Exelon rivals sue to block billions of dollars in subsidies


CHICAGO (AP) — Competitors of Chicago-based Exelon Corp. have filed a lawsuit opposing legislation that provides billions of dollars in subsidies to the power giant. The legislation approved in December provides $235 million annually to Exelon to keep unprofitable nuclear plants running in Clinton and the Quad Cities. More than 4 million customers of power-distributing subsidiaries ComEd and Ameren will pay more to finance the plan. The lawsuit filed Tuesday challenges the law on constitutional grounds.
