California has a power grid that doesn't immediately fail when it gets too cold or too hot. No, californian power utilities just kills 12 people each year and regularly starts forest fires.
I'll be honest, this summer hasn't had any rolling blackouts in North Texas. Oh, I bet it has nothing to do with the expanded wind/solar/battery farms. Can't be the renewables!
In the case of the '18 February snap-freeze, the problem was gas plant lines freezing over so they couldn't run their generators as demand peaked.
Ironically, that sky-high crisis pricing causes green energy investment to surge, as wind and solar got to ride the $3000 Mwh rates during the peak of summer while gas companies had to spend a small fortune retrofitting all their lines.
Actually, I think CA regularly has more power outages than Texas. https://poweroutage.us/
Though I'm not sure how many people your utilities are found to manslaughter in a given year.
