Alliant Energy customers are now receiving clean power from Wisconsin's largest solar facility. The 2.3MW Rock River solar project recently went into service near Beloit, Wis. The sun-powered generating station includes over 7,700 solar panels, covers nearly 17 acres and produces enough electricity to power 500 homes.

"Investments in clean energy have been central to our plan for decades," said Patricia Kampling, Alliant Energy Chairman, President and CEO. "Solar is an important part of our future energy mix, and one of many ways we are following a path of sustainability and stewardship."

The Rock River solar project is located on Alliant Energy's property in the Town of Beloit, and it is sited on a landfill, a further environmental benefit. The company collaborated with the Wisconsin Department of Natural Resources to enable the landfill site to be reused for the solar facility.

Alliant Energy signed a 10-year power purchase agreement with Hanwha Q CELLS USA, which owns and operates the project that includes an option to purchase the facility at the end of the contract.
