The Carson - Suffolk 500 kV (AE1-173 switching station) project is a proposed 400 MW battery energy storage development project located in Sussex County, Virginia. The project is being developed by Clenera DevCo, LLC and would connect to the transmission system of Dominion, the local utility. Its point of interconnection is identified as the Carson - Suffolk 500 kV line at the AE1-173 switching station, the same designation used as the project's name.
The project is listed in the PJM Interconnection queue under queue ID PJM-C01-1496 and holds an active status. It entered the queue on April 25, 2026, and has requested Generation Interconnection service. The project is being studied in PJM's C01 study phase. Its proposed commercial operation date is December 1, 2030.
