ATC to rebuild power lines in Marinette County
Original line built in 1910

DE PERE, Wis. – American Transmission Co., has received approval from the Public Service Commission of Wisconsin to rebuild a 13-mile power line between the Crivitz and High Falls substations in Marinette County. The original line was built in 1910 to deliver energy generated at hydro-electric plants along the Upper Peshtigo River to the city of Green Bay.

“The line needs to be upgraded and its capacity increased to meet reliability needs and provide additional operating flexibility under certain conditions,” explains David Hovde, local relations representative for ATC. Voltage of the double-circuit line will remain 69,000 volts, but larger conductors (wires) will be used to increase the line’s capacity.

Estimated cost of the project is $23.4 million. Construction is expected to begin in summer 2008. Landowners along the right-of-way have been informed of the project and will continue to be kept apprised as the project proceeds.
