ATC to rebuild transmission line in southeast Wisconsin, four-county region

Original line built in late 1940s

Pewaukee, Wis. – American Transmission Co. has received approval from the Public Service Commission of Wisconsin to reconstruct an existing 53-mile, 138-kV transmission line through a four-county region in southeast Wisconsin. This rebuild will occur between the Waukesha Substation in the City of Waukesha, through Jefferson and Dodge Counties to the St. Lawrence Substation in the Village of Slinger in Washington County.

Known as the Quad County Reliability Project, this project will help maintain reliability of the electric transmission system. The existing transmission line was originally built in the late 1940s and this rebuild will allow the system to meet current and future electricity loads.

Work on the project includes replacing approximately 423 structures along the entire route. New electricity-carrying wires and fiber optic wires will be installed on 35 miles of the line; the remaining portions of the line will carry the existing conductors, which will be transferred from the old structures to the new ones. In some areas, new structures have already been replaced as part of a separate project needed to achieve required safety clearances between the wires and the ground.

Construction is expected to begin in fall 2014. The estimated cost of the project is $59 million and the targeted in-service date is 2017. Landowners along the right-of-way have been informed of the project and will continue to be kept apprised as the project proceeds. No new right-of-way is needed for this project, but ATC will work with landowners to access the right-of-way through their property if necessary.
