FOR IMMEDIATE RELEASE Contact: Stephanie McCorkle May 30, 2001 Director of Communications


(Folsom, CA) The California Independent System Operator (California ISO) declared a Stage Two Electrical Emergency today, Wednesday, May 30, 2001, at 2:00 p.m. with operating reserves dipping below five percent. A number of factors are contributing to today’s emergency condition:

--With higher than expected temperatures and the corresponding use of air conditioning units, the demand for power is trending approximately 1,200 megawatts over the forecast.

--Net imports are running at 4,000 megawatts; 3,000 less than last week.

--A total of 9,800 megawatts worth of generation remains unavailable today with power plants off-line because of preventative repairs and plant malfunctions. Consumers are asked to step up conservation efforts as the California ISO’s job of balancing the supply and demand for power becomes more challenging this afternoon and into the evening peak hours.

Demand across the California ISO Control Area is expected to peak at 36,174 megawatts around 3:00 p.m. this afternoon.

Today’s Stage Two Emergency is in effect until midnight. With the Stage Two declaration, the California ISO is able to access emergency resources that will help maintain operating reserves.
