Texas had no power because they forgot everything they learnt the hard way from their "once-in-a-decade snow storm" they had 2011.
Coal piles freezing solid because there is no roof, gas valves impossible to operate because nobody would put a box around them, no water too cool reactor cores because the pipes froze: these are not failures somehow cascading from the fact they build some windmills.
When I learnt that turbines on Texas nuclear plants stay under the open sky I was REALLY surprised. It was the reason behind the single failure, otherwise nuclear plants have weathered this crisis perfectly.
I guess the lesson is that not even Texans think nuclear is so safe it doesn't need weather protection, or maybe it's some pesky federal regulation that says that at least the reactor needs to be protected...
