PORTLAND, Oregon — A jury in Oregon on Monday found the electric utility PacifiCorp responsible for causing devastating fires during Labor Day weekend in 2020, ordering the company to pay tens of millions of dollars to 17 homeowners who sued and finding it liable for broader damages that could push the total award into the billions. …The property owners, suing on behalf of a class of thousands of others, alleged that PacifiCorp negligently failed to shut off power to its 600,000 customers during a windstorm, despite warnings from then-Gov. Kate Brown’s chief-of-staff and top fire officials, and that its power lines were responsible for multiple blazes. There has been no official cause determined for the Labor Day fires, which killed nine people, burned more than 1,875 square miles in Oregon, and destroyed upward of 5,000 homes and structures. The blazes together were one of the worst natural disaster’s in Oregon history. …PacifiCorp immediately said it would appeal.
