MISO-J1629 is a proposed 200 MW solar generation project located in Columbia County, Wisconsin. The development project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO), with American Transmission Company identified as the interconnecting transmission utility. The project's proposed point of interconnection is the Columbia SW YD (ALTE) to South Fond Du Lac SW YD 345 kV transmission line. It has requested Network Resource Interconnection Service (NRIS). No developer is identified in the available data.
The project entered the MISO queue on June 22, 2020, and was studied as part of the DPP-2020 East (ATC) study cycle. Its queue status is active. An interconnection agreement (IA) was executed on October 1, 2024. The project's proposed commercial operation date was July 18, 2024, which predates the execution of its interconnection agreement.
