Alliant Energy announced it has completed six new solar projects in Wisconsin, tripling the company's solar generation capacity and adding a total of 514 MW of solar energy to the state’s energy mix.

“Completing these projects is a huge milestone and a pivotal moment in our journey toward a brighter energy future,” said David de Leon, Alliant Energy Wisconsin President. “We’re proud to leverage new technology and locally generated energy solutions to increase customer value and help avoid long-term cost.”

Alliant Energy’s six newly completed projects include:

  • Albany Solar – 50 MW in Green County
  • Cassville Solar – 50 MW in Grant County
  • Onion River Solar – 150 MW in Sheboygan County
  • Paddock Solar – 65 MW in Rock County
  • Springfield Solar – 100 MW in Dodge County
  • Wautoma Solar – 99 MW in Waushara County

Each site utilizes only sunlight for fuel, allowing the solar arrays to automatically track the movement of the sun to maximize energy generation. The durable, high-performance bi-facial solar panels not only improve site efficiency but are capable of withstanding severe weather conditions, including high winds, snow, and hail.

Alliant Energy also included native low-growth grass and approximately 300 acres of native pollinator habitat across each of the six sites to enhance the environmental benefits of the arrays. These features will allow the company to ensure a more stable energy future and provide long-term economic and financial benefits to the local communities.

Construction on these sites began in 2022 and employed nearly 1,000 workers during that time.

These six newly completed projects are part of Alliant Energy’s 12 utility-scale solar projects portfolio created as part of its Clean Energy Blueprint to deliver greater energy reliability and achieve net-zero greenhouse gas emissions from utility operations by 2050.

Once all projects are completed by mid-2024, they will be capable of generating 1,089 MW and powering nearly 300,000 homes annually.
