Halfway - Marlowe 138 kV (queue ID PJM-C01-2103) is a proposed 40 MW battery energy storage development project in Washington County, Maryland. American Power Ventures, LLC is developing the project, which would connect to the transmission system of APS (the local utility) at the Halfway - Marlowe 138 kV point of interconnection. The project is classified as a standalone storage facility and has requested generation interconnection service.
The project is listed as active in the PJM Interconnection queue, which it entered on April 27, 2026. It is being evaluated in PJM's C01 study phase. The developer has proposed a commercial operation date of August 3, 2026. The available queue data does not report the status of an interconnection agreement.
