Where I live, El Paso Electric lost 90% of its generating capacity during the cold snap. It dropped all the way down to 1 F here. Plant cooling systems froze solid and critical sensors stopped working. News footage showed large pipes and valve pedestals split like they were cloven with axes. Apparently, the city is now importing most of it's power from Palo Verde (In Arizona) which El Paso Electric owns a piece of.

We also had rolling black outs. Occasionally, the switching gear essentially froze in the off position and some areas were without power for more than the planned 45 minutes. Resultantly, pipes froze and houses flooded.

I escaped essentially unscathed. Only an irrigation anti-siphon value failed (I should have drained it but never have needed to before). Others in my office lost all water or had pipes break. One had his furnace fail. I feel very lucky.
