Being prepared: Has the Texas grid been adequately winterized?

Being Prepared

Houstonians may feel anxious as the city and state experience 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. 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.

Houston corporate communications expert on importance of messaging when scaling a tech company

HOUSTON INNOVATORS PODCAST EPISODE 207

Several years ago, Kelsey Hultberg decided to make a pivot. Looking for a role with career growth opportunities, the communications professional thought she'd find something at an oil and gas company, but then she met John Berger, founder and CEO of Sunnova, who was looking for someone to stand up their communications team amidst the solar energy company's growth.

"He hooked me," Hultberg shares on the Houston Innovators Podcast. "He said, 'I've got big plans for this company. I see where this energy industry is going, I see that we're prime for a transition, and I want to take this company public.' And I started a few weeks later."

Hultberg has been telling the story for Sunnova — which equips customers with solar and storage technology, providing them with energy independence — ever since, through scaling, new technologies, and its IPO in 2019.



Each phase of the company represented different challenges for Hultberg and her communications team. As she explains on the podcast, consistently conveying a strong message is key in any industry, but especially energy.

"Communication is critical," Hultberg says, "having a strategy and really being able to articulate who you are, what you stand for, what is your mission, what is your vision — and really beyond that, what is your strategy for how you move forward. ... You can never say the same thing to the same people too many times, especially when you're a company that some people have never heard of before."

And while there's a unique challenge to communications for energy transition companies, Hultberg says she views it as a huge opportunity as long as you have the right structure in place.

"Of course communications and being as strategic as possible with the story that you're telling and the narrative that you're weaving for your different audiences, but then you layer on an industry that's rapidly changing and is tumultuous at times," she says. "Being able to come back to the core mission and values is really incredible."

Hultberg says that when she originally joined the team in 2017, she thought a solar energy company in Houston was an interesting choice — and it was. Texas was not one of Sunnova's biggest markets at the time, Hultberg explains, but things are different now.

"Over the last couple of years, especially after Winter Storm Uri, where you saw a lot of people go without power. ... We had a lot of customers say, 'That can't happen again,'" she says. "You're seeing the adoption and uptick in solar in storage because they are looking for grid reliability and affordability and they aren't getting it from their utility providers."

New ERCOT dashboards let Houstonians check energy supply in real-time

power check

With winter temperatures and last year's freeze still top of mind for many Texans, the Electric Reliability Council of Texas, or ERCOT, has rolled out new dashboards to help you keep tabs on the energy supply in real-time.

Local may not have heard of ERCOT until the winter storm in February 2021 that would go on to take the lives of 246 people after the freeze overwhelmed the power grid and left millions freezing in the dark.

Since that storm, anxiety has been high. But these dashboards may help Texans get a gauge on what we're dealing with at any given moment.

The ERCOT site features find nine different dashboards on the Grid and Market Conditions page. Each dashboard has a timestamp of when it was last updated and if you select "Full View," you'll get a detailed explanation of what the graphs mean.

If things are normal, the grid will be green. But if it's black, that means we're in an energy emergency level 3, so expect controlled outages. Energy conservation would also be critical.

Opinion: Houston energy expert weighs in on if the state's power grid is ready for winter

guest column

The Winter Storm Uri, which struck Texas in February of 2021, was an unprecedented event in both severity and duration. At its most extreme, temperatures were as much as 40 to 50 degrees below their historic averages. The storm resulted in the largest controlled blackout in U.S. history, forcing the shedding of more than 23 gigawatts of load, the loss of power to 4.5 million homes and businesses for periods of one to four days, and the tragic loss of hundreds of lives.

A crisis of this magnitude has resulted in an intense re-examination of the Texas power grid. Not surprisingly, it has also resulted in record levels of finger-pointing and an ongoing search to identify the parties responsible. Among the casualties were all three Public Utility Commissioners that regulate the industry and a virtual purge of ERCOT, the organization that operates and manages the grid.

