Federal task
force finds flaws in wholesale markets - Lots and lots of them

Many wholesale power buyers have had trouble signing long-term
contracts, a federal task force found in a draft report on the state of
competition (RT, 6/6).
The task force -- composed of FERC, DOE, the Justice Dept, Federal Trade
Commission and Agriculture Dept's Rural Utility Service -- could not
come up with conclusive data but found that most buyers in New York, the
Midwest and the Southeast have bought power on less than one-year
agreements (http://elibrary.ferc.gov/idmws/File_list.asp?document_id=4410239).
Buyers think that generators in RTOs don't want to sign long-term deals
because they can get higher prices in the spot market -- taking
advantage when high-priced gas-fired generation sets the price.
Market-clearing prices in RTOs set "by a subset of generators depending
on demand and transmission congestion" raises competitive concerns, the
feds argued.
A lack of liquidity -- especially beyond three years -- may be hindering
long-term pacts, the task force added.
Hedging products for that length of risk just aren't available.
Long-term pacts have been discouraged by grid congestion and the
inability of customers to get long-term rights at known prices --
particularly in RTOs, the task fore discovered.
That has hurt financing of new generation -- especially more expensive
baseload plants -- the feds found. The team found that contracts are
tough to sign outside of RTOs because buyers can't easily get
transparent information about prices and ATC.
Grid owners are in the dark too, the feds added, because they don't have
centralized data on bilateral deals -- making it tough to deal with
congestion.
Contracts for new generation are prone to regulatory risk too, the task
force reminded. Buyers, the feds said, have tried to void pacts signed
during the California energy crisis. Contracts' integrity has been
harmed too by IPPs' bankruptcies, the task force added. IPPs have sought
to break pacts due to insolvency. That can make buyers think twice
before signing future deals with IPPs.
That risk could prompt state regulators to favor utility-built
generation over merchant generation, the feds warned.
Investors have favored utilities over IPPs recently, the task forced
added, because of IPPs' credit challenges and reduced profitability.
Higher volatility in organized power markets favors utility-built
generation too, the feds observed.
Volatility means uncertain revenue streams for IPPs while utilities can
show investors a consistent cash flow from rate-base generation, the
team wrote.
Price mitigation in RTOs, the task force found, have hurt the chances
for new merchant plants to recover investments.
Price caps during scarcity create a "chicken-and-egg conundrum," the
feds reported. Caps discourage investment because generators fear not
being able to recoup costs. But the need for high scarcity prices
wouldn't exist if more generation was built and supplies didn't dwindle,
the task force discovered.
Capacity payments could, in theory, support new generation investment
because they assure builders and investors a certain level of return,
suggested the feds.
"Capacity credits might allow merchant plants to be sufficiently
profitable to survive even in competition with the generation of
formerly integrated local utilities that may have already recovered
their fixed costs," the task force argued. But the experience with
capacity payments is mixed, the feds found. Two regions-- the Southeast
and Midwest -- have seen big generation investments without capacity
payments while Northeast RTOs with capacity credits "continue to have
some difficulty attracting entry, especially in major metropolitan
areas," the task force reported.
"Unfortunately, there is no conclusive result from any of these
approaches -- no one model appears to be the perfect solution to the
problem of how to spur efficient investment with acceptable levels of
price volatility," the task force observed.
The Midwest's generation was built because of uncapped price spikes
(remember the $7,500/mwh) in the late 1990s while the Southeast saw a
rash of merchant generation because of its proximity to natural gas
fields, the task force noted. The New York ISO, the feds learned, has
been successful in getting generation built in congested areas. About
1,000 mw of new capacity is to be added this year in New York City, the
task force noted. The New York ISO is better able than ISO New England
to match locational needs with investment because the New York ISO has
clearer price signals in energy and capacity markets. The New York ISO
includes the costs of running generators in load pockets when
calculating locational prices, the team explained.
It sets too a more generous "reference price" for generators less than
three years old to help them recover costs.
Regulation is interfering with the efficient exit of old plants, the
task force noted, citing reliability must-run deals in RTOs.
Those are the worst kind of deals, the team wrote. They're outside of
the market and don't permit competition from -- or send price signals to
-- cheaper alternatives such as new generation or demand response.
Graduated capacity payments that favor new entry of efficient plants may
help get inefficient plants retired, suggested the feds.
The task force doubted whether a pay-as-bid market would produce lower
prices than the uniform clearing price used by RTOs now (RT, 3/31).
Generators are paid what they bid into the market under pay-as-bid
pricing. That's different from uniform clearing pricing where all
generators get the same price -- the marginal clearing price of the last
and thus most expensive generator that's dispatched.
Pay-as-bid pricing should not theoretically lower market-clearing prices
-- and may even raise prices -- because generators will be encouraged to
bid based on their forecasts of clearing prices rather than on marginal
costs.
Pay-as-bid pricing can harm dispatch efficiency too, the feds noted.
Uniform clearing prices will let low-cost generators get big profits
when expensive units set the clearing price, the task force conceded.
But inefficient units will get smaller returns than what they would get
under cost pricing, it added. That encourages units to cut costs and
prompts investors to build more efficient generation -- lowering prices
down the road.
The feds' draft report at first glance "appears to be a
well-constructed, balanced look at competition that highlights the
successes we've seen with restructuring as well as some areas where
improvement is needed," EPSA CEO John Shelk said.
EPSA "certainly" agrees with the task force's views on grid access that
point to a need for reform, he added.
