It's still ongoing for millions at the moment but there was a nice map in https://www.usatoday.com/in-depth/news/nation/2021/02/16/tex... for this morning.

It will be interesting to see which communities had their power cut and which were barely affected

There was a rather morbid photograph on one of the local news sites the other night of Austin looking south along I-35 during the rolling blackouts. The East Side was more or less pitch black. The west side - downtown, the capitol, the stadium, the Frost Bank building etc - was lit up like a Christmas tree.

The east side was created by redlining policies put in place 100 years ago, and is where much of Austin’s lower income population lives.

It wasn’t meant to be a comprehensive statistical analysis but it was a pretty stark photo.

About half of Austin has been out for 42 hours now. Source: I’m one of them.

That's ridiculous. I always thought the point of rolling blackouts was to make sure no one area was without power for too long.

Rolling only works for demand overages of up to 20% or so. With a loss of generation capacity of over 1/3rd of generation that is out the window.

They were trying to keep the grid alive and not have a statewide blackout.
