How has the Texas grid improved since Winter Storm Uri in 2021? Getty Images

Houstonians may feel anxious as the city and state brace for additional freezing temperatures this winter. Every year since 2021’s Winter Storm Uri, Texans wonder whether the grid will keep them safe in the face of another winter weather event. The record-breaking cold temperatures of Uri exposed a crucial vulnerability in the state’s power and water infrastructure.

According to ERCOT’s 6-day supply and demand forecast from January 3, 2025, it expected plenty of generation capacity to meet the needs of Texans during the most recent period of colder weather. So why did the grid fail so spectacularly in 2021?

  1. Demand for electricity surged as millions of people tried to heat their homes.
  2. ERCOT was simply not prepared despite previous winter storms of similar intensity to offer lessons in similarities.
  3. The state was highly dependent on un-winterized natural gas power plants for electricity.
  4. The Texas grid is isolated from other states.
  5. Failures of communication and coordination between ERCOT, state officials, utility companies, gas suppliers, electricity providers, and power plants contributed to the devastating outages.

The domino effect resulted in power outages for millions of Texans, the deaths of hundreds of Texans, billions of dollars in damages, with some households going nearly a week without heat, power, and water. This catastrophe highlighted the need for swift and sweeping upgrades and protections against future extreme weather events.

Texas State Legislature Responds

Texas lawmakers proactively introduced and passed legislation aimed at upgrading the state’s power infrastructure and preventing repeated failures within weeks of the storm. Senate Bill 3 (SB3) measures included:

  • Requirements to weatherize gas supply chain and pipeline facilities that sell electric energy within ERCOT.
  • The ability to impose penalties of up to $1 million for violation of these requirements.
  • Requirement for ERCOT to procure new power sources to ensure grid reliability during extreme heat and extreme cold.
  • Designation of specific natural gas facilities that are critical for power delivery during energy emergencies.
  • Development of an alert system that is to be activated when supply may not be able to meet demand.
  • Requirement for the Public Utility Commission of Texas, or PUCT, to establish an emergency wholesale electricity pricing program.

Texas Weatherization by Natural Gas Plants

In a Railroad Commission of Texas document published May 2024 and geared to gas supply chain and pipeline facilities, dozens of solutions were outlined with weatherization best practices and approaches in an effort to prevent another climate-affected crisis from severe winter weather.

Some solutions included:

  • Installation of insulation on critical components of a facility.
  • Construction of permanent or temporary windbreaks, housing, or barriers around critical equipment to reduce the impact of windchill.
  • Guidelines for the removal of ice and snow from critical equipment.
  • Instructions for the use of temporary heat systems on localized freezing problems like heating blankets, catalytic heaters, or fuel line heaters.

According to Daniel Cohan, professor of environmental engineering at Rice University, power plants across Texas have installed hundreds of millions of dollars worth of weatherization upgrades to their facilities. In ERCOT’s January 2022 winterization report, it stated that 321 out of 324 electricity generation units and transmission facilities fully passed the new regulations.

Is the Texas Grid Adequately Winterized?

Utilities, power generators, ERCOT, and the PUCT have all made changes to their operations and facilities since 2021 to be better prepared for extreme winter weather. Are these changes enough? Has the Texas grid officially been winterized?

This season, as winter weather tests Texans, residents may potentially experience localized outages. When tree branches cannot support the weight of the ice, they can snap and knock out power lines to neighborhoods across the state. In the instance of a downed power line, we must rely on regional utilities to act quickly to restore power.

The specific legislation enacted by the Texas state government in response to the 2021 disaster addressed to the relevant parties ensures that they have done their part to winterize the Texas grid.

Reshaping the Texas grid: The impact of EVs, AI, renewables, and extreme weather

guest column

Did you catch those images of idle generators that CenterPoint had on standby during Hurricane Beryl? With over 2 million people in the Houston area left in the dark, many were wondering, "if the generators are ready, why didn’t they get used?" It seems like power outages are becoming just as common as the severe storms themselves.

But as Ken Medlock, Senior Director of the Baker Institute Center for Energy Studies (CES) explains, it's not a simple fix. The outages during Hurricane Beryl were different from what we saw during Winter Storm Uri. This time, with so many poles and wires down, those generators couldn’t be put to use. It’s a reminder that each storm brings its own set of challenges, and there’s no one-size-fits-all solution when it comes to keeping the lights on. While extreme weather is one of the leading threats to our electric grid, it's certainly not the only one adding strain on our power infrastructure.

