APRIL SHOWERS bring summer power. That's the upside all of those gloomy, rainy days. Some of that water, collected as Sierra snow pack, will flow into rivers and generate hydropower. It's one of the factors responsible for this summer's adequate power outlook, state officials say. The positive outlook comes despite the possibility a pair of natural-gas-fired power plants in the East Bay may shut down soon. Last Thursday, Mirant Corp. gave 90 days notice to state regulators that it may have to shut down a unit at its Antioch plant and another one at its Pittsburg plant if the company...

Electricity is not something most folks think about except when it's not there. But it's drawing attention from Valley communities funding a plan that may bring construction of a local power plant to generate electricity at a lower cost and improve electricity reliability for Valley residents and businesses. The proposal is by the Fresno-based Kings River Conservation District. The district is willing to build a $350 million, 500-megawatt natural gas-fired power plant to generate electricity if the 12 member communities are willing to participate. One megawatt can serve 1,000 homes with electricity. For three years, the district has been working...

RICHLAND, Wash. -- Washington state's only commercial nuclear reactor remained out of service while technicians tried to determine why an automatic shutdown system failed during a test Friday. State emergency officials said there was no release of radiation and no danger to the public. It was not immediately known when the Columbia Generating Station reactor would be restarted. The reactor, which produces power for the Northwest electricity grid, would remain out of service until crews determine what caused the problem, he said. Energy Northwest spokeswoman Heather McMurdo said lights on a control panel showed that two of 185 control rods...

For three days in a row last week, California broke all-time electricity consumption records as the mercury climbed over 90 degrees across much of the state. And this is only July. Sizzling August still lies ahead, and the record is almost certain to be broken again. ``We still haven't seen our peak for this year,'' said Jim Detmers, acting chief operating officer of the Independent System Operator, manager of much of California's power grid. The first statewide heat wave of the year has stirred fears of blackouts in California four years after the power system collapsed under the weight of...

The California ISO determines a level of load reduction that is needed to maintain grid reliability. We notify the local utilities of their share of this amount. It is up to the individual utilities to determine how they will implement the load shedding (i.e. rolling blackouts). Utility policies differ. Thus, to determine whether you will possibly be blacked out, contact your local utility. The utility schedules the curtailments and determines which portions of their grid (blocks, circuits, areas) will be blacked out and the timing of the rotation of the blackouts. The individual utilities also determine such things as blocks,...

Other Comments: The CAISO is declaring Restricted Maintenance Operations for the period 0700- 2200 today due to high loads and temperatures across the ISO control area. Yesterday/Weekend/Holiday Notable Events: At 1642 PST yesterday the CAISO requested SCE to shed 300 MW of interruptible load and 175 MW of pumping load due to the South of Lugo local area loading problem. Due to fires burning in the Southern California area, several 230-kV and 500-kV lines relayed during the 1453-1851 PST time frame which created the limitation overload. The CAISO declared a transmission emergency from 1959 through 2359 yesterday due to the...

Restricted Maintenance Operations [200401436] The ISO is anticipating high loads and temperatures across the ISO Control Area. The California ISO is declaring Restricted Maintenance Operations for the period from 07/20/2004 07:00 through 07/20/2004 22:00.

A transmission line failed in Arizona, then a substation relay malfunctioned, a major nuclear generating facility went off line and three other power plants went down like dominoes this past Monday morning. "This incident certainly had the potential to cascade out of control," said Gregg Fishman, a spokesperson for the California Independent System Operator. However, "the automatic systems that detect and react to under-frequency events worked as planned, reducing loads immediately," he said. What could have been the Western version of last August’s blackout in the Northeast was averted last Monday when automatic systems performed as planned in response to...

SANTA MONICA, Calif. -- California Attorney General Bill Lockyer filed suit Thursday against Enron Corp. and several subsidiaries for allegedly manipulating market prices during the state's 2000-01 energy crisis and costing Californians billions of dollars. The suit, filed in Alameda County Superior Court, seeks restitution and unspecified damages from the Houston-based energy giant whose trading practices are under investigation by the Justice Department. --snip--The filing comes amid the attorney general's ongoing battle with the Federal Energy Regulatory Commission to collect as much as $9 billion in refunds from energy wholesalers that officials say the state is owed to cover overcharges...

SACRAMENTO, Calif. (AP) California Attorney General Bill Lockyer has asked federal regulators to reverse a May order that demands the state pay Enron and other energy companies almost $270 million in refunds stemming from the 2000-01 energy crisis. The refunds add ``insult to injury by rewarding the sellers a second time for their market manipulation activities and predatory pricing,'' the attorney's general motion said. It was filed Monday with the Federal Energy Regulatory Commission. ----snip----- The order was particularly unfair considering ``the recent Enron tapes and so much other evidence of market manipulation by the energy generators,'' Lockyer said in...

On Monday May 3, 2004 at 1117 PDT the CAISO issued a system warning due to lack of available capacity and higher than anticipated temperatures and loads in Southern California. At 1420 the CAISO declared a Transmission Emergency. They dropped 122 MW of pump load and requested SCE to drop all available interruptible load. SDG&E had already initiated interruptible load shedding. Approximately 700-750 MW of load relief was experienced. CAISO Pump load was restored at 1741. At 2200 the CAISO terminated the Restricted Maintenance Operation. At 2359 the CAISO terminated the Transmission Emergency

<p>California grid operators suspended Enron Corp.'s trading and marketing privileges Tuesday, saying the Houston-based company failed to supply accurate data and enough collateral to cover an estimated shortfall.</p> <p>The California Independent System Operator, which manages much of the state's power grid, said the bankrupt energy company estimated that it owed $15 million to $50 million that it had underreported during 2001 and 2002.</p>

Keeping pace with strong winds and rain in the West this week, power markets swept higher. Charging natural gas prices, as well as the on-again, off-again status of Diablo Canyon's nuclear units, appeared to contribute to spot prices' upward mobility.Outages in the Path 26 area of the California Independent System Operator grid system also may have played a part in prices' performance. Cal-ISO considered calling for load curtailments in Southern California to account for the situation but eventually did not, according to reports. Systemwide, loads on the Cal-ISO grid stayed in the mid-31,000 MW range, notching up to about 32,000...
