Status
Active
Active in the MISO queue. This is a request to keep 303.5 MW of Edgewater Unit 5 coal capacity in place of the BESS originally planned there. Alliant has said it will delay Unit 5's coal retirement and convert it to gas by 2028.

About

MISO-R1049, listed in the queue as "Replacing 303.5 MW BESS with 303.5 MW COAL; Edgewater Unit 5," is a proposed development project in Sheboygan County, Wisconsin, within the Midcontinent Independent System Operator (MISO) region. The queue record classifies it as a hybrid project totaling 303.5 MW, with technology listed as coal and "Other." Its single reported component is 303.5 MW categorized as "Other." The project name indicates it would replace a previously proposed 303.5 MW battery energy storage system (BESS) with 303.5 MW of coal capacity associated with Edgewater Unit 5. No developer is identified in the available data.

The project entered the MISO interconnection queue on December 24, 2024, and its status is active. It has requested Network Resource Interconnection Service (NRIS) and would connect at the Edgewater 345 kV point of interconnection, with American Transmission Company as the transmission owner. The proposed commercial operation date is June 1, 2025. The available data does not report the status of an interconnection agreement.
