Calumet 138 kV (PJM queue ID PJM-C01-2138) is a proposed battery energy storage development project in Cook County, Illinois. The project is being developed by Sun Dispatch II LLC and would have a total capacity of 365 MW. It is planned to connect to the grid at the Calumet 138 kV point of interconnection, within the service territory of the utility ComEd.
The project is listed as active in the PJM Interconnection queue, which it entered on April 24, 2026. It is being studied in the C01 study phase and has requested Generation Interconnection service. Its proposed commercial operation date is June 30, 2030.
