You have suggested this twice as proof of actual rolling blackouts of any significant size, but for some reason fail to note that while SPP did order rolling blackouts to shave about 1.5% of the load within 50 minutes they rescinded this order and returned to EEA Level 2. Why fail to mention this I wonder?

(Not the parent poster) At a press conference, a SPP spokesperson said they had to cut up to 6.5% of load for 3h21m on Tuesday (Feb 16).

(Just wanting to set the record straight, under the SPP region myself. Given what I've seen, I'm pretty happy with how they've acted considering it could have looked like Texas. I wish there had been more and better communication with the public about the importance of conserving electricity but it's not like I followed their Twitter feed at the time.)

I know there were a few cuts because that let them get the load down, but when I first heard of blackouts outside of Texas they seemed to be of the 15-30 minute variety. Did not know they lasted more than an hour anywhere.
