`Purpa' Power: Carter-Era Law Keeps
Price of Electricity Up In Spite of a Surplus --- Utilities Must Buy Output Of
Alternative Producers At High Fixed Rates --- Sun, Wind and Cattle
Manure MESQUITE LAKE RESOURCE FACILITY in
California successfully generated electricity from cattle manure in 1994, and
shut down only after its contract to sell power to Southern California Edison
was bought out. A page-one article last Wednesday about alternative-energy
sources incorrectly stated the plant ceased running in January 1993. Also,
although the article said the idea of making fertilizer hadn't panned out, the
facility's owners do plan to process the plant's ash residue into fertilizer.

Remember alternative energy? It's the
solution that won't die for the problem that did.
The problem was the price of oil, which
seemed certain to rise to $100 a barrel. Enter the Public Utility Regulatory
Policies Act of 1978, or Purpa, meant to encourage alternative sources of
electricity. Part of extensive energy legislation passed during the Carter
administration, it provided a system of generous payments to independent power
producers and compelled utilities to buy the power. Oil prices soon plunged, and the energy
crisis receded. Purpa, however, remains, and its legacy is a curious and costly
collection of power plants: a Mojave Desert solar field whose operators say dust
from a 1991 volcano obscures the sun's rays; an incinerator that turned to a
rusty mess after its chosen fuel, cattle manure, was muddied by pounding rains;
and a California windmill farm that creates such a draft that golden eagles are
sucked in and killed.
Elsewhere, the law produced highly
efficient hydroelectric and natural-gas power plants but provided bizarre
economic incentives. Some Pennsylvania and New York plants, for instance, get
paid so handsomely for electricity in early years and so much less later on that
the developer publicly contemplates walking away from them after only 15 years
of operation.
In all, the hundreds of power plants
qualified under Purpa now represent, in effect, a $37 billion roadblock to lower
electricity prices. That is how much the plants will receive from utilities
through the year 2000, over and above estimated market prices, as calculated by
Resource Data International Inc., a consulting firm in Boulder, Colo. The U.S.,
meanwhile, has a glut of generating capacity. This glut plus major advances in
turbine technology would, in an unregulated market, be driving electricity
prices sharply downward in many regions now.
Of course, it isn't as though Purpa is the
only thing keeping power prices from falling. Resource Data estimates that
utilities have another $175 billion of deadwood on their balance sheets that
regulators are letting them slowly recover from customers. This includes
investments in nuclear power plants, long-term coal contracts at above-market
prices and other costs.
Many utilities are thus highly vulnerable
to competition, as state and federal officials begin to map out deregulation of
the $200 billion-a-year electricity business.
But, well fed by Purpa, independent power
producers aren't acting like the scrappy newcomers one might expect. Rather than
argue for immediate price decontrol, they are lobbying to protect their
lucrative power contracts under Purpa, and are perfectly happy to see utilities
continue to recover their bloated costs as well. "We don't want our shareholders
to suffer millions and billions of dollars of losses," says Lawrence W. Plitch,
a vice president at WMX Technologies Inc.'s independent power unit. "And we
wouldn't expect utilities' [shareholders] to, either."
The independents and utilities each argue
that their costs were incurred in good faith, that is, in the assumption that
the industry's nearly 100-year-old regulatory system would endure. That system
imposes nearly all costs on customers, in exchange for reliable supply. It would
be unfair, they say, to abruptly subject the industry to competition.
Critics, however, see this regulatory
system as a continuing bailout of bad business decisions. They argue that
pricing decontrol, though it could bankrupt some big utilities, would be a boon
to the economy. A cut of one cent per kilowatt hour from the national average of
about seven cents would save U.S. industry and consumers roughly $28 billion a
year.
"Ratepayers have been buying overpriced
electricity," says Robert Michaels, an economics professor at
California State University at Fullerton and a consultant to companies
that favor deregulation. "If we have a chance to save even $20 billion a year,
let's do it."
Twenty-five years ago, the idea of costly
electricity would have seemed absurd. Cheap fuel and plant efficiencies had
steeply lowered residential electricity prices -- to 2.1 cents a kilowatt hour
from about 20 cents early in the century. Nuclear power seemed to promise still
more efficiency. Experts spoke of power becoming "too cheap to meter."
Then things went haywire. Many nuclear
plants became expensive boondoggles. Oil prices surged. Interest rates did too,
choking the capital-intensive industry. And some utilities, desperate to
guarantee fuel supplies, signed coal contracts that, in hindsight, are far
overpriced. Residential rates nearly doubled by 1978 and were headed much
higher.
