Research from the Federal Reserve Bank of Dallas shows that solar power and battery storage capacity helped stabilize Texas’ electric grid last summer.

Between June 1 and Aug. 31, solar power met nearly 25 percent of midday electricity demand within the Electric Reliability Council of Texas (ERCOT) power grid. Rising solar and battery output in ERCOT assisted Texans during a summer of triple-digit heat and record load demands, but the report fears that the state’s power load will be “pushed to its limits” soon.

The report examined how the grid performed during more demanding hours. At peak times, between 11 a.m. and 2 p.m. in the summer of 2024, solar output averaged nearly 17,000 megawatts compared with 12,000 megawatts during those hours in the previous year. Between 6 p.m. and 9 p.m., discharge from battery facilities averaged 714 megawatts in 2024 after averaging 238 megawatts for those hours in 2023. Solar and battery output have continued to grow since then, according to the report.

“Batteries made a meaningful contribution to what those shoulder periods look like and how much scarcity we get into during these peak events,” ERCOT CEO Pablo Vegas said at a board of directors conference call.

Increases in capacity from solar and battery-storage power in 2024 also eclipsed those of 2023. In 2023 ECOT added 4,570 megawatts of solar, compared to adding nearly 9,700 megawatts in 2024. Growth in battery storage capacity also increased from about 1,500 megawatts added in 2023 to more than 4,000 megawatts added in 2024. Natural gas capacity also saw increases while wind capacity dropped by about 50 percent.

Texas’ installation of utility-scale solar surpassed California’s in the spring of last year, and jumped from 1,900 megawatts in 2019 to over 20,000 megawatts in 2024 with solar meeting about 50 percent of Texas' peak power demand during some days.

While the numbers are encouraging, the report states that there could be future challenges, as more generating capacity will be required due to data center construction and broader electrification trends. The development of generating more capacity will rely on multiple factors like price signals and market conditions that invite more baseload and dispatchable generating capacity, which includes longer-duration batteries, and investment in power purchase agreements and other power arrangements by large-scale consumers, according to the report.

Additionally, peak demand during winter freezes presents challenges not seen in the summer. For example, in colder months, peak electricity demand often occurs in the early morning before solar energy is available, and it predicts that current battery storage may be insufficient to meet the demand. The analysis indicated a 50% chance of rolling outages during a cold snap similar to December 2022 and an 80% chance if conditions mirror the February 2021 deep freeze at the grid’s current state.

The report also claimed that ERCOT’s energy-only market design and new incentive structures, such as the Texas Energy Fund, do not appear to be enough to meet the predicted future magnitude and speed of load growth.

Google to invest $1B in clean energy, data center tech in Texas

money moves

Google is making a big investment in Texas to the tune of $1 billion.

According to a news release from the company, the tech giant will spend more than $1 billion to support its cloud and data center infrastructure and expand its commitment to clean energy.

The $1 billion will be spent on data center campuses in Midlothian and Red Oak to help meet growing demand for Google Cloud, AI innovations, and other digital products and services such as Search, Maps, and Workspace.

In addition to its data center investment, Google has also forged long-term power purchase agreements with Houston-based Engie, as well as Madrid-based entities Elawan, Grupo Cobra, and X-ELIO for solar energy based in Texas. Together, these new agreements are expected to provide 375 MW of carbon-free energy capacity, which will help support Google’s operations in Texas.

These agreements were facilitated through LEAP (LevelTen Energy’s Accelerated Process), which was co-developed by Google and LevelTen Energy to make sourcing and executing clean energy PPAs more efficient, and contributes to the company’s ambitious 2030 goal to run on 24/7 carbon-free energy on every grid where it operates.

The company has contracted with energy partners to bring more than 2,800 megawatts (MW) of new wind and solar projects to the state. Google’s CFE percentage in the ERCOT grid region, which powers its Texas data centers, nearly doubled from 41 percent in 2022 to 79 percent in 2023.

The initiatives were announced at a conference in Midlothian on August 15, attended by business leaders and politicians including U.S. Congressman Jake Ellzey, Google Cloud VP Yolande Piazza, Ted Cruz, and Citi CIO Shadman Zafar.

