MISO-J1839 is a proposed 340.3 MW natural gas-fired generation project located in Macon County, Illinois. The development project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO). It would connect to the transmission system at the Decatur ADM North 138 kV point of interconnection, within the service territory of Ameren Illinois. No developer or project name has been publicly identified in the queue data.
The project entered the MISO queue on June 25, 2020, and is being evaluated in the DPP-2020 Central study phase. It has requested Network Resource Interconnection Service (NRIS). As of the most recent data, the project holds an active status, with its interconnection agreement listed as pending and an associated IA date of June 16, 2025. The proposed commercial operation date is January 1, 2027.
