MISO-S1181 is a proposed battery energy storage development project located in Story County, Iowa. The project would have a total capacity of 150 MW and is classified as a standalone storage project. No developer has been identified in the available queue data. The project's point of interconnection is listed as Story County, within the service territory of transmission owner ITC Midwest.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on March 2, 2026, and its status is active. It is being evaluated under the SIS service type, and its proposed commercial operation date is June 1, 2028. The available data does not indicate an executed interconnection agreement, and the project is not linked to any existing operating plant in EIA records.
