State regulators have approved an expansion of solar power plants by Alliant Energy.
The Public Service Commission approved a 414-megawatt expansion of Alliant Energy’s solar plants on Thursday. This is in addition to a 675-megawatt expansion that was approved in 2021.
The new plants will be in Dane, Grant, Green, Rock, and Waushara Counties. Alliant wants to have 20 percent of its electricity solar based by 2025.
