Biggest solar project in Wisconsin goes online at coal-ash landfill

The largest solar project built to date in Wisconsin is generating power, Alliant Energy Corp. said Friday.

The project, installed atop a coal-ash landfill in the Town of Beloit, was built by Hanwha Q Cells for about $5 million.

Alliant will buy electricity from the project for 10 years and has an option to purchase the solar system after that.

Until this week, the state`s largest solar project has been located at Epic Systems` global headquarters in Verona. That project generates 2.2 megawatts of power.
