NRG Energy Inc. said it will retire three coal-fired power plants—two in Illinois and one in Delaware—next year after disappointing results in the May 2021 capacity auction for the PJM Interconnection.
NRG during its June 17 investor day presentation said about 1.6 GW of coal-fired generation would be closed, including the 682-MW Waukegan and 510-MW Will County (Romeoville) plants in Illinois, along with the 410-MW Indian River plant in Delaware. The announcement was made by Christopher Moser, NRG’s executive vice president of operations. The plants account for about 55% of NRG’s coal-fired generation capacity in PJM.
“Closing these plants was a difficult, but necessary decision,” NRG said in a statement.
Moser said the three facilities would be retired in June 2022. The clearing price for most of PJM’s service territory dropped to $50/MW-day in the 2022-23 capacity auction, down from $140/MW-day for the unconstrained regional transmission organization region in the 2021-22 capacity auction. PJM said there was a reduction of 8,175 MW of coal generation from the previous auction, when accounting for resources committed to fixed resource requirement plans.
