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.

Houston energy leaders form new coalition to improve Texas power grid

grid tech

A Houston-based coalition that launched this month aims to educate Texas officials about technology designed to shore up the state’s power grid.

The public-private Texas Reliability Coalition says it will promote utility-scale microgrid technology geared toward strengthening the resilience and reliability of the Texas power grid, particularly during extreme weather.

A utility-operated microgrid is a group of interconnected power loads and distributed energy sources that can operate in tandem with or apart from regular power grids, such as the grid run by the Electric Reliability Council of Texas (ERCOT). Legislation passed in 2023 enables the use of utility-scale microgrid technology in Texas’ deregulated energy market, according to the coalition.

John Elder, executive director of the coalition, says that with the legal framework now in place, the Public Utility Commission of Texas and ERCOT need to create rules to establish the Texas marketplace for microgrid technology. The goal, he says, is to “take the Texas grid from good to great” by installing microgrid technology, improving the infrastructure, and strengthening the system — all targeted toward meeting power needs during extreme weather and amid growing demand.

Houston-based CenterPoint Energy will test the utility-scale microgrid technology being promoted by the coalition. In a January 31 filing with the Public Utility Commission, CenterPoint says microgrid technology will be featured in a $36.5 million pilot program that’ll set up an estimated three to five microgrids in the company’s service area. The pilot program is slated to last from 2026 to 2028.

In the public affairs arena, five Houston executives are leading the new reliability commission’s microgrid initiative.

Elder, one of the coalition’s founding members, is president and CEO of Houston-based Acclaim Energy. Other founders include Ember Real Estate Investment & Development, Park Eight Development, and PowerSecure. Ember and Park Eight are based in Houston. Durham, North Carolina-based PowerSecure, which produces microgrid technology, is a subsidiary of energy provider Southern Co.

Aside from Elder, members of the coalition’s board are:

  • Stewart Black, board secretary of the coalition and vice president of Acclaim Energy’s midstream division
  • Todd Burrer, president of municipal utility districts at Inframark.
  • Harry Masterson, managing principal of Ember
  • Martin Narendorf, former vice president at CenterPoint Energy.

New survey reveals concerns over AI data center growth in Houston

data findings

A new report out of the University of Houston shows that area residents remain wary of the long-term effects of operating data centers.

The recent survey from the University of Houston’s latest SPACE City Panel, conducted by the Center for Public Policy at the Hobby School of Public Affairs, shows that while 85 percent of Houston-area residents use AI, nearly 63 percent oppose the construction of AI data centers within 1 mile of their homes.

Respondents’ concerns centered around data centers’ high energy demand and the area’s power grid reliability. According to the survey, 32 percent of residents who oppose local data center projects would be more likely to support the centers if they relied on renewable energy over fossil fuels.

“Respondents understand that AI can bring economic and educational benefits, but they are also concerned about the physical infrastructure needed to fuel AI, especially data centers,” Soran Mohtadi, post-doctoral fellow at the Hobby School and a researcher on the report, said in a news release. “This physical infrastructure demands more electricity and water, leading to environmental impacts.”

Experts estimate that 6.5 gigawatts of data center capacity will be added to the Texas grid by 2030. And Houston’s data center capacity is predicted to more than double by 2028.

The Electric Reliability Council of Texas also projects electricity demand could reach 218 gigawatts by 2031, which would be more than double the record peak set in August 2023. Data centers are expected to account for 86 gigawatts of that new demand.

Survey respondents also said they are concerned about the state's future water supply, given the large amounts of water that data centers need to stay cool.

In terms of who’s responsible for that issue, 57.6 percent of respondents said they put the onus on Texas lawmakers, while 31.5 percent say tech companies should be responsible.

Additionally, more than 75 percent of respondents believed that data center developers and technology companies—not residents—should bear the cost of infrastructure upgrades to support data centers.

“Every decision legislators make has implications on residents’ everyday lives and local infrastructure now and in the future,” Maria P. Perez Arguelles, lead researcher on the report and research assistant professor at the Hobby School, added in the news release. “This issue is going to become more important in years to come, so this is just the beginning.”

American Airlines and Google ink record-breaking deal for cleaner jet fuel

SAF DEAL

Fort Worth-based American Airlines has sealed a record-breaking deal with tech giant Google to bolster the use of cleaner jet fuel.

The deal involves Google’s purchase of sustainable aviation fuel certificates tied to fuel that American will use at Chicago O’Hare International Airport, one of the airline’s hubs. These certificates enable companies like Google to pay for the environmental benefits of sustainable jet fuel without actually using the fuel.

American and Google say this is the largest publicly announced certificate deal between an airline and a corporate customer.

Google says environmental gains from the certificates will help it cut emissions from employees’ business travel.

The agreement covers 35 million gallons of sustainable aviation fuel over three years, resulting in a nearly 300,000 metric tons of carbon dioxide equivalent emissions. American has agreed to buy the fuel from San Antonio-based Valero.

“Our industry-leading agreement with Google is a critical step forward in reducing emissions from our operations,” Jill Blickstein, American’s chief sustainability officer, said in a news release. “By working with leaders like Google who share our commitment to innovation, we’re helping to grow demand for [cleaner jet fuel] and support the development of a stronger, more resilient market.”

Sustainable aviation fuel can reduce emissions by up to 80 percent compared with traditional jet fuel. It is made from feedstocks, like waste oil and fats, or it can be produced synthetically using captured carbon dioxide and renewable electricity.

The aviation industry accounts for about 2.5 percent of carbon dioxide emissions around the world, according to the International Energy Agency.

CenterPoint reports grid resilience updates as hurricane season begins

hurricane readiness

As hurricane season descends upon the region, CenterPoint Energy has shared the latest update on its Greater Houston Resiliency Initiative (GHRI) that’s been working to make grid upgrades and introduce weather-related tech since 2024.

As of April 2026, CenterPoint had:

  • Replaced more than 65,000 poles with stronger storm-resistant infrastructure
  • Trimmed or cleared more than 10,000 miles of vegetation
  • Undergrounded more than 500 miles of power lines
  • Installed more than 600 automation devices
  • Installed more than 150 weather stations

In May, CenterPoint announced its new Community Progress Tracker, which helps residents track electronic infrastructure improvements. In terms of other technology, CenterPoint has announced its partnership with weather, wildfire and flood modeling software Technosylva. The software is expected to help CenterPoint track weather conditions in advance to better prepare crews.

CenterPoint has also added 150 weather stations to improve weather monitoring, conducted a full-scale hurricane response exercise involving more than 400 employees and completed more than 25,000 hours of FEMA training across more than 800 employees. The company opened a new year-round Emergency Operations Center to help coordinate with emergency response partners, local and state officials, and media during major weather events.

“We are proud of the progress made in 2025, which helped deliver more than 100 million fewer outage minutes when compared to 2024, and we are determined to make even more progress in 2026 as we work toward our defining goal: building the nation's most resilient coastal grid,” Nathan Brownell, CenterPoint's vice president of resilience and capital delivery, previously said in a news release.

According to the company, the GHRI aims to improve overall grid resiliency and reliability and to reduce outages for customers. CenterPoint projects its efforts can reduce customer outages by 150 million by the end of 2026.
