FERC approves Constellation waiver request on Crane restart
The Federal Energy Regulatory Commission has approved Constellation’s waiver request to transfer PJM capacity interconnection rights from one of its gas- and oil-powered plants to its Crane nuclear power plant (formerly Three Mile Island-1).
While Constellation executives previously said that an unsuccessful waiver request wouldn’t have prevented the Middletown, Pa., plant from restarting as soon as 2027, it could have impacted whether Crane could fully deliver power to the grid once it is on line. The decision, issued by FERC on June 1, likely helps facilitate Constellation’s path forward for the plant’s restart.