All of that, plus growing concern about
pollution, made alternative energy look good. But the law that Congress passed
to encourage it didn't merely make utilities buy the output of
alternative-energy plants at market prices; the price it set was utilities'
"avoided cost" -- the amount per kilowatt hour it would cost them to generate
the power themselves. The calculations might include the cost of building a new
power plant. Long-term contracts had to be signed with the independents, with
prices based on forecasts of future generating costs.
Such estimates were often far from the
mark. One California forecast had oil hitting $189 a barrel by 2000; it's at $20
today. A 1981 Southern California Edison study estimated the utility's 1995
avoided cost would be 16.73 cents a kilowatt hour; today, power changes hands on
the wholesale market at two to three cents in large quantities. The Edison
forecast would have translated into an average household electric bill of $192 a
month in 1995 and $300 by 2000; today's average bill is about $65.
Meanwhile, some utilities, used to running
monopolies, balked at buying power. So several states, notably California and
New York, turbocharged Purpa. "They did something so totally foreign to a
market," says Bill Booth, a Federal Energy Regulatory Commission official.
"Instead of determining needed capacity and letting the market determine price,
they set a price and allowed unlimited capacity."
It was a great deal, and word got around.
Utilities intermittently tried to scale back, or even kill, Purpa's largess, but
they had little credibility because of their own costly mistakes. Independent
power producers built more new generating capacity than did utilities. Plants
that qualified under Purpa now account for 7% of the electricity market.
How have these plants fared?
Solar power was one of the types Purpa
encouraged. Promoters sold over $1 billion in partnership interests to finance
big solar fields near Barstow, Calif., thanks not only to Purpa but also to
state tax breaks. Today, the desert sun bounces off arrays of mirrors to heat
piping filled with oil. The oil heats water into steam to power a turbine. On a
bright day, with computers precisely aligning the mirrors, it is a brilliant
spectacle.
But costly. The Southern California Edison
unit of SCEcorp must pay an average of 15 cents a kilowatt hour to buy solar
power, perhaps five times what it would cost on the wholesale market.
But the utility doesn't suffer. Edison
passes the cost on to its customers. It's part of the $800 million above market
prices that Edison pays for power each year because of Purpa.
The solar fields aren't working as well as
hoped. Operators say this is because the atmosphere still contains fallout from
the eruption of Mount Pinatubo in the Philippines four years ago.
At one field, 300 acres operated by Daggett
Leasing Corp., 20% of the mirrors are broken. Daggett says they aren't worth
replacing. High operating costs make the plant uneconomical, but the owners
don't want investors' past tax benefits to be reversed. "It makes sense to keep
going no matter what," says Eric Wills, Daggett's president.
Beyond sunshine, Purpa looks favorably on a
broad category of fuels known as biomass: nut shells orchard prunings, household
trash and methane drawn out of garbage dumps.
Also, cattle manure. As it hits the ground,
however, this particular fuel is about 85% moisture. Worse, it gets stepped on
and mixed with dirt, which doesn't burn. It is so corrosive it chews through the
steel, porcelain and aluminum of the world's only commercial-scale manure-fired
power plant: Mesquite Lake Resource Facility in El Centro, Calif. The plant was
built in 1985 for $49 million.
Operators struggled for years to keep the
manure plant lighted. Notions that the resulting ash would make great fertilizer
didn't pan out; 350,000 tons of the stuff, fine as talc, piled up out back.
Then, in January 1993, record rains turned
the normally tidy cattle feedlots of the El Centro area into muddy latrines.
When the skies cleared and some of the muck was tried as fuel, it choked the
plant out for good.
With it shut down, the electricity payments
from Southern California Edison ceased. But recently the plant's owners
negotiated a buyout of their 30-year contract that could bring them another $10
million from Edison and, hence, from Edison's electricity customers.
Wind has problems, too. The big wind farm
in the Altamont Pass in California also was a financial bust for utility
customers by the time it was completed, with Pacific Gas & Electric Co.
paying a pricey 11 cents a kilowatt hour for the electricity. But the wind
turbines -- thousands of them atop the hills east of San Francisco -- became a
vivid symbol of the potential for environmentally friendly power.
That image has taken a bruising lately as a
freezer at a U.S. Fish and Wildlife Service office fills up with carcasses of
golden eagles, hawks and kestrels found at the site. The pass, which funnels
cool coastal air into the hot Central Valley, is home to one of North America's
largest populations of golden eagles, which find the windmills' latticed towers
convenient perches for spotting ground squirrels.
One study concluded that more than 500
raptors were killed in the wind farm over two years, including 78 golden eagles.
How? Probably they were pulled off their perch and into massive blades that, at
the tip, spin at up to 200 miles per hour. Or, researchers say, maybe they flew
right into the blades.
