The Electric Reliability Council of Texas, which manages about 90 percent of the state’s power, is waving a warning flag: The ERCOT grid may set a new record for peak demand this summer.

Based on expectations for a hotter summer this year than last year, ERCOT predicts power demand will hit a peak of more than 92.2 gigawatts this summer — enough power for roughly 18.4 million homes.

“Given the potential for extreme heat combined with significant load growth, ERCOT may surpass its current all-time summer peak,” the organization says in its 2026 summertime forecast.

Further taxing the ERCOT grid are power-hungry data centers and cryptocurrency-mining facilities.

Last year’s peak summer demand for ERCOT reached 83.7 megawatts on Aug. 18, and all-time peak demand of 85.5 gigawatts was recorded on Aug. 10, 2023.

Fortunately, ERCOT believes the grid is in good shape to withstand this summer’s heat: It found a 0.09 percent chance of a grid emergency in June and a 0.21 percent chance in July.

More generation of electricity from solar and wind is helping ERCOT meet stepped-up demand prompted by population growth, and the significant power needs of data centers and cryptocurrency-mining facilities.

About 27 million Texas customers depend on power from ERCOT’s grid.

power deal

Spring-based private equity firm Arroyo Investors has teamed up with ONCEnergy, a Portland, Oregon-based developer of clean energy projects, to buy a 60-megawatt wind farm southeast of Amarillo.

Skyline Renewables, which acquired the site, known as the Whirlwind Energy Center, in 2018, was the seller. The purchase price wasn’t disclosed.

Whirlwind Energy Center, located in Floyd County, West Texas, comprises 26 utility-scale wind turbines. The wind farm, built in 2007, supplies power to Austin Energy.

“The acquisition reflects our focus on value-driven investments with strong counterparties, a solid operating track record, and clear relevance to markets with growing capacity needs,” Brandon Wax, a partner at Arroyo, said in a press release. “Partnering with ONCEnergy allows us to leverage deep operational expertise while expanding our investment footprint in the market.”

Arroyo focuses on energy infrastructure investments in the Americas. Its portfolio includes Spring-based Seaside LNG, which produces liquefied natural gas and LNG transportation services.

Last year, Arroyo closed an investment fund with more than $1 billion in total equity commitments.

Since its launch in 2003, Arroyo has “remained committed to investing in high-quality assets, creating value and positioning assets for exit within our expected hold period,” founding partner Chuck Jordan said in 2022.

Renewables to play greater role in powering data centers, JLL says

Data analysis

Renewable energy is evolving as the primary energy source for large data centers, according to a new report.

The 2026 Global Data Center Outlook from commercial real estate services giant JLL points out that the pivot toward big data centers being powered by renewable energy stems from rising electricity costs and tightening carbon reduction requirements. In the data center sector, renewable energy, such as solar and wind power, is expected to outcompete fossil fuels on cost, the report says.

The JLL forecast carries implications for the Houston area’s tech and renewable energy sectors.

As of December, Texas was home to 413 data centers, second only to Virginia at 665, according to Visual Capitalist. Dozens more data centers are in the pipeline, with many of the new facilities slated for the Houston, Austin, Dallas-Fort Worth and San Antonio areas.

Amid Texas’ data center boom, several Houston companies are making inroads in the renewable energy market for data centers. For example, Houston-based low-carbon energy supplier ENGIE North America agreed last May to supply up to 300 megawatts of wind power for a Cipher Mining data center in West Texas.

The JLL report says power, not location or cost, will become the primary factor in selecting sites for data centers due to multi-year waits for grid connections.

“Energy infrastructure has emerged as the critical bottleneck constraining expansion [of data centers],” the report says. “Grid limitations now threaten to curtail growth trajectories, making behind-the-meter generation and integrated battery storage solutions essential pathways for sustainable scaling.”

Behind-the-meter generation refers to onsite energy systems such as microgrids, solar panels and solar battery storage. The report predicts global solar capacity will expand by roughly 100 gigawatts between 2026 and 2030 to more than 10,000 gigawatts.

“Solar will account for nearly half of global renewable energy capacity in 2026, and despite its intermittent properties, solar will remain a key source of sustainable energy for the data center sector for years to come,” the report says.

Thanks to cost and sustainability benefits, solar-plus-storage will become a key element of energy strategies for data centers by 2030, according to the report.

“While some of this energy harvesting will be colocated with data center facilities, much of the energy infrastructure will be installed offsite,” the report says.

Other findings of the report include:

  • AI could represent half of data center workloads by 2030, up from a quarter in 2025.
  • The current five-year “supercycle” of data center infrastructure development may result in global investments of up to $3 trillion by 2030.
  • Nearly 100 gigawatts worth of new data centers will be added between 2026 and 2030, doubling global capacity.

