I’m a little annoyed that my client apparently didn’t show me this post yesterday.

I’m nominally familiar with utility scale issues and it appears the fault here lie with the lack of regulatory environment in Texas.
There’s a process called “Line Clearing” where utilities send crews to cut down branches or sometimes whole trees if they pose a risk to power lines. Line clearing mostly impacts local circuits. Circuits are neighborhood level, and those power lines are lower than other kinds of power lines. Schedules for line clearing are often set with regulatory bodies, but can be left to utilities to set.

Because line clearing means that crews have to traverse every power line on the grid, it’s often not something that utilities want to do. If given a say in the regulatory process or left to their own devices, they’ll opt for as long of a span between line clearings as possible.

What’s that mean, now that I’ve written so much? Well, it means that when big storms come through, the failure point isn’t necessarily the transmission lines or the power stations. It’s the local lines, disconnecting individual houses, streets, or entire neighborhoods. Instead of a few fixes here and there to get the grid back up, it’s a lot of fixes everywhere, which is time consuming and expensive. It means that ‘everyday’ failures are more common as trees can rot out and randomly collapse.
And, sure - those everyday fixes are relatively easy to deal with individually, but in a situation where a lot of those issues accumulate at once, they can cause other, more serious issues on the grid, as well as creating a massive backlog to work through.

It’s sort of a foundational regulatory problem that seems to not have been addressed. A lot of midwestern states can bear wind storms with minimal problems - because their grid standards are written with lots of wet snow in mind.

Which is all to say, it’s supply, demand, delivery, and all the trappings therein, too.
I think on those grounds, criticism of Texas’ grid stands.
