Judge Dismisses Suit Against AEP over Cook Nuke

LCG, Jan. 4, 2002--American Electric Power Co. Inc. said yesterday that a federal court judge had dismissed "with prejudice" a class action suit that alleged AEP misled investors about problems at its Cook nuclear plant in Michigan.

According to AEP, the suit was dismissed by Judge James Graham in U.S. District Court in the southern district of Ohio on December 26. The suit claimed that the utility issued false and misleading statements about conditions at the 2,110 megawatt, two-unit plant to artificially inflate the company's stock price in order to proceed with the acquisition of Dallas-based utility Central and South West Corp.

Both reactors at the D.C. Cook plant near Benton Harbor, Mich., were shut down in September 1997 for what appeared at the time to be a short maintenance outage to repair problems with their emergency cooling systems.

It was found that the cooling systems, which are dependent on thousands of pounds of ice contained in hundreds of baskets, was contaminated with debris from disintegrating material. Thus began three years of melting ice and rebuilding ice baskets.

If AEP was ever overly optimistic about Cook, it was in the early stages of the long outage, when the company repeatedly issued press releases stating it hoped to restart the reactors "shortly." As the outage drew on, AEP quit making predictions.

In 2000, as the company began to see an end to its ice problems, it said it would likely restart Unit 2 in June of that year and follow with Unit 1 later that year. During this same period in 2000, AEP completed its acquisition of Central and South West Corp.
