The Surplus; J1000 development project is a proposed 25 MW hybrid energy project located in Grant County, Wisconsin. The project, consisting of a 25 MW battery component and an additional 25 MW component of unspecified "Other" technology, is in the Midcontinent Independent System Operator (MISO) interconnection queue as project S1023. The queue entry date is May 16, 2022, with a proposed commercial operation date of March 27, 2023.
The project is interconnected to the American Transmission Company via the Nelson Dewey - Lancaster 138kV point of interconnection. The project is currently listed as active in the MISO queue. Recent news coverage has discussed the project.
