Two months after its $400 million IPO, Houston-based ERock (NYSE: EROC) has landed a power-generator deal with AI powerhouse Anthropic, owner of the Claude platform.
In its Q2 earnings report, ERock says it will provide equipment to Anthropic with a 470-megawatt capacity. ERock specializes in utility-grade, onsite microgrid power systems for data centers and other customers. The company previously did business as Enchanted Rock.
The Anthropic deal adds to ERock’s backlog of about $1.7 billion in orders—a figure representing a 1,000 percent year-over-year jump in backorders thanks in large part to the AI boom. ERock expects most of the backlog to convert to revenue by the end of 2027, said Ian Blakely, the company’s chief financial officer.
Bank of America analyst Ross Fowler says the Anthropic contract boosts confidence in ERock’s ability to secure other major deals, according to Traders Union. The Anthropic deal is ERock’s third major data center contract, with separate Anthropic deals for operations and maintenance services expected to follow, Fowler said.
CEO John Carrington says Anthropic’s order “reinforces the momentum” ERock is witnessing across its customer base.
“We are seeing a lot of interest in Texas. It seems to be the easiest place to get a site set up,” company President Corey Amthor said
In its Q2 earnings release—its first as a public company—ERock also reported:
Launching generator-assembly operations at its Hyperion equipment factory in Northwest Houston. The plant will expand ERock’s assembly capabilities to 1.2 gigawatts of capacity by the end of 2026.
Starting construction of a $473 million, 366-megawatt El Paso Electric natural-gas-powered plant to supply power for Meta Platforms’ $14 billion, 1,000-acre AI data center campus in El Paso. Meta is the parent company of the Facebook and Instagram social media companies.
“Meta gains access to an operational data center years earlier than may otherwise be possible, while El Paso Electric gains a flexible, low-cost, low-emissions grid asset that can support long-term system reliability,” Carrington said.
Another energy company in Houston is going public amid a flurry of energy IPOs.
Houston-based ERock Inc., which specializes in utility-grade onsite microgrid systems for data centers and other customers, has filed paperwork with the U.S. Securities and Exchange Commission (SEC) to sell its shares on the New York Stock Exchange.
The ERock filing follows the recent $1.9 billion IPO of Houston-based Fervo Energy, a provider of geothermal power that’s now valued at $7.7 billion.
Another Houston energy company, EagleRock Land, just went public in a $320 million IPO that values the company at $3 billion. EagleRock owns or controls about 236,000 acres in the Permian Basin, earning money from royalties, fees, easements, water services and other revenue streams tied to drilling on its land.
ERock’s SEC filing doesn’t identify the per-share pricing range for the IPO or the number of Class A shares to be offered. ERock is a portfolio company of Energy Impact Partners, a New York City-based venture capital and private equity firm that invests in energy companies.
The company previously did business as Enchanted Rock. ERock Inc., formed in January, will function as a holding company that controls predecessor company ER Holdings Ltd.
In 2025, ERock generated revenue of $183.1 million, up 42.5 percent from the previous year, according to the IPO filing. It recorded a net loss of $59 million last year.
As of March 31, ERock boasted a sales backlog of nearly $1.3 billion, up 779 percent on a year-over-year basis. The company attributes most of that increase to greater demand from data centers.
The company primarily serves the power needs of data centers, utilities, industrial facilities, and commercial buildings. Its biggest markets are Texas and California.
“Several U.S. markets, such as Texas and California, face especially acute reliability risks,” ERock says in the SEC filing. “Texas already shows rapid load-growth pressures tied to data centers and industrial expansion, while California faces grid congestion, long interconnection queues, and above-average vulnerability to extreme heat- and weather-driven outages.”
Since its founding in 2018, ERock has installed microgrid systems at more than 400 sites with a capacity of about 1,000 megawatts. Customers include ComEd, Foxconn, H-E-B, Microsoft and Walmart.
By the end of this year, the company plans to expand its production of microgrid systems to a capacity of about 1.2 gigawatts with the opening of its Hyperion facility in Houston.
John Carrington leads ERock as CEO. He joined ER Holdings last year as chairman and CEO. Carrington previously was CEO of Houston-based Stem, a public company that offers AI-enabled clean energy software and services. Earlier, he spent 16 years at General Electric.

Carrington most recently was CEO of Houston-based Stem, which offers AI-enabled software and services designed for setting up and operating clean energy facilities. He stepped down as Stem’s CEO in September 2024. Stem, which was founded in 2006 and went public under Carrington's leadership in 2021, was previously based in San Francisco.
