Background
In March 2025, LS Power announced it had applied to construct approximately 700 MW of new generation as part of PJM's Reliability Resource Initiative (RRI), which is designed to expedite connecting shovel-ready, high-reliability projects to the grid. LS Power's proposals include converting two peaking facilities, the Armstrong Gas power station in Pennsylvania and the Troy Energy power station in Ohio, to base-load combined cycle plants, along with uprates at other existing facilities in Pennsylvania and Virginia. The two conversion projects would add approximately 600 MW through the addition of a steam cycle at each facility.[4]
