MISO-J3515 is a proposed energy storage project located in Sangamon County, Illinois, within the Midcontinent Independent System Operator (MISO) region. The project, with a total capacity of 199.9 MW, consists entirely of battery storage technology. The interconnecting utility is City Water Light & Power.
The project entered the MISO interconnection queue on April 17, 2024, with a proposed commercial operation date of May 25, 2026. As of the current data, the project is listed as active in the queue and no interconnection agreement (IA) status is available. The point of interconnection (POI) is listed as 343505 Interstate.
