I strongly object on comparing the Texas power grid with this wild-west stock exchange.

Deregulation of power grids (which has been done throughout the US, not only in Texas) isn't the same as removing red tape in financial reporting. It's about removing oversight of large, vertically-integrated utilities by fostering competition of unintegrated market participants.

Deregulating power grids has been such a success for flexibility and renewable energy integration that the European Union codified it into law in 2019.

Is it working perfectly in Texas? Absolutely not. Is it an example of utter failure of "deregulation"? Absolutely not!
