Pa.’s Largest Coal Plants to Remain Open Through 2032 Under DEP Deal
Pennsylvania’s two largest coal plants will operate four years longer than planned under a new state environmental agreement requiring pollution control upgrades.
HARRISBURG, PENNSYLVANIA — Pennsylvania’s two largest coal-burning power plants will continue operating through 2032 under a proposed agreement with the state Department of Environmental Protection, extending their lifespans by four years beyond their originally scheduled closure dates.
The Keystone and Conemaugh generating stations in Indiana and Armstrong counties were slated to cease operations before the end of 2028 but will remain in service under the new consent decree. Plant owners have agreed to install environmental upgrades to reduce ash and heavy metal pollution from wastewater discharged into western Pennsylvania waterways.
Environmental Upgrades Required by 2028
Under the proposed consent decree, plant operators must complete pollution control upgrades by 2028, with periodic progress deadlines established throughout the implementation period. The Pennsylvania Department of Environmental Protection filed a motion Tuesday in Indiana County Court of Common Pleas seeking judicial approval for the agreement.
The upgrades will specifically target wastewater treatment systems to minimize the discharge of ash and heavy metals into local waterways. The consent decree establishes a framework for monitoring compliance with the environmental improvements.
Energy Supply Concerns Drive Decision
Governor Josh Shapiro defended the agreement as necessary to maintain reliable electricity supply for hundreds of thousands of Pennsylvania homes and businesses. The decision comes as planned data center development is expected to tighten regional energy supplies.
“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,” Shapiro said in a statement.
President Donald Trump also claimed credit for the agreement, characterizing it as a significant victory for Pennsylvania. Trump said his Commerce Department worked with Governor Josh Shapiro to facilitate the deal.
Impact on Regional Power Grid
The extended operations of both coal-fired facilities will help maintain grid stability in western Pennsylvania as energy demand increases. The Keystone Generating Station is located in Plumcreek Township, Armstrong County, while the Conemaugh facility operates in Indiana County.
The agreement balances environmental concerns with energy reliability needs as Pennsylvania faces growing electricity demand from industrial development. The consent decree requires court approval before taking effect, with implementation beginning once judicial authorization is granted.
Environmental groups and energy industry stakeholders are expected to closely monitor the implementation of required pollution control upgrades as the plants continue operations through the end of the current decade.
