Cal-ISO Calls 'Stage 2' Power Emergency for Third Day

LCG, Nov. 16, 2000--The California Independent System Operator yesterday declared a "Stage 2" power emergency, forcing the state's utilities to shed load for the third straight day. The ISO said it would need customers with interruptible service contracts to reduce demand by 1,400 megawatts late yesterday afternoon.

All summer, Cal-ISO scrambled to find 44,000 megawatts of power and this week it is having trouble coming up with 33,000 megawatts because about 12,000 megawatts worth of power plants are shut down for maintenance and repair after running non-stop for several months.

The problem was exacerbated by a cold snap early this week that boosted demand by customers who use electricity for heat. The cold weather also affected the Pacific Northwest, reducing the amount of power that was available for import to California.

In addition, at this time of the year the streams of the Sierra Nevadas are nearly dry, reducing the amount of hydroelectric power available in the state.
