LAKE TAHOE, Calif. – It wasn’t just another day at the office this summer for crews with Liberty as they replaced nearly two miles of power lines and rebuilt the electrical circuit in a remote, difficult-to-access area.
Rebuilding power lines in rugged mountain terrain was no easy task, but for a stronger electric system, more reliable service, and reduced wildfire risk, Liberty says it was worth the challenge.
Aging equipment was replaced with new utility poles and covered conductor, which provides added protection against vegetation contact, weather, and other conditions that can contribute to power outages or potential wildfire ignition. Power lines were also rerouted away from structures and sensitive wetland areas to improve safety and reduce environmental impacts.
Because of the challenging mountain terrain, helicopters were used to transport materials and assist with construction. In total, 65 new poles were installed for this project, with approximately 75 percent of them set by helicopter.
In addition to electric system upgrades, Liberty worked closely with the U.S. Forest Service and Tahoe Regional Planning Agency to improve forest health and reduce potential fuels near critical infrastructure. Crews removed hazardous trees, pruned vegetation, and used helicopters to remove more than 300 tons of biomass from the utility right-of-way.
“These efforts help reduce the risk of a wildfire ignition by removing vegetation that could contribute to wildfire spread as well as creating increased clearance around electric equipment,” said Liberty in a statement. “Together, the infrastructure improvements and vegetation management work create a stronger, more resilient electric system that is better positioned to reduce wildfire risk and continue providing reliable service for residents and visitors in the Angora Lakes area.”
