FirstEnergy Sends Rolling Blackout Warning Again

LCG, August 21, 2003FirstEnergy Corporation said its customers may suffer rolling blackouts pending todays weather.

FirstEnergy serves 4.3 million customers in New Jersey, Ohio, and Pennsylvania and has been urging them to conserve electricity over this week as the company recovers from last weeks blackout. FirstEnergy is hoping to bring the 1,320-megawatt Perry nuclear plant on line this evening when it reaches 17 percent capacity. Currently it is running at or above 11 percent. Several reactors were shut down during the massive Northeast blackout, and this week temperatures have been on the rise.

FirstEnergy asked customers to conserve energy yesterday and managed to make it through the day without instituting rolling blackouts, although power was cut to interruptible customers in the Cleveland area. Such industrial and large commercial customers give up power in exchange for cheaper rates, and the utility says it saved between 500 and 700 megawatts yesterday by this method.

The company also expects to return three coal-fired generators to service today and has noted that no generators or lines failed yesterday.

The cause of last weeks blackout, which left 50 million people in the dark, has yet to be determined. Some officials have pointed the finger at FirstEnergys service area, but most officials say it is too early to say anything concrete.

FirstEnergy used rolling blackouts on last Friday in an effort to return to regular service.