“We’re witnessing the most significant transformation in data center infrastructure since the original cloud migration,” says Matt Landek, who leads JLL’s data center division. “The sheer scale of demand is extraordinary.”

Hyperscalers, which operate massive data centers, are allocating $1 trillion for data center spending between 2024 and 2026, Landek notes, “while supply constraints and four-year grid connection delays are creating a perfect storm that’s fundamentally reshaping how we approach development, energy sourcing, and market strategy.”

Since 2023, wind and solar power have been the fastest-growing sources of electricity for the Electric Reliability Council of Texas (ERCOT) and increasingly are meeting stepped-up demand, according to a new report from the U.S. Energy Information Administration (EIA).

The report says utility-scale solar generated 50 percent more electricity for ERCOT in the first nine months this year compared with the same period in 2024. Meanwhile, electricity generated by wind power rose 4 percent in the first nine months of this year versus the same period in 2024.

Together, wind and solar supplied 36 percent of ERCOT’s electricity in the first nine months of 2025.

Heavier reliance on wind and solar power comes amid greater demand for ERCOT electricity. In the first nine months of 2025, ERCOT recorded the fastest growth in electricity demand (5 percent) among U.S. power grids compared with the same period last year, according to the report.

“ERCOT’s electricity demand is forecast to grow faster than that of any other grid operator in the United States through at least 2026,” the report says.

EIA forecasts demand for ERCOT electricity will climb 14 percent in the first nine months of 2026 compared with the same period this year. This anticipated jump coincides with a number of large data centers and cryptocurrency mining facilities coming online next year.

The ERCOT grid covers about 90 percent of Texas’ electrical load.

UH researchers make breakthrough in cutting carbon capture costs

Carbon breakthrough

A team of researchers at the University of Houston has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

Led by Professor Mim Rahimi at UH’s Cullen College of Engineering, the team released two significant publications that made significant strides relating to carbon capture processes. The first, published in Nature Communications, introduced a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. Another, featured on the cover of ES&T Engineering, demonstrated a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“These publications reflect our group’s commitment to fundamental electrochemical innovation and real-world applicability,” Rahimi said in a news release. “From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy.”

According to the researchers, the “A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture” research paper marked the beginning of the team’s first focus. The research examined the replacement of costly ion-exchange membranes with gas diffusion electrodes. They found that the membranes were the most expensive part of the system, and they were also a major cause of performance issues and high maintenance costs.

The researchers achieved more than 90 percent CO2 removal (nearly 50 percent more than traditional approaches) by engineering the gas diffusion electrodes. According to PhD student and co-author of the paper Ahmad Hassan, the capture costs approximately $70 per metric ton of CO2, which is competitive with other innovative scrubbing techniques.

“By removing the membrane and the associated hardware, we’ve streamlined the EMAR workflow and dramatically cut energy use,” Hassan said in the news release. “This opens the door to retrofitting existing industrial exhaust systems with a compact, low-cost carbon capture module.”

The second breakthrough, published by PhD student Mohsen Afshari, displayed a reversible flow battery architecture that absorbs CO2 during charging and releases it upon discharge. The results suggested that the technology could potentially provide carbon removal and grid balancing when used with intermittent renewables, such as solar or wind power.

“Integrating carbon capture directly into a redox flow battery lets us tackle two challenges in one device,” Afshari said in the release. “Our front-cover feature highlights its potential to smooth out renewable generation while sequestering CO2.”

energy forecast

Texas is expected to see a 77-gigawatt decrease in power generation capacity within the next 10 years under the federal "One Big Beautiful Bill Act," which President Trump recently signed into law, a new forecast shows.

Primarily due to the act’s repeal of some clean energy tax credits, a forecast, published by energy policy research organization Energy Innovation Policy & Technology, predicts that Texas is expected to experience a:

  • 54-gigawatt decline in capacity from solar power by 2035
  • 23-gigawatt decline in capacity from wind power by 2035
  • 3.1-gigawatt decline in capacity from battery-stored power by 2035
  • 2.5-gigawatt increase in capacity from natural gas by 2035

The legislation “will reduce additions of new, cost-effective electricity capacity in Texas, raising power prices for consumers and decreasing the state’s GDP and job growth in the coming years,” the forecast says.

The forecast also reports that the loss of sources of low-cost renewable energy and the resulting hike in natural gas prices could bump up electric bills in Texas. The forecast envisions a 23 percent to 54 percent hike in electric rates for residential, commercial and industrial customers in Texas.

Household energy bills are expected to increase by $220 per year by 2030 and by $480 per year by 2035, according to the forecast.

Energy Innovation Policy & Technology expects job growth and economic growth to also take a hit under the "Big Beautiful Bill."

