American Transmission Company (ATC) on Oct. 9 said that the portion of the Badger Coulee Transmission Line Project connecting the Cardinal substation in the Town of Middleton to the North Madison substation in the Town of Vienna has been energized.
While that 20-mile segment is complete and moving electricity, the portion of the project between the North Madison substation and the Briggs Road substation in the La Crosse area is still under construction, the company said.
The 180-mile, 345-kV Badger Coulee line was approved by the Public Service Commission of Wisconsin in April 2015, and is expected to be in service by late 2018, ATC said.
According to the project’s webpage, ATC and Xcel Energy (NYSE:XEL) jointly developed the project, which is designed to, for instance, better enable Wisconsin to import power; offset the need for about $160m to $180m in lower voltage upgrades in western Wisconsin communities; alleviate stability issues on the regional transmission grid; and establish another pathway for renewable energy into Wisconsin with connections to key load centers.
The project is estimated to cost about $580m, according to the webpage.
