The company will also build a new substation as part of the project to improve electric system reliability.
Work on the 17-mile line will involve replacing poles and wires on the existing 69kV transmission line, adding a 161kV circuit to the new steel poles and building the new Timberwolf substation approximately one half-mile south of Interstate 90 along Highway 131.
ATC is coordinating with Dairyland Power Cooperative, Xcel Energy, Alliant and Oakdale Electric Cooperative on the project. Construction of the approximately $36m project will be completed within the area of the existing right-of-way and is expected to be in service mid-2013.
ATC owns, operates, builds and maintains a high-voltage electric transmission system serving portions of Wisconsin, Michigan, Minnesota and Illinois.