The Texas 87th Legislature filed an inordinate number of bills to address the electric system's failings, and Governor Abbott’s office has been vocal and actively working to ensure that there will never again be a repeat of the events of February 2021. The principal focus of the now reconstituted and expanded Public Utility Commission of Texas (PUCT) has been defining and implementing changes to system rules and operations in order to extract a greater degree of reliability from existing assets and incentivize the construction of significantly more MW of dispatchable generation. Many of the changes implemented by the PUCT will provide the market with a greater cushion against shocks to the system, moving the market away from a crisis management mode and towards a more proactive footing. We can expect even more change once current policies are assessed and more aggressive proposals are analyzed to determine whether they offer more benefit than harm to the market.

Amid all the debate, discussion, and wringing of hands, only one report has come close to identifying the smoking gun at the center of the crisis: the need for weatherization. The notion that weatherizing of generating assets is the key to future reliability has been discussed ad nauseum, but the report issued by the Federal Energy Regulatory Commission on November 16, 2021, attributes an equal share of the blame to the natural gas producing, processing, and transportation sector and its inability to perform reliably under the harsh conditions of Uri.

In the areas affected worst by the storm, gas production in Texas, Oklahoma, and Louisiana fell by more than 50 percent at its lowest point when compared to average production in the prior month. The Railroad Commission, not the Public Utility Commission, regulates natural gas transmission, and it was slow off the mark given the focus on generation. The Railroad Commission has now begun to implement weatherization requirements, with new initiatives slated to be in full effect for the winter of 2023.

It is imprudent to use “never” as a time scale, but I would place the probability at “remote” that Texas will see a recurrence of the events of February 2021 in 2022. In the unlikely event we did, the impacts would likely pale in comparison to those experienced last February. This is due both to the heightened state of preparedness with which the industry will approach the coming winter and the impact of changes put into effect by the PUCT as of January 1, 2022.

Governor Abbott has gone on record guaranteeing that the lights will stay on this winter, and I am inclined to agree. With the reinforcement of our fuel systems being mandated by the Railroad Commission, 2023 to 2025 should receive the same guarantee. Beyond that, as the demand for electricity in Texas continues to grow, we will need to rely on the initiatives under consideration by the PUCT to attract investment and innovation in new, dispatchable generation and flexible demand solutions to ensure long-term stability in the ERCOT market.

Report: Nearly 70 percent of Texans lost power during Winter Storm Uri, new UH report says

Uri by the numbers

Texans are painfully aware of the bitter loss caused by Winter Storm Uri; many are still coping with the after effects of the storm that set in on February 13.

But now, new figures reveal how ravaging the freeze was to the Lone Star State and its beleaguered residents.

At its peak, Uri left close to 4.5 million homes and businesses without power, killed more than 100 people, and caused an estimated $295 billion in damage. The storm is the single biggest insurance claim event in state history, as CultureMap previously reported.

More than two out of three Texans – some 69 percent – lost electricity at some point during the storm, for an average of 42 hours. Meanwhile, almost half – 49 percent – lost access to running water for an average of more than two days.

Additionally, nearly one-third of residents reported water damage in their home.

These numbers come from a just-released report by the Hobby School of Public Affairs at the University of Houston. According to UH, the Hobby School conducted the online survey of Texas residents 18 and older who live in the 213 counties served by the Texas Electrical Grid, which is managed by the Electric Reliability Council of Texas (ERCOT).

The full Hobby School report is available here.

Highlighting the frustrations millions have expressed since the storm has passed, nearly three out of four Texans – 74 percent – say they disapprove of ERCOT's performance during the winter storm — with 65 percent strongly disapproving. Some 78 percent of respondents claim they do not believe that the power outages in their area were carried out in an equitable manner.

Just how many Texans were okay with the council? Only 6 percent say they approve of ERCOT's widely criticized handling of the storm, per the survey. In the aftermath of the storm, seven ERCOT board members resigned following the near total failure of the state's power grid.

More than three-quarters of residents surveyed support policy reforms, which include requiring electricity generators to weatherize and boost their reserve capacity and natural gas companies to weatherize in order to be able to participate in the Texas market.

However, a majority of respondents oppose proposals that would require consumers to pay an additional fee in order to fund electricity generator weatherization efforts and to increase the amount of reserve electricity generation capacity, per the study.

