> ERCOT actually does a pretty okay job, all things considered; it's hard to invest heavily in winterization for rare events when you're having to invest heavily in new generation to keep up with steadily increasing baseline load.

I'm going to have to strongly disagree here. It's particularly easy when you have to invest heavily in new generation to keep up with steadily increasing baseline load. Retrofitting winterization is more expensive. If you build in support for winterization when you build the capacity in the first place (which is what happens with sane regulatory oversight), it's all quite inexpensive. It'd be one thing if the cold was a once a century surprise, but when you know you're going to have cold events multiple times over the lifetime of your equipment, it's really easy to do this right.

Considering how much the Texas state government has been illegally trampling its own residents’ rights recently, mostly for the sake of private corruption, and backed by incredibly bad faith anti-social rhetoric, perhaps reflexive anti-Texas-elected-officials-ism is a reasonable baseline position.

I don't think their comment was either ignorant or anti-Texan. Essentially all of the conclusions in the FERC report on the February 2021 events were those of regulatory failure. Generating assets did not have winterization plans that state inspectors actually enforced, most of the failed assets failed at temperatures above their design minima, natural gas delivery system were totally deregulated at the state level, ERCOT winter forecast practices were poor, etc.
