The US Department of Energy on Thursday said it has renewed an emergency order requiring a fossil fuel-fired Pennsylvania power plant to remain operational to address grid reliability issues in the Mid-Atlantic region.
Energy Secretary Chris Wright ordered PJM Interconnection, in coordination with Constellation Energy (CEG), to keep Units 3 and 4 of the Eddystone Generating Station available beyond their planned retirements and to use economic dispatch to limit consumer costs, the Department said in a statement.
"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," according to a document on the DOE website.
These units were initially scheduled to shut on May 31, 2025.
Wright first issued an emergency order on May 30 last year to keep the units online past their planned retirement, with subsequent orders issued later in 2025 and 2026.
"Keeping these units operational over the past year strengthened energy security in the PJM region, as demonstrated when PJM called on the units to generate electricity during heat waves that hit the region in the summer and during Winter Storm Fern," the statement said.
The units generated 26,971 megawatt-hours between June and December last year, the statement said, citing US Environmental Protection Agency data.
The order is effective from May 25 through Aug. 22.
