After saying for several years that underground the installation of high-voltage, long distance electrical transmission lines was too expensive, Pacific Gas & Electric has changed course. On July 22, the utility giant announced plans to bury as much as 10,000 miles of its electrical transmission lines underground in fire-prone areas of California. Cost is estimated to be $20 billion over the course of a decade or more. The move was prompted by the catastrophic damages, lawsuits and bankruptcy PG&E suffered after wildfires caused by sparking electrical lines swept through Northern California in 2017 and 2018. The move is not only good news for contractors and residents of California but highlights an apparent change in thinking about the need to harden critical infrastructure. The timing of the announcement came just a week before the U.S. Senate agreed to authorize a massive $1-trillion-dollar infrastructure bill, of which $73 billion is earmarked to modernize the nation’s electrical grid and $50 billion is allocated to protecting infrastructure against climate change and cyber-attacks. “Our goal is 10,000 additional miles of overhead lines converted to underground,”
