ATC plans to rebuild line in Boscobel, Lone Rock area

Project will improve aging infrastructure, enhance local electric reliability

MADISON, WIS. – American Transmission Co. has filed an application with 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 the 27.6-mile segment 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.

“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.”

If the estimated $32 million project is approved, construction would start in June 2017 with an anticipated in-service date of December 2019.

Additional details are available on the PSC website under Docket No. 137-CE-181.
