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 startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”

Houston business mogul Tilman Fertitta acquires Caesars in $17.6B deal

Money Moves

Houston billionaire Tilman Fertitta may currently be serving as America’s ambassador to Italy, but his company is as busy as ever. Fresh off its move to revive the Houston Comets WNBA franchise, his company, Fertitta Entertainment, has announced a $17.6 billion deal to acquire Caesars Entertainment, Inc.

Speculation about the deal has been circulating since at least March, according to various media reports. The deal combines Fertitta’s well-known Golden Nugget casino brand with all of the properties in the Caesars’ portfolio, including Las Vegas hotels Caesars Palace, Harrah's, Paris Las Vegas, Planet Hollywood, Horseshoe, The LINQ Hotel, Flamingo, and The Cromwell.

Overall, the combined company will include 60 domestic casino resorts and gaming facilities; online gaming including sports betting, iCasino, and Caesar’s online poker platform; retail sports betting at over 200 third-party locations through the William Hill brand; and over 550 Fertitta Entertainment outlets, including more than 450 Landry's full-service restaurants across America. The companies will combine their loyalty programs, Caesars Rewards, Golden Nugget's 24 Karat Select Club, and Landry's Select Club.

The terms will see Caesars’ shareholders receive $31 per share. Fertitta Entertainment will also acquire approximately $11.9 billion of Caesars' outstanding debt.

The transaction will be financed through a combination of equity contributed by Fertitta Entertainment, assumed Caesars' debt, and new committed debt financing arranged by a group consisting of 10 banks. It is subject to approval by Caesars’ shareholders and government regulators.

Fertitta Entertainment is the Houston-based company behind a diverse array of hospitality businesses, including The Golden Nugget, The Post Oak Hotel, River Oaks District, the Kemah Boardwalk, and Houston’s Downtown Aquarium.

It also operates a number of prominent restaurant brands, including Mastro's Restaurants, Del Frisco's Double Eagle Steakhouse, Morton's The Steakhouse, The Palm, McCormick & Schmick's, Landry's Seafood House, The Oceanaire Seafood Room, and Saltgrass Steak House.

4 Houston-area institutions get $8M for cancer research facilities

fighting cancer

Cancer research capabilities in the Houston area just got an $8 million boost.

On Wednesday, May 20, the Cancer Prevention and Research Institute of Texas (CPRIT) awarded $8 million in grants to institutions in Houston and Bryan for the creation or expansion of so-called “core” cancer research facilities.

“Core facilities provide shared access to advanced technology, equipment, and scientific expertise that may not be available at every institution,” CPRIT says. “These core facilities are vital to not only cancer research but also to the study of diseases beyond cancer.”

Houston-area recipients of these $2 million grants are:

  • A facility at the University of Texas Health Science Center for preclinical support of cancer researchers in Texas to evaluate new safe, effective drugs and drug combinations.
  • The Accelerator for Cancer Therapeutics, operated by Houston’s Texas Medical Center Foundation. The accelerator helps researchers and startups move innovative cancer treatments from the lab to clinical trials.
  • Rice University’s Genetic Design & Engineering Center in Houston. The center enables researchers to collaborate on studies of custom DNA for cancer treatment.
  • A facility at the Texas A&M University System’s Health Science Center in Bryan that aims to speed up the development of cancer therapies.

In addition to those grants, the University of Texas M.D. Anderson Cancer Center, Methodist Hospital Research Institute, Baylor College of Medicine, and Rice University shared $21 million to recruit cancer researchers from other institutions.

The largest of those grants—totalling $4 million—went to M.D. Anderson for the recruitment of renowned cancer researcher Andre Nussenzweig from the National Institutes of Health. His research focuses on how DNA damage and faulty DNA repairs lead to cancer.

Here are the totals for the other CPRIT grants awarded in the Houston area:

  • $12.8 million to Houston-based Indapta Therapeutics for the development of an off-the-shelf therapy that naturally kills cancer cells, combined with an immunity-targeting agent for a type of leukemia.
  • $11.1 million to MD Anderson, including $5 million for a statewide platform to improve long-term health outcomes in adolescents and young adults who survived cancer.
  • $8.4 million to Baylor College of Medicine, including $4.8 million for two training programs for cancer researchers.
  • $6.25 million to UT Health Houston, including $4 million for a biomedical informatics and genomics training program for cancer researchers.
  • $4.4 million to the Texas A&M Health Science Center’s Houston campus, including $2.4 million for a cancer therapeutics training program.
  • $2.75 million to Rice, including $250,000 for a study of ovarian cancer.
  • $2 million to Houston-based March Biosciences for the development of a targeted therapy for treating T-cell lymphoma.
  • $1.15 million to the University of Houston, including $900,000 for a platform for detection of lung cancer.
  • $900,000 to Texas A&M in Bryan to conduct clinical drug trials in rural and underserved communities around the state.
  • $800,000 to Houston- and Israel-based Xerient Pharma for the development of an oral form of a cell-protecting drug called amifostine to protect the upper GI tract from radiation damage during pancreatic cancer treatment.
  • $659,000 to Missouri City-based OmniNano Pharmaceuticals for the development of a two-drug combination to treat the most common form of pancreatic cancer.
  • $250,000 to the University of Texas Medical Branch at Galveston for a novel therapeutic to prevent colitis-related colorectal cancer.
