Energy co. to build 30 micro-nuclear reactors in Texas to meet rising demand

A Washington, D.C.-based developer of micro-nuclear technology plans to build 30 micro-nuclear reactors near Abilene to address the rising demand for electricity to operate data centers across Texas.

The company, Last Energy, is seeking permission from the Electric Reliability Council of Texas (ERCOT) and the U.S. Nuclear Regulatory Commission to build the microreactors on a more than 200-acre site in Haskell County, about 60 miles north of Abilene.

The privately financed microreactors are expected to go online within roughly two years. They would be connected to ERCOT’s power grid, which serves the bulk of Texas.

“Texas is America’s undisputed energy leader, but skyrocketing population growth and data center development is forcing policymakers, customers, and energy providers to embrace new technologies,” says Bret Kugelmass, founder and CEO of Last Energy.

“Nuclear power is the most effective way to meet Texas’ demand, but our solution—plug-and-play microreactors, designed for scalability and siting flexibility—is the best way to meet it quickly,” Kugelmass adds. “Texas is a state that recognizes energy is a precondition for prosperity, and Last Energy is excited to contribute to that mission.”

Texas is home to more than 340 data centers, according to Perceptive Power Infrastructure. These centers consume nearly 8 gigawatts of power and make up 9 percent of the state’s power demand.

Data centers are one of the most energy-intensive building types, says to the U.S. Department of Energy, and account for approximately 2 percent of the total U.S. electricity use.

Microreactors are 100 to 1,000 times smaller than conventional nuclear reactors, according to the Idaho National Laboratory. Yet each Last Energy microreactor can produce 20 megawatts of thermal energy.

Before announcing the 30 proposed microreactors to be located near Abilene, Last Energy built two full-scale prototypes in Texas in tandem with manufacturing partners. The company has also held demonstration events in Texas, including at CERAWeek 2024 in Houston. Last Energy, founded in 2019, is a founding member of the Texas Nuclear Alliance.

“Texas is the energy capital of America, and we are working to be No. 1 in advanced nuclear power,” Governor Greg Abbott said in a statement. “Last Energy’s microreactor project in Haskell County will help fulfill the state’s growing data center demand. Texas must become a national leader in advanced nuclear energy. By working together with industry leaders like Last Energy, we will usher in a nuclear power renaissance in the United States.”

Nuclear energy is not a major source of power in Texas. In 2023, the state’s two nuclear power plants generated about 7% of the state’s electricity, according to the U.S. Energy Information Administration. Texas gains most of its electricity from natural gas, coal, wind, and solar.

With an initial investment of $2 billion, AI chip manufacturer NVIDIA just acquired a 20 percent stake in The Woodlands-based Lancium, which develops large-scale campuses that combine AI data centers and onsite power supplies.

Lancium recently announced the investment but didn’t disclose the dollar amount. The Information news website reported NVIDIA’s investment totaled $2 billion, with the possibility of an additional $1 billion if Lancium achieves certain milestones.

Dealroom.co calls NVIDIA’s investment a “form of supply-chain insurance.”

NVIDIA “is gaining exposure to the scarce physical assets that determine whether its chips can be deployed,” Dealroom.co says. “The move makes Nvidia look less like a pure chip company and more like an allocator of infrastructure capacity.”

Investment precedes possible IPO in 2027

Thanks to NVIDIA’s cash infusion, Lancium and its portfolio of land and power connections carry an enterprise value of about $10 billion, according to The Information.

The investment should enable Lancium to expand as it explores a potential IPO next year, The Information reported.

Neither Lancium nor NVIDIA is responding to requests for comment about the deal.

Lancium’s marquee project is a 1,000-acre data center and power generation campus in West Texas for the $500 billion Stargate initiative. Stargate, a joint venture comprising MGX, OpenAI, Oracle and SoftBank, is building data centers equipped to handle AI-level workloads.

“Epicenter of energy and AI infrastructure”

Founded in 2017, Lancium has 4 gigawatts of leased capacity and a more than 15-gigawatt development pipeline. In 2024, Blackstone Energy Transition Partners invested about $500 million in Lancium, giving Blackstone a roughly 50 percent stake.

“This partnership with NVIDIA is a strong testament to Lancium’s position at the epicenter of energy and AI infrastructure … . We look forward to continuing to partner with these leading companies to help power the next generation of AI innovation,” Bilal Khan, senior managing director at Blackstone, said in a release.

Through the NVIDIA partnership, Lancium’s data center and power generation campuses will use the tech company’s “AI factory” platform, including software, computing, and networking capabilities. This will give NVIDIA customers and partners access to power capacity that supports heavy AI workloads.

“We have spent years assembling the power, the land, and the infrastructure expertise needed to deliver AI data center capacity at a scale the world has never seen,” Michael McNamara, co-founder and CEO of Lancium, said in the release.

“Partnering with NVIDIA — the definitive technology platform for AI computing — ensures that every campus in our portfolio will be deployed with the industry’s most advanced technology and that NVIDIA’s customers will have access to the capacity they need to compete and lead in the AI era.”
