DOE Orders Older Gas-Fired Power Plants Near Philly to Stay Online

| | | |
The Eddystone Generating Station is a power plant owned by Constellation Energy Corporation, located in Eddystone, PA (near Philadelphia, in Delaware County). Units 3 and 4, each with 380 MW of generation capacity, can run on either natural gas or oil. The Eddystone Units were initially scheduled for retirement on May 31, 2025, but the U.S. Department of Energy (DOE) stepped in and ordered both units to remain online and active due to emergency energy conditions in the PJM grid. The original order kept both units online and active an extra 90 days, until yesterday. DOE Secretary Chris Wright sent a new order to Constellation yesterday, extending the operation of the two units for an additional 90 days, until November 26.