The Dallas cloud region is part of Google Cloud's global network of 40 regions that delivers services to large enterprises, startups, and public sector organizations.

In a statement, Piazza said that "expanding our cloud and data center infrastructure in Midlothian and Red Oak reflects our confidence in the state's ability to lead in the digital economy."

Data centers are the engines behind the growing digital economy. Google has helped train more than 1 million residents in digital skills through partnerships with 590 local organizations, including public libraries, chambers of commerce, and community colleges.

In addition to its cloud region and Midlothian data center, Google has offices in Austin, Dallas, and Houston. The new Google’s total investment in Texas to more than $2.7 billion.

Houston-based clean energy site developer raises $300M to decarbonize big tech projects

seeing green

Houston energy executives have started a new company dedicated to developing clean-powered infrastructure for the large electric loads.

Cloverleaf Infrastructure, dually headquartered in Houston and Seattle, Washington, announced its launch and $300 million raised from NGP and Sandbrook Capital, two private equity firms. The company's management team also invested in the company.

As emerging technology continues to grow electricity load demand, Cloverleaf has identified an opportunity to develop large-scale digital infrastructure sites powered by low-carbon electricity.

"The rapid growth in demand for electricity to power cloud computing and artificial intelligence poses a major climate risk if fueled by high-emission fossil fuels," David Berry, Cloverleaf's CEO, says in a news release. "However, it's also a major opportunity to catalyze the modernization of the US grid and the transition to a smarter and more sustainable electricity system through a novel approach to development.

"Cloverleaf is committed to making this vision a reality with the support of leading climate investors like Sandbrook and NGP."

Berry, who's based in Houston, previously co-founded and served as CFO at ConnectGen and Clean Line Energy Partners, clean energy and transmission developers. Last year, he co-founded Cloverleaf with Seattle-based Brian Janous and CTO Jonathan Abebe, who most recently held a senior role at the United States Department of Energy. Nur Bernhardt, director of Energy Strategy at Microsoft who's also based in Seattle, rounds out the executive team as vice president.

"The large tech companies have become dominant players in the electricity sector, and they are genuinely determined to power their growth with the lowest possible emissions," Janous, who serves as chief commercial officer, says in the release. "Achieving this objective doesn't depend on disruptive new technologies as much as it does on dedicated teams working hand in hand with utility partners to maximize the use of the clean generation, storage, and other technologies we already have."

Cloverleaf will work with regional U.S. utilities and data center operators to provide clean electricity at scale through strategic investments in transmission, grid interconnection, land, onsite power generation, and electricity storage, per the release.

"The sustainable development of digital infrastructure at scale is fundamentally a technical power problem," Alfredo Marti, partner at Sandbrook, adds. "We have witnessed members of the Cloverleaf team effectively address this challenge for many years through a blend of creativity, specialized engineering, a partnership mindset, and astute capital deployment."

New collaboration to build data center microgrid in Houston

coming soon

Two companies are teaming up to build a natural gas microgrid in Houston that will reduce emissions by 98 percent.

Provider of prime and backup power solutions RPower has teamed up with Houston’s ViVaVerse Solutions to build a 17-megawatt (MW) microgrid at the ViVa Center campus in Houston, which is expected to be commissioned by the end of the year.

The microgrid plans to employ ultra-low emissions and natural gas generators to deliver Resiliency-as-a-Service (RaaS), and this will connect to ViVaVerse's colocation data center operations during utility outages.

RPower will also deploy the microgrid across different ERCOT market programs, which will contribute to assist with essential capacity and ancillary services for the local grid. ERCOT has increased its use of renewable energy in recent years, but still has faced criticism for unstable conditions. The microgrids can potentially assist ERCOT, and also help cut back on emissions.

“RPower's pioneering microgrid will not only deliver essential N+1 resiliency to our data center operations but will also contribute to the local community by supplying necessary capacity during peak demand periods when the electric grid is strained,” Eduardo Morales, CEO of ViVaVerse Solutions and Morales Capital Group, says in a news release.

ViVaVerse Solutions will be converting the former Compaq Computer/HPE headquarters Campus into an innovative technology hub called the ViVa Center, which will host the High-Performance Computing Data Center, and spaces dedicated to mission critical infrastructure and technical facilities . The hub will host 200 data labs.

