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.

Buoyed by $1.3B sales backlog, microgrid company ERock files for IPO

eyeing ipo

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.

According to Barron’s, more than a dozen energy and energy-related companies in the U.S. have gone public since the beginning of 2025, with the bulk of the IPOs happening this year.

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.

Houston microgrid company names new CEO

new hire

Houston-based electric microgrid company Enchanted Rock has named a new CEO.

John Carrington has assumed the role after serving as Enchanted Rock's executive chairman since June, the company announced earlier this month.

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.

ERCOT approves $9.4B project to improve grid, meet data center demand

power project

The Electric Reliability Council of Texas, which manages the electric grid for 90 percent of Texans, is undertaking a $9.4 billion project to improve the reliability and efficiency of statewide power distribution. The initiative comes as ERCOT copes with escalating demand for electricity from data centers and cryptocurrency-mining facilities.

The project, approved Dec. 9 by ERCOT’s board, will involve building a 1,109-mile “super highway” of new 765-kilovolt transmission lines. One kilovolt equals 1,000 volts of electricity.

According to the Hoodline Dallas news site, the $9.4 billion project represents the five- to six-year first phase of ERCOT’s Strategic Transmission Expansion Plan (STEP). Hoodline says the plan, whose price tag is nearly $33 billion, calls for 2,468 miles of new 765-kilovolt power lines.

STEP will enable ERCOT to “move power longer distances with fewer losses,” Hoodline reports.

Upgrading the ERCOT grid is a key priority amid continued population growth in Texas, along with the state’s explosion of new data centers and cryptocurrency-mining facilities.

ERCOT says about 11,000 megawatts of new power generation capacity have been added to the ERCOT grid since last winter.

But in a report released ahead of the December board meeting, ERCOT says it received 225 requests this year from large power users to connect to its grid — a 270 percent uptick in the number of megawatts being sought by mega-users since last December. Nearly three-fourths (73 percent) of the requests came from data centers.

Allan Schurr, chief commercial officer of Houston-based Enchanted Rock, a provider of products and services for microgrids and onsite power generation, tells Energy Capital that the quickly expanding data center industry is putting “unprecedented pressure” on ERCOT’s grid.

“While the state has added new generation and transmission capacity, lengthy interconnection timelines and grid-planning limitations mean that supply and transmission are not keeping pace with this rapid expansion,” Schurr says. “This impacts both reliability and affordability.”

For families in Texas, this could result in higher energy bills, he says. Meanwhile, critical facilities like hospitals and grocery stores face a heightened challenge of preventing power outages during extreme weather or at other times when the ERCOT grid is taxed.

“I expect this trend to continue as AI and high-density computing grow, driving higher peak demand and greater grid variability — made even more complex by more renewables, extreme weather and other large energy users, like manufacturers,” Schurr says.

According to the Pew Research Center, data centers accounted for 4 percent of U.S. electricity use in 2024, and power demand from data centers is expected to more than double by 2030. Data centers that support the AI boom make up much of the rising demand.

In September, RBN Energy reported more than 10 massive data-center campuses had been announced in Texas, with dozens more planned. The Lone Star State is already home to roughly 400 data centers.

“Texas easily ranks among the nation’s top states for existing data centers, with only Virginia edging it out in both data-center count and associated power demand,” says RBN Energy.

Houston expert on why companies are investing in sustainable energy technology

guest column

In a modern business landscape characterized by increasing uncertainty and volatility, energy resilience has emerged as a cornerstone of strategic decision-making.

Let's delve deeper into why executives should view energy resilience as one of the best risk management investments they can make.

Mitigating risks and enhancing stability

Investing in energy resilience isn't solely about averting risks; it's about mitigating the potential losses that could arise from energy-related disruptions. It is estimated that half of today’s businesses lack an effective resilience strategy, even though nearly 97 percent of companies have been impacted by a critical risk event.