The nonprofit organization foresees annual losses of $5.9 billion in Texas economic output (as measured by GDP) by 2030 and $10 billion by 2035. In tandem with the impact on GDP, Texas is projected to lose 42,000 jobs by 2030 and 94,000 jobs by 2035 due to the law’s provisions, according to the organization.

The White House believes the "Big Beautiful Bill" will promote, not harm, U.S. energy production. The law encourages the growth of traditional sources of power such as oil, natural gas, coal and hydropower.

“The One Big Beautiful Bill Act is a historic piece of legislation that will restore energy independence and make life more affordable for American families by reversing disastrous Biden-era policies that constricted domestic energy production,” Interior Secretary Doug Burgum said in a news release.

Promoters of renewable energy offer an opposing viewpoint.

“The bill makes steep cuts to solar energy and places new restrictions on energy tax credits that will slow the deployment of residential and utility-scale solar while undermining the growth of U.S. manufacturing,” says the Solar Energy Industries Association.

Jason Grumet, CEO of the American Clean Power Association, complained that the legislation limits energy production, boosts prices for U.S. businesses and families, and jeopardizes the reliability of the country’s power grid.

“Our economic and national security requires that we support all forms of American energy,” Grumet said in a statement. “It is time for the brawlers to get out of the way and let the builders get back to work.”

Fervo promotes strategy leader to COO as flagship geothermal project nears launch

new leader

Houston geothermal unicorn Fervo Energy has named Sarah Jewett as its new COO.

Jewett steps into the role as the company prepares for its flagship Cape Station geothermal project to deliver its first power later this year.

Jewett joined Fervo in 2020 as director of strategy and most recently served as the company's senior vice president of strategy. She spoke with HETI on the potential of geothermal energy in 2024.

Before Fervo, Jewett served as senior director of corporate development for Houston-based Select Energy Services. She ran hydraulic fracturing crews for Schlumberger in the Permian Basin and Alaska's North Slope early in her career.

In the COO role, Jewett is tasked with creating "the centralized infrastructure required to execute on what the company believes is the most significant commercial opportunity for clean, firm power in history," according to a company release.

“What Sarah has built over the last six years has been foundational to the company’s success. From the time she joined, she has brought an unwavering people-first mindset and outstanding dedication to building things that last,” Tim Latimer, CEO and co-founder of Fervo, added in the release. “As we move into the next phase of our growth, there is no better person to lead the operating core of this company.”

Jewett holds an MBA from Harvard Business School and a bachelor's degree in mechanical engineering from Dartmouth College.

Fervo announced the addition of four heavyweights to its board of directors this spring, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE. Shortly after, the company filed for its highly anticipated $1 billion-plus IPO. Read more here.

UH study finds Gulf Coast best positioned for emerging carbon removal technology

coastal impact

The Gulf Coast is an ideal spot for deploying a new ocean-based carbon removal technology that uses seawater to capture and store carbon dioxide, according to a new study from the University of Houston.

The study was led by UH Cullen College of Engineering Professor Mim Rahimi and published in Nature’s Communications Sustainability journal. Abdelrahman Refaie, a PhD student at UH, authored the paper. It aimed to develop a plan for implementing an electrochemical marine carbon dioxide removal (e-mCDR) technology that treats seawater to increase the ocean’s ability to absorb and store carbon dioxide from the air.

Currently, oceans absorb about 30 percent of human-produced carbon dioxide emissions each year, according to UH, making it a great natural resource for carbon removal.

The team at UH scouted and analyzed 38 coastal facilities across the U.S.—including power plants, desalination plants, and liquefied natural gas (LNG) terminals—before determining the Gulf Coast as an attractive option. The South Hub, or the Gulf Coast along Texas and Louisiana, ranked the top-performing area for the technology due to the industrial infrastructure, affordable electricity, hydrogen transportation and storage networks.

Other regions like California and the Northeast also scored well due to their clean energy mix and carbon removal potential, according to UH.

“The South hub has one of the highest diversity factors between power plants, desalination and LNG,” Refaie said in a news release. “That means if, logistically, down the road LNG is not open for this implementation, then we have another option in the area. It reduces the risk factor.”

UH says the findings show how companies could commercialize the technology, which could boost coastal economies.

“The question we had wasn’t technical, rather, it was logistical in regard to implementation down the road,” Rahimi said. “This would be a roadmap if a company or the government wants to utilize this technology.”

Rahimi aims to increase awareness about e-mCDR technology and its potential impact. He recently discussed the ocean-centric carbon removal work with members of Congress in March at the Carbon to Sea’s 2026 Hill Day.

“I think faculty at the University of Houston can do more of this kind of work,” Rahimi said in a separate release. “Meeting with Members of Congress gives us a chance to help policymakers better understand the science and engineering happening at our university. That kind of engagement is an important part of moving new technologies forward. It also shows how the work we do on campus can have a real impact on communities beyond the university.”