“We are thrilled to partner with ViVaVerse to deploy this `first of its kind' microgrid solution in the data center space,” Jeff Starcher, CEO of RPower, adds. “Our natural gas backup generation system delivers the same reliability and performance as traditional diesel systems, but with a 98 percent reduction in emissions. Further, the RPower system provides critical grid services and will respond to the volatility of renewable generation, further enabling the energy transition to a carbon free future.”

Texas university's 'WaterHub' will dramatically reduce water usage by 40%

Sustainable Move

A major advancement in sustainability is coming to one Texas university. A new UT WaterHub at the University of Texas at Austin will be the largest facility of its kind in the U.S. and will transform how the university manages its water resources.

It's designed to work with natural processes instead of against them for water savings of an estimated 40 percent. It's slated for completion in late 2027.

The university has had an active water recovery program since the 1980s. Still, water is becoming an increasing concern in Austin. According to Texas Living Waters, a coalition of conservation groups, Texas loses enough water annually to fill Lady Bird Lake roughly 89 times over.

As Austin continues to expand and face water shortages, the region's water supply faces increased pressure. The UT WaterHub plans to address this challenge by recycling water for campus energy operations, helping preserve water resources for both the university and local communities.

The 9,600-square-foot water treatment facility will use an innovative filtration approach. To reduce reliance on expensive machinery and chemicals, the system uses plants to naturally filter water and gravity to pull it in the direction it needs to go. Used water will be gathered from a new collection point near the Darrell K Royal Texas Memorial Stadium and transported to the WaterHub, located in the heart of the engineering district. The facility's design includes a greenhouse viewable to the public, serving as an interactive learning space.

Beyond water conservation, the facility is designed to protect the university against extreme weather events like winter storms. This new initiative will create a reliable backup water supply while decreasing university water usage, and will even reduce wastewater sent to the city by up to 70 percent.

H2O Innovation, UT’s collaborator in this project, specializes in water solutions, helping organizations manage their water efficiently.

"By combining cutting-edge technology with our innovative financing approach, we’re making it easier for organizations to adopt sustainable water practices that benefit both their bottom line and the environment, paving a step forward in water positivity,” said H2O Innovation president and CEO Frédéric Dugré in a press release.

The university expects significant cost savings with this project, since it won't have to spend as much on buying water from the city or paying fees to dispose of used water. Over the next several years, this could add up to millions of dollars.

Houston clean energy pioneer earns prestigious Welch Foundation award

Awards Season

A Rice University professor has earned a prestigious award from the Houston-based Welch Foundation, which supports chemistry research.

The foundation gave its 2025 Norman Hackerman Award in Chemical Research to Haotian Wang for his “exceptionally creative” research involving carbon dioxide electrochemistry. His research enables CO2 to be converted into valuable chemicals and fuels.

The award included $100,000 and a bronze sculpture.

“Dr. Wang’s extensive body of work and rigorous pursuit of efficient electrochemical solutions to practical problems set him apart as a top innovator among early-career researchers,” Catherine Murphy, chairwoman of the foundation’s Scientific Advisory Board, said in a news release.

Wang is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice. The department’s Wang Group develops nanomaterials and electrolyzers for energy and environmental uses, such as energy storage, chemical and fuel generation, green synthesis and water treatment.

Wang also is co-founder of Solidec, a Houston startup that aims to turn his innovations into low-carbon fuels, carbon-negative hydrogen and carbon-neutral peroxide. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions.

Solidec has been selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

“Dr. Wang’s use of electrochemistry to close the carbon cycle and develop renewable sources of industrial chemicals directly intersects with the Welch Foundation mission of advancing chemistry while improving life,” Fred Brazelton, chairman and director of the Welch Foundation, said in the release.

Ramamoorthy Ramesh, executive vice president for research at Rice University, added: “We are proud to (Dr. Wang) at Rice. He’s using chemical engineering to solve a big problem for humanity, everything that the Welch Foundation stands for.”

Last year, the Hackerman Award went to Baylor College of Medicine's Livia Schiavinato Eberlin, who's known for her groundbreaking work in the application of mass spectrometry technologies, which are changing how physicians treat cancer and analyze tissues. Read more here.
