As many in Texas wake up still without power on Thursday morning, millions are now also having to contend with water shutdowns, boil advisories, and empty grocery shelves as cities struggle with keeping infrastructure powered and supply chains are interrupted.

As of estimates performed on Wednesday, 7 million Texans were under a boil advisory. Since then, Austin has also issued a citywide water-boil notice due to power loss at their biggest water treatment plant. Austin Water serves over a million customers, according to its website.

With hundreds of thousands of people still without power in the state, some contending that they have no water coming out of their faucets at all, and others facing burst pipes leading to collapsed ceilings and other damage to their homes, the situation is dire for many Texans facing multiple problems at once.

Even as some residents are getting their power restored, the problems are only continuing to layer as the only grocery stores left open were quickly selling out of food and supplies. As many without power watched their refrigerated food spoil, lines to get into stores wrapped around blocks and buildings and store shelves sat completely empty with no indication of when new shipments would be coming in. Food banks have had to cancel deliveries and schools to halt meal distribution to students, the Texas Tribune reports.

People experiencing homelessness, including a disproportionate number of Black residents, have especially suffered in the record cold temperatures across the state. There have been some reports of people being found dead in the streets because of a lack of shelter.

“Businesses are shut down. Streets are empty, other than a few guys sliding around in 4x4s and fire trucks rushing to rescue people who turn their ovens on to keep warm and poison themselves with carbon monoxide,” wrote Austin resident Jeff Goodell in Rolling Stone. “Yesterday, the line at our neighborhood grocery store was three blocks long. People wandering around with handguns on their hip adds to a sense of lawlessness (Texas is an open-carry state).”

The Texas agricultural commissioner has said that farmers and ranchers are having to throw away millions of dollars worth of goods because of a lack of power. “We’re looking at a food supply chain problem like we’ve never seen before, even with COVID-19,” he told one local news affiliate.

An energy analyst likened the power crisis to the fallout of Hurricane Katrina as it’s becoming increasingly clear that the situation in Texas is a statewide disaster.

As natural gas output declined dramatically in the state, Paul Sankey, who leads energy analyst firm Sankey Research, said on Bloomberg, “This situation to me is very reminiscent of Hurricane Katrina…. We have never seen a loss [of energy supply] at this scale” in mid-winter. This is “the biggest outage in the history [of] U.S. oil and gas,” Sankey said.

Many others online echoed Sankey’s words as “Katrina” trended on Twitter, saying that the situation is similar to the hurricane disaster in that it has been downplayed by politicians but may be uncovered to be even more serious in the coming weeks.

Experts say that the power outages have partially been caused by the deregulation of the state’s electric grid. The government, some say, favored deregulatory actions like not requiring electrical equipment upgrades or proper weatherization, instead relying on free market mechanisms that ultimately contributed to the current disaster.

Former Gov. Rick Perry faced criticism on Wednesday when he said that Texans would rather face the current disaster than have to be regulated by the federal government. And he’s not the only Republican currently catching heat — many have begun calling for the resignation of Gov. Greg Abbott for a failure of leadership. On Wednesday, as millions suffered without power and under boil-water advisories, the governor went on Fox to attack clean energy, which experts say was not a major contributor to the current crisis, and the Green New Deal.

After declaring a state of emergency in the state over the weekend, the Joe Biden administration announced on Wednesday that it would be sending generators and other supplies to the state.

You ain’t foolin’ nobody with the lights out

WHEN IT RAINS, it pours, and when it snows, the lights turn off. Or so it goes in Texas. After a winter storm pummelled the Lone Star State with record snowfall and the lowest temperatures in more than 30 years, millions were left without electricity and heat. On February 16th 4.5m Texan households were cut off from power, as providers were overloaded with demand and tried to shuffle access to electricity so the whole grid did not go down.

Whole skylines, including Dallas’s, went dark to conserve power. Some Texans braved the snowy roads to check into the few hotels with remaining rooms, only for the hotels’ power to go off as they arrived. Others donned skiwear and remained inside, hoping the lights and heat would come back on. Across the state, what were supposed to be “rolling” blackouts lasted for days. It is still too soon to quantify the devastation. More than 20 people have died in motor accidents, from fires lit for warmth and from carbon-monoxide poisoning from using cars for heat. The storm has also halted deliveries of covid-19 vaccines and may prevent around 1m vaccinations from happening this week. Several retail electricity providers are likely to go bankrupt, after being hit with surging wholesale power prices.

