What part of Texas do you live in? Or, do you? It's been triple digits here for many days, and I'm having no trouble running the A/C.
The last few years there have been constant threats, warning not to charge electric cars, badgering, requests and smart meters to shut off air conditioning in the heat. The freeze out of 2021 killed 246 people.
When I was growing up, in the Reddy Kilowatt days and electric companies and co-ops with no central control, the power -never- failed unless a storm took the lines down.
But you seem satisfied with ERCOT and windmills and zero reserve capacity.