The rapid rise of artificial intelligence (AI) and electric vehicles (EVs) is transforming the way we live, work, and move. Beneath the surface of these technological marvels lies a challenge that could define the future of our energy infrastructure: they all depend on our electrical grid. As AI-powered data centers and a growing fleet of EVs demand more power than ever before, our grid—already under pressure from extreme weather events and an increasing reliance on renewable energy—faces a critical test. The question goes beyond whether our grid can keep up, but rather focuses on how we can ensure it evolves to support the innovations of tomorrow without compromising reliability today. The intersection of these emerging technologies with our aging energy infrastructure poses a dilemma that policymakers, industry leaders, and consumers must address.

Julie Cohn, Nonresident Fellow at the Center for Energy Studies at the Baker Institute for Public Policy, presents several key findings and recommendations to address concerns about the reliability of the Texas energy grid in her Energy Insight. She suggests there’s at least six developments unfolding that will affect the reliability of the Texas Interconnected System, operated by the Electric Reliability Council of Texas (ERCOT) and the regional distribution networks operated by regulated utilities.

Let’s dig deeper into some of these issues:

AI

AI requires substantial computational power, particularly in data centers that house servers processing vast amounts of data. These data centers consume large amounts of electricity, putting additional strain on the grid.

According to McKinsey & Company, a single hyperscale data center can consume as much electricity as 80,000 homes combined. In 2022, data centers consumed about 200 terawatt-hours (TWh), close to 4 percent, of the total electricity used in the United States and approximately 460 TWh globally. That’s nearly the consumption of the entire State of Texas, which consumed approximately 475.4 TWh of electricity in the same year. However, this percentage is expected to increase significantly as demand for data processing and storage continues to grow. In 2026, data centers are expected to account for 6 percent, almost 260 TWh, of total electricity demand in the U.S.

EVs

According to the Texas Department of Motor Vehicles, approximately 170,000 EVs have been registered across the state of Texas as of 2023, with Texas receiving $408 million in funding to expand its EV charging network. As Cohn suggests, a central question remains: Where will these emerging economic drivers for Texas, such as EVs and AI, obtain their electric power?

EVs draw power from the grid every time they’re plugged in to charge. This may come as a shock to some, but “the thing that’s recharging EV batteries in ERCOT right now, is natural gas,” says Medlock. And as McKinsey & Company explains, the impact of switching to EVs on reducing greenhouse gas (GHG) emissions will largely depend on how much GHG is produced by the electricity used to charge them. This adds a layer of complexity as regulators look to decarbonize the power sector.

Depending on the charger, a single EV fast charger can pull anywhere from 50 kW to 350 kW of electricity per hour. Now, factor in the constant energy drain from data centers, our growing population using power for homes and businesses, and then account for the sudden impact of severe environmental events—which have increased in frequency and intensity—and it’s clear: Houston… we have a problem.

The Weather Wildcard

Texas is gearing up for its 2025 legislative session on January 14. The state's electricity grid once again stands at the forefront of political discussions. The question is not just whether our power will stay on during the next winter storm or scorching summer heatwave, but whether our approach to grid management is sustainable in the face of mounting challenges. The events of recent years, from Winter Storm Uri to unprecedented heatwaves, have exposed significant vulnerabilities in the Texas electricity grid, and while legislative measures have been taken, they have been largely patchwork solutions.

Winter Storm Uri in 2021 was a wake-up call, but it wasn’t the first or last extreme weather event to test the Texas grid. With deep freezes, scorching summers, and unpredictable storms becoming the norm rather than the exception, it is clear that the grid’s current state is not capable of withstanding these extremes. The measures passed in 2021 and 2023 were steps in the right direction, but they were reactive, not proactive. They focused on strengthening the grid against cold weather, yet extreme heat, a more consistent challenge in Texas, remains a less-addressed threat. The upcoming legislative session must prioritize comprehensive climate resilience strategies that go beyond cold weather prep.

“The planners for the Texas grid have important questions to address regarding anticipated weather extremes: Will there be enough energy? Will power be available when and where it is needed? Is the state prepared for extreme weather events? Are regional distribution utilities prepared for extreme weather events? Texas is not alone in facing these challenges as other states have likewise experienced extremely hot and dry summers, wildfires, polar vortexes, and other weather conditions that have tested their regional power systems,” writes Cohn.

