful or transmission is less strained. At those times, the
chance that accidents will trigger painful events and the opportunity
to abuse market power will be reduced. Policymakers might have hoped
that such conditions would smooth the transition to a competitive
market, but that has not been the case, since it is now clear that
untoward events occur repeatedly and market participants have the
incentive and ability to exploits those events. In 1997 policymakers
could get away with the belief that the market would take care of
things; in 2001, they cannot. Policymakers have an obligation to
actively consider whether the underlying conditions are conducive to
consumer abuse and to take measures to prevent it. Given the observed
behavior of markets, policymaker should be prepared to act in four
areas.
· Policy makers have an obligation to ensure that the basic conditions are adequate to support competition before they deregulate. It is simply irresponsible to create markets that suffer from significant problems like inadequate capacity at the outset.· Market structures must support competition. The number of suppliers and their ability to bring product to market must be sufficient to deliver workably competitive markets. Highly concentrated markets with bottleneck facilities that lack open access rules make the market vulnerable to the exercise of market power.
· Market institutions should be developed before, not after, trading begins so that conduct is transparent and disciplined by market forces. Undeveloped information and trading mechanisms are prone to manipulation. When abuse occurs under such circumstances, it is no accident; it is the result of bad public policy choices or poor policy implementation.
· Competition must exist before markets are deregulated and policymakers must monitor market performance. Aggressive policies to discipline abuse of market power should be implemented. Any entity that engages in actions that tend to tighten electricity markets and then seeks to exploit that situation through sales at inflated prices should be presumed to have engaged in market manipulation. They should bear the burden of proving that they are not guilty of profiteering and the penalty for market manipulation should be severe.
States that have not restructured, should not,
not until it can be demonstrated that restructuring can serve the
consumer interest. States that have not yet moved too far through the
restructuring process - particularly where generation has not yet
been divested or control of the grid has not yet been transferred to
an ISO/RTO -- should slow or stop the process until they gain
confidence that a true market for generation can be created and the
grid can be operated in a manner the promotes reliability and
supports market transactions.
States where Humpty Dumpty has been broken and
is not likely to be put back together again should undertake vigorous
efforts to protect residential consumers. These should include rules
to prevent price spikes, law enforcement against pricing abuse,
requirements to participate in effective market opening transmission
organizations, opt out aggregation for small consumers, and
aggressive pursuit of distributed generation.
While the states pause or backtrack in their
restructuring efforts, federal policymaker must confront the failure
of the interstate market. If federal authorities cannot create an
effective interstate market, states will inevitably fail in their
restructuring efforts. Unless comprehensive federal reforms are
enacted, the chances of success at the state level are slim.
Regardless of where they are in the process, all states should review
consumer protection mechanisms and policies that restrict the ability
of small customers to express their demand.
Policy action should be based upon specific
findings of conditions that render a specific market vulnerable to
abuse. The goal is an orderly, efficient market; the means should fit
the end. While a specific set of regulatory interventions will not
fit every market, regulatory do-nothing policy does not fit every
market either. If policymakers cannot confidently conclude that these
conditions will be in place, they should not deregulate or
restructure the industry.
B. THE IMPORTANCE OF
TRANSMISSION SYSTEMS
The transmission system lies at the
intersection of two powerful and difficult functions in the
restructuring industry. It must balance the physical demands of
reliable power with the economic demands of efficient markets. It is
simply impossible to conceive of reliability issues that do not have
market function impacts and market function issues that do not have
reliability impacts.
There are certain functions that the system
operator must perform if it is to provide reliable electricity and
support efficient market operations. As has been argued throughout
this paper, the structures that are put into place will determine how
the industry participants behave in performing those functions. Of
course, market participants perform these functions by taking action
in the marketplace. The way they conduct themselves generally
reflects the institutions which they represent and the (internal and
external) rules that the institutions must obey. The institutional
structure affects the conduct of business that performs the functions
of the electricity system.
The rules of the operation of the grid must be
in place to ensure both efficiency through competition and
reliability of the grid. To the extent that coordination can lower
costs, through lowering reserve requirements, this function too
should be preserved. However, the rules must be competitively
neutral.
