The wind turbines need to be winterized, too.

They didn’t do as well as they should have, but they did a lot better than expected.

I recently heard a podcast with the CEO of MidAmerican (based in Iowa). They had materially colder temperatures than TX and operated 91% of their wind capacity. There's nothing inherent in wind that keeps it from operating in cold weather.

(MidAmerican did pay extra for winterization, so you can maybe make the argument that it wasn't worth it for TX to have done the same, given the risk profile.)
