Back in 1989, the power companies across the state of Texas failed their customers during the winter. Severe cold caused failures of natural gas transmission systems to get fuel to power plants. Many plants with coal power were not winterized, and were taken off line as system after system failed.

Fast forward to 2011, and the same basic thing happened again. For over 20 years legislators and state government officials argued against requiring power companies to institute winterization standards common across the rest of the nation.

Ten years later, 2021, same thing again. Yes, in some places across Texas wind turbines have iced. Solar panels are not performing either due to accumulated snow and ice, or failure of switching equipment which is not prepared to deal with such cold temps.

But Texas has lost enough power generation capacity as coal and natural gas plants have gone off line, to supply power to over a million and a half homes.

We have not lost power lines in large numbers. The natural gas infrastructure is not getting fuel to many power plants. Plants are going off line because they piping systems are failing. Not protected against the cold. And while it is extreme for Texas, zero degrees is not a power generation emergency across most of the US.

Sorry for the rant, but third time I've heard the same thing, for the same reason. That the power companies in Texas cannot afford to take precautions that power companies across the nation have no trouble handling.

Are electricity prices fixed in TX or are they tied to the wholesale prices?

And they said go to wind and solar, that is what we need!! Doesn't seem to be that reliable to me. Had that problem (supply) in Colorado also!

Twenty mega watts plus is off the grid due to frozen turbines and all of them are now consuming power trying to keep from freezing.
If you depend on government or business for your security well.....
We don't have a back up generator yet but relatives do and in 2011 when without power for weeks they had power. We lose electricity we have the fire place.
Wife has cooked on the bbq grill on the car port at our last home. If your RV has a generator, having a plug installed and switch at the house a 10kw, preferably 15kw or larger onboard diesel generator and full tank of diesel would keep you warm.
A great advantage to owning a Mh if you have a garage for it near home.
Nothing else roll out the slides turn on the generator.
Everyone here young enough or in shape or with the finances needs to make arrangements for self sufficiency!

Texas is unusual in that almost the entire state is part of a single grid that lacks extensive integration with those of the surrounding states.

Since wind in Texas generally tends to produce less during winter, there's no way that the grid operators would have planned for getting 30GW from wind generation; in fact, a chart at ERCOT indicates that wind is producing significantly more than forecast.

So while having Texas' full wind-generating capacity online would help, the problems with meeting demand appear to lie elsewhere. An ERCOT director told Bloomberg that problems were widespread across generating sources, including coal, natural gas, and even nuclear plants. In the past, severe cold has caused US supplies of natural gas to be constrained, as use in residential heating competes with its use in generating electricity. But that doesn't explain the shortfalls in coal and nuclear, and the ERCOT executive wasn't willing to speculate.

Over 2 million Texans including RV campgrounds without electricity for heating due to frozen wind turbines. Many news sources on the Google News page. Texas gets almost one fourth of electricity from wind turbines. Admission was made by ERRC and owner/operator of the grid ERCOT.

According to many news sources on the Google News page the Texas Electrical Grid receives near one fourth of its electricity from wind turbines and they froze up hard during this severe ice and snow storm in the state. The admission was made by the state Energy Resource Reliability Council and also owner/operator of the grid ERCOT. Here is an Austin TV station source describing how at least 200,000 people in Austin area are without electricity for heating. People are having to boil water for purification in many locations.

Not a wind turbine problem; a problem with not preparing (investing) for low temperatures.
Quote:

Turbines in the Arctic Circle can work in temperatures as low as -30 degrees Celsius (-22 degrees Fahrenheit). And most turbine makers, from Vestas Wind Systems A/S and General Electric Co. are now able to offer versions of their units that come armed with ice mitigation systems and heating for some of the equipment.

More in-depth reading on the causes of the grid issue will show wind turbine shutdowns were partially offset by higher that typically production along the coast where there were no turbine shutdowns.
Quote:

AUSTIN AMERICAN-STATESMAN
As of Sunday morning, those iced turbines comprise 12,000 megawatts of Texas' installed wind generation capacity, although those West Texas turbines don't typically spin to their full generation capacity this time of year.

Fortunately for the Electric Reliability Council of Texas, which manages the state's electric grid, the storm's gusty winds are spinning the state's unfrozen coastal turbines at a higher rate than expected, helping to offset some of the power generation losses because of the icy conditions.

Severe weather, blackouts show the grid’........roblem is infrastructure, not renewables


Citing a market participant, Jenkins noted on Twitter that roughly 26 gigawatts of thermal energy is offline because natural gas is being diverted to provide heat instead of power. Only about 4 gigawatts of wind is offline because of icing, Jenkins noted.

This has not been a major icing event across Texas.

The number of powerlines down is minimal.

Funny, I'm sitting here with no interruption in either my electricity or natural gas service. Now that could change tonite as the possibility of ice storms instead of this snow , which we very seldom have snow and especially the 10 in in my yard. Not all of Tx is on that one grid, AEP-Swepco that supplies my electricity here at my house & also supplies the rural co-op at my little farm is on a totally different grid. My Son in Benbrook by FtWorth has not lost power either
Correct me if wrong but cities like Austin mandated heatpumps & no more natural gas heated homes so the electric demand went way up
