IIRC the reason Texas cannot get 'assistance' from other states is that the feds made it illegal to connect to most interstate grids without following their regulatory regimes. I believe Texas does connect to Mexico and possible some other regional grids although I don't really understand the exemption for those.

In this case it's not really Texas 'not allowing' other states to help but the other states not allowing Texas. Conceivably federal law could be updated to remove those regulations and Texas would absolutely connect to the interstate grid at that point.

That, of course, ignores the fact that those regulations are in place for a reason. Texas refuses to play by the rules, and the impact of that is that they don't get help when it's important. It is unfortunate, but a direct consequence of the choices they made.

The Texas Interconnection does tie in to surrounding grids through DC-ties. Those are limited in how much power can be sent through them and ultimately isolate the AC frequency.

Rules like hardening your system to be resilient in high or low temperatures.

Super abusive. Let’s do away with safety systems that literally save human lives. Heck Texas doesn’t like them so let’s do away with them for the whole nation? How many people died during the last couple heat and cold induced grid outages in Texas? I lost count after a couple dozen. But those people were weak or poor anyway right? Texas strong!
