Back in the early 90s I worked in a screen printing shop for a guy that was a former "NRC Armed Responder" at Diablo Canyon nuclear power plant in California in the mid 80s (he was also a former AP). Basically he patrolled the grounds with an M16 keeping an eye on things.

He said he routinely found holes cut in the fences surrounding the reactor building and every time he reported them he was ignored by both the security and the maintenance people.

Our power grid has been vulnerable for decades. I'm honestly surprised we haven't had a serious "grid down" event by now.