Other states, including Tennessee, were also covered in snow, but Texas got the lion’s share and ground to a halt. Texans are rightly furious that residents of America’s energy capital cannot count on reliable power. Everyone is asking why.

The short answer is that the Electric Reliability Council of Texas (ERCOT), which operates the grid, did not properly forecast the demand for energy as a result of the storm. Some say that this was nearly impossible to predict, but there were warnings of the severity of the coming weather in the preceding week, and ERCOT’s projections were notably short. Brownouts last summer had already demonstrated the grid’s lack of excess capacity, says George O’Leary of Tudor, Pickering, Holt & CO (TPH), an energy investment bank.

Many Republican politicians were quick to blame renewable energy sources, such as wind power, for the blackouts, but that is not fair. Some wind turbines did indeed freeze, but natural gas, which accounts for around half of the state’s electricity generation, was the primary source of the shortfall. Plants broke down, as did the gas supply chain and pipelines. The cold also caused a reactor at one of the state’s two nuclear plants to go offline. Transmission lines may have also iced up, says Wade Schauer of Wood Mackenzie, an energy-research firm. In short, Texas experienced a perfect storm.

Some of the blame falls on the unique design of the electricity market in Texas. Of America’s 48 contiguous states, it is the only one with its own stand-alone electricity grid—the Texas Interconnection. This means that when power generators fail, the state cannot import electricity from outside its borders.

The state’s deregulated power market is also fiercely competitive. ERCOT oversees the grid, while power generators produce electricity for the wholesale market. Some 300 retail electricity providers buy that fuel and then compete for consumers. Because such cold weather is rare, energy companies do not invest in “winterising” their equipment, as this would raise their prices for consumers. Perhaps most important, the state does not have a “capacity market”, which would ensure that there was extra power available for surging demand. This acts as a sort of insurance policy so the lights will not go out, but it also means customers pay higher bills.

For years the benefits of Texas’s deregulated market structure were clear. At 8.6 cents per kilowatt hour, the state’s average retail price for electricity is around one-fifth lower than the national average and about half the cost of California’s. In 1999 the state set targets for renewables, and today it accounts for around 30% of America’s wind energy.

This disaster is prompting people to question whether Texas’s system is as resilient and well-designed as people previously believed. Greg Abbott, the governor, has called for an investigation into ERCOT. This storm “has exposed some serious weaknesses in our free-market approach in Texas”, says Luke Metzger of Environment Texas, a non-profit, who had been without power for 54 hours when The Economist went to press.

Wholly redesigning the power grid in Texas seems unlikely. After the snow melts, the state will need to tackle two more straightforward questions. The first is whether it needs to increase reserve capacity. “If we impose a capacity market here and a bunch of new cap-ex is required to winterise equipment, who bears that cost? Ultimately it’s the customer,” says Bobby Tudor, chairman of TPH. The second is how Texas can ensure the reliability of equipment in extreme weather conditions. After a polar vortex in 2014 hit the east coast, PJM, a regional transmission organisation, started making higher payments based on reliability of service, says Michael Weinstein of Credit Suisse, a bank. In Texas there is no penalty for systems going down, except for public complaints and politicians’ finger-pointing.

Texas is hardly the only state to struggle with blackouts. California, which has a more tightly regulated power market, is regularly plunged into darkness during periods of high heat, winds and wildfires. Unlike Texas, much of northern California is dependent on a single utility, PG&E. The company has been repeatedly sued for dismal, dangerous management. But, as in Texas, critics have blamed intermittent renewable power for blackouts. In truth, California’s blackouts share many of the same causes as those in Texas: extreme weather, power generators that failed unexpectedly, poor planning by state regulators and an inability (in California, temporary) to import power from elsewhere. In California’s blackouts last year, solar output naturally declined in the evening. But gas plants also went offline and weak rainfall lowered the output of hydroelectric dams.

In California, as in Texas, it would help to have additional power generation, energy storage to meet peak demand and more resilient infrastructure, such as buried power lines and more long-distance, high-voltage transmission. Weather events that once might have been dismissed as unusual are becoming more common. Without more investment in electricity grids, blackouts will be, too.
