The subject and question was specifically rolling blackouts and neither of those were rolling blackouts, so no, try again.

Of course failures happen, for example when I was living in Mountain View we had a blackout because a squirrel committed suicide by chewing through a high voltage cable. Or when I was living in Detroit, we were without power and heating for 3 days due to an ice storm. It was a pretty large (and long) outage, and we had freezing temperatures inside the house. Generators were sold out for 500 miles.

Ahh found it: 1985, 370K customers affected

Rolling blackouts are planned power outages because of insufficient capacity.

And note that these rolling blackouts are happening again and again.
