Badger Coulee Transmission Line Project
American Transmission Co. and Xcel Energy have plans for a high-voltage transmission line in western Wisconsin that would address electric system reliability issues locally and in the Midwest, provide economic savings and support renewable energy policy. The area, from north of La Crosse to northern Dane County, is being considered for the approximately 160- to 180-mile, 345-kilovolt line.
American Transmission Co. and Xcel Energy are jointly developing the Badger Coulee Transmission Line Project. Xcel Energy is a major U.S. electricity and
natural gas company, with retail operations in eight Western and Midwestern states, including Wisconsin. American Transmission Co. is a Wisconsin-based transmission-only utility that owns, operates, builds and maintains transmission facilities in portions of Wisconsin, Michigan, Minnesota and Illinois.
A multi-benefit project
Studies indicate that the Badger Coulee Transmission Line Project is a multi-benefit project that would deliver benefits to Wisconsin and the Midwest region in three important ways:
Improve electric system reliability locally and regionally
- Better enable Wisconsin to import power
- Offset the need for approximately $160 million to $180 million in lower voltage upgrades in western Wisconsin communities
- Alleviate stability issues on regional transmission grid
Deliver economic savings for Wisconsin utilities and electric consumers
- Provide utilities with greater access to the wholesale electricity market with potential savings that can be passed on to electric consumers
- Improve efficiency of grid; more efficient grid reduces the cost to deliver energy
- Connect to high-quality renewable resources in the nation’s western wind alley, which translates into hundreds of millions of dollars in potential savings
Expand infrastructure to support public policy for greater use of renewables
- Establish another pathway for renewable energy into Wisconsin with connections to key load centers
- Match regional studies (Strategic Midwest Area Renewable Transmission Study and MISO Regional Generation Outlet Study) evaluating transmission options that best deliver renewable energy while also addressing reliability issues
ATC and Xcel Energy have a practice of engaging the public and other interested stakeholders in its proposed transmission line projects as a way to identify possible routes far in advance of filing a regulatory application with the Public Service Commission of Wisconsin.
