About

The Wellsville 345 kV project is a proposed 1210 MW natural gas generation project located in Columbiana County, Ohio. The project is being developed within the PJM Interconnection queue under queue ID PJM-AH1-699, which has been moved to TC2. The project entered the queue on April 4, 2025.

This proposed project is currently active in the PJM queue. It is seeking a Generation Interconnection service type with utility ATSI. The Wellsville 345 kV project has been the subject of recent news coverage, with five articles related to industry and development.
