In California, meanwhile, mounting temperatures contributed to rolling blackouts in the summer of 2020, the point out’s initially this kind of outages in nearly 20 years.
Moreover, the escalating reliance of the grid on electronic systems will increase the potential of cyberattacks. New reports from your U.S. Govt Accountability Business alert the grid’s generation, transmission, and distribution systems are all progressively prone to cyber intrusions. Because the 1970s, grid operators have relied on Digital industrial Handle (IC) centers that happen to be frequently unsecured versus malware including the Stuxnet virus, which focused Iranian nuclear amenities in 2010.
