Elwood 345 kV is a proposed battery energy storage development project located in Will County, Illinois. The project is being developed by Elwood Energy LLC and has a total proposed capacity of 300 megawatts (MW). It is designed to connect to the electric grid at the Elwood 345 kV point of interconnection, within the service territory of the utility Commonwealth Edison (ComEd).
The project is listed in the interconnection queue of PJM Interconnection, the regional transmission organization serving the area, under queue ID PJM-C01-1311. It entered the queue on April 25, 2026, and has requested Generation Interconnection service. As of the most recent data, the project holds an active status and is in the C01 study phase of PJM's interconnection process. Its proposed commercial operation date is December 31, 2029.