Whether it's power outages from extreme weather events, grid emergencies from a changing resource mix that is more weather dependent or cyber-attacks, disruptions can inflict substantial financial and reputational damage on businesses. By implementing resilient energy infrastructure and practices, organizations can minimize the impact of such disruptions, ensuring consistent operations even in the face of adversity. As an added benefit, these investments can also contribute to enhancing the stability of our grid infrastructure, benefiting not just individual businesses but the local community and the entire economy.

Improving costs and operational efficiency

Energy resilience also isn't just a defensive strategy; it's also about optimizing costs and operational efficiency to create competitive advantage. By investing in resilient energy infrastructure, such as backup power systems and microgrids, businesses can reduce the downtime associated with energy disruptions, thus avoiding revenue losses and operational inefficiencies.

Additionally, resilient energy solutions often lead to long-term cost savings through increased energy efficiency and reduced reliance on costly backup systems. As circumstances become increasingly uncertain, businesses that prioritize energy resilience can gain a competitive edge by operating more efficiently and cost-effectively than their counterparts.

Ensuring consistent operations amidst uncertainty

In today's rapidly changing business environment, characterized by geopolitical tensions, climate change, and technological advancements, uncertainty has become the new normal. Amidst this uncertainty, ensuring consistent operations is paramount for business continuity and long-term success. Investing in energy resilience provides businesses with the assurance that they can maintain operations even in the face of unforeseen challenges.

Whether it's a sudden power outage from a storm or the grid is stressed and unable to deliver reliable power, resilient energy infrastructure enables organizations to adapt swiftly and continue delivering products and services to customers without interruption.

Enhancing sustainability efforts

In recent years, a growing emphasis on sustainability and environmental stewardship has led to organizations recognizing the importance of reducing their carbon footprint and transitioning towards cleaner, renewable energy sources. Investing in energy resilience provides an opportunity to align sustainability efforts with business objectives.

By integrating renewable energy technologies and energy-efficient practices into their resilience strategies, organizations can not only enhance their environmental performance but also achieve long-term cost savings, ensure regulatory compliance, and build stakeholder trust.

The value of energy resilience for businesses

It is not enough to successfully handle day-to-day operations anymore; organizations need to be prepared for unpredictable events with a reliable energy supply and backup plan. Recently, a hospital in Texas had to evacuate patients and experienced heavy financial losses due to the failure of their traditional diesel generators during an extended outage.

After reevaluating their resiliency strategy, they decided to implement full-facility backup power using Enchanted Rock’s dual-purpose managed microgrid solution, which kept their power on during the next outage and ensured both patient safety and full operational capabilities. Investing in an energy resilience strategy like a microgrid will mitigate these risks and ensure always-on power in times of uncertainty.

A responsible decision for the greater good

Beyond the immediate benefits to individual businesses, investing in energy resilience is also a responsible decision for the greater good. As businesses become increasingly reliant on the grid infrastructure, ensuring its resilience is essential for the stability and reliability of the entire energy ecosystem. By proactively investing in resilient energy solutions, for themselves, businesses also contribute to strengthening the grid infrastructure, reducing the risk of widespread outages, and promoting the overall resilience of the energy system.

Executives must recognize the strategic imperative of investing in resilient energy infrastructure like microgrid systems, which can provide a competitive advantage against organizations that do not have similar measures in place. In doing so, they can navigate uncertainty with confidence, set their business up for future success, and emerge stronger and more resilient than ever before.

Solid-state generator company secures $9M in financing, names CTO

fresh financing

ATS Energy has secured a $9 million investment to help commercialize its solid-state generator technology, a representative from the company tells Energy Capital.

The Colorado-based company is a member of Houston's Greentown Labs climatech community and was named the second most-promising startup in the Innovations for Traditional Energy, Electricity, & the Grid track during CERA Week's Energy Venture Day and Pitch Competition in March.

