Mitchell - Wilson 138 kV & Clairton - Piney 138 kV (queue ID PJM-C01-2149) is a proposed battery energy storage project located in Allegheny County, Pennsylvania. The development project is being advanced by Gemini Elrama, LLC and has a total proposed capacity of 800 MW. The project is named for its point of interconnection, which comprises the Mitchell - Wilson 138 kV and Clairton - Piney 138 kV transmission lines within the service territory of Duquesne Light (DL).
The project is listed with an active status in the interconnection queue administered by PJM Interconnection, the regional transmission organization. It entered the queue on April 27, 2026, under the Generation Interconnection service type, and is being evaluated as part of PJM's Cycle 1 (C01) study phase. The proposed commercial operation date is April 2, 2029. The available data does not indicate that an interconnection agreement has been executed.
