The Suffolk 230 kV project is a proposed battery energy storage development project located in Suffolk, Virginia. Developed by Switchgrass Solar I, LLC, the project has a total proposed capacity of 51 MW and is classified as a standalone storage project. It would connect to the transmission system at the Suffolk 230 kV point of interconnection, within the service territory of Dominion.
The project is listed in the PJM Interconnection queue under queue ID PJM-C01-1686 and holds an active status. It entered the queue on April 25, 2026, as a Generation Interconnection request, and is currently in study phase C01. The proposed commercial operation date is December 31, 2031.