The biggest windmill operator, San
Francisco's Kenetech Corp., launched a $2 million study aimed at preventing bird
deaths plus a vigorous public-relations effort. It is painting the blades,
hoping birds will see them. It is perch-proofing the towers. And, hoping to
learn more about bird collisions, it brought in homing pigeons that researchers
can observe flying through the Altamont Pass wind farm.
Pigeons aren't eagles, though, and a Fish
and Wildlife agent, Cynthia Struzik, questions what help they will be. "The only
similarity is that they all fly," she wrote to local officials.
Kenetech also has questioned the body
count. It put out a report citing a study saying 57 million birds of all kinds
are killed every year in collisions with cars and trucks. What does that have to
do with eagles? "Nothing," concedes Clarence Grebey, Kenetech's PR chief. "There
was internal debate about putting that in there."
Besides wind, solar and such, power plants
fired by ordinary fossil fuels such as natural gas can qualify under Purpa if
they are "cogenerators," producing small amounts of power from steam that
normally would be vented. Companies can use the hot air to heat a factory or, as
at a Procter & Gamble Co. paper mill in Oxnard, Calif., to blow Charmin
bathroom tissue dry.
Selling most of the power to the local
utility at above-market rates, the factories in effect are subsidized by utility
customers. Oxnard wouldn't be economical for P&G without its power sales to
Southern California Edison at about six cents a kilowatt hour. "We wouldn't even
be here," says Stacey Roscoe, the plant's energy business manager.
Use of steam power representing just 5% of
a generating plant's total energy output qualifies as cogeneration. So power
contracts are sometimes secured in partnership with minor so-called steam hosts
such as coin laundries, civic swimming pools and greenhouses.
Utilities say the steam hosts are sometimes
an afterthought. Officials at Medina Power Co. in Allegany, N.Y., told federal
regulators in 1990 that a 13.8-megawatt plant's steam host would be a
distilled-water plant. Then in 1992, just a month before the power plant began
operating, Medina told regulators that the steam would be used to heat an
eight-acre greenhouse.
An official of Niagara Mohawk Power Corp.
in Syracuse, N.Y. -- the utility required to buy Medina's electricity -- visited
the Medina site more than a year later and there still wasn't a greenhouse, it
said in a regulatory filing. It is seeking to strip Medina's Purpa
qualification. Medina officials won't comment.
An even stranger situation arises from
payment structures provided by some states. Consider the case of Sithe Energies
Inc., an independent producer controlled by Compagnie Generale des Eaux of
France. It built six plants in Pennsylvania and New York for a combined $368.5
million. Yet Sithe says it may abandon them after only 15 years of operation.
The reason: contracts that heavily
front-load the payments from utilities. After an initial 15 years, the
independents would get much smaller payments or conceivably have to repay money
to utilities, while continuing to provide power.
But there is a loophole. If the future
looks bleak, the independents can simply walk away. Utilities and other
creditors would be left with only the power plant.
The utility buying power from Sithe's New
York plants, again Niagara Mohawk, has similar contracts with other power
producers. It estimates that overpayments -- the amounts that would be due back
to the utility -- could total $7.3 billion, and asked state regulators to
require independents to post collateral. The request was rejected.
Niagara Mohawk estimates it pays $400
million a year above market rates for independent power, sometimes reselling the
power at distress prices of less than one cent per kilowatt hour.
Utilities in several states have mounted
legal challenges to their contracts with independents, but mostly failed. They
are also trying to buy out some contracts; some independent plants' operating
costs are so high that it can pay them to agree to close down and take reduced
payments.
In such a case, the utility saves, too; if
it needs the electricity the plant was producing, it can buy it elsewhere more
cheaply.
The big utilities, however, had a hand in
creating the Purpa problem. That's because many of them built independent power
plants themselves. Until recently Niagara Mohawk owned a unit that had stakes in
25 projects; it has sold it to another utility, CMS Energy Corp. in Dearborn,
Mich. PG&E owns Purpa-qualified projects through a joint venture.
SCEcorp, Southern California Edison's
parent, was perhaps boldest. It sold independent power to itself.
It has a unit, Mission Energy Co., that
holds stakes in 13 plants that sell to Edison. Some weren't even in the
utility's service territory. The California Public Utilities Commission staff
took offense, alleging self-dealing. Edison, which denies the self-dealing
charge and says its plants were less costly than others, made a $250 million
refund to customers. It also agreed in 1992 not to do any more deals with
Mission.
Mr. Michaels, the economics
professor, has watched, amazed that a law designed to give a modest boost to
alternative power has spawned such a big and costly system of power plants. "Had
anybody expected Purpa to lead to all this," he suspects, "it never would have
been passed."
