ATC project will improve electric reliability for Brodhead, Monroe areas

Construction of the rebuilt line will begin in May

MADISON, Wis. – American Transmission Co. in May will begin construction on the 18-mile, 69,000-volt Brodhead-South Monroe electric transmission line that connects the Brodhead Substation south of Brodhead and the South Monroe Substation in Monroe. The Public Service Commission of Wisconsin approved the project in April 2009.

Construction activities on the approximately $11 million project are expected to being in May 2011, and the line is projected to be in service in December 2011. The age and condition of the existing line, which was built in 1950, necessitated the rebuild. “Work will involve installing new poles, wires, and insulators,” said Jim Maple, ATC project manager. “The rebuild line will follow the existing route and the new line design will allow for longer span lengths and fewer poles.”

“The rebuilt line will make a vital improvement to electric system reliability in the area,” said Charles Gonzales, ATC local relations representative. “We will continue to communicate with affected landowners throughout the construction process.”
