2025 marked a pivotal year for Texas’ energy ecosystem. Rising demand, accelerating renewable integration, tightening reserve margins and growing industrial load reshaped the way policymakers, utilities and the broader market think about reliability.

This wasn’t just another year of operational challenges; it was a clear signal that the state is entering an era where growth and innovation must move together in unison if Texas is going to keep pace.

What happened in 2025 is already influencing the decisions utilities, regulators and large energy consumers will make in 2026 and beyond. If Texas is going to remain the nation’s proving ground for large-scale energy innovation, this year made one thing clear: we need every tool working together and working smarter.

What changed: Grid, policy & the growth of renewables

This year, ERCOT recorded one of the steepest demand increases in its history. From January through September 2025, electricity consumption reached 372 terawatt-hours (TWh), a 5 percent increase over the previous year and a 23 percent jump since 2021. That growth officially positions ERCOT as the fastest-expanding large grid in the country.

To meet this rising load, Texas leaned heavily on clean energy. Solar, wind and battery storage served approximately 36 percent of ERCOT’s electricity needs over the first nine months of the year, a milestone that showcased how quickly Texas has diversified its generation mix. Utility-scale solar surged to 45 TWh, up 50 percent year-over-year, while wind generation reached 87 TWh, a 36 percent increase since 2021.

Battery storage also proved its value. What was once niche is now essential: storage helped shift mid-day excess solar to evening peaks, especially during a historic week in early spring when Texas hit new highs for simultaneous wind, solar and battery output.

Still, natural gas remained the backbone of reliability. Dispatchable thermal resources supplied more than 50 percent of ERCOT’s power 92 percent of the time in Q3 2025. That dual structure of fast-growing renewables backed by firm gas generation is now the defining characteristic of Texas’s energy identity.

But growth cuts both ways. Intermittent generation is up, yet demand is rising faster. Storage is scaling, but not quite at the rate required to fill the evening reliability gap. And while new clean-energy projects are coming online rapidly, the reality of rising population, data center growth, electrification and heavy industrial expansion continues to outpace the additions.

A recent forecast from the Texas Legislative Study Group projects demand could climb another 14 percent by mid-2026, tightening reserve margins unless meaningful additions in capacity, or smarter systemwide usage, arrive soon.

What 2025 meant for the energy ecosystem

The challenges of 2025 pushed Texas to rethink reliability as a shared responsibility between grid operators, generation companies, large load customers, policymakers and consumers. The year underscored several realities:

1. The grid is becoming increasingly weather-dependent. Solar thrives in summer; wind dominates in spring and winter. But extreme heat waves and cold snaps also push demand to unprecedented levels. Reliability now hinges on planning for volatility, not just averages.

2. Infrastructure is straining under rapid load growth. The grid handled multiple stress events in 2025, but it required decisive coordination and emerging technologies, such as storage methods, to do so.

3. Innovation is no longer optional. Advanced forecasting, grid-scale batteries, demand flexibility tools, and hybrid renewable-gas portfolios are now essential components of grid stability.

4. Data centers and industrial electrification are changing the game. Large flexible loads present both a challenge and an opportunity. With proper coordination, they can help stabilize the grid. Without it, they can exacerbate conditions of scarcity.

Texas can meet these challenges, but only with intentional leadership and strong public-private collaboration.

The system-level wins of 2025

Despite volatility, 2025 showcased meaningful progress:

Renewables proved their reliability role. Hitting 36 percent of ERCOT’s generation mix for three consecutive quarters demonstrates that wind, solar and batteries are no longer supplemental — they’re foundational.

Storage emerged as a real asset for reliability. Battery deployments doubled their discharge records in early 2025, showing the potential of short-duration storage during peak periods.

The dual model works when balanced wisely. Natural gas continues to provide firm reliability during low-renewable hours. When paired with renewable growth, Texas gains resilience without sacrificing affordability.

