Xcel Energy (NYSE:XEL) said Dec. 6 that it has completed work on the $50m Couderay to Osprey electric transmission line in Wisconsin.
The upgraded 35.5-mile span should enhance reliability in northern Wisconsin, Xcel Energy said in a news release.
Couderay to Osprey is a 161-kV-69-kV upgrade project, according to an Xcel Energy website. Construction on the project began in 2014. It was placed into service in late November.
The project included rebuilding an aging transmission line that connects the Couderay Substation in Sawyer County with the Osprey Substation in Rusk County. The project consists of replacing the existing two-pole wood structures with single-pole steel structures.
The Public Service Commission of Wisconsin approved the Certificate of Authority for this project in October 2012. The project was developed by Xcel Energy affiliate Northern States Power-Wisconsin.
The two-year construction process also replaced two-pole wood structures with single-pole steel structures and existing substations were modified or expanded to accommodate the higher voltage.
“The existing [69-kV] line was more than 60 years old and needed to be upgraded,” said Kelsey Holthaus, project manager. “The new infrastructure creates additional capacity on the transmission grid to meet the growing needs of industry and businesses in northern Wisconsin and provides more electric reliability along a corridor that runs from Eau Claire, Wisconsin, to Ironwood, Michigan.”
