Houston-based Dynegy Inc. is again asking for a waiver from pollution controls at five coal-fired power plants that it wants to buy from Ameren.
Dynegy filed a petition to the Illinois Pollution Control Board more than a month after the board refused to transfer an existing waiver held by Ameren granting a five-year delay in installing soot-control equipment. The board said Dynegy must make the case on its own merit.
Ameren got the waiver after claiming a financial hardship. Dynegy says the same conditions exist if it buys the plants in Coffeen, Canton, Bartonville, Joppa and Newton, including lower electricity prices driven, in part, by competition from natural gas plants. Dynegy has said, in the past, that the purchase depends on whether the waiver is transfered.
