Pa. study targets retired power plants for reactivation
Pennsylvania aims to reactivate 21 retired power sites to boost grid reliability.
In brief
Pennsylvania aims to reactivate 21 retired power sites to boost grid reliability. Pennsylvania's PATER study identifies 21 sites for new power generation to address grid strain from data centers and industrial demand. Originally reported by PhillyVoice.
Pennsylvania study begins
A $2 million U.S. Department of Energy grant funds a study to identify retired power plant sites for reactivation in Pennsylvania.
Study aims to narrow sites
The program will narrow 76 decommissioned sites to 21 locations with potential for quick new power generation deployment.
Grid reliability focus

The study targets sites to address unprecedented electricity demand from data centers and industrial users.
Economic development goal
Team Pennsylvania says the study will revitalize communities with industrial legacies to create long-term economic growth.
PUC involvement
The Pennsylvania Public Utility Commission (PUC) partners with KeyLogic Systems and Team Pennsylvania on the study.
Study timeline
The PUC held a three-hour hearing on October 5, with public meetings scheduled through March 2027.
Grid capacity analysis
The study found transmission capacity at 9 gigawatts statewide, indicating the grid can support new generation and load development.
Site characteristics
Most sites are within a mile of transmission lines and substations, with half less than 1.5 miles from natural gas pipelines.
Site size variations
Average decommissioned coal sites are 200 acres, while natural gas and oil sites average less than 100 acres.
Potential risks
The study identifies groundwater contamination, flooding and geological issues as potential risks at redevelopment sites.
Investment opportunities
Constellation Energy and Google announced a $4.3 billion commitment to upgrade nuclear power plants in Pennsylvania.
PJM grid updates
PJM has cleared a backlog of projects and reformed its review process to prioritize proposals with significant financial commitments.
Grid reliability concerns
A September PUC report warns of rolling blackouts even with new power generation over the next 15 years.
Next steps
The study will provide guidance for investors on where new power plants can be added to the grid to power homes and businesses.
The short version
Pennsylvania's PATER study identifies 21 sites for new power generation to address grid strain from data centers and industrial demand.