The Hobby data produced other notable findings, including:

  • Some 61 percent of Texans prepared for the storm by buying additional food, 58 percent bought bottled water, and 55 percent filled their vehicle with gas. The next most common preparations were insulating pipes, covering or moving plants, and storing tap water.
  • A large number — 75 percent — reported difficulty obtaining food or groceries, 71 percent lost internet service, and 63 percent had difficulty obtaining bottled water.
  • When they lost electrical power and heat, 18 percent left their home, with 44 percent going to a local relative's home.
  • Of those who remained in their home without power, 26 percent used their gas oven or cooktop as a source of heat, 8 percent used a grill or smoker indoors, and 5 percent used an outdoor propane heater indoors.
  • Nearly half of Texans disapprove of Gov. Greg Abbott's performance during the winter storm, compared to 28 percent who approve.
  • More than half relied either a great deal, somewhat, or a little on three information sources before, during and after the storm hit: 68 percent on local TV news; 63 percent on neighbors and friends; and 55 percent on The Weather Channel.

The survey was fielded by YouGov from March 9 through March 19, with 1,500 YouGov respondents, resulting in a confidence interval of +/-2.5. Respondents were matched to a sampling frame on gender, age, ethnicity/race, and education, and are "representative of the adult population in these 213 Texas counties," per UH.

"Winter Storm Uri was a catastrophic weather event that impacted millions of lives across our state," said Kirk P. Watson, founding dean of the Hobby School, in a statement. "By digging deeper into its impact on Texans, we are learning critical information that will help inform future plans so a tragedy of this magnitude never happens again."

Expert says Houston is the prime spot for creating and testing game-changing resilience solutions

HOUSTON INNOVATORS PODCAST EPISODE 72

The city of Houston, along the rest of the Lone Star State, has been hit from every direction — pandemics, hurricanes, winter storms, and more.

"We're just whipsawed," says Richard Seline, co-founder at the Houston-based Resilience Innovation Hub Collaboratory. "We've gone from back-to-back storms and hurricanes to COVID to snow and ice and its impact on energy. People are just exhausted."

Now, Seline says on this week's episode of the Houston Innovators Podcast, this exhaustion is festering into frustration and anger — and calling for change. The things that need to change, Seline says, includes growing investment and innovation in resilience solutions.

"As a fourth generation Houstonian, it's just so hard to see my hometown get hit persistently with a lot of these weather and other type of disasters," Seline says.

These unprecedented disasters — which are of course occurring beyond Houston and Texas — have also sparked a growing interest in change for insurance companies that have lost a trillion dollars on the United States Gulf Coast over the past seven years, Seline says. Something has got to change regarding preparation and damage mitigation.

Creating conversations about change is exactly what Seline and the Resilience Innovation Hub, which is based out of The Cannon Tower in downtown Houston, is focused on. Following all these catastrophic events, the industry is overwhelmed with data — and now is the time to put it to use on innovation and tech solutions.

"We are drowning in data and hungry for intelligence — actionable intelligence," Seline says, adding that now innovators and entrepreneurs are taking on this data and creating solutions.

The challenge then becomes convincing decision makers to pivot from what they know and are comfortable with to what they don't know and what they aren't comfortable with.

And, Seline says on the show, that needs to happen across the board — from public and private companies to government entities and nonprofits both locally and beyond.

"I think that it's time to flip this on its head and say to the world, 'we got it.,'" Seline says. "Because we know these challenges, we are opening the world to the best ideas to be piloted and demonstrated. All I ask is that we get elective and appointed officials who are open to ideas and solutions. That's how innovation occurs."

Houston poised to add 30,900 new jobs in 2026, forecast says

jobs forecast

Buoyed by the growing health care sector, the Houston metro area will add 30,900 jobs in 2026, according to a new forecast from the Greater Houston Partnership.

