The Couderay to Osprey line is a $50 million, 35.5 mile high voltage system will provide greater reliability along a corridor that runs from Eau Claire, Wisconsin to Ironwood, Michigan. The 161/69 kV double-circuit line will support load growth.
The project included rebuilding an aging transmission line that connects the Couderay Substation in Sawyer County with the Osprey Substation in Rusk County.
“The existing line was more than 60 years old and needed to be upgraded,” said Kelsey Holthaus, project manager, in a statement. “The new infrastructure creates additional capacity on the transmission grid to meet the growing needs of industry and businesses in northern Wisconsin.”
The Public Service Commission of Wisconsin approved the Certificate of Authority for this project on October 25, 2012. 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.