Carrington has also held senior leadership roles at Miasolé, First Solar and GE.
Corey Amthor has served as acting CEO of Enchanted Rock since June. He succeeded Enchanted Rock founder Thomas McAndrew in the role, with McAndrew staying on with the company as a strategic advisor and board member. With the hiring of Carrington, Amthor has returned to his role as president. According to the company, Amthor and Carrington will "partner to drive the company’s next phase of growth."
“I’m proud to join a leadership team known for technical excellence and execution, and with our company-wide commitment to innovation, we are well positioned to navigate this moment of unprecedented demand and advance our mission alongside our customers nationwide,” Carrington said in the news release. “Enchanted Rock’s technology platform delivers resilient, clean and scalable ultra-low-emissions onsite power that solves some of the most urgent challenges facing our country today. I’m energized by the strong momentum and growing market demand for our solutions, and we remain committed to providing data centers and other critical sectors with the reliable power essential to their operations.”
This summer, Enchanted Rock also announced that Ian Blakely would reassume the role of CFO at the company. He previously served as chief strategy officer. Paul Froutan, Enchanted Rock's former CTO, was also named COO last year.

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.”

Houston-based Enchanted Rock, which provides dual-purpose microgrids, announced that Paul Froutan has been named COO.
Froutan joined Enchanted Rock in 2022 as the chief technology officer. He will replace Thais Grossi, who served in the role for nearly eight years.
Froutan previously led Google's Global Data Center Operations and was responsible for managing Google's worldwide data center and server operations. He also served as the vice president of engineering for Rackspace Hosting, and holds a Bachelor of Science in mechanical engineering and an MBA from the University of Texas at Austin.
“Since joining Enchanted Rock, I've been impressed with the team's vast knowledge of natural gas microgrids and how that has been applied to deliver both customer resiliency and financial value," Froutan says in a news release. "Taking the next step and bringing technology, EPC, and O&M together under one umbrella will further improve our innovation feedback loop, which benefits our customers and the communities that rely on our services."
In his previous role with the company, Froutan was responsible for GraniteEcoSystem, Enchanted Rock's microgrid management software, and the launch of the company's advanced natural gas generator initiative. Froutan will lead the product engineering, EPC, and operations and maintenance teams.
"Paul has helped take the technology and intelligence powering our solutions to the next level, and we are pleased that he has accepted this expanded role," Thomas McAndrew, CEO of Enchanted Rock, says in a news release. "His understanding of emerging technologies and operational excellence, paired with his extensive experience leading high-performing teams, make him an excellent choice to continue our commitment to deliver customer-focused solutions. We are also extremely grateful for Thais' dedication to the Enchanted Rock team and our customers."
Enchanted Rock's electrical microgrids use natural gas and renewable natural gas to help produce lower carbon emissions and air pollutants than diesel generators,and are capable of achieving resiliency with net-zero emissions. The company recently received a $2.1 million grant from the California Energy Commission for development of technology aimed at reducing greenhouse gasses and other natural gas emissions. Enchanted Rock will share the grant with the University of California Riverside, or UCR.

An innovative Houston-area company is on a mission to make using hydrogen energy easier and cheaper.
A recently announced partnership with investment firm, Balcor Companies, will help make this a reality as Kaizen Clean Energy looks to make hydrogen energy more accessible, reliable and affordable. Announced July 6, Balcor now has an ownership stake in Kaizen. The terms of the deal were not disclosed.
The company, based in Tomball, has developed a “micro grid” hydrogen power station — a mobile, scalable energy source that can be used anywhere, anytime.
Balcor Companies Founder and Director Chris Balat says his company is looking at their stake in KCE as an investment in shaping a more sustainable world.
“We are thrilled to make our first foray into the energy sector with Kaizen Energy as our trusted partner,” he says in a statement. "Our association with Kaizen is a testament to our commitment towards a sustainable future, driving positive change in the world while delivering value to our stakeholders.”
Kaizen's mission is to succeed where electric grids fail. One fallback source to help strained electric grids has typically been diesel generators. However, diesel generators increase local emissions which produce a significant amount of air pollution and health concerns. Kaizen’s hydrogen generators can be used to power buildings, homes, hospitals, data centers, events, and farm equipment. They are portable, which means it does not require any excessive infrastructure.
“Our system allows customers the ability to have renewable energy anywhere in the world in a very short time frame,” said Eric Smith, co-founder of KCE. “For EV charging, for power generation, to replace a diesel generator.”
