DULUTH, Minn.–(BUSINESS WIRE)–ALLETE Clean Energy, a wholly owned subsidiary of ALLETE, Inc.

(WPS) as well as Madison Gas and Electric Co. (MGE).

ALLETE Clean Energy acquired the Whitetail wind project in 2021 and developed it for sale to help companies advance their carbon-reduction goals. The approximately 70-megawatt Whitetail project will consist of up to 21 turbines on about 5,938 acres in Clifton and Wingville townships in Grant County. It will produce enough energy to power tens of thousands of homes.

Midwest-based Invenergy will complete development and construction of the Whitetail wind project, as well as provide operations and maintenance services for the life of the project.

In 2023, ALLETE Clean Energy sold the adjacent Red Barn wind project to WPS and MGE.

ALLETE Clean Energy currently owns and operates, in seven states, more than 1,200 megawatts of nameplate capacity wind energy generation that is contracted under PSAs of various durations.
