Chickens coming home to roost?? California power grid overwhelmed
Regarding the ongoing thread about need for power, power production
alternative risks, etc., etc. copied below is an AP story running today
which reviews the electricity alert declared by California on Thursday. This
article makes for interesting reading. The California regulatory structure
and assorted environmental activists can now take credit for the various
conservation measures now being implemented there such as shutting down water
pumps on major distribution lines, shutting off the lights at Intel, and
getting ready for rolling hourlong blackouts. Chicken little may have
something to squawk about now, but it's not the theoretical effect of a
fraction of a milliRem projected 10,000 years in the future from nuclear
waste storage at Ward Valley or some other aspect of the nuclear fuel cycle.

California Declares Power Emergency
By JOHN HOWARD
Associated Press Writer
SACRAMENTO, Calif. (AP) -- California declared an unprecedented
electricity alert Thursday after its overwhelmed power grid, crippled by
idled power plants and scant supplies, struggled to meet demand.
Hundreds of companies were ordered to cut back on electricity use, but
there were no immediate "rolling blackouts'' that could affect thousands of
homes and businesses across the state.
Instead, huge state and federal pumps that move water from Northern
California to other parts of the state were temporarily shut down to save
power.
"We're hoping that with these resources we can avoid the blackouts,''
said Lorie O'Donley, a spokeswoman for the Independent System Operator, the
power grid manager.
Another spokeswoman, Stephanie McCorkle, said the state's first Stage
Three alert, covering 85 percent of California and its 34 million residents,
would remain in effect until 1 a.m. EST. If power reserves are exhausted,
hourlong blackouts were likely to begin.
California has had isolated blackouts in the past, but never before
endured controlled, widespread outages ordered by authorities to protect the
state's power grid.
Demand reached 31,600 megawatts Thursday evening, nearly the maximum
available, and reserves dipped below 1,000 megawatts -- about enough
electricity for 1 million homes.
The power crunch -- which hit even before winter had begun -- has been
blamed on cold weather in the Northwest, the shutdown of some power plants
for repairs and the effects of utility deregulation in California.
With supplies of electricity running perilously low, California
officials declared a Stage Two emergency at 4 a.m. Thursday. It was the
fourth such declaration in as many days and the eighth in three weeks.
Under the Stage Two emergency, hundreds of companies that had signed
"interruptible'' service contracts in exchange for huge rebates were ordered
to reduce or shut down their power. Others awaited notification to do
likewise.
Computer chip manufacturer Intel stood ready to turn off 50 percent of
the lights at its 6,500-employee installation in Folsom.
"If that's not enough, we'll take the lights down 100 percent and work
in the dark,'' Intel spokesman Bill Mueller said.
A Stage Two emergency is declared when power reserves fall -- or are
expected to fall -- below 5 percent. California had never before had a
statewide Stage Three emergency, which is declared when reserves fall below
1.5 percent.
The ISO said a 500-megawatt power plant unexpectedly went down Thursday
afternoon, further stressing the system. The power manager also said
utilities, which try to buy power at least a day in advance to obtain the
best possible price, were buying power with just 10 minutes of lead time as
supplies dwindled.
The alerts are the latest in a series of problems to bedevil
California's deregulated electricity system.
The phased-in deregulation of California's $20 billion electrical power
industry was supposed to lower prices by creating greater competition. But
demand for electricity has outstripped supply, in part because of a growing
population and a booming high-tech economy.
Electricity is also in short supply because energy companies held off
building new power plants while deregulation was in the planning stages. In
addition, deregulation has forced utilities to sell off their
power-generating assets, such as dams and plants, and import electricity from
neighboring states, where power demand is high right now because of a cold
snap.
Earlier this week, energy companies and state officials asked
Californians to delay turning on their Christmas lights until well after
nightfall and to keep thermostats set at 68 degrees. After lighting the
Christmas tree at the state Capitol, Gov. Gray Davis quickly pulled the plug
to conserve energy.
California inspectors have launched surprise inspections of power
plants that have closed for repairs to see whether the shutdowns were
deliberate attempts to drive up costs.
Shutdowns were part of the reason that one-quarter of the system's
capacity was down on Wednesday by 11,000 megawatts, enough to supply 11
million homes. Of that amount, state officials said, 4,000 megawatts were
from plant breakdowns.