The network operator must monitor and run the
network in a manner that executes transactions and clears the market
physically and financially. Even if there were no sunk costs,
proprietary interests in facilities, or diverse organizational
entities involved (investor owned, consumer owned, publicly owned)
implementing an industry structure to accomplish the goals of
reliability and market operations would be difficult enough. With the
existing facilities, interests and institutions in place, it is
extremely difficult, if not impossible.
The ultimate goals of the formation of
transmission organizations are to ensure reliable operation of the
electricity grid and efficient market transactions for electricity
services through effective management of transmission functions.
Where market transactions can be relied upon to accomplish this goal,
they should be, but when they cannot, regulated transaction must be
used. Most people prefer to do business in stable markets.
1. HIGHWAYS OF COMMERCE
Policymakers cannot force entities to compete
in the marketplace, they can only provide the opportunity and hope
incentives will elicit entrants. In the electric utility industry,
the transmission system is the highway of commerce. Access to and use
of the grid determines whether the opportunity exists. The
effectiveness of competitive markets will be substantially affected
by the ability to move electricity between states. To date, federal
policymakers have done a terrible job of ensuring that the
transmission system is available and adequate to support the
interstate market in electricity.
Commerce is the key to competitive efficiency.
Without open highways of commerce the goals of restructuring simply
cannot be accomplished from both the market abuse and market
efficiency points of view.
· Because the ability (or willingness) of entities in the market to expand supply is limited, entry from outside the market must be encouraged - particularly new players from other geographic areas. Therefore, an effective interstate market would make the exercise of market power much more difficult.· An effective interstate market would make efficient generation of electricity much easier since most states are too small to constitute an efficient market in electricity. Even New York and California appear to be too small, at least in the near to mid-term.
· An effective interstate market would also enhance the quality of supply. Economies of coordination are still strong in the physical marketplace.
The electricity market is a complex, highly
differentiated economic market composed of numerous interrelated
products and geographic areas. There are a variety of different
products in different markets including real time physical markets
for energy, reserves (ancillary, backup), and capacity. These are
overlaid with procurement markets for services and financial markets,
where commitments are exchanged including markets for energy futures
of varying lengths and transmission services of varying lengths and
firmness.
The size of markets will be wholly determined
by administrative decisions, since the flow of electricity must be
managed on an active basis.(81)
It must be big enough to be reliable and efficient. Existing ISOs are
too small to ensure reliability or efficient markets.
Public policy must open the wires and ensure
that physical and financial transactions can be executed quickly and
effectively.
· Mandatory, comprehensive open access is necessary.· The transmission operator must standardize transactions over the largest areas possible to minimize transaction costs and maximize the potential efficiencies of scope and coordination.
· Transactions must be transparent, with the creation of an exchange in which all rates terms and conditions can be identified.
· Brokers must be subject to rules that are similar to those applied to financial transactions like stock sales and dealings.
The goal of a transmission organization should
be to promote a broad market that allows all resources to compete in
all markets. All resources should have access to all markets through
timely interconnection. All means to meet capacity needs must have
equal access. The current institutional structure emphasizes
generation at the expense of transmission, demand-side management
(especially weak at present) and distributed energy (largely
precluded or reduced by current institutional obstacles).
The guiding principle of market design is to
achieve market prices that are certain and can be relied upon.
Pricing mechanisms should be transparent - known in advance and not
subject to arbitrary change. Therefore the pricing mechanisms should
avoid after the fact administration, discontinuity between regions,
volatility and excessive reliance on locational tariffs that make
hedging difficult. Uniformity throughout the market (including rates,
terms and conditions) minimizes artificial geographic barriers that
may impede market development. Prices should be based on cost
causation principles, or determined by market-based solutions, only
where markets are workably competitive, so that resources are used
efficiently.
