Flooding Shuts Down More than 900 Megawatts of Power Generation Capacity in Iowa

SUGAR LAND--June 23, 2008--Researched by Industrial Info Resources (Sugar Land, Texas)--According to the majority of power station owners surveyed across Iowa's hardest-hit flood areas, the extremely high floodwaters over the past two weeks have not forced them to take generating capacity offline. However, more than 900 megawatts of capacity is offline because of the floodwaters. Companies with capacity offline due to the flood include Interstate Power &Light, a subsidiary of Alliant Energy Corporation (NYSE:LNT) (Madison, Wisconsin) with 600 megawatts offline, AmerenUE (NYSE:AEE) (Saint Louis, Missouri) with 125 megawatts offline, Cedar Falls Utilites with 100 megawatts offline, MidAmerican Energy Company, a Berkshire Hathaway (NYSE:BRK-A) company, with 80 megawatts offline, and Vinton Municipal Electric Utility with 20 megawatts offline. The timeframe for returning these plants to service depends upon the damage that has occurred, which will be assessed once the flooding has subsided.
