MISO-J955 is a proposed 1,165 MW natural gas-fired generation project located in Sangamon County, Illinois. The development project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO), with Ameren Transmission Company of Illinois as the interconnecting transmission owner. The project would connect to the grid at the Austin Substation 345 kV bus and has requested Network Resource Interconnection Service (NRIS). No developer name or project name is identified in the available queue data.
The project entered the MISO queue on March 8, 2018, and was studied as part of the DPP-2018-APR Central cycle of MISO's Definitive Planning Phase. Its proposed commercial operation date was November 1, 2021, a date that has since passed. An interconnection agreement was executed on April 26, 2022, and the project's IA status is now listed as "Construction." The queue entry remains active.
