McDowell 138 kV (queue ID PJM-C01-2166) is a proposed 400 MW battery energy storage development project in Mercer County, Pennsylvania. The developer is REPA Wayside Church Solar, LLC. The project would connect to the grid at the McDowell 138 kV point of interconnection, within the transmission territory of ATSI (American Transmission Systems, Inc.).
The project is listed as active in the PJM Interconnection queue. It entered the queue on April 27, 2026, and requested Generation Interconnection service. It is being evaluated in PJM's Cycle 1 (C01) study phase, and its proposed commercial operation date is December 31, 2031.