Operational rules must be compatible throughout
the market, and executed on an efficient (one-stop) basis to
facilitate long term transactions (such as interconnection) and allow
short term decisions (such as scheduling capacity, congestion
management) to be executed with certainty. Thus, the operation and
pricing mechanisms should endeavor to ensure that transmission
services can be procured on a predictable basis, distinguish
effectively between energy and transmission, allow for firm
curtailments, firm physical delivery and transportability of services
across regions and promote market liquidity by designing rules to
induce supply in thin markets including firm transmission rights and
regulation services.
Trading institutions must also be more highly
developed quickly. The overheating of the market in 1998 reflects a
fundamental lack of institutions to convey information and ensure the
soundness of transactions. The situation has not improved greatly.
Measures to ensure openness and confidence in transactions should be
taken. Securities and commodity exchanges impose rules to protect the
public and ensure an orderly market. Power exchanges should too.
Power exchanges should follow the pattern of
stock or mercantile exchanges. These impose rules on traders that
seek to ensure transparent pricing, control the flow of trading,
impose memberships criteria, require registration of participants,
and manage the types of trades including issues such as short
selling, margin requirements, credit requirements and option rules.
There is no reason that a physically important and difficult to
manage commodity like electricity should not be subject to rules at
least as stringent as those we impose on mere financial
transactions.
2. RELIABILITY
Unfortunately, from the perspective of simple
economic efficiency, the transmission system is also the key to the
reliability of the electric utility industry. The electricity grid is
an extremely demanding, real-time physical system. Reliability of
this system is a true externality. Few individual consumers or
utilities can create their own reliability (not without incurring
very substantial costs). Every individual's reliability is dependent
on the behavior of neighbors. Reliability is a regional, if not
national, problem that requires a regional, if not national,
solution.
The transmission functions are, broadly
speaking, the operation and monitoring of the network in the near
term and the planning and building of the network in the long term.
Short-term reliability, essentially congestion management, receives
the greatest amount of attention. Issues such as outage scheduling
for transmission and generation, control of path flows to prevent
problems and redispatch or curtailment schedules to respond to
problems must be handled in a competitively neutral manner. However,
long term capacity planning and expansion must also be addressed. The
process is laborious and promises to keep transmission capacity in
short supply. Incentives for congestion relief and interregional
expansion are important, but there are additional obstacles including
citing, coordination and environmental concerns that are independent
of marketplace incentives.
Given the above analysis, it would only be a
slight exaggeration to conclude that the failure to develop effective
transmission organizations in the interstate market is the single
greatest cause of the failure of electricity restructuring. The
structural problems in the electric utility industry are so severe,
the role of non-discriminatory access to the transmission system so
fundamental to an effectively competitive interstate electricity
market, and the resistance of vertically integrated incumbent network
owners so vigorous, that the FERC's proposed voluntary negotiations
will fail to solve the problem in a timely manner. There is simply
not enough muscle in the Final Rule to induce the incumbent utilities
to part with their market power voluntarily. Nor do we believe that
they should (or could) be bribed to do so. They must feel compelled
to do so. At the federal level, creating effective transmission
organizations would be the single most important step to alleviate
many of its problems.
The failure to recognize the important role of
the continuing monopoly in distribution and transmission resulted in
the under-regulation of these industry segments. If the object of
public policy is to allow competition in the wholesale supply of
generation to find demand in a competitive retail sector, the
monopoly wires between the two must be operated in a rigorously
effective manner to support competition.
As currently configured, the transmission and
distribution wires come nowhere near being operated in an open
access, procompetitive manner. The Federal Energy Regulatory
Commission's (FERC) authority has been repeatedly challenged, which
has led it to take a voluntary approach to open access. The
uncertainty has also created timidity in design of its open access
regimes. As a result, the transmission grid will not support
competition as firmly as it should.
3. GOVERNANCE
The governance of the new transmission
organizations is critical. The transmission network is an essential,
bottleneck facility in short supply. At present and for the
foreseeable future, it is a natural monopoly. One of its primary
inputs is right-of-way. This input exists to a substantial degree
through the exercise of governmental power - condemnation. One of the
biggest obstacles to the expansion of transmission capacity is public
concern about negative externalities - ugly wires and local health
effects. Consequently, zoning and citing are critical and difficult
issues.
