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.

Houston energy pioneer elected to National Academy of Sciences leadership

top honor

Naomi Halas, a Rice University professor and co-founder of Syzygy Plasmonics, was elected to the Council of the National Academy of Sciences this month.

The council sets priorities for the nonprofit organization, which advises the federal government on scientific and technical matters. Halas will serve a three-year term on the council, beginning July 1.

“The council’s work is focused on the academy’s national leadership and governance,” Halas said in a news release. “It plays an important role in helping set initiatives and priorities for the scientific community, and in supporting the conditions that allow science to move forward in meaningful ways.”

Halas is best known for her pioneering work in nanophotonics and plasmonics. She helped develop nanoshells, or metal-coated nanoparticles that capture light energy, which have led to innovations in renewable energy, cancer therapy and water purification.

Halas co-founded Syzygy Plasmonics with frequent collaborator and fellow Rice professor Peter Nordlander. The company is developing low-cost, light-driven, all-electric chemical reactors for the sustainable production of hydrogen fuel. It was named to Fast Company's energy innovation list last year.

Syzygy Plasmonics is developing its first commercial-scale biogas-to-sustainable aviation fuel project in Uruguay, known as NovaSAF-1. It secured a six-year offtake agreement for the entire production from the project with Singapore-based commodity company Trafigura this month.

Halas was first elected to become a member of the NAS in 2013, and was shortly after named to the National Academy of Engineering in 2014—making her one of the few scientists to hold both distinctions. She received the Benjamin Franklin Medal in Chemistry last year. Many scientists who have received the award have gone on to win Nobel prizes.

She is also the co-founder of Nanospectra Biosciences and a member of the National Academy of Inventors, the American Academy of Arts and Sciences, and the Royal Danish Academy of Science and Letters. She holds more than 25 patents, according to Rice.

Houston startup launches groundbreaking mineral hydrogen pilot

pilot project

Houston climatech company Vema Hydrogen recently completed drilling its first two pilot wells in Quebec for its Engineered Mineral Hydrogen (EMH) pilot. The company says the project is the first EMH pilot of its kind.

Vema’s EMH technology produces low-cost, high-purity hydrogen from subsurface rock formations. It has the capacity to support e-fuel and clean mobility industries and the shipping and air transport markets. The pilot project is the first field deployment of the company’s technology.
