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.

Hertha Metals raises $133M Series A round, plans high-purity iron plant

cleaner steel

Conroe-based Hertha Metals has closed a $133.65 million Series A round that includes a $65 million equity investment from the Pentagon. The startup uses a one-step process to convert iron into molten steel or high-purity iron.

Khosla Ventures and Doerr Capital co-led the round, with participation from CEV, Pear Ventures, Gates Frontier, Niterra SUISO no MORI Fund, Toyota Ventures, and Siemens Financial Services.

The federal investment came from the U.S. Department of Defense’s Industrial Base Analysis and Sustainment program. The program aims to strengthen and modernize the U.S. Defense Industrial Base, a network that researches, designs, builds, and maintains military weapons, equipment, technology, and services.

The Series A funding will finance construction of Hertha Chalyx, a plant that will be capable of producing 10,000 metric tons of steel-grade and magnet-grade high-purity iron.

Hertha says Chalyx will provide U.S.-made material for manufacturers of rare-earth magnets. Today, China controls more than 90 percent of the global manufacturing of rare-earth magnets.

Rare-earth magnets can be found in fighter jets, smart bombs, submarines, satellites, drones and other military hardware. These magnets are also key components in electric vehicle motors, wind turbines, computer hard drives, smartphones, headphones, cordless tools and an array of other products.

“Every electric vehicle, aerospace platform, radar system, and data center depends on domestic iron and magnet feedstock suppliers,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

“Hertha Chalyx closes that gap,” she added. “We are building the supply chain this country needs, and we are doing it by providing a domestic cost-competitive option for manufacturers while unlocking safer and cleaner production.”

Hertha says Chalyx, alongside its Pi100 pilot project, will be the first modern-day “iron and steel innovation complex.” The startup expects to break ground on Chalyx this year.

Since its founding in 2022, Hertha has raised more than $150 million from investors.

Houston carbon removal company secures $35M in financing

national scale

Houston-based Vaulted Deep, a waste management and carbon removal company, has announced a major $35 million debt facility from Italian investment bank Mediobanca to support its national expansion.

U.K.-based market energy solutions CFP Energy arranged the deal, which is “the largest publicly disclosed U.S. commercial debt deal in durable carbon removal to be secured by long-term purchase contracts,” according to a news release from the companies.

The financing will support new waste disposal sites for Vaulted Deep and advancements of the company’s AI-enabled site development platform. The platform helps identify locations, navigate permitting and optimize injection operations. When candidates are looking for sites, the platform will pull from regulatory, geology and waste-supply data to assist, which Vaulted Deep says will help streamline the permitting process. After the site is operating, the platform helps control algorithms to maximize safe disposal capacity and monitor the process along the way.

"Waste operators across the country need new options as traditional disposal options become limited,” Julia Reichelstein, CEO and co-founder of Vaulted Deep, said in the release. “This financing lets us take on more projects and invest in the tools that help us evaluate and develop new sites faster. This is a meaningful milestone for Vaulted as we move into the next phase of building infrastructure at a much larger scale."

The deal is supported by Vaulted Deep's long-term waste service and carbon removal purchase contracts. The company says it delivered more than 20,000 tons of carbon removal to buyers in the first half of 2026, which is more than it delivered in all of 2025.

"By facilitating these types of transactions, we connect institutional capital with innovative climate technologies, helping accelerate the deployment of high-integrity carbon removal solutions,” Tyler Manchester, head of voluntary carbon for CFP Energy, added in the release. “It reflects growing investor confidence in these solutions, driven by rising demand from corporate buyers seeking permanent pathways to support net-zero commitments and long-term climate strategies."

Beyond the facility, Vaulted Deep has secured $48 million in equity financing in addition to its $8 million from the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

The company's well injection technology is used to store organic waste deep underground in stable geologic formations. In 2025, it inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.
