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.

Energy giant Shell lists Houston HQ for sale for $325 million

asset offload

Energy giant Shell has put its U.S. headquarters in Houston’s Energy Corridor on the market and is exploring the sale of its U.S. chemical business.

Green Street News reported Shell just listed its longtime Energy Corridor campus at 150 N. Dairy Ashford Road. The asking price is $325 million, The Real Deal reported. Shell plans to lease back half of the nearly 1.5 million-square-foot Woodcreek campus for 15 years.

A sale-leaseback deal could transform the 43.6-acre campus into a multitenant hub, CoStar News reported.

“Houston is a critical hub for Shell globally and the headquarters of our U.S. businesses,” a Shell spokesperson told the Houston Business Journal. “We remain committed to Houston and are evaluating opportunities to optimize our Woodcreek campus as part of our ongoing review of workplace needs while maintaining a strong presence in the city.”

Shell occupied its first building at the West Houston campus in 1980. The company employs more than 6,000 people in Texas.

Shell is one of the highest-profile businesses occupying space in the Energy Corridor. It’s home to 67,000 workers, more than 27 million square feet of office and mixed-use space, and 3.8 million square feet of retail and restaurant space.

Shell considers $8B sale of chemical business

As the company seeks to unload its Woodcreek campus, The Financial Times reported Shell is looking into selling its U.S. chemical business. The price tag: $8 billion.

Potential buyers include Spring-based ExxonMobil and Houston-based LyondellBasell.

Shell operates four chemical plants in Texas, Louisiana and Pennsylvania, producing an array of chemicals for use in plastics, detergents and pharmaceuticals.

Shell CEO Wael Sawan said last year that the company had spent $45 billion in capital “that is underperforming for us,” split between its chemical business and renewable energy arm.

Shell also agreed to sell its solar and wind power business in India this summer. Read more here.

Trump continues to champion data center growth despite rising voter concerns

Data Development

President Donald Trump, speaking alongside cryptocurrency leaders at the White House, made a statement that Republican and Democratic candidates alike wouldn't touch.

“If I were the mayor of a town or the governor of a state, and I had a chance to get a big plant in, an AI plant or a data center,” Trump said, “I would absolutely want it because the jobs are enormous and the money paid, the taxes paid, are just enormous.”

It's not the kind of message anyone is using in competitive midterm races.

The race to build data centers, which power artificial intelligence and cloud computing, has run aground amid frustration from voters who don't want to live near the massive warehouse campuses. Even the Senate Republicans' campaign arm warned that anger over data centers — some of which dwarf football stadiums and use more energy than small cities — could cost them a seat.

Opposition stretches across the political spectrum because of fears that the behemoths will jack up electricity bills, drain people's water wells, create unhealthy amounts of air and noise pollution and forever change a community's character — all while getting lucrative tax breaks from states competing for their business.

Trump has framed data centers as a necessary component of a top national and economic security priority: winning the AI race against China. However, he also has acknowledged concern over rising electricity bills, previously saying “it’s only fair” for the companies to shoulder their costs.

He also suggested this week that data centers need “a little public relations help.” In recent months, he has gotten tech giants to sign a voluntary pledge to shield U.S. consumers from higher utility bills from data centers, even as he pushes to streamline the process for companies and utilities to build their own power plants.

But building power plants doesn't happen overnight, and the immediate political reality for candidates across the country is far different.

“It is yet another dimension in which the White House appears tone deaf — tone deaf at best and indifferent to the interest of other Republican candidates at worst,” said James Henson, the director of the Texas Politics Project at the University of Texas, Austin, a nonpartisan research organization.

Republican committee issues warning over data centers in Ohio

Statewide candidates from Nevada to Pennsylvania, both Republican and Democratic, are weaponizing data centers against their opponents, and candidates who absorb those attacks are subsequently trying to distance themselves from them.

In Ohio, a data center hot spot with closely contested races for governor and U.S. Senate, the National Republican Senatorial Committee warned in a memo Tuesday that Sen. Jon Husted is vulnerable to losing his seat because of the centers.