Proposals to let the marketplace solve the
transmission problem are just another expression of the same
theological devotion to deregulation at any price that got us into
this mess in the first place. The problem with transmission is not a
market problem and the solution is not to declare a market. The right
model for transmission is a public interest model that creates an
entity, public or private, dedicated to ensuring that this essential
facility fulfils it public functions - ensuring reliability and
supporting nondiscriminatory market transactions. The entity must be
responsible and accountable for achieving these, and only these
goals.
Creating such an entity does not mean it cannot
be efficient or involve incentives to ensure that those goals are
accomplished in a speedy and effective manner. It does mean that the
goal is not simply to make a profit, or to maximize profits. Given
the market power that the transmission "owner" would inevitably
possess and the non-market nature of the barriers to expanding
capacity, the entity cannot be a profit maximizing entity. If it
were, it would abuse its market power and create scarcity rents.
Increasing the profitability of the transmission entity cannot
overcome the social and institutional obstacles to increasing output
of this sector.
In fact, profit maximization may undermine
effective solutions to the wires problem for two reasons. Profit
maximization has not generally been associated with the consideration
of the full range of least cost solutions to problems. Moreover, the
public will be more likely to resist bearing the negative
externalities of expanding wire capacity when there is the suspicion
that the pain is only going to make some facility owner rich.
The transmission entity must be independent of
all market participant. If it is not, it will quickly be captured by
those who would profit from the abuse of market power in the
transmission and generation markets. As a general proposition,
vertical divestiture is the only solution that eliminates the
problems of affiliate transactions. In addition to divestiture, it
now appears that a truly independent and responsible system operator
must be established. This system operator should be given the
authority to run the system solely for reliability and social
efficiency (lowest total social cost) purposes. Thus, the entity must
be rate regulated or publicly owned.
C. ESTABLISHING A
COMPETITIVE SUPPLY-SIDE
Open highways of commerce are a necessary, but
not sufficient condition for competitive markets. Markets must be
demonopolized and deconcentrated before they are deregulated or
prices will be higher than they should be. Mergers have reduced the
number of players in specific markets. Acquisitions have allowed
specific entities to gain market power. Lax law enforcement has
allowed market power to be abused.
· Markets must be deconcentrated. Market should not be deregulated until an affirmative finding of the absence of market power is made by responsible antitrust authorities and until the network is found to be irreversibly open to competition.· Ownership limits should be established.
· Additional mergers should be denied until effective market structures are defined.
· A regional cap on prices in the interstate market should be set to protect consumers from wild price swings and to prevent energy suppliers forum shopping and pursuing beggar they neighbor behaviors.
· Law enforcement must aggressively pursue abusive behaviors based on a specific set of triggers.
1. PREVENTING CONCENTRATION OF GENERATION MARKETS
One of the most urgent areas for public policy
action is developing a response to mergers. It may be useful to put a
halt to concentration through mergers until we have a better idea of
how market structures and institutions will function under the unique
conditions of the electricity industry.(82)
There is no more likely source of
supply to alleviate near term shortages.
Mergers between most utilities in the early
period of restructuring entail significant market extension that
involves monopoly and bottleneck facilities. To the extent that
utilities have had exclusive distribution territories, they are
extending the distribution monopoly. Similarly, since utilities have
owned the transmission facilities within their service territories,
most mergers involve market extension over these bottlenecks. Since
these facilities have not been subject to competition, they can be a
source of cross subsidy. Because they are bottlenecks and determine
the ability to provide service, they certainly provide the basis for
anticompetitive behaviors.
The problem of vertical integration in most
mergers is of extreme importance. Most merging utilities combine
transmission and generation assets, as well as distribution assets.
Restructuring is intended to introduce competition into the
generation market, and it is quite clear that transmission is a
bottleneck with respect to the generation market. Allowing the
extension of control over transmission assets confounds the goal of
increasing competition in generation. Competitors can be foreclosed
from the market or squeezed by price. The markets that have been
created in the early stages of restructuring have clearly
demonstrated the ability of large players to forbear from selling
into tight markets.
