Connecticut Plant Trips Off Line in Heat Wave

LCG, August 14, 2002-A 400 MW Connecticut plant tripped off line today, straining New England electric capacity.

Bridgeport Harbor plant managers said that an electrical problem in Unit 3 led to a small leak of oil and hydrogen. The subsequent small and short-lived fire caused no injury to workers or the plant.

The Bridgeport Harbor 158 MW Unit 2 was also shut down briefly as a precaution but is now back on line.

Plant officials do not know when Unit 3 will go back on line as the exact cause of failure is as yet unknown.

Wisconsin Energy Corp. unit Wisvest, which owns the plant, has agreed to sell it to PSEG Energy for roughly $280 million.