The report predicts the Houston area’s health care sector will tack on 14,000 jobs next year, which would make it the No. 1 industry for local job growth. The 14,000 health care jobs would represent 45 percent of the projected 30,900 new jobs. In the job-creation column, the health care industry is followed by:

  • Construction: addition of 6,100 jobs in 2026
  • Public education: Addition of 5,800 jobs
  • Public administration: Addition of 5,000 jobs

At the opposite end of the regional workforce, the administrative support services sector is expected to lose 7,500 jobs in 2026, preceded by:

  • Manufacturing: Loss of 3,400 jobs
  • Oil-and-gas extraction: Loss of 3,200 jobs
  • Retail: Loss of 1,800 jobs

“While current employment growth has moderated, the outlook remains robust and Houston’s broader economic foundation remains strong,” GHP president and CEO Steve Kean said in the report.

“Global companies are choosing to invest in Houston — Eli Lilly, Foxconn, Inventec, and others — because they believe in our workforce and our long-term trajectory,” Kean added. “These commitments reinforce that Houston is a place where companies can scale and where our economy continues to demonstrate its resilience as a major engine for growth and opportunity. These commitments and current prospects we are working on give us confidence in the future growth of our economy.”

The Greater Houston Partnership says that while the 30,900-job forecast falls short of the region’s recent average of roughly 50,000 new jobs per year, it’s “broadly in line with the muted national outlook” for employment gains anticipated in 2026.

“Even so, Houston’s young, skilled workforce and strong pipeline of major new projects should help offset energy sector pressures and keep regional growth on pace with the nation,” the report adds.

The report says that even though the health care sector faces rising insurance costs, which might cause some people to delay or skip medical appointments, and federal changes in Medicare and Medicaid, strong demographic trends in the region will ensure health care remains “a key pillar of Houston’s economy.”

As for the local oil-and-gas extraction industry, the report says fluctuations and uncertainty in the global oil-and-gas market will weigh on the Houston sector in 2026. Furthermore, oil-and-gas layoffs partly “reflect a longer-term trend as companies in the sector move toward greater efficiency using fewer workers to produce similar volumes,” according to the report.

Construction underway on first-of-its-kind 3D-printed community in Houston

Building a Sustainable Future

Houston is putting itself front-and-center to help make sustainable, affordable housing a reality for 80 homeowners in an innovative scalable housing community. Developer Cole Klein Builders has partnered with HiveASMBLD to pioneer what’s touted as the world’s first large-scale, one-of-a-kind, affordable housing development using 3D printing technology — merging robotics, design, and sustainability.

Located across from Sterling Aviation High School, near Hobby Airport, Zuri Gardens will offer 80 two-bedroom, two-bathroom homes of approximately 1,360 square feet, situated in a park-like setting that includes walking trails and a community green space.

Homes in Zuri Gardens will hit the market in early summer of 2026. Final pricing has yet to be determined, but Cole Klein Builders expects it to be in the mid-to-high 200s.

Interestingly, none of the homes will offer garages or driveways, which the developer says will provide a cost savings of $25,000-$40,000 per home. Instead of parking for individual units, 140 parking spaces will be provided.

Each two-story home is comprised of a ground floor printed by HiveASMBLD, using a proprietary low-carbon cement alternative by Eco Material Technologies that promises to enhance strength and reduce CO2 emissions. The hybrid homes will have a second floor built using engineered wood building products by LP Building Solutions. Overall, the homes are designed to be flood, fire, and possibly even tornado-proof.

The "Zuri" in Zuri Gardens is the Swahili word for “beautiful,” a choice that is fitting considering that the parks department will be introducing a five acre park to the project — with 3D-printed pavilions and benches — plus, a three-acre farm is located right across the street. The Garver Heights area is classified as a food desert, which means that access to fresh food is limited. Residents will have access to the farm’s fresh produce, plus opportunities to participate in gardening and nutrition workshops.

Cole Klein Builders created Zuri Gardens in partnership with the Houston Housing Community Development Department, who provided infrastructure reimbursements for the roads, sewer lines, and water lines. In return, CKB agreed to push the purchase prices for the homes as low as possible.

Zuri Gardens also received $1.8 million dollars from the Uptown Tourism Bond, 34 percent of which must be used with minority-owned small businesses. Qualified buyers must fit a certain area of median income according to HUD guidelines, and homes must be owner-occupied at all times. Zuri Gardens already has an 800-person waitlist.