2. PREVENTING ABUSIVE CONDUCT
It is also important to monitor closely the
supply, bidding and pricing behavior of generation entities even in
markets where divestiture and/or open access have taken place. The
basic supply and demand conditions in electricity markets may be so
severe, that market structures that are traditionally defined as
competitive will break down situationally.
Abusive conduct must be identified,
investigated, eliminated and punished. Much closer market scrutiny
than has occurred in the first few years is necessary. Law
enforcement must be proactive, rather than reactive.
Triggers for heightened scrutiny can be drawn
directly from the analysis of industry structure. The empirical
conditions that are believed to increase the likelihood of the
exercise of market power should be set at conservative levels -
levels that lean toward protecting competition and consumers. They
can be identified for both market structure and conduct. For example,
horizontal market structure identifies the moderately concentrated
threshold at the equivalent of ten, equal-sized competitor (an HHI of
1,000). These markets should receive greater scrutiny since this
market is vulnerable to the abuse of market power. The empirical
literature identifies other potential market structural triggers. If
a vertically integrated utility controls more than 20 percent of the
bottleneck transmission assets or more accounts for more than 35
percent of demand, the scrutiny should be heightened.
On the conduct side, any vertically integrated
utility that has engaged in market tightening behavior and later
profited from actions that exploit the tightness should be subject to
greater scrutiny. The types of activities associated with market
tightening include supply tightening measures (such as taking plant
out of service on an unscheduled basis, withholding supply, executing
a swap, engaging in a two-way transaction or a daisy chain in
default) or actions that leverage the transmission bottleneck (such
as taking transmission out of service on an unscheduled basis,
declared an emergency, participating in a request for a TLR,
violating market rules).
These triggers could be linked to a much more
important set of pricing behaviors. Over the past decade, the FERC
has allowed utilities to use market-based rates based on criteria
that are not as rigorous as they should be. The FERC could reconsider
market-based rates in either of the circumstances above. It could
also use other market events, like mergers, the failure to
participate in a regional transmission organization, etc. as a
circumstance to review market-based rates.
3. PREVENTING MARKETS FROM OVERHEATING
Consumers express a strong commitment to
reliability and an aversion to price shocks. It may be difficult to
accomplish both goals at historic price levels in unfettered
commodity markets but that is the baseline against which
"competition" will be judged. The most obvious means for preventing
the overheating of markets is to have adequate reserve margins.
However, in a competitive market, it is not clear that any
supply-side entity has an interest in carrying excess capacity.
Therefore, mechanisms to respond to spikes are necessary as well.
We do not believe that residential consumers
want to see their prices tracking the commodity price of electricity
or to be forced to evaluate and implement complex hedging instrument
alternatives. For firm residential and small business customers, it
may be more important to develop programs that let them enjoy stable
prices without sending utilities plunging into markets to avoid
blackouts. Proposals to build peaking reserves at stabilized prices
become attractive if markets are going to be extremely volatile.
Distributed generation could provide a source of reserves on which
consumers could rely to prevent price spikes. Aggregators could
provide this function.
Not only do policymakers have an obligation to
do a much better job of laying the foundation for competition before
they throw the doors open, they have an obligation to monitor market
performance closely, so that rapid responses can be offered to
abusive events. Having experienced repeated spikes, policymakers
should also implement a series of circuit breakers to prevent the
sort of abuse that has occurred. These should remain in place until
regulators can affirmatively conclude that market structures are
functioning in a manner that is likely to prevent such abuse.
The most obvious circuit breaker is a price
ceiling or cap that simply does not allow trades to take place at
prices above a certain level. This is generally considered the most
extreme measure.
At some point, the FERC could declare that
prices above certain levels are not deemed just and reasonable and
therefore, market based rates are suspended. The transactions could
be allowed to move forward, but the final price would be subject to
adjudication. Other circuit breakers can be utilized before a cap is
imposed. For example, trading could be suspended for a period (as is
the practice with the stock market). Unfortunately, since the
physical movement of electricity cannot be suspended, nor is that
necessarily desirable, suspension of trading could be tricky.
