PSC approves project to rebuild transmission line in Boscobel, Lone Rock areas
Work will improve aging infrastructure, enhance local electric reliability
MADISON, WIS. – American Transmission Co. today received approval from the Public Service Commission of Wisconsin to rebuild and reroute portions of an approximately 28-mile, 69,000-volt transmission line from Boscobel to Lone Rock, Wisconsin.
The project will involve:
- Rebuilding approximately 25 miles of a 27.6-mile line between the Boscobel and Lone Rock substations,
- Replacing poles and communications fiber in select areas of the remaining 2.6 miles of line; and
- Rerouting two segments of the line (approximately 9 miles) due to existing access and maintenance concerns and environmental sensitivities.
Existing wood structures will be replaced with weathering steel structures. The line will consist of primarily single-pole structures ranging in height from 60 to 95 feet. A small portion of the line near the Wisconsin River will include H-frame structures.
“The current line was built in the 1950s and is in poor condition,” said Jon Callaway, ATC senior local relations representative. “Rebuilding the line and replacing poles will help ensure electric reliability in the area. Additionally, rerouting two segments of the line will improve access for maintenance and reduce environmental impacts.”
Construction of the approximately $32 million project is expected to start in summer 2017 with an anticipated in-service date of December 2019.
Additional project details are available on the PSC website under Docket No. 137-CE-181.
