Pewaukee-based American Transmission Co. has filed an application with the Public Service Association of Wisconsin to rebuilt 20 miles of transmission line in Rock and Walworth counties.
The rebuild of the aging, 69,000-volt transmission line will cost about $40 million, and would begin in late 2015, with the goal of being operational in 2018.
Wooden poles would be replaced with steel poles and new wires would be installed from the Colley Road Substation in Beloit to the Brick Church Substation in Walworth. The new route would be similar to the old route, with minor adjustments for efficiency, the company said. A new substation would also be built near Clinton.
“The project is needed to replace aging infrastructure, as much of the existing line is more than 60 years old,” said Jon Callaway, senior local relations representative for ATC. “It also will help ensure electric reliability in the area by relieving potential system constraints due to projected load growth.”
