Just as much of the country was experiencing record cold and massive travel disruptions, bad actors continued physical attacks against substations. As Robert Walton reports in Utility Dive, “Six substations in the Pacific Northwest were damaged by attacks in November, and the Federal Bureau of Investigation is looking into a North Carolina firearms attack … that knocked power out to about 45,000 Duke Energy customers.” In total, including a more recent incident this month, authorities are investigating an unprecedented 13 substation attacks over a period of just several weeks.
