A US Senator’s job isn’t within the border of the state, but in Washington DC. So this isn’t in his “jurisdiction”, so to speak. Ercot, and it’s related issues is a job for State Reps and Senators.
You're ignoring the fact that one of the reasons ERCOT exists is because Texas has made every effort to keep national oversight out of the Texas power grid. ERCOT very much is a state vs national issue, and Ted Cruz absolutely had a hand in it. Why do you think Cruz has a history of mocking California's energy policies? Because he,
as a senator, has played a role in making ERCOT the problem that it is.
Everyone is trying to get some overhaul work done after quick repairs done back in February.
Yes, that's one major part of the problem.
Everyone is trying to get maintenance work done. Maintenance is done on a schedule that maximizes profits, not reliability. That was one of the major factors in why the grid nearly collapsed earlier this year, and why it continues to be a danger. The system is not structured as an essential utility, it's structured as a cash cow.
Would everyone be happier if they’d just ignored it and had the power go out again? Maybe killed a few workers at the plants when they went into emergency reconnect without warning? Everything ERCOT does right now will get extra scrutiny, with reason, but last year or the year before the same announcement wouldn’t have gotten even a glance by the news because it wasn’t “news.”
Just because it wouldn't have captured headlines doesn't mean it wouldn't have been an important symptom of a failing system.
"I don't know why everyone is worried my blood glucose levels right now. Just because I got diagnosed with diabetes, every meal gets extra scrutiny. If I'd been thirsty and gotten headaches last year no one would have given it a second thought."
Yeah, people might have missed the important symptoms before, but that doesn't mean they aren't important.