ATS's technology converts industrial waste heat into electricity via its proprietary thermoelectric cartridges, according to a news release. The cartridges convert the otherwise wasted thermal energy directly into usable electricity with no turbine, no moving parts and no emissions.

"We have spent years building a proven track record of breakthrough technology," Doug Hudson, CEO of ATS Energy, said in the release. "What has developed over the past year is that markets are moving toward ATS Energy, said in the release. We've moved well beyond early interest to commercial commitments, active proposals and a pipeline that continues to expand across multiple industrial sectors. That puts us in a tremendous position to meet the moment in delivering energy to industry. This investment responds to real commercial opportunity, and it positions ATS Energy to scale production, meet customer demand faster, and drive commercial deployments."

According to the release, ATS plans to complete and deploy its first commercial generator using the thermoelectric cartridges by mid-2027. The company shared that it plans to begin revenue-generating operations next year, as well.

ATS has also named Edward Ganja as its new CTO. Ganja previously served as a technology advisor for ATS and spent more than 30 years at Shell, most recently as vice president of catalyst and analytical technology in Houston, according to LinkedIn.

"Having worked closely with the team as a Technology Adviser, I am thrilled to step into the Chief Technology Officer role to lead our technology strategy and advanced materials scale-up," Ganja shared in a LinkedIn post. "ATS is tackling crucial energy challenges, and I look forward to working with our talented team, partners, and industry colleagues to accelerate our commercial development and technological footprint."

A representative from the company shares that ATS has three employees in Texas, including two in Houston. The company is targeting industrial facilities, including Gulf Coast refineries and petrochemical plants, for its production model, which will leverage established manufacturing capabilities to help quickly scale its commercial pipeline.

"We are scaling manufacturing with the discipline required for commercial-grade industrial deployment, moving beyond proof-of-concept to deliver mission-critical equipment," Terry Hill, COO of ATS, added in the release. "We've been building the supply chain, identifying the right manufacturing partners and putting the processes in place to move toward repeatable production. By leveraging contract manufacturing, we can focus our capital on the technology, the product and our customers rather than building factories. Just as importantly, we're working to reduce the time between installations so we can respond to the demand we're seeing in the market."

ATS won the prestigious Earthshot Prize in the Fix Our Climate category in 2024. The Earthshot Prize, founded by Prince William, awards £1 million to five energy startups each year over a decade.

Trump says he's ending restrictions on methane emissions from oil drilling

In the News

President Donald Trump said Tuesday that his administration is “terminating” a Biden-era rule that aimed to cut planet-warming emissions of methane from oil and gas drilling.

Trump said during a campaign rally in Texas that the change would save companies and consumers billions of dollars and unlock 210 million barrels of oil. That’s equivalent to about 10 days of U.S. petroleum consumption.

The move aims to encourage more domestic drilling as Trump faces criticism over high fuel prices amid the war in Iran.

Methane is responsible for about a third of planet-warming greenhouse gas emissions, scientists estimate.

Cuts in methane emissions have emerged in recent years as a global priority to slow the rate of climate change. Oil and gas operations are the largest industrial source of methane, which is the main component in natural gas and far more potent to the atmosphere than carbon dioxide in the short term.

The invisible gas leaks from equipment and is released into the atmosphere or burned off as a waste product by oil drillers.

Environmental Protection Agency Administrator Lee Zeldin previewed the changes last month, saying they would eliminate the agency’s “Super Emitter Program” that requires companies to investigate and repair major methane releases from oil and natural gas facilities. The agency would also set less restrictive standards for small oil and gas wells.

Trump said during Tuesday's rally in Lubbock for Texas Republican Senate candidate Ken Paxton that Biden's plan “crushed the small operators” with crippling regulations.

“I’m officially terminating Biden’s expensive and unnecessary methane regulations to save consumers and energy producers $45 billion in costs,” Trump said.

