MISO-J1779 is a proposed solar-plus-battery hybrid development project located in Dane County, Wisconsin. The project has a total capacity of 200 MW, all of which is attributed to its solar component in the interconnection data. The battery storage component is listed as part of the project's technology, but no separate capacity is specified for it. The project is proposed to connect at the Rockdale point of interconnection, within the transmission system of the American Transmission Company (ATC). It has requested Network Resource Interconnection Service (NRIS).
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on September 1, 2021, and currently holds active status. It was studied as part of the DPP-2020 East (ATC) study phase. An interconnection agreement was executed on October 9, 2024. The project's proposed commercial operation date was October 31, 2024.