D. FREEING THE DEMAND SIDE
WITHOUT PUNISHING SMALL CONSUMERS
1. ACCOMODATING DEMAND
For policy purposes, this paper emphasizes the
supply-side of the market and the highways of commerce as the target.
There are both economic and political reasons to do so.
Economically, growing electricity demand is an
exogenous factor. The growth of digital economy indicates a
resurgence of American economic superiority and it is absurd to
suggest that growth should be slowed because of the failure of supply
to expand sufficiently. While demand has grown, it is the failure of
the supply-side to deliver adequate capacity that has fueled the
problems in the market.
Politically, residential and small consumers
have generally not been vigorous supporters of restructuring and they
are not likely to support demand-side changes that place significant
burdens on them until generation and transmission have been
thoroughly reformed. As noted in the introduction, they have been
highly critical of the entire undertaking. If the only way to make
electricity deregulation work is to punish small consumers, those
customer classes may well vote to go back to the old system.
Nevertheless, there are demand side policies that can assist the
market, without punishing small consumers.
2. CREATING RESPONSIVENESS
Unless consumers have the ability to express
their demand in an effective manner, price signals will be
meaningless. Rules for aggregating small consumer demand have been
hostile or neutral, when they must be favorable. Opt-out aggregation
should be required to facilitate small consumer participation in the
market. Distributed generation should be the most highly valued
resource, since it saves on both generation and transmission
resources, both of which are in short supply. Favorable treatment of
distributed generation should be implemented including streamlined
interconnection and payment at the top of the market.
At the same time, there is no need to punish
consumers with high prices to which they have little short term
response. Price caps on retail rates should be maintained until
markets are fully competitive.
More effective programs for short-term
reductions in demand among commercial and industrial customers must
be developed. Making interruptible rates more effective for those who
are interested, and facilitating aggregation or other forms of
participation, may elicit more demand reduction. Interruptible
customers must feel they are getting a fair chance to benefit and
fair value from the interruption. Interruptible rates based on a
regulated system that did not contemplate frequent interruptions may
be inadequate. Rewards for releasing power need to reflect the higher
prices being paid at peak.
· Given the greater frequency and higher prices occurring in the marketplace, new rules on who is cut back and who is not and how customers are compensated are needed.· Indeed, in the "market context," large industrial and commercial customers would be responsive to a market in curtailment.
· However, the allocation of fixed costs, for which interruptible customers are responsible, should not burden firm sales customers unfairly.

(9) Defenders of restructuring first tried to shrug off price spikes and quality problems as accidents caused by a few technological breakdowns interacting with extraordinarily high demand ("As Might be Expected, Any Lesson to be Learned from the June Power Crisis and Price Spikes Depend Upon Whom You Ask," Foster Electric Report, No 145, August 5, 1998, quoting, AEP, p. 15; FERC, Staff Report, p. 4-13). As problems persisted, they have shifted the blame to a transitory shortage of supply or bad rules in a few markets (Bill Briar, Talk of The Nation, August, 10, 2000). Given high enough prices, they claim a little patience will call forth new supplies that will solve the problem. In fact, some have argued that prices as high as $25,000 per megawatt hour are justified (see Michaels, Robert J. and Jerry Ellig, Electricity Passes the Market Test (Mercatus Center, October 19. Enron Power Marketing, Inc., Analysis of the Midwestern Electricity Price Spikes of Late June 1998, (Enron), p. 2). An analogous response for the summer 2000 problems in California can be found in Electric Power Supply Association, Califronia: The Real Story, September 11, 2000.