The loosening of the emissions rule comes as Trump and Republicans in Congress have been methodically dismantling climate policies enacted under former President Joe Biden. That's included the revocation of a scientific finding that was central to U.S. action on greenhouse gas emissions, lower fuel economy standards for vehicles and a move to repeal emission restrictions for coal and natural gas power plants.

Environmental groups said the latest rollback will let companies continue polluting the atmosphere with gas that could be captured and provide energy to millions of households.

Environmental Defense Fund President Fred Krupp said it gives a “free pass” to companies at the expense of American consumers.

“EPA should be fighting this waste, not making it easier,” he said.

Zeldin has said the methane rule would have cost $18 billion and was holding back the U.S. energy industry.

The Biden methane rule was announced by officials including former Vice President Kamala Harris during a 2023 U.N. climate conference in the United Arab Emirates.

Federal officials under Biden said it would prevent an estimated 58 million tons (52.6 million metric tonnes) of methane emissions by 2038 and reduce other pollutants that cause health problems.

By 2034, the rule was projected to yield $98 billion in benefits. That figure was derived by calculating the future “social costs” of greenhouse gas emissions on public health and the environment, an approach rejected by Trump's EPA.

While previous regulations focused only on new oil and gas wells in the U.S., the Biden rule regulated existing wells. Operators also would have needed to plug leaking methane from smaller wells that produce just 6% of the nation’s oil and gas while accounting for up to half of all methane emissions from oil and gas fields.

The final rule was published in 2024. The EPA last year imposed an 18-month delay to give companies time to meet new inspection requirements and other provisions.

The rule was crafted to be coordinated with a methane fee, approved in the 2022 climate law. The fee program would have levied a “waste emissions charge” of as much as $1,500 per metric ton of methane on energy producers that exceed a certain level of methane emissions.

The fee marked the first time the U.S. government directly imposed a fee, or tax, on greenhouse gas emissions. Congress repealed it weeks after Trump took office.

Officials also tried to rein in methane from oil and gas under former President Barack Obama, but that effort was scaled back during Trump's first term.

Houston energy company expands battery storage deal with Samsung

battery boost

Houston-based Alpha Omega Power, which develops, invests in and runs utility-scale battery energy storage systems, has signed a deal to add more storage capacity from a subsidiary of South Korean tech giant Samsung.

The latest deal adds 1 gigawatt-hour of storage capacity to Alpha Omega’s existing contract with Samsung SDI America, bringing total storage capacity to 1.5 gigawatts.

The Michigan-based Samsung subsidiary is manufacturing the systems’ cells and modules at a plant in Indiana, Alpha Omega said. Samsung SDI plans to deliver them by the end of this year.

“This second agreement strengthens our domestic supply chain supporting the next generation of energy infrastructure,” Paul Choi, CEO of Alpha Omega, said in a press release.

Houston-based Fengate Asset Management owns Alpha Omega. In 2023, they formed a partnership to build, acquire, and operate utility-scale battery energy storage projects in the U.S. Their 200-megawatt Vertus battery facility in Galveston County came online this month.

Alpha Omega plans to use the Samsung SDI systems to improve grid reliability and meet greater demand for power in markets served by the Electric Reliability Council of Texas (ERCOT) and the Salt Lake City-based Western Electricity Coordinating Council.

ERCOT covers 90 percent of power customers in Texas. The Western Interconnection grid covers all or part of 14 states, as well as parts of Canada and Mexico.

Samsung SDI is the only non-Chinese supplier of rigid-metal “prismatic” energy storage batteries in North America, according to Alpha Omega.

“With strong durability and fire safety compared with pouch-type batteries, its prismatic batteries have helped the company meet the stringent requirements of U.S. energy companies,” Alpha Omega said.

The Samsung Battery Box 1.7 equipment being purchased by Alpha Omega offers AI-powered algorithms and 25 years of continuous use, along with greater energy density than its predecessor. It also features the ability to directly inject fire-extinguishing agents on a module-by-module basis.
