Wisconsin regulators have signed off on the second phase of Alliant Energy’s $1.5 billion solar energy plan.

The Wisconsin State Journal reports the Public Service Commission on Thursday unanimously approved Alliant’s plan to buy or build six solar farms in Dane, Grant, Green, Rock and Waushara counties for $620 million.

Together the plants are expected to produce 441 megawatts of electricity, enough to power about 100,000 homes.

Alliant is working to replace its coal-fired power plants in the next two years.
