Grant County Solar Project Completed

Alliant Energy has successfully completed constructing its Grant County Solar Project. The 200-megawatt (MW) solar array in Potosi can generate enough electricity to power more than 50,000 homes annually. The project’s completion is the culmination of Alliant Energy’s multi-phase buildout of 12 utility-scale solar projects in Wisconsin totaling 1,089 megawatts. This investment in a more diverse energy generation mix created more than 2,700 jobs across all projects. It improves service reliability and enables Alliant Energy to power nearly 300,000 homes annually with zero-fuel-cost solar energy.

Encompassing over 1,400 acres, the Grant County Solar Project site hosts more than 430,000 solar panels and features nearly 350 acres of native pollinator habitat. Alliant Energy expects the site will generate an estimated $30 million in new shared revenue for the county and town over the life of the project.

In addition to being Wisconsin’s largest owner and operator of solar energy generation, Alliant Energy plans to develop nearly 275 megawatts of energy storage capacity to complement its renewable portfolio. This includes the 100-megawatt Grant County Battery Project that will also be located at the Grant County Solar Project site.

Through the investments outlined in the company’s Clean Energy Blueprint, Alliant Energy is diversifying its generation portfolio, improving energy security and working to achieve net-zero greenhouse gas emissions from utility operations by 2050.
