I'm not sure that this is correct. I was initially worried about how Mom would fare since she lives alone and is over 80. During the entire one week period of power problems in Feb. 2021 my Mom never lost power, not even a quick brown-out. Her home is within a half mile of a local hospital which also never lost power. The area around the hospital did not lose power so businesses and homes close by had no issues with heating, cooking, bathing, etc during the cold blast. That fact allowed me to stay here at my place a couple hours away and manage my own situation which was fairly easy compared to many others in the state.
Your other statements are quite true and to date no one who played a part in mismanagement of utility power in Texas has been held accountable nor will they ever be in a libertarian state where regulations exist only to guarantee a profitable situation for a commercial entity. In fact, most electricity customers in Texas ended up paying for the huge cost increases that occurred as those in charge tweaked the system in real time to maximize their own profits.
Texas needs regulations worse than most other states. Grifters, fraudsters, and thieves have filled too many critical positions for too long.
