Cassville Solar Project gets green light to begin construction

Customers and communities around Cassville will benefit from new jobs, increased local revenue and clean energy generation.

MADISON, Wis. (June 14, 2022) – Construction is poised to move forward on the Cassville Solar Project after state regulators gave final approval to Alliant Energy’s second phase of solar development plans. The 50-megawatt (MW) solar project in the Grant County town of Cassville will generate enough electricity to power nearly 13,000 Wisconsin homes. Alliant Energy expects construction to create more than 100 jobs.

“At Alliant Energy, we’re driven by our commitment to serve customers and build stronger communities,” said David de Leon, president of Alliant Energy's Wisconsin energy company. “We are excited to break ground and begin construction on the Cassville solar project, a key component of our plans to accelerate toward a cleaner energy future. We expect our solar development plans to create hundreds of new construction jobs and deliver safe, reliable, affordable energy for years to come.”

The company expects to begin construction this summer and finish in late 2023. Alliant Energy will contract with Burns & McDonnell and utilize craft labor from several local union halls.

“We appreciate Alliant Energy’s prioritization of local unionized labor on renewable energy projects,” said Emily Pritzkow, executive director of the Wisconsin Building Trades Council. “Alliant Energy understands the benefits of hiring local labor, the development of a strong workforce through apprenticeships and training, and the ripple effect it has on our local economies, and state as a whole. When businesses partner with the skilled forces of Wisconsin’s unionized building trades, they know they’re going to get a safe, quality product that delivers superior value for everyone.” 

The Cassville Solar Project is among 12 utility-scale solar sites Alliant Energy is developing as part of its Clean Energy Blueprint that will add nearly 1,100 MW of solar energy generation to Wisconsin’s energy grid and help customers avoid more than $1.6 billion in long-term costs. In addition to powering homes and businesses, the Cassville solar project will generate an estimated $200,000 in annual shared revenues for the community and county over the next 30 years.
