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.

Houston-based Syzygy Plasmonics has secured a six-year official offtake agreement for the entire production volume of its first commercial-scale biogas-to-sustainable aviation fuel project in Uruguay, known as NovaSAF-1.

SP Developments Uruguay S.A., a subsidiary of Syzygy, entered into the agreement with Singapore-based commodity company Trafigura, according to a news release. There is also an option for Trafigura to purchase additional volumes from future Syzygy projects.

The first deliveries from the landmark SAF facility are expected in 2028.

“This agreement marks a critical step in our journey toward commercial-scale impact and disrupting the SAF market,” Trevor Best, CEO of Syzygy Plasmonics, said in the news release. “With a signed offtake agreement from a global leader like Trafigura, and after having successfully completed FEED engineering in December, we're now ready to secure financing for the construction of NovaSAF-1 and move our technology from potential into production."

The NovaSAF-1 project will be located in Durazno, Uruguay. The facility will be the world's first electrified biogas-to-SAF facility producing renewable and advanced compliant SAF. Syzygy estimates that the project will produce over 350,000 gallons of SAF annually. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

It’s backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago. It will also work with Houston-based Velocys, which will provide Fischer-Tropsch technology for the project. Fischer-Tropsch technology converts synthesis gas into liquid hydrocarbons, which is key for producing synthetic fuels like SAF.