Renewable Energy and Transmission

Texas leads the nation in wind and solar capacity (Map: Energy, Environment, and Policy in the US), however the complexity lies in getting that energy from where it’s produced to where it’s needed. Transmission lines are feeling the pressure, and the grid is struggling to keep pace with the rapid expansion of renewables. In 2005, the Competitive Renewable Energy Zones (CREZ) initiative showed that state intervention could significantly accelerate grid expansion. With renewables continuing to grow, the big question now is whether the state will step up again, or risk allowing progress to stall due to the inadequacy of the infrastructure in place. The legislature has a choice to make: take the lead in this energy transition or face the consequences of not keeping up with the pace of change.

Conclusion

The electrical grid continues to face serious challenges, especially as demand is expected to rise. There is hope, however, as regulators are fully aware of the strain. While our grid may be showing its age, this is the perfect time to shift from reacting to problems to getting ahead of them.

As Cohn puts it, “In the end, successful resolution of the various issues will carry significant benefits for existing Texas industrial, commercial, and residential consumers and have implications for the longer-term economic attractiveness of Texas. Suffice it to say, eyes will be, and should be, on the Texas legislature in the coming session.”

Oklahoma sues 2 Texas natural gas companies over price spikes during 2021 winter storm

taking action

Two Texas-based natural gas companies are being sued by Oklahoma, which alleges they fraudulently reduced gas supplies to send prices soaring during Winter Storm Uri, making huge profits while thousands shivered across the state.

The lawsuits are Oklahoma's first against natural gas operators over earnings during the 2021 storm. The suits were filed against Dallas-based ET Gathering & Processing, which acquired Enable Midstream Partners in 2021, and Houston-based Symmetry Energy Solutions.

Both lawsuits seek actual and punitive damages, as well as a share of any profits that resulted from wrongdoing. Oklahoma's Republican attorney general, Gentner Drummond, said his office intends to pursue additional litigation against other companies that may have engaged in market manipulation.

“I believe the level of fraud perpetrated on Oklahomans during Winter Storm Uri is both staggering and unconscionable,” Drummond said in a statement. “While many companies conducted themselves above board during that trying time, our analysis indicates that some bad actors reaped billions of dollars in ill-gotten gains."

A Symmetry spokesperson said in a statement that the company "adamantly denies the unfounded allegations in the lawsuit, which it will vigorously defend.” A message seeking comment left with ET was not immediately returned. The lawsuits were filed in Osage County, Oklahoma.

The devastating storm sent temperatures plummeting across the country and left millions of people without power.

Kansas Attorney General Kris Kobach filed a similar lawsuit in federal court in December against a natural gas marketer operating in that state. In Texas, which was also hit hard by the deadly storm, the electric utility Griddy Energy reached a settlement with state regulators over crushing electric bills its customers received.

Houston geothermal company secures major power purchase agreement with Shell

under contract

Beginning in 2026, Shell will be able to apply 31 megawatts of 24/7 carbon-free geothermal power to its customers thanks to a new 15-year power purchase agreement with Houston next-gen geothermal development company Fervo Energy.

“This agreement demonstrates that Fervo is stepping up to meet the moment,” Dawn Owens, VP, Head of Development & Commercial Markets at Fervo, said in a news release.

Shell will become the first offtaker to receive electrons from Fervo's flagship geothermal development in Beaver County, Utah’s Phase I of Cape Station. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026.

Cape Station will increase from 400 MW to 500 MW, which is considered by the company a major accomplishment due to recent breakthroughs in Fervo’s field development strategy and well design. Fervo is now able to generate more megawatts per well by optimizing well spacing using fiber optic sensing, increasing casing diameter and implementing staggered bench development. This can allow for a 100 MW capacity increase without the need for additional drilling, according to the company.

With the addition of the new Shell deal, all 500 MW of capacity from Fervo’s Cape Station are now fully contracted. The deal also includes existing agreements, like Fervo’s PPAs with Southern California Edison and an expanded deal with Clean Power Alliance that adds 18 MW of carbon-free geothermal energy to the company’s existing PPA with Fervo.

“As customers seek out 24/7 carbon-free energy, geothermal is clearly an essential part of the solution,” Owens said in the release.

