State Runs Short of Power when Montana Plant Trips

LCG, Sept. 21, 2000The California Independent System Operator was forced to declare yet another electric power emergency yesterday when a power plant a thousand miles away tripped off line, taking 1,300 megawatts with it.

Temperatures in the Golden State had begun to moderate yesterday from the record highs that had gripped the state all week, but California still needed imported power to meet its needs and have a little in reserve.

The Washington Public power Supply System's 1,150 megawatt nuclear power plant near Pasco, Wash. had shut down because of a malfunction on Tuesday, so the availability of imported power was already tight. Then yesterday, units 1, 2 and 3 of the big Colstrip power plant in eastern Montana went off line and suddenly there was no power to be had from the Pacific Northwest.

Workers at Colstrip, which is now owned by the parent company for Pennsylvania Power & Light Co., struggled with the plant and were able to get Unit 2 restarted at around 10:00 p.m. but it tripped off line fifteen minutes later, indicating significant problems.

Colstrip 2 was back on line at about 3:00 a.m. today, but a spokesman for PPL Corp. declined to comment on the plant's status, saying that such information was held confidential for competitive reasons.

It's cooler today, with scattered clouds over the San Francisco Bay Area.
