Project information


We’re developing a wind energy project in southwest Marathon County. The Hub City Wind Farm extends our historic presence in Wisconsin and unites a coalition of partners committed to building a strong, resilient energy future. Wind energy allows us to deliver safe, reliable, affordable energy to customers as part of a balanced mix of new and traditional generation sources.

This project will create new construction jobs and ongoing positions in operations and maintenance once in service. We expect it to generate enough renewable, low-cost energy to power nearly 30,000 homes annually.

Proposed timeline (subject to change)

  • 2027 - Submit permit application to the Wisconsin Public Service Commission (PSC).
  • 2029 - If approved, construction begins.
  • 2031 - Project operational.