Houston expert: From EVs to F-35s — materials that power our future are in short supply

guest column

If you’re reading this on a phone, driving an EV, flying in a plane, or relying on the power grid to keep your lights on, you’re benefiting from critical minerals. These are the building blocks of modern life. Things like copper, lithium, nickel, rare earth elements, and titanium, they’re found in everything from smartphones to solar panels to F-35 fighter jets.

In short: no critical minerals, no modern economy.

These minerals aren’t just useful, they’re essential. And in the U.S., we don’t produce enough of them. Worse, we’re heavily dependent on countries that don’t always have our best interests at heart. That’s a serious vulnerability, and we’ve done far too little to fix it.

Where We Use Them and Why We’re Behind

Let’s start with where these minerals show up in daily American life:

  • Electric vehicles need lithium, cobalt, and nickel for batteries.
  • Wind turbines and solar panels rely on rare earths and specialty metals.
  • Defense systems require titanium, beryllium, and rare earths.
  • Basic infrastructure like power lines and buildings depend on copper and aluminum.

You’d think that something so central to the economy, and to national security, would be treated as a top priority. But we’ve let production and processing capabilities fall behind at home, and now we’re playing catch-up.

The Reality Check: We’re Not in Control

Right now, the U.S. is deeply reliant on foreign sources for critical minerals, especially China. And it’s not just about mining. China dominates processing and refining too, which means they control critical links in the supply chain.

Gabriel Collins and Michelle Michot Foss from the Baker Institute lay all this out in a recent report that every policymaker should read. Their argument is blunt: if we don’t get a handle on this, we’re in trouble, both economically and militarily.

China has already imposed export controls on key rare earth elements like dysprosium and terbium which are critical for magnets, batteries, and defense technologies, in direct response to new U.S. tariffs. This kind of tit-for-tat escalation exposes just how much leverage we’ve handed over. If this continues, American manufacturers could face serious material shortages, higher costs, and stalled projects.

We’ve seen this movie before, in the pandemic, when supply chains broke and countries scrambled for basics like PPE and semiconductors. We should’ve learned our lesson.

We Do Have a Stockpile, But We Need a Strategy

Unlike during the Cold War, the U.S. no longer maintains comprehensive strategic reserves across the board, but we do have stockpiles managed by the Defense Logistics Agency. The real issue isn’t absence, it’s strategy: what to stockpile, how much, and under what assumptions.

Collins and Michot Foss argue for a more robust and better-targeted approach. That could mean aiming for 12 to 18 months worth of demand for both civilian and defense applications. Achieving that will require:

  • Smarter government purchasing and long-term contracts
  • Strategic deals with allies (e.g., swapping titanium for artillery shells with Ukraine)
  • Financing mechanisms to help companies hold critical inventory for emergency use

It’s not cheap, but it’s cheaper than scrambling mid-crisis when supplies are suddenly cut off.

The Case for Advanced Materials: Substitutes That Work Today

One powerful but often overlooked solution is advanced materials, which can reduce our dependence on vulnerable mineral supply chains altogether.

Take carbon nanotube (CNT) fibers, a cutting-edge material invented at Rice University. CNTs are lighter, stronger, and more conductive than copper. And unlike some future tech, this isn’t hypothetical: we could substitute CNTs for copper wire harnesses in electrical systems today.

As Michot Foss explained on the Energy Forum podcast:

“You can substitute copper and steel and aluminum with carbon nanotube fibers and help offset some of those trade-offs and get performance enhancements as well… If you take carbon nanotube fibers and you put those into a wire harness… you're going to be reducing the weight of that wire harness versus a metal wire harness like we already use. And you're going to be getting the same benefit in terms of electrical conductivity, but more strength to allow the vehicle, the application, the aircraft, to perform better.”

By accelerating R&D and deployment of CNTs and similar substitutes, we can reduce pressure on strained mineral supply chains, lower emissions, and open the door to more secure and sustainable manufacturing.

We Have Tools. We Need to Use Them.

The report offers a long list of solutions. Some are familiar, like tax incentives, public-private partnerships, and fast-tracked permits. Others draw on historical precedent, like “preclusive purchasing,” a WWII tactic where the U.S. bought up materials just so enemies couldn’t.

