GenOn Energy will permanently close its 482 MW Potomac River Generating Station near Washington, D.C. by 2012.
As part of the agreement, GenOn agreed to retire the plant by Oct. 1, 2012. If the plant is needed beyond that date for reliability, it will retire as soon as it is no longer needed. GenOn will coordinate with PJM Interconnection, Potomac Electric Power Co. and local government regulators for necessary notifications and approvals.
The city will release around $32 million currently held in escrow set aside to pay for additional emissions controls at the plant. The emissions controls were the result of a 2008 agreement between GenOn and the city of Alexandria, Va.
The plant has been in operation since 1949 and uses both coal and oil as a generating source.
