U.S. Secretary of Energy Chris Wright on Aug. 21 issued an emergency order directing the PJM Interconnection, in coordination with Constellation Energy Corporation, to ensure Units 3 and 4 of the Eddystone Generating Station in Pennsylvania remain available "to operate and to employ economic dispatch to minimize costs for the American people."
The units were originally slated to shut down on May 31, 2025. This order is in effect beginning on August 23, 2026, through November 20, 2026.
Wright issued similar orders to ensure the units are available in 2025 and 2026.
Eddystone Generating Station is owned and operated by Constellation. It is a six-unit, 820-megawatt power plant, located on the Delaware River in Eddystone, Pennsylvania, just south of Philadelphia.
Eddystone Units 3 and 4, each with 380 MW capacity, are subcritical steam boiler-turbine generator units that can run on either natural gas or oil, depending on market conditions. These units were installed between 1967 and 1970.
Units 10 and 20 and 30 and 40, with a total combined capacity of 60 MW, are pairs of oil fueled peaking units that run during periods of high demand. These units were installed in 1967 and 1970, respectively.