(10) In addition to the analysis of the California problem, cited above, other problems in the industry have attracted a great deal of attention. Three regulatory bodies looked at the 1998 price spikes in various parts of the country - the Federal Energy Regulatory Commission (FERC, Staff Report). Public Utilities Commission of Ohio Report, Ohio's Electric Market: June 22-26, 1998, What Happened and Why: A Report to the Ohio General Assembly (Columbus, Oh; 1998) (Hereafter, Ohio Report). Bohn, Roger E., Alvin K. Klevorick and Charles G. Stalon, Market Monitoring Committee of the California Power Exchange, Report on Market Issues in the California Power Exchange Energy Markets (August 17, 1998) (Hereafter Cal, Report). The Department of Energy looked the 1999 reliability problem indicated by the outages (U.S. Department of Energy, Interim Report of the U.S. Department of Energy's Power Outage Supply Study Team, January 1999) (Hereafter, DOE Outages). It also examined market structural problems (Department of Energy, Horizontal Market Power in Restructured Electricity Markets, March 2000 (hereafter, DOE Market Power), Energy Information Administration, The Changing Structure of the Electric Power Industry 1999: Mergers and Other Corporate Combinations, December 1999 (Hereafter, DOE Mergers)). and the difficulties that utilities created for the expansion of supply through distributed generation (Alderfer, R. Brent, M. Monika Eldridge, and Thomas J. Starrs, Making Connections: Case Studies of Interconnection Barriers and their Impact on Distributed Power Projects (National Renewable Energy Laboratory, May 2000) (hereafter Connections).
(11) FERC, Staff Report, p. 3-19, estimates a net transfer of revenues (net losses by some, net gains by others) of approximately $300 million. Five entities accounted for almost three-quarters of the losses ($215 million). Wolak, Frank, Harvard Energy Project estimates above-cost pricing of $800 million in 1999.

(17) In analyzing market structure
and prescribing public policy we apply the structure, conduct
performance (SCP) view of economic activity (see Scherer, F. M. and
David Ross, Industrial Market Structure and Economic Performance
(Boston, Houghton Mifflin: 1990). The elements of the approach can be
described as follows, pp. 4-5. In SCP analysis the central concern is
with market performance, since that is the outcome that affects
consumers most directly. The concept of performance is multifaceted.
It includes both efficiency and fairness. The measures of performance
to which we traditionally look are pricing, quality and profits.
Pricing and profits address both efficiency and fairness. They are
the most direct measure of how society's wealth is being allocated
and distributed. The performance of industries is determined by a
number of factors, most directly the conduct of market participants.
Conduct is primarily a product of other factors. Conduct is affected
and circumscribed by market structure. Market structure includes an
analysis of the number and size of the firms in the industry, their
cost characteristics and barriers to entry, as well as the basic
conditions of supply and demand.
We begin with the fundamental proposition that what society wants from producers of goods and services is good performance. Good performance is multidimensional Decisions as to what, how much and how to produce should be efficient in two respects: Scarce resources should not be wasted, and production decisions should be responsive qualitatively and quantitatively to consumer demands.
The operations of producers should be progressive, taking advantage of opportunities opened up by science and technology to increase output per unit of input and to provide consumers with superior new products, in both ways contributing to the long-run growth of real income per person. The operation of producers should facilitate stable full employment of resources The distribution of income should be equitable. Equity is notoriously difficult to define, but it implies at least that producers do not secure rewards in excess of what is needed to call forth the amount of services supplied.
Performance in particular industries or markets is said to depend upon the conduct of sellers and buyers in such matters as pricing policies and practices, overt and taciturn interfirm cooperation, product line and advertising strategies, research and develop-ment commitments, investment in production facilities, legal tactics (e. g. enforcing patent rights), and so on.
Conduct depends in turn upon the structure of the relevant market, embracing such features as the number and size distribution of buyers and sellers, the degree of physical or subjective differ-entiation prevailing among competing seller's products, the presence or absence of barriers to entry of new firms, the ratio of fixed to total costs in the short run for a typical firm, the degree to which firms are vertical-ly integrated from raw material production to retail distribution and the amount of diver-sity or conglomerateness characterizing individual firms' product lines.
Market structure and conduct are also influenced by various basic conditions. For example, on the supply side, basic conditions include the location and ownership of essential raw materials; the characteristics of the available technology; the degree of work force unionization; the durability of the product; the time pattern of production; the value/weight characteristics of the product an so on. A list of significant basic conditions on the demand side must include at least the price elasticity of demand at various prices; the availability of (and cross elasticity of demand for) substitute products; the rate of growth and variability over time of demand; the method employed by buyers in purchasing; and the marketing characteristics of the product sold.
