MISO-S1179 is a proposed 150 MW battery energy storage development project located in Portage County, Wisconsin. The project is listed in the interconnection queue of the Midcontinent Independent System Operator (MISO) and would connect to the transmission system at the Plover point of interconnection. The transmission owner for the interconnection is American Transmission Company. No developer or project name has been publicly identified in the queue data.
The project entered the MISO interconnection queue on July 9, 2026, and its status is active. It has a proposed commercial operation date of September 30, 2028. The queue record lists the service type as SIS, and the project is classified as a standalone storage facility using battery storage technology. The available data does not report the status of an interconnection agreement.
