One of the largest solar projects in Wisconsin is located on 58 acres at the Dane County Regional Airport. More than 20,000 solar panels generate 9 megawatts of renewable electricity— enough to meet 40% of the electricity used by all county-owned facilities. Madison Gas and Electric (MGE) owns the solar system, which is installed on land rented from the County. The solar farm also doubles as a habitat for monarch butterflies and other pollinator populations.
The project was completed in December 2020.
