MISO-J1677 is a proposed 180 MW solar generation project located in Macon County, Illinois. The development project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO), with Ameren Illinois as the associated transmission utility. The project would connect to the grid at the Leghorn 345 kV point of interconnection and has requested Network Resource Interconnection Service (NRIS). No developer name is identified in the queue data.
The project entered the MISO queue on June 24, 2020, and is being studied in the DPP-2020 Central study phase. Its queue status is active. The proposed commercial operation date of April 20, 2023 has already passed, and the project has not yet reached operation. Its interconnection agreement is listed as "IA Pending," with an associated IA date of June 20, 2025.
