In the aftermath of the Texas power failures in February, a number commenters found confirmation that, amazingly, they had been right about everything all along. Thus, those who were against wind power and renewable energy mandated in general blamed the wind farms. Those who are suspicious of competition in markets for generating electrical power blamed deregulation, although blaming "the market" for what happens in a heavily regulated industry seems peculiar to me. Some critics even blamed Enron, a company that has not existed for years. What actually happened seems simpler, if less reinforcing for various preconceptions: It got really cold.Michael Giberson provides an overview in "Texas Power Failures: What happened in February 2021 and What Can be Done" (Reason Foundation, April 2021). He describes the weather:
The temperature in Dallas dipped to -2° F, the coldest it had been in Dallas for 70 years. Snow fell on the beaches on the Gulf Coast at Galveston, south of Houston. Temperatures in Austin remained below freezing for six days at a time of when temperatures usually average in the mid-50s. At Brownsville, near the most southern tip of Texas, February weather typically averages 65° F. High temperatures in Brownsville were in the mid-80s just days before the cold. The temperature in the city did not rise above freezing for nearly 48 hours once the cold settled in. For the first time in history all 254 counties in Texas were under a winter storm warning at the same time. The cold was not unprecedented at any particular location, but it was extreme, widespread, and long lasting in February 2021. ...
The cold affected more than the ERCOT power system. Some power systems in Texas not within the ERCOT system also resorted to rolling outages. Natural gas production and distribution froze up. Municipal water mains froze in cities across the South. Ranchers in the Panhandle lost cattle to the cold. Citrus growers in South Texas saw damage to trees that may last for years. Roads were closed due to ice and storms. Failures were not solely an electric power industry concern or a natural gas failure. The cold was simply worse than almost anyone in Texas was prepared for. ... Clearly, it was not negligent on ERCOT’s part—and maybe anyone’s part—to fail to anticipate such anomalous temperatures.
The Texas power emergency lasted about four days: at its worst, about 4.5 million people were without power.
Hindsight is 20:20, but now that Texas has been warned by experience, the case for some mixture of these actions is strong. Garrett Golding, Anil Kumar and Karel Mertens at the Dallas Federal Reserve offer some estimates in "Cost of Texas’ 2021 Deep Freeze Justifies Weatherization" (Dallas Fed Economics blog, April 15, 2021). In measuring economic losses from the power outage, they write:
The power outages led to widespread damage to homes and businesses, foregone economic activity, contaminated water supplies and the loss of at least 111 lives. Early estimates indicate that the freeze and outage may cost the Texas economy $80 billion–$130 billion in direct and indirect economic loss. These initial calculations come with significant uncertainty. Estimates of insured losses, which are easier to quantify, range from $10 billion to $20 billion.In terms of what steps might be taken, they note:
Winterizing standards on new oil and gas wells may offer a targeted and effective approach in the long run. Due to the high initial productivity of shale wells, new wells will eventually make up a large share of overall production. Many companies already implement winterizing measures. With winterizing equipment costing between $20,000 and $50,000 per well, we estimate these measures statewide would total $85 million–$200 million annually. A large and perhaps inexpensive fix would be prioritizing electricity delivery to gas infrastructure. If power plant and pipeline operators improve coordination to identify and constantly monitor the gas infrastructure requiring such prioritization, some of the problems experienced during the freeze could be prevented.
It's also possible to winterize the wind farms that received so much attention. They write about the possibilities of "upgraded blade coatings, cold-weather lubricants and de-icing drones."
Overall, the lesson here seems to be to move past the blame game, to accept that the cold weather snap was unprecedented, and now to have Texans pay a little more for electricity to fund these kinds of steps.
