Diesel Problems Keep Seabrook Off-line

LCG, Dec. 15, 2000--The 1,150 megawatt Seabrook nuclear power plant in southeastern New Hampshire shut down October 21 to refuel and was expected back on-line by November 21, but continuing problems with a back-up diesel generator have prevented a restart and it appears they will continue to do so, a minority owner of the plant said yesterday.

Bay Corp Holdings Ltd., the parent company for Great Bay Power Corp. and Little Bay Power Corp., said that repairs to the diesel had been expected to be accomplished by the middle of this month, but haven't been. When mechanics tested one of the diesel generators recently, they broke it.

Seabrook is mostly owned by Northeast Utilities subsidiary Public Service Co. of New Hampshire and is operated by North Atlantic Energy Service Corp. North Atlantic is now projecting that the plant will be returned to service at the end of January.

Bay Corp got out a news release to explain the outage is costing it a lot of money for replacement power it must purchase at high rates to cover the 174 megawatts it isn't getting from Seabrook.