Energy literacy increased across the ecosystem. Communities, utilities and even industrial facilities are paying closer attention to how loads, pricing signals, weather and grid conditions interact—a necessary cultural shift in a fast-changing market.

Where Texas goes in 2026

Texas heads into 2026 with several unmistakable trends shaping the road ahead. Rate adjustments will continue as utilities like CenterPoint request cost recovery to strengthen infrastructure, modernize outdated equipment and add the capacity needed to handle record-breaking growth in load.

At the same time, weather-driven demand is expected to stay unpredictable. While summer peaks will almost certainly set new records, winter is quickly becoming the bigger wild card, especially as natural gas prices and heating demand increasingly drive both reliability planning and consumer stress.

Alongside these pressures, distributed energy is set for real expansion. Rooftop solar, community battery systems and hybrid generation-storage setups are no longer niche upgrades; they’re quickly becoming meaningful grid assets that help support reliability at scale.

And underlying all of this is a cultural shift toward energy literacy. The utilities, regulators, businesses, and institutions that understand load flexibility, pricing signals and efficiency strategies will be the ones best positioned to manage costs and strengthen the grid. In a market that’s evolving this fast, knowing how we use energy matters just as much as knowing how much.

The big picture: 2025 as a blueprint for a resilient future

If 2025 showed us anything, it’s that Texas can scale innovation at a pace few states can match. We saw record renewable output, historic storage milestones and strong thermal performance during strain events. The Texas grid endured significant stress but maintained operational integrity.

But it also showed that reliability isn’t a static achievement; it’s a moving target. As population growth, AI and industrial electrification and weather extremes intensify, Texas must evolve from a reactive posture to a proactive one.

The encouraging part is that Texas has the tools, the talent and the market structure to build one of the most resilient and future-ready power ecosystems in the world. The test ahead isn’t whether we can generate enough power; it’s whether we can coordinate systems, technologies and market behavior fast enough to meet the moment.

And in 2026, that coordination is precisely where the opportunity lies.

Texas data center boom could strain water supply, new report warns

thirst for data

As data centers continue to boom throughout Texas, a new report from the Houston Advanced Research Center (HARC) warns that the trend could strain the state’s water supply.

HARC estimates Texas data centers used 25 billion gallons of water in 2025—and that the demand for water will continue to rise to meet the needs of the 464 data centers currently in Texas, as well as 70 additional sites currently under development.

In the report, titled “Thirsty Data and the Lone Star State: The Impact of Data Center Growth on Texas’ Water Supply,” The Woodlands-based nonprofit says that water use for cooling data centers is expected to double or triple by 2028 on the national level. If projections hold, the total annual water use for data centers in Texas will increase by 0.5 percent to 2.7 percent by 2030, or to between 29 billion and 161 billion gallons of water consumed.

Data centers often use water for cooling, though water demand is dependent on the type of cooling used, the size and type of the data center. Although used water can be reused, some new water withdrawals are always needed to replace evaporated water and other systems’ water losses. Water is also used to cool the power plants that generate electricity used by the data centers.

The HARC report offers guidance to address the overall concerns of water demands by data centers, including:

  • Dry cooling methods
  • Increased reliance on wind and solar energy sources
  • Alternative water supplies, like treated wastewater or brackish water for cooling
  • Adjusted operating schedules to accommodate water usage
  • Partnering with local companies to develop projects that reduce water leaks
  • Companies creating their own water infrastructure investments

The report goes on to explain that the Texas State Water Plan, produced by the Texas Water Development Board, projects shortages of 1.6 trillion gallons by 2030 and 2.3 trillion gallons by 2070. HARC posits that the recent surge in water demand from AI data centers is not fully reflected in those projections.

"Texas water plans always look backward, not forward," the report reads. "That means the 2027 water plan, which is in development now, will be based on 2026 regional water plans that do not include forecasted data center water use. Data centers that began operation in 2025 will not be added to the State Water Plan until 2032."

