MISO-S1143 is a proposed 135 MW generation project in Illinois, listed in the interconnection queue of the Midcontinent Independent System Operator (MISO). The project's technology is classified as "Other" in queue records, and no developer or county-level location has been disclosed. The project is planned to connect to the transmission system of Ameren Illinois, the interconnecting utility.
The project entered the MISO queue on January 20, 2026, and remains in active status. Its proposed commercial operation date is December 31, 2027. The queue entry lists a service type of SIS. No interconnection agreement status is reported in the available data.
