From what I've been hearing a lot of power plants in texas have been falling offline because of frozen gas lines.
Power plants especially older ones in Texas are not built to perform well in these cold temperatures. It's like keeping your house pipes from freezing but this time way worse since a power plant has miles of pipe with liquid in them of differing freezing temperatures. If one section freezes which can happen very easily then the whole plant may come to a standstill and then stop producing electricity. And guess what else, most power plants can not start backup on their own, many plants require a grid with enough margin to turn back on.
Which brings me to another point, why the hell does Texas have their own power grid?!?? ERCOTS (Electric Reliability Council of Texas).
I mean I actually know why, they didn't want to abide by federal regulations and I guess texas cacs wanted to have a real chance to pump fake on secession back in the 70s but if they shared a grid with their neighboring states y'all would have power by now. The northeast and mid-atlantic grids share power during the stormy winter months all the time.
