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.

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Houston lawmaker may kill data center tax breaks due to $8B revenue loss

looking at the data

An influential Houston-area state senator is raising concerns about potentially billions of dollars in lost state revenue from tax breaks for Texas data centers—and is pondering legislation that would abolish the tax incentives.

Citing data from the state comptroller’s office, The Texas Tribune reports the state stands to lose nearly $8 billion in revenue from 2026 to 2030 due to sales tax and use tax exemptions for data centers. During the state’s 2025 fiscal year, which ended on Aug. 31, these tax exemptions caused Texas to lose a little over $1 billion, up from an earlier estimate of $130 million.

“These new numbers are extremely concerning, and I will say they’re unsustainable,” Republican state Sen. Joan Huffman, chairwoman of the state Senate Finance Committee, tells The Texas Tribune. “I plan to look at filing legislation to either repeal the exemption or take a very close look at it and see.”

Texas on track to be No. 1 data center market in U.S.

Scrutiny of the tax breaks comes amid an explosion of data center development in Texas, where data provider Aterio identifies nearly 1,000 centers that are operating, under construction or planned.

A report issued in January by Bloom Energy says the state is poised to become the No. 1 U.S. market for data centers within three years. By 2028, according to the report, Texas is projected to exceed 40 gigawatts of data center capacity—representing nearly 30 percent of total U.S. demand.

Among companies benefiting from the data center boom are:

  • Tech titans like Apple, Google, Meta Platforms, and Microsoft, which are spending billions of dollars to build data centers in Texas.
  • Spring-based ExxonMobil and Houston-based Chevron, two oil and energy giants that are developing natural gas plants to supply power for data centers.
  • Houston-based energy technology company Baker Hughes, which is collaborating with Google Cloud to develop AI-enabled power optimization and sustainability software for data centers.
  • DataBank, Data Foundry, Equinix, Digital Realty, Lumen Technologies, and IBM, all of which operate data centers in the Houston area.

The Texas Legislature will begin debating tax breaks for data centers in July, when Huffman’s Senate Finance Committee meets for an interim hearing before the 2027 legislative session, according to the Tribune.

Data center industry defends tax breaks

Leaders in the data center industry warn that watering down or halting the tax breaks could slow down or even end Texas’ ascent in the data center sector.

A 2025 report commissioned by the Data Center Coalition found that in 2024, data centers provided more than $1.6 billion in state tax revenue and almost $1.6 billion in local tax revenue in Texas. Over the next several years, according to the report, planned development of data centers in the Lone Star State could generate almost $3.8 billion in state tax revenue and more than $4.9 billion in local tax revenue.

In 2024, the Houston area had 8.1 million gross square feet of data centers, with the properties’ real estate investments sitting at $10 billion, according to the report. That year, data centers in the region produced a little over $700 million in state and local tax revenue. About 60 data centers operate in the Houston area.

Watchdog group warns of tax breaks’ danger to state budgets

On the other side of the debate over tax breaks for data centers, a report released last year by Good Jobs First, a nonprofit, nonpartisan watchdog group that tracks economic development incentives, decries the tax breaks as dangerous to state budgets.

“We know of no other form of state spending that is so out of control. Therefore, we recommend that states cancel their data center tax exemptions,” says Good Jobs research analyst Kasia Tarczynska, co-author of the report. “Shy of that, states should amend … legislation to cap how much any facility and company can avoid paying in taxes each year.”
