Blackouts Hit California Again! : LUSENET : Grassroots Information Coordination Center (GICC) : One Thread

While on solar power again, with the "clock" ticking . . .



The California Independent System Operator is implementing Stage 3 of the Electrical Emergency Plan - Load Interruptions in order to maintain grid integrity and reliability.

The CAISO is continuing to request additional Supplemental Energy bids from Market Participants, out-of-market energy and emergency energy from all available sources during this period. The CAISO is requesting energy conservation during this period.

Reasons as stated on the Stage 3 notice.

The total MW amount of FIRM LOAD requested to be interrupted is: 400 MW's From 05/08/2001 15:10 with a potential restoration at 05/08/2001 21:59

PG&E 198.4 MW SCE 168 MW SDG&E 29.6 MW PASADENA 1.6 MW VERNON 2.4 MW

Participating Transmission Owners are to notify the Utility Distribution Companies within their operational areas.

Notice issued at: 05/08/2001 15:17

The system conditions described in this communication are dynamic and subject to change. While the ISO has attempted to reflect the most current, accurate information available in preparing this notice, system conditions may change suddenly with little or no notice

Here is the latest ISO chart. Note it still says stage 2.????

Now I understand, Back to stage 2 at 5:15.

Blackouts Ordered For Second Straight Day

Operators Cut Enough Power For 300,000 Homes SACRAMENTO, 8:36 p.m. EDT May 8, 2001 -- California grid operators cut enough power for 300,000 homes Tuesday afternoon, saying that hot temperatures and scarce power left supplies short of demand for a second straight day.

A Stage Three was declared at about 3:10 p.m., according to a spokesman, because demand for power continued to climb despite calls for conservation during the warm weather.

The blackouts were called off at 5:15 p.m., said Jim McIntosh, ISO's director of operations. But ISO officials said they expected similar problems Wednesday.

Officials reported earlier Tuesday that they were close to declaring a Stage Three electrical emergency and asked industrial users to cut their power use to relieve demand. But it was not enough to avoid the blackouts.

The ISO, which regulates power distribution in the state, is urging people to conserve energy as much as possible.

A Stage One emergency was declared at 8:15 a.m., followed by a Stage Two alert at 11:15 a.m. and the Stage Three about four hours later. It is expected to last until midnight.

Peak demand is expected at around 4 p.m. at 34,469 megawatts.

High temperatures, leading to more air conditioning use and a loss of transmission due to planned and unexpected plant maintenance are partly to blame for today's power emergency.

"We seem to be seeing a lack of conservation today," a spokesman said. "We knew that May and June were going to be tough months." california-76086320010508-170522.html
