"According to a report on grid security compiled by a power industry cyber clearinghouse, obtained by POLITICO, a total of 1,665 security incidents involving the U.S. and Canadian power grids occurred last year. That count included 60 incidents that led to outages, 71 percent more than in 2021." [0]
Uh, no. There have been a massive number of attacks attempting to take down the power grid. It's just that the protections in place are currently working most of the time.
Unfortunately, the official stats tends to combine both physical and cyber attacks, so there's no clear sense of which is dominant... But, frankly, there isn't a need to separate them. The attacks are happening.
