I was born and raised in Texas, and as much as I’ve grown tired of their shit, this is a vastly different situation to the last couple of power incidents they’ve had.
This was essentially a freak storm that came out of nowhere with something like a couple of hours of notice, spawned multiple tornadoes that took out a bunch of infrastructure, including at least one high-voltage transmission tower, and cut a path over a thousand miles, from Houston, Texas all the way to Cape Canaveral, Florida.
There are no regulations they’re circumventing by being in their own power grid that could have avoided this, and even being interconnected wouldn’t help much when the transmission lines have been ripped apart.
