MISO-J1508 is a proposed 98.9 MW wind generation project located in Marathon County, Wisconsin. The development project would consist entirely of wind generation capacity and is planned to interconnect to the transmission system owned by American Transmission Company (ATC). Its point of interconnection is identified as the B-54 Wien to McMillan 115 kV line. No developer or project name has been disclosed in the available queue data.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on June 19, 2020, and is listed with an active status. It was studied as part of the DPP-2020 East (ATC) study cycle and has requested Network Resource Interconnection Service (NRIS). The project's proposed commercial operation date was September 1, 2023, a date that preceded the execution of its interconnection agreement. An interconnection agreement was executed on September 23, 2024, marking an advanced stage in the MISO interconnection process.
