MISO-J1377 is a proposed solar generation project located in Rock County, Wisconsin, with a total capacity of 98.56 MW. The project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO), within the service territory of American Transmission Co. No developer has been publicly identified in the queue data. The project would connect to the grid at the Wempletown–Rockdale 345 kV line tap and has requested Network Resource Interconnection Service (NRIS).
The project entered the MISO queue on April 29, 2019, and was studied as part of the DPP-2019 East (ATC) study cycle. Its proposed commercial operation date was July 15, 2022, a date that has since passed. The project remains active in the queue, and its interconnection agreement was executed on November 18, 2025.
