The La Crosse-Madison Transmission Line Complete
The La Crosse-Madison Transmission Line Project, also known as the Badger Coulee Project, was completed and energized in December 2018. The approximately 180-mile, 345 kilovolt (kV) line runs between the Briggs Road Substation north of La Crosse and the Cardinal Substation in northern Dane County.
The line provides electric system reliability to benefit Western Wisconsin communities, the state of Wisconsin and the entire Midwest region and provide access to lower-cost power and renewable energy.
Xcel Energy and American Transmission Company (ATC) filed an application for the project with the PSCW in October 2013. The application was approved in April, 2015.
PSC Docket ID: 137-CE-160: Go to the Public Service Commission of Wisconsin (PSC) website to learn more about the transmission filings.
Project construction began in 2016, starting at the southern end of the project in Dane County, WI and continued to Briggs Road Substation in La Crosse County. American Transmission Co. and Xcel Energy jointly developed the Badger Coulee Transmission Line Project.
