NV Energy's Rebuild of 60-Year-Old Transmission Line

May 31, 2017
NV Energy linemen conquered mountainous terrain, deep canyons and swampy ground.

Back in 1956, Sierra Pacific Power Co. constructed a new 60-kV transmission line from the town of Minden, Nevada, to Stateline, California, to serve the growing customer loads on the southeast shores of Lake Tahoe. Flash forward to 2016, and Sierra Pacific Power is now NV Energy, and the line that served its purpose for so many years has to be rebuilt.

Following are images of the construction process, all featured in T&D World's "Electric Utility Operations" section in May 2017. NV Energy linemen conquered mountainous terrain, deep canyons and swampy ground.