“They’re trying to bridge that gap to make sure there is a community for the homebuyers who need it — educators, law enforcement, civil workers, etc.,” Cole Klein Builders’ co-principal Vanessa Cole says. “You have to go through a certification process with the housing department to make sure that your income is in alignment for this community. It has been great, and everyone has been really receptive.”

Cole has also brought insurance underwriters to visit the site and to help drive premiums below regular rates for Houston homeowners, as claim risks for one of the 3D homes are extremely low.

Tim Lankau, principal at HiveASMBLD, notes that the 3D hybrid design allows for a more traditional appearance, while having the benefits of a concrete structure: “That’s where the floodwaters would go, that’s where you can hide when there’s a tornado, and that’s where termites would eat. So you get the advantages of it while having a traditionally-framed second floor.”

It’s important to note that Zuri Gardens is not located in a flood prone area, nor did it flood during Hurricane Harvey — being flood-proof is merely a perk of a cement house. The concrete that Eco Material Technologies developed is impervious. The walls are printed into hollow forms, which house rebar, plumbing, and accessible conduits for things like electrical lines and smart house features. Those walls are then filled with a foamcrete product that expands to form a “monolithic concrete wall.”

David McNitt, of Eco Material Technologies, explains that his proprietary concrete is made of PCV, and contains zero Portland cement. Instead, McNitt’s cement is made from coal ash and is 99 percent green (there are a few chemicals added to the ash). Regardless, it’s made from 100 percent waste products.

“This is a product that has really been landfilled before,” says McNitt. “It’s coal ash, and it’ll set within 8-10 minutes. It’s all monolithic, and one continuous pour — it’s literally all one piece.”

Eco Material Technologies’ concrete product is impressively durable. A traditional cinderblock wall will crush at around 800 psi, while this material crushes at about 8,000 psi.

“It’s ten times stronger than a cinderblock wall that can withstand hurricanes,” claims McNitt. “I don’t think you’d even notice a hurricane. It’ll be really quiet inside, too — so you won’t get interrupted during your hurricane party. It’s way over-engineered, it really is.”

The second story is built using weatherproof and eco-friendly products by LP Building Solutions. Their treated, engineered wood products come with a 50 year warranty, and their radiant barrier roof decking product blocks 97% of UV rays, and keeps attic temperatures 30° cooler than traditional building materials. These materials, combined with the concrete first floor, will keep heating and cooling costs low — something the folks at HiveASMBLD refer to as “thermal mass performance.”

UH receives $2.6M gift to support opioid addiction research and treatment

drug research

The estate of Dr. William A. Gibson has granted the University of Houston a $2.6 million gift to support and expand its opioid addiction research, including the development of a fentanyl vaccine that could block the drug's ability to enter the brain.

The gift builds upon a previous donation from the Gibson estate that honored the scientist’s late son Michael, who died from drug addiction in 2019. The original donation established the Michael C. Gibson Addiction Research Program in UH's department of psychology. The latest donation will establish the Michael Conner Gibson Endowed Professorship in Psychology and the Michael Conner Gibson Research Endowment in the College of Liberal Arts and Social Sciences.

“This incredibly generous gift will accelerate UH’s addiction research program and advance new approaches to treatment,” Daniel O’Connor, dean of the College of Liberal Arts and Social Sciences, said in a news release.

The Michael C. Gibson Addiction Research Program is led by UH professor of psychology Therese Kosten and Colin Haile, a founding member of the UH Drug Discovery Institute. Currently, the program produces high-profile drug research, including the fentanyl vaccine.

According to UH, the vaccine can eliminate the drug’s “high” and could have major implications for the nation’s opioid epidemic, as research reveals Opioid Use Disorder (OUD) is treatable.

The endowed professorship is combined with a one-to-one match from the Aspire Fund Challenge, a $50 million grant program established in 2019 by an anonymous donor. UH says the program has helped the university increase its number of endowed chairs and professorships, including this new position in the department of psychology.

“Our future discoveries will forever honor the memory of Michael Conner Gibson and the Gibson family,” O’Connor added in the release. “And I expect that the work supported by these endowments will eventually save many thousands of lives.”
