The proposed project identified in the Midcontinent Independent System Operator (MISO) interconnection queue as MISO-R1038, described as "replacing 100MW of un-built solar with BESS; Mayhew," is a battery energy storage development project in Benton County, Minnesota. The project totals 100 MW and is classified as a hybrid project type, with technology entries of "Other" and "Battery." Its one listed component is a 100 MW "Other" component. As the queue description indicates, the proposal would substitute battery energy storage system (BESS) capacity for 100 MW of previously planned solar generation that has not been built. The associated utility is Northern States Power Company.
The project entered the MISO queue on November 28, 2023, and its status is active. It has requested Network Resource Interconnection Service (NRIS) and would connect at the Mayhew Lake 115 kV point of interconnection. The proposed commercial operation date is November 1, 2025. The available data does not indicate the status of an interconnection agreement.