Currently, there are no state regulations that require data centers to report how much water they use. However, the Public Utility Commission of Texas (PUC) plans to survey operators of data centers and cryptocurrency mining facilities on their water consumption, cooling methods and electricity sources this spring. It is expected to release the results by the end of the year. The companies will have six weeks to respond. The Texas Water Development Board will assist the PUCT on the questions.

“I think we all recognize the importance of data centers and the technology they support and what they give to our modern-day life,” PUC Commissioner Courtney Hjaltman said during the last commission meeting. “Texans, regulators and the legislature really need that understanding of data centers, really need to understand the water they’re using so that we can plan and create the Texas we want.”

Houston cleantech startup seeks $200M for superhot geothermal plant

seeing green

Houston-based Quaise Energy is looking to raise $200 million to support the development of a 50-megawatt superhot geothermal plant in Oregon.

The company is seeking $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance, a representative from the company tells Energy Capital. Axios first reported the news late last month.

Quaise specializes in terawatt-scale geothermal power. It is known for its millimeter-wave drilling technology, which was developed at MIT.

The company's Project Obsidian development in central Oregon will combine conventional drilling with its millimeter-wave technology. Quaise says the project, targeted to come online in 2030, could be the first commercial plant to operate in superhot rock, a more efficient and abundant resource, but one that requires more advanced and durable drilling technology.

Quaise says Obsidian would initially generate 50 megawatts of "always-on" power and would be designed to add 200 megawatts as additional wells are developed. A power-purchase deal has already been signed for the initial 50 megawatts with an undisclosed customer.

A representative from the company says Quaise would also use the funding to continue advancing its millimeter-wave technology and prepare it for commercialization.

Last year, the company drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas.

“Our progress this year has exceeded all expectations,” Carlos Araque, CEO and president of Quaise Energy, said at the time. “We’re drilling faster and deeper at this point than anyone believed possible, proving that millimeter-wave technology is the only tool capable of reaching the superhot rock needed for next-generation geothermal power. We are opening up a path to a new energy frontier.”

Canary Media reports that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027.

Quaise raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022. Major investors include Prelude Ventures, Safar Partners, Mitsubishi Corporation, Nabors Industries, TechEnergy and others.

Quaise was one of eight Houston-area companies to appear on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025.

Houston positioned to lead in Carbon Capture Utilization (CCU), study shows

The View From HETI

With global demand for energy production while lowering emissions continues to grow, Houston and the Gulf Coast region are uniquely positioned to lead with carbon capture, utilization and sequestration (CCUS). A new study developed by the Houston Energy Transition Initiative (HETI) in collaboration with Deloitte Consulting explores how the region can transform captured CO₂ into valuable products while supporting continued economic growth and industrial competitiveness.

Key takeaways from the report include:

Houston and the Gulf Coast are uniquely advantaged to utilize and store carbon.As a global hub for chemicals and refining industries, Houston has access to world-class infrastructure, a skilled workforce, and access to global markets. The region also has one of the nation’s highest concentrations of industrial CO2 and creates the opportunity to capture waste material streams to deliver lower carbon intensity products that continue to deliver economic benefits to the region.

While carbon capture and sequestration (CCS) projects continue to advance, CCU requires coordinated action across policy, infrastructure, technology and market demand to scale successfully. Utilization and sequestration are complementary strategies that support and protect investment deployments. CCS acts as an early foundation while markets and infrastructure evolve toward broader CO₂ utilization, and CCU is essential to developing low-carbon-intensity value chains and products.

“Our collaboration with Deloitte highlights how Houston and the Gulf Coast continue to build on the strengths that have long made our region an energy leader. Houston’s infrastructure, workforce, and industrial ecosystem uniquely position the region to scale CCU,” said Jane Stricker, Senior Vice President, Energy Transition, and Executive Director of HETI. “With supportive policy, continued innovation, and strong industry partnerships, we can accelerate CCU deployment, create new low-carbon value chains, and ensure Houston remains at the forefront of the global energy transition.”
