ATC seeks approval to rebuild 14-mile, 138-kV transmission line

Posted on April 9th, 2015 4/9/15

Project needed to replace aging lines, strengthen area reliability

PEWAUKEE, Wis. – American Transmission Co. today filed an application with the Public Service Commission of Wisconsin to rebuild an existing 14-mile, 138,000-volt transmission line in southeastern Wisconsin. The proposed St. Martins-Edgewood-Mukwonago Rebuild Project runs from the St. Martins Substation in Franklin to the Edgewood Substation in Big Bend and continues on to the Mukwonago Substation, in Mukwonago.

“The lattice tower structures, which are approximately 90 years old, will be replaced with steel single-pole structures; and the wires also will be replaced,” said Mary Carpenter, senior local relations representative for ATC. “The new poles will be placed within a few feet of the existing structures, and no new right-of-way is anticipated for the project.”

Regulatory approval of this project is expected in fall 2015 with construction beginning in 2017 to meet an in-service date of 2018.

Note to editors: Additional details are available on the PSC’s website under Docket No. 137-CE-180. A map of the proposed project and additional information can found at www.atc-projects.com.
