About the project

The Paddock Solar Project is an estimated 65-megawatt (MW) solar project located in Rock County, Wisconsin. The Paddock Solar Project will connect into the electrical transmission grid directly through the local substation. Once complete, the project will positively impact the environment and generate enough clean, low-cost energy to power thousands of homes.

"RENEW Wisconsin wholeheartedly supports Public Service Commission approval of the Alliant Energy’s application to acquire, construct, own, and operate the Paddock Solar Project. Not only would Alliant Energy’s proposed power plants generate electricity from a noncombustible renewable resource, consistent with Wisconsin’s Energy Priorities Law, these solar projects would do so at the scale needed to achieve deep carbon reductions."

Project updates

August 2, 2023

Our Paddock Solar Project continues to move toward completion as we're more than 50% complete installing the solar panels. Our latest newsletter also includes information on International Workers' Day and agrivoltaics, the study of agriculture and solar production co-existing. We expect to complete the Paddock Solar Project by the end of this year!

Economic benefits

  • The Paddock Solar Project will be a significant source of new local tax revenue, providing approximately $260,000 in annual shared revenue for the Town of Beloit and Rock County.
  • During construction, between 100 and 200 local union jobs will be created. This Midwest Economic Policy Study describes the benefits of using local union labor at little to no additional cost to customers.
  • Once operational, a few full-time employees will help ensure the project is running smoothly.
  • Alliant Energy will provide lease payments to landowners in the project area for the 30-year lifespan of the project.
  • In addition, soil recovery during the project’s lifespan will protect agricultural land and preserve its value for future generations.

Environmental benefits

  • This project will feature grass and seed mixes surrounding the solar panels and throughout the solar arrays that will help build soil nutrients and create a pollinator-friendly habitat. Pollinator-friendly vegetation has been proven to prevent soil erosion and add benefit to high-value crops, creating a win-win for both human and wildlife communities.
  • Once the grass matures in four years following construction, the water quality of surrounding waterbodies is expected to improve because of reduced nitrogen, phosphorus, sediment, and biological oxygen demand entering these waterbodies. This improves the ecological health of the watershed and the quality of life for all inhabitants, as high loadings of these pollutants can produce excess algae growth and degrade the habitat in adjacent waterbodies.
  • Requiring only sunlight for fuel, the Paddock Solar Project represents a long-term reduction of traditional fossil fuels for energy generation, creating a clean environment and clean energy future for Wisconsin and the Midwest.

Solar and the Clean Energy Blueprint

The Paddock Solar Project is one of the 12 solar projects Alliant Energy has received approval to own and operate in Wisconsin. The projects span dozens of communities across nine counties. Collectively, these projects will add nearly 1,100 MW of solar energy generation to the state’s energy grid by the end of 2023 – enough to power nearly 300,000 homes.

These projects demonstrate our commitment to advancing clean energy and strengthening the communities we serve. They create an economic boost for communities and landowners while providing customers with reliable, environmentally friendly energy for decades to come.

Collectively, our solar projects, along with the rest of our Clean Energy Blueprint, are also a smart investment that will help customers avoid more than $1.6 billion in long-term costs. They will also provide steady revenue through new construction opportunities, create an estimated 2,000 construction jobs and provide approximately $300 million in revenues to local communities and landowners over an estimated project lifespan of 30 years.

As we move toward creating a healthier environment, these initiatives are positioning Alliant Energy to achieve net-zero carbon dioxide emissions from the electricity we generate by 2050.
