Exelon Corp. has said it might have to shutter at least three of its six nuclear plants in Illinois if they can't be made profitable long-term. The Herald & Review reports the six mayors sent letters to Gov. Bruce Rauner and top state legislators saying the plants are essential to their communities.
The nuclear facilities that Exelon says could close are in Byron, Clinton and Rock Island. The company says the plants are having a hard time competing with other energy sources like wind that get tax breaks.
A report from several state agencies released last month said penalizing competitors that emit carbon dioxide could help Exelon's nuclear facilities stay open.
