The Surplus; J1304 development project is a proposed 33 MW hybrid project consisting of a 33 MW battery energy storage system. It is located in Rock County, Wisconsin, and interconnects within the Midcontinent Independent System Operator (MISO) region. The project, which appeared in recent news coverage, entered the MISO interconnection queue as queue ID MISO-S1035 on August 15, 2022, with a proposed commercial operation date of July 1, 2023.
The project is currently listed as active in the interconnection queue and will connect to the American Transmission Company grid at the Townline Rd. - Paddock 138kV point of interconnection.
