TSS 903 Tovey 345 kV is a proposed 18 MW battery energy storage project in Christian County, Illinois. The development project is being pursued by Black Diamond Solar Power, LLC and would connect to the transmission system at the TSS 903 Tovey 345 kV point of interconnection, within the service territory of the utility ComEd. The project is classified as a standalone storage facility and has been submitted under the Generation Interconnection service type.
The project is listed in the PJM Interconnection queue under queue ID PJM-C01-2155, with a queue entry date of April 27, 2026. It is currently active and is being evaluated in the C01 study phase of PJM's interconnection process. The proposed commercial operation date is October 15, 2030. The available data does not indicate the status of an interconnection agreement.