Smith tells EnergyCapitalhtx the concept is very attractive to corporations who lease buildings as building out a permanent infrastructure could be costly and time consuming.
Robert Meaney, a Texas Tech engineering graduate, founded Kaizen Clean Energy in 2020, along with Eric Smith and Craig Klaasmeyer. Meaney designed the technology using a mixture of methanol and water to create hydrogen. A 330-gallon tank of the mixture produces about 150 kilograms of hydrogen — or 1.6 megawatt-hours of energy. The mixture lowers the risks of many of the drawbacks of hydrogen usage. For example, it can be stored for longer periods and transported long distances safely.
The microgrid fits into a small container and can be dropped on site at remote locations or in heavily congested grid areas. It also eliminates the cost of hydrogen transportation by generating hydrogen on-site with commonly available methanol, which can be both used for hydrogen fuel and converted to electricity for electric vehicle charging. This microgrid technology can both connect to the grid to supplement available power, or can be used during a power outage.
To put this energy source to use, KCE has partnered with Extreme E, an international off-road racing series that is part of Formula 1 and uses electric SUV’s to race in remote parts of the world. Kaizen’s units are also being used at a fleet-charging location in Los Angeles.
Nearly 20 companies from Houston, ranging from global multinationals to innovative startups, joined the team at Argonne National Laboratory in Lemont, Illinois, for a full day of meetings, discussions, and networking focused on advancing innovation, commercialization, and industry collaboration.
The fly-in organized by the Houston Energy Transition Initiative, provided a unique opportunity for companies to engage directly with Argonne researchers, technical experts, and leadership while gaining a deeper understanding of the laboratory’s world-class capabilities. Participants explored how national laboratories can help bridge the gap between breakthrough research and commercial deployment, particularly in areas critical to U.S. competitiveness and economic growth.
The significance of this engagement extends beyond a single visit. While the U.S. Department of Energy operates 17 national laboratories, none is located along the Gulf Coast, a region uniquely home to industry, infrastructure, and energy systems at commercial scale. HETI’s continued work with the national laboratories helps bridge that geographic and operational gap by connecting world-class scientific research with companies that understand how to scale and deploy technologies. The Argonne fly-in also created space to address practical barriers to collaboration, including complex agreements and lengthy contracting timelines, and to explore ways to establish partnership frameworks more efficiently.
Explore HETI’s key takeaways from the fly-in:
1. Scaling Technologies for Commercial Use
A central theme was the importance of scale-up infrastructure and the role Argonne plays in helping companies reduce technical and manufacturing risks. Participants learned how facilities such as the Materials Engineering Research Facility (MERF) support the transition from laboratory discoveries to pilot-scale production and ultimately commercial manufacturing. These capabilities are especially valuable for companies working to move promising technologies from concept to market.
The discussions also highlighted Argonne’s extensive work in critical materials, battery recycling, advanced manufacturing, and supply chain resilience. Attendees learned about initiatives including the ReCell Center, AI-enabled materials discovery, and advanced modeling tools that can help businesses understand supply chain vulnerabilities and evaluate mitigation strategies. These capabilities have applications across energy, chemicals, manufacturing, semiconductors, defense, and emerging technologies.
2. Creating Pathways for Collaboration
Another key takeaway was the importance of engaging early. Companies do not need to arrive with a fully developed project or solution. Argonne offers multiple pathways for collaboration, including sponsored research, user facility access, technology licensing, pilot-scale testing, and Cooperative Research and Development Agreements (CRADAs). These partnerships help companies access specialized expertise, facilities, and analytical tools that can accelerate innovation and commercialization
3. Building Connections Across Industry and Research
The fly-in reinforced the value of relationship building. Bringing together nearly 20 organizations in one place created meaningful opportunities for collaboration, knowledge sharing, and identifying future projects.
The conversations throughout the day demonstrated a shared commitment to strengthening domestic innovation, developing resilient supply chains, and creating pathways to bring new technologies to market.
Fervo Energy’s flagship project in Utah just generated its first geothermal power.
The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.
The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).
“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.
The plant’s two other units are scheduled to launch commercial operations on Jan. 1.
The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.
Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.
“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”
Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
While hundreds of thousands descend on New York for Climate Week, Houston offered a different proposition: come where the work is being built. And last week Houston proved that it’s solving for more energy and fewer emissions; reliability and affordability; speed and durability. We are solving for the “&.”
That equation sharpened last week. On Sept. 14, the Environmental Protection Agency announced it had repealed most 2024 federal carbon-pollution standards for power plants and proposed rescinding remaining greenhouse-gas requirements. Policy matters, but it can pivot. The need to build does not.
