MISO-S1017, listed in the queue under the name "Surplus; J947," is a proposed battery storage development project in the Midcontinent Independent System Operator (MISO) region. The project is classified as a hybrid, with technology details listing both "Other" and battery components. Its total capacity is 100 MW, all of which is recorded under a single component designated "Other." The project would interconnect at the Tennyson 138kV point of interconnection, within the transmission system of American Transmission Company. The data does not identify the county, state, or developer.
The proposed project entered the MISO interconnection queue on April 11, 2022, and currently holds an active status. Its proposed commercial operation date was June 1, 2023. The "Surplus" designation in its name suggests a surplus interconnection service request, a mechanism that allows additional generation or storage to use unused capacity at an existing interconnection point. The available data does not specify the status of an interconnection agreement for the project.