Democratic nominee Sherrod Brown is airing attack ads against Husted that call him the “face of data centers in Ohio” as people gather signatures for a statewide referendum to ban their construction.

The Republican memo said it's been a “sleeper issue for the entire election cycle.”

“Brown is using it because it works,” the NRSC said. “More than any other thing in this race, data centers are the anchor hanging around Husted’s neck. If he loses and data centers get the blame, politicians across the country will take notice — and they will not go near the next one.”

The memo suggested voters may balk at Democratic candidates who want to stop data center construction altogether in favor of a Republican candidate who only wants data centers built if a community approves it in a local vote and it pays for its own power, water and other utilities.

Most registered voters oppose building a data center in their area, according to a July Fox News poll.

Still, the issue falls behind other voter concerns, such as cost of living, as November looms. A Quinnipiac Poll conducted in June asked voters what issues were important in deciding who to vote for in U.S. House elections, and about 4 in 10 mentioned AI data centers.

Trump’s statement already put to use in Nevada race

In Nevada, Democrat Aaron Ford quickly tied Trump’s statement to Republican Gov. Joe Lombardo, characterizing them as being in “lockstep on data centers.”

In a statement, Ford said Trump and Lombardo are “Nevada data centers’ biggest cheerleaders” who “only care about catering to their ‘billionaire friends’ while Nevadans pay the price.”

Ford this week unveiled a policy platform in which he said he would halt new state tax breaks for data centers — he estimated them at $200 million currently — while auditing existing projects to ensure they are delivering on promises. He also said he would ensure data centers pay for their electricity needs, do not deplete Nevada’s water supply and help local governments negotiate strong benefits agreements with developers.

Texas' governor changed course and got a jab from Trump

Texas Gov. Greg Abbott, who last November celebrated Google’s announcement of a $40 billion investment there by calling the state “the epicenter of AI development,” is under attack from his Democratic challenger, Gina Hinojosa, over his pursuit of data center development.

Abbott has since changed course by promising tougher action, such as removing the state’s sales tax exemption and holding up projects to review their energy usage.

Trump criticized the shift, saying “I think it's a mistake” in a recent interview with Punchbowl News.

Asked about Trump's support for data centers, Abbott's office said the governor's “top priority is to protect Texans’ safety and quality of life and ensure the integrity of our power grid and water supply.”

“Simply put, Texans must come first,” Abbott's office said.

Data centers complicated Wisconsin governor race

While Trump embraces data centers, even some of his allies are using them for political attacks. U.S. Rep. Tom Tiffany, running for Wisconsin governor, released a TV ad this week branding his Democratic opponent as “Data Center David Crowley.”

The ad includes a clip of Crowley saying Wisconsin could become the “AI and data hub not only for the entire country, but for the entire globe.”

Crowley has said local communities must have veto authority while also calling data centers a part of the modern economy that could bring significant economic benefits to the state.

Tiffany, who Trump has endorsed, has also said positive things about data centers. In January, Tiffany called data centers “exciting new technology,” in an interview with PBS Wisconsin. And last December, he voted for a bipartisan bill known as the SPEED Act, which is designed to accelerate construction of new AI infrastructure projects like data centers. It hasn't passed the Senate.

Neither Tiffany nor Crowley support a moratorium on new data center construction.

Tiffany has called for repealing the state tax incentive for data centers, while Crowley has not. They both have called for stricter regulation.

Crowley, at an event Wednesday where he received the endorsement of the environmental group Clean Wisconsin, downplayed the attacks Tiffany has made against his data center position.

“He’s getting very good at saying one thing and doing something different,” Crowley said, pointing to Tiffany’s votes in support of the SPEED Act.

“What Congressman Tom Tiffany’s doing is lying because he’s trying to run away from his record in Congress,” Crowley said.

Houston startup wins Space Force contract to advance quantum energy generator

quantum contract

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.
