The Badger Coulee high-voltage transmission line will be built, and it will follow a route from a substation near Holmen, north of La Crosse, to the Madison area, the Wisconsin Public Service Commission (PSC) decided in a unanimous preliminary vote Thursday.
The 345-kilovolt line will keep the electricity supply reliable and sufficient, and will bring economic benefits to the region, agreed the three-member panel, all appointees of Gov. Scott Walker.
The 180-mile project, proposed by Pewaukee-based American Transmission Co. (ATC) and Xcel Energy, will cost an estimated $580 million. Construction is expected to begin in 2016 and the line is scheduled to go into service in 2018.
