ATC files application for Quad County Electric Reliability Project

Project involves rebuilding aging line in southeastern Wisconsin

PEWAUKEE, Wis. – American Transmission Co. is seeking approval from state regulators for a project to improve electric system reliability by rebuilding 58 miles of existing 138-kilovolt transmission lines in portions of four southeastern Wisconsin counties: Waukesha, Jefferson, Dodge and Washington.

ATC this week filed the required regulatory application for a Certificate of Authority with the Public Service Commission of Wisconsin. Permits also are needed from the Wisconsin Department of Natural Resources.

The reconstruction is needed to replace aging equipment that is approaching the end of its lifespan. The rebuilt line will help meet current and future electricity loads, and support the safe and reliable operation of the electric system. 

Work on the project includes replacing the majority of the structures along the entire 58 mile route. No new right-of-way is needed. New conductors and fiber optic wires will be installed on 35 miles of the line; new structures on the remaining 23 miles will carry existing conductors, which will be transferred from the old structures to the new ones.

ATC anticipates regulatory approval in spring 2013 and the start of construction in fall 2014. The estimated cost of the project is $64 million and the targeted in-service date is spring 2017.
