The looming bankruptcy of the nation’s largest energy company shouldn’t affect Iowans’ electric bills according to utility experts. The once-mighty Enron has massive debt, the price of its stock has tanked and a proposed merger has collapsed. Alliant Energy spokesman Dan Presser says their Iowa consumers shouldn’t worry the Enron situation means utility prices will spike.Presser says Alliant generates most of the power its Iowa consumers use, so customers’ bills should not be effected by the Enron situation. MidAmerican Energy spokesman Kevin Waetke says MidAmerican has purchased natural gas and electricity from Enron. Waetke says it’s a very small buy, so Enron’s financial condition should have little or no impact for MidAmerican’s Iowa customers.
