Alliant Energy proposes wind project to enhance reliability and energy security in Wisconsin

Alliant Energy has filed an application with the Public Service Commission of Wisconsin to construct a 277-megawatt wind farm in Columbia County.

Alliant says If approved, the Columbia Wind project would strengthen reliability for customers and add new capacity to the grid with the proposed plans for more than 40 wind turbines.

Vice president of commercial operations Ben Lipari says “Columbia Wind will have more production capability than any other Wisconsin wind site, while having significantly fewer turbines in operation.

It’s estimated Columbia Wind will generate more than $100 million in tax revenue for Columbia County and will create approximately 100-150 construction jobs.

Once operational, Columbia Wind will produce enough energy to power about 100,000 Wisconsin homes annually.

A decision from the Public Service Commission is expected in early 2027. Pending approval, Alliant Energy plans to place the wind farm into operation by the end of 2028.
