Pennsylvania coal plants get lifeline as state delays closures until 2032
As Memorial Day ushers in the unofficial start of summer, soaring temperatures across Pennsylvania are already putting added strain on the electric grid. With air conditioners humming and energy demand climbing earlier than expected, state officials are looking to avoid the kinds of reliability concerns that have triggered warnings across the PJM network. That concern is a major reason two of Pennsylvania’s largest coal-fired power plants, once scheduled to close in 2028, are now expected to remain operational through 2032 under a proposed agreement with state regulators.
The Keystone and Conemaugh generating stations in western Pennsylvania would stay online for four additional years under a consent decree negotiated between plant operators and the Pennsylvania Department of Environmental Protection (DEP). Together, the two facilities are among the largest coal-burning power plants in the Commonwealth and provide roughly 3,400 MW of baseload electricity.
“Pennsylvanians are worried about rising energy costs right now and they need reliable, affordable sources of power to ensure our homes and businesses can keep the lights on without breaking the bank,” said Governor Josh Shapiro. “I’m an all-of-the-above energy Governor, and by upgrading the environmental controls at the Keystone and Conemaugh Generating Stations to keep them operating for longer, we will protect energy jobs and ensure Pennsylvania generates enough energy to support the regional grid while reducing their impact on our environment.”
Under the proposed agreement, plant operators must complete upgrades to bottom ash handling systems and wastewater treatment infrastructure to reduce pollutants such as mercury, arsenic and selenium from entering nearby waterways. “This consent decree keeps electricity on the grid and ensures that these power plants reduce their impact on Pennsylvania’s waterways,” said Pennsylvania Department of Environmental Protection (DEP) Secretary Jessica Shirley. “The DEP now has an enforceable schedule for required improvements, as well as enforceable penalties if milestones are missed.”
Across the country, several coal and fossil-fuel plants previously slated for retirement have received temporary extensions because of concerns about grid reliability during extreme weather and periods of rising consumption. In Maryland, Talen Energy delayed the retirement of the Brandon Shores and H.A. Wagner coal and oil-fired plants near Baltimore after PJM warned that shutting them down could threaten grid reliability in the region. The plants are expected to remain available while transmission upgrades are completed. JH Campell in Port Sheldon Michigan followed suit, keeping the plant open nearly a year beyond its planned retirement.
These extensions reflect a broader shift in energy policy nationwide. Utilities and grid operators are increasingly trying to balance emissions reductions with the need for dependable electricity during periods of extreme heat, cold and rapidly growing demand from data centers
For now, Pennsylvania regulators appear focused on maintaining dependable power supplies as summer demand ramps up. With heat waves arriving earlier and electricity consumption expected to continue climbing, officials say keeping Keystone and Conemaugh online through 2032 could provide a critical buffer for the regional grid while the state continues developing future energy resources.
