Did anyone else also lose water or did my water pipe froze solid? I had my faucet drip. We still had water around 1 AM. Now we don't. I live in 77077...

We have no electricity in 77035

I doubt these are voluntary rolling blackouts. This seems involuntary.

All utilities still on at the western end of 77079. We can handle a ~1-2 hour blackout but any longer than that and I'm firing up the generator.

It's remarkable that our grid can keep up with 110 degree summer days but is struggling with this cold snap. I guess for all-electric homes, heat pumps + backup electric elements use about as much power as ACs?

It may be that with heat, many people can get by on fans alone, or open windows, but electric heating elements require a lot of wattage to get red hot. An electric heater is a controlled short circuit.

It’s a supply issue - not demand. Current ERCOT demand of 50,000 MW is nowhere near record summer peak demand of 75,000 MW

I started having short power outages around midnight. But eventually my gas heaters ran all night (they need some electricity for the motors).
Last night was just a beginning though.
At least it's sunny today...

Power is back up here (Gessner @ Clay) at about 9:30 am. 4 hours without juice temp in the house dropped from 70 to 55 in the hour since power was restored I'm back to 65. Called a friend in 77080 near Gessner and Hammerly his power was cut at 4 am and he is still without , but does have a back up generator.

There is a loss of generating capacity. Half the wind power is down due to turbine freezing, and I suspect some gas plants have been curtailed due to a shortage of gas capacity.
