The proposed project identified as "Surplus; J1188" (queue ID MISO-S1025) is a 25 MW battery storage development project in Rock County, Wisconsin. It is listed as a hybrid project, with technology categories of "Other" and "Battery." The single reported component is a 25 MW "Other" component, and no separate capacity is given for the battery portion. The project's name indicates it was submitted as a surplus interconnection request associated with queue position J1188. The proposed point of interconnection is the Sheepskin 69kV substation, and American Transmission Company is the transmission owner.
The project is in the interconnection queue of the Midcontinent Independent System Operator (MISO), where it holds active status. It entered the queue on May 16, 2022, with a proposed commercial operation date of June 1, 2022, only about two weeks after the queue entry date. The available data does not report the status of an interconnection agreement, and the project is not linked to an existing operating plant in EIA records.
