Dairyland Power Cooperative’s 161-kV Genoa to La Crosse transmission project in Wisconsin was energized in June, a cooperative spokesperson told TransmissionHub.
Construction began in September 2012, the spokesperson said on July 23.
According to Dairyland Power’s website, the project encompasses 20 miles of 161-kV transmission line between Genoa and La Crosse in western Wisconsin.
According to TransmissionHub data, the project is part of an effort to improve grid reliability in the region.
Dairyland Power said in its project fact sheet that the line, which is the primary electricity provider for the city of La Crosse and the surrounding areas, has been in critical need of rebuilding after almost 65 years of use and exposure to the elements.
The 161-kV Genoa to La Crosse segment of the Q1 line extends 20 miles from the Genoa substation in Vernon County north to a La Crosse interconnection with Xcel Energy (NYSE:XEL).
The line is being rebuilt, using existing routes and rights of way, due to age and condition, Dairyland Power said, noting that it was built circa 1949-1950 and has reached the end of its 60- to 65-year life.
Deterioration of the existing wood poles has the potential to affect safety and reliability, Dairyland Power said.
Modern engineering will allow the line, whose voltage will stay the same, to increase capacity and therefore delivery efficiency by more than 40%.
Overloading has been an ongoing concern with the line, which was reconductored in 1987 as a temporary solution to those concerns. “The work was completed to correct the potential overloading issue for 10 years; 25 years later, the line is finally being rebuilt,” Dairyland Power added.
The total project cost about $22.5m, and line rebuild included 113 structures consisting of 236 individual steel poles.
Dairyland Power is a Touchstone Energy Cooperative.
