As an Artic blast heads toward North Texas, bringing with it below freezing temperatures, ERCOT said it’s prepared to handle potential record breaking electricity demand. …

In the three years since the storm, more power plants have been winterized, natural gas producers have been put on lists to ensure their power stays on, and the overall electricity capacity in the state has increased.

But has it been enough?

[I can tell you that Texans are definitely asking the question, but the record-hot summer should give cause for confidence. The grid performed for a long period of sky-high demand with few if any systemic issues. As long as the winterizing has been accomplished at the producers and the nat-gas supply is as scalable as promised, we may only see local issues caused by ice and wind rather than the systemic failure of three years ago … just a few months before I moved here. — Ed]
