My wife works in ERCOT in IT and based on on what I'm hearing often, it is like any other gov related agency, slow, inneficient and lacks motivation. They are not directly responsible for grid or producers,but people blame them as such since they are middleman that suppose to manage things on the top level. Anyway, TX grid has a benefit of choice (think of MVNO resellers, that would be whom are called providers in TX). ONCOR for example is a distributor, they own and service powerlines, poles, wires and so on. And they is uncle Joe that built natural gas power station or windmills in his field-the producer. Providers just buy energy in bulk from producers on "market" and resell to you. Good thing there -competition. When we just moved to TX 5 years ago we had a plan with total price of 9.7c per kw. It just jumper to12.8 and I see now lowest16.4 and going up to 20+c (I use service that does everything for me, shopping around and connecting).This is a downside,providersare trying to recoullosses they occurred during snowpocalypsis, and this summer again (market price jumping to $5 per kw(now capped)). Another downside, since almost no regulation, Uncle Joe the producer will do what most businessman would do, spend less make more. Of course he will not winterize his gas wells and pipes. He does not give a sh&$ if his production will stop( I think now they will penalize them, but there was no significant punishment prior). As to huge bill in Dallas, maybe you friend had a contract with dynamic market price, those are outlawed now. Our friend just moved to San Jose and got fist bill, she was shocked to see about $500 for about 600kw. (Ours was $230 for 1770 kw due to long heat wave). Back when we lived in KY, we had a monopoly. 1 provider and you pay what they told you, no choice. I think I would better have a choice, and think about power backup solutions...
