The proposed project designated "Surplus; J1132" (queue ID MISO-S1070) is a 40 MW battery storage development project located in Union County, Iowa. It is listed in the Midcontinent Independent System Operator (MISO) interconnection queue, where it holds an active status. The project is classified as a hybrid, with its technology described as a combination of "Other" and battery components. The submitted component data lists a single 40 MW component of the "Other" type. No developer has been identified in the available data.
The project's proposed point of interconnection is ROUNDHOUSEJ1, within the service territory of transmission owner ITC Midwest. Its proposed commercial operation date is August 1, 2025. The "Surplus" designation in the project's name suggests it may have been submitted through MISO's surplus interconnection service process, which allows additional generation or storage to use existing interconnection capacity. This is not confirmed by the data, however. The available data does not specify a queue entry date or the status of an interconnection agreement.