We also need to get creative:

  • Repurpose existing industrial sites into mineral hubs
  • Speed up R&D for substitutes and recycling
  • Buy out risky foreign-owned assets in friendlier countries

Permitting remains one of the biggest hurdles. In the U.S., it can take 7 to 10 years to approve a new critical minerals project, a timeline that doesn’t match the urgency of our strategic needs. As Collins said on the Energy Forum podcast:

“Time kills deals... That’s why it’s more attractive generally to do these projects elsewhere.”

That’s the reality we’re up against. Long approval windows discourage investment and drive developers to friendlier jurisdictions abroad. One encouraging step is the use of the Defense Production Act to fast-track permitting under national security grounds. That kind of shift, treating permitting as a strategic imperative, must become the norm, not the exception.

It’s Time to Redefine Sustainability

Sustainability has traditionally focused on cutting carbon emissions. That’s still crucial, but we need a broader definition. Today, energy and materials security are just as important.

Countries are now weighing cost and reliability alongside emissions goals. We're also seeing renewed attention to recycling, biodiversity, and supply chain resilience.

Net-zero by 2050 is still a target. But reality is forcing a more nuanced discussion:

  • What level of warming is politically and economically sustainable?
  • What tradeoffs are we willing to make to ensure energy access and affordability?

The bottom line: we can’t build a clean energy future without secure access to materials. Recycling helps, but it’s not enough. We'll need new mines, new tech, and a more flexible definition of sustainability.

My Take: We’re Running Out of Time

This isn’t just a policy debate. It’s a test of whether we’ve learned anything from the past few years of disruption. We’re not facing an open war, but the risks are real and growing.

We need to treat critical minerals like what they are: a strategic necessity. That means rebuilding stockpiles, reshoring processing, tightening alliances, and accelerating permitting across the board.

It won’t be easy. But if we wait until a real crisis hits, it’ll be too late.

Houston startup unveils sustainable bio-based leather at the rodeo

sustainable materials

Last month’s Houston Livestock Show and Rodeo stirred up another rootin’ tootin’ time for Houstonians and beyond.

But before the annual event galloped into the sunset, there were quite a few memorable innovations on display, with one notably coming from Rheom Materials.

The Houston-based pioneer of next-generation materials presented its scalable, bio-based alternative known as Shorai, a 93 percent bio-based leather, through two custom, western-inspired outfits that showed off cowboy flair through a sustainable lens.

“I'm a Houstonian, I love the rodeo,” Megan Beck, Rheom’s business development manager, recalls. “We're sitting there talking about it one day and we're like, ‘Okay, we've got to do something with this leather to show people how good it can look in apparel, how easy it is to wear.’”

Buoyed by the idea that their materials are meant to “change your impact, not your life,” Rheom captured the real-life energy of their bio-leather outfits under the rodeo’s neon lights in a short commercial video and photo shoot with models donning the samples, while dancing and enjoying the festivities. Rheom created a skirt, a leather jacket, and then a leather top for the look.

“Houston is such a vibrant city,” Beck says. “There's so much innovation here. I think the rodeo is just a really, really great example of that. And so we wanted to take this opportunity to take some of these garments out there and go on the slide, go on some of the rides, go into the wine garden and go dancing, because if you've ever felt some of the materials in the market in this space, they're very stiff, you can't really move in them, they're a little fragile, they kind of fall apart.”

Not only do the models in the video look fashionable, but they also look comfortable, and the leather looks natural and supple. And to the naked eye, Shorai appears to be like the leather most wearers are accustomed to.

“What we really wanted to showcase in this is the energy and the movement of the leather, and to show people how good it can look in apparel, and how easy it is to wear, which I think we were able to accomplish,” Beck says.

Next up, Beck says Rheom wants to scale production of Shorai, the Japanese word for “future,” at a competitive price point, while also reducing its carbon footprint by 80 percent when compared to synthetic leather. According to Beck, Rheom plans to see Shorai products come to market sometime this year.

“We have companies globally right now that are testing materials, that are prototyping, that are making garments, making handbags and footwear, and making eyewear because we have a plastic, as well,” Beck says. “So, this year, I do believe we'll start seeing those products actually come to market, which is very, very exciting for us.”

And with their large-scale production partner already set up for Shorai, Rheom plans to start its first production run of the product soon.

“In April, we'll actually be starting our first production run,” Beck says. “We'll be doing it at full scale, full width, and a full run of materials. So over the next five years, we're only going to just try to increase that capacity.”
