Twin Branch - Argenta 345 kV (queue ID PJM-C01-1409) is a proposed 200 MW battery energy storage development project located in Cass County, Michigan. The project is being developed by Bair Lake Power, LLC and would connect to the transmission system at the Twin Branch - Argenta 345 kV point of interconnection, within the service territory of the utility AEP. It is a standalone storage project and does not include a co-located generation component.
The project is listed in the PJM Interconnection queue with an active status. It entered the queue on April 27, 2026, under the Generation Interconnection service type. It is being evaluated as part of PJM's C01 study phase, which is the first cycle under the regional transmission organization's reformed interconnection process. The project's proposed commercial operation date is December 31, 2030. The available data does not indicate the status of an interconnection agreement.