HECW is a proving ground, not another conference stop. As I wrote in the Houston Chronicle, Mayor Sylvester Turner planted the seed by insisting we bring people together across the city and industry to drive Houston’s energy future. He knew false choices have no place here: oil and gas and clean technology; prosperity and stewardship; industry and lower emissions.
ECW joined the Climate Week Network this year, connecting Houston to a growing community of more than 500,000 people across 22-plus cities. We now have a seat at the global table—and a responsibility to use it well, building with other cities and the wider clean-energy-solutions world rather than merely talking at them.
The capital is already moving. Since 2017, Houston Energy Transition Initiative member companies have invested more than $95 billion in low-carbon infrastructure, technologies, and research and development. This is where the transition is financed, engineered, tested and operated. But the work requires more than capital. It requires capital allocators who understand the difference between a promising idea and a project that can scale, hire and endure.
Last week was Houston’s show and tell. At ARTECHOUSE, The &Bassador Reception & Awards brought art, technology, culture, philanthropy and energy together. Then the week went beyond downtown.
Sugar Land Town Square became the launchpad for the Metro Innovation Tour & Market: a place for an ecosystem conversation about smart cities, clean energy, equitable access and next-generation mobility before participants boarded three tour routes across greater Houston. It was also the starting point for the Bay City South Innovation Tour to Erthos Project Bravo in Matagorda County, where small groups saw Earth Mount solar modules being installed in real time. The conversation did not end at a panel. It went to the project site.

Approximately 100 startups from around the world pitched at Rice Alliance, Greentown Labs and Halliburton Labs events. At Astros Night at Daikin Park, builders, backers, and believers traded conference rooms for the diamond, creating an experience, not just another event. That is how this work becomes civic fabric.
Activation also means making the energy story felt, not merely explained. AY Young brought the Battery Tour for live performances. It was a reminder that the “Power of &” is not confined to a boardroom or a laboratory. Art and technology, culture and commerce, a new generation and established industry can share the same stage—and help more people see themselves in the work ahead.
Perhaps no activation made the “Power of &” more immediate and real than the Houston, We Have Solutions open mic night. At Creatopia’s Innovation Studio, people took the mic—or simply listened—to share what they were building, the problem they could not stop thinking about, and the connection they hoped to make. It put founders, artists, community builders, researchers and future-makers in one room. That is collaboration in real time: different kinds of expertise meeting before anyone knows exactly what the solution will be.
FOX26 helped carry that story beyond the rooms we convened, hosting Erthos COO Jessica Knight, Mars Materials co-founder Aaron Fitzgerald, and investors Taylor Chapman and Juliana Garaizar to discuss building and backing the future in Houston. Our region should be proud—not as self-congratulation, but because the world is beginning to experience energy and climate solutions firsthand.
This was also a week to give back. Allies in Energy awarded $27,500 to nine organizations advancing energy and climate literacy, civil dialogue, workforce pathways and community action. NRG Energy’s Brighter Communities provided a founding gift to expand the week and fund local grants. It took partners, hosts, sponsors, volunteers, funders and community organizations. That is the “Power of &”: collaboration that leaves a stronger community behind.
The “Power of &” cannot stop at Houston’s city limits. Louisiana’s participation—through its support of the Digital Delta Symposium & Expo—made clear that Houston’s builder ecosystem is regional by necessity. Gulf Coast infrastructure, supply chains, talent, and industrial decisions do not recognize state lines. Neither should our collaboration. If we are serious about building more energy with fewer emissions, we must align capital, resources and opportunity across the entire Gulf Coast.
That same commitment to practical collaboration means listening, learning and adjusting. A builder’s mindset does not protect a plan simply because it came first; it improves the conditions for the work to succeed. That is why Houston Energy and Climate Week will move to April 4–10, 2027—better weather, more time and space for connection, and a stronger city-wide experience for the people building what comes next.
But the real test begins now. Can we keep widening the circle? Can we continue to turn research into projects, pilots into infrastructure, capital into good jobs and climate ambition into results that families and communities can see? Can we make every new solution stronger by bringing in the people who must finance it, build it, operate it, live beside it and benefit from it?
That is the work ahead. Turner understood that Houston does not move forward by asking who wins the argument. It moves forward by asking who is ready to solve the problem. His legacy—and the promise of the “&”—is an invitation to choose collaboration over division, action over performance and possibility over false choices.
The future does not need another city to talk about it. It needs Houston to keep building it. And it will only be built if we keep choosing the "&."
