Granite - Harrisonville 115 kV (queue ID PJM-C01-1916) is a proposed battery energy storage development project in Baltimore City, Maryland. The project is being developed by Great Falls Storage LLC and has a total proposed capacity of 200 MW. It would connect to the transmission system at the Granite - Harrisonville 115 kV point of interconnection, within the service territory of Baltimore Gas and Electric (BGE).
The project is in the interconnection queue of PJM Interconnection, the regional transmission organization serving the area. It entered the queue on April 27, 2026, and has requested Generation Interconnection service. As of the latest available data, the project's status is active, and it is being evaluated in PJM's Cycle 1 (C01) study phase. The developer has proposed a commercial operation date of July 17, 2030.
