According to recent reports, the FBI is investigating similar attacks in Washington and Oregon in November.
The Seattle Times reported that Puget Sound Energy, the Cowlitz County Public Utility District, and Bonneville Power Administration (BPA) have all said they are cooperating with a federal investigation into the attacks. However, the FBI has declined to confirm that it is conducting such an investigation.
An internal federal law enforcement memo warning of the recent attacks has been obtained exclusively by NewsNation.
“Power companies in Oregon and Washington have reported physical attacks on substations using hand tools, arson, firearms and metal chains possibly in response to an online call for attacks on critical infrastructure… In recent attacks, criminal actors bypassed security by cutting the fence links, lighting nearby fires, shooting equipment from a distance or throwing objects over the fence and onto equipment,” according to the memo.
