The high consumer rates in Texas were only with a few specific electricity providers that passed on spot prices (combined with Texas's lack of a capacity market (an implicit subsidy for wind) that caused spot prices to spike so much). I've no doubt that many people signed up for those plans not fully knowing what they were getting into. But I can also look at such a pricing structure and see how I could embrace it, assuming a reasonable time quantum and automatable ahead of time price notifications.
