PG&E will spend up to $30 billion burying power lines

Pacific Gas & Electric plans to bury 10,000 miles of its power lines in an effort to prevent its fraying grid from sparking wildfires when electrical equipment collides with millions of trees and other vegetation

SAN RAMON, Calif. -- Pacific Gas & Electric plans to bury 10,000 miles (16,000 kilometers) of its power lines in an effort to prevent its fraying grid from sparking wildfires when electrical equipment collides with millions of trees and other vegetation across drought-stricken California. The daunting project announced Wednesday aims to bury about 10% of PG&E's distribution and transmission lines at a projected cost of $15 billion to as much as $30 billion, based on how much the process currently costs. The utility believes it will find ways to keep the final bill at the lower end of those estimates. Most of the costs will likely be shouldered by PG&E customers, whose electricity rates are already among the highest in the U.S. PG&E stepped up its safety commitment just days after informing regulators a 70-foot (23-meter) pine tree that toppled on one of its power lines ignited a major fire in Butte County, the same rural area about 145 miles (233 kilometers) northeast of San Francisco where another fire sparked by its equipment in 2018 killed more than 80 people and destroyed thousands of homes. Since it started July 13 in a remote area of Butte County, the Dixie Fire has churned northeast through the Sierra Nevada. By Wednesday, the fire spanned a 133-square-mile (344-square-kilometer) area, forcing the Plumas County sheriff on Wednesday to order evacuations along the west shore of popular Lake Almanor.
