Micro-nuclear technology developer Last Energy has announced plans to build 30 microreactors in Haskell County, Texas.
The initiative aims to serve data centre customers across the state, addressing the increasing power demand.

The company has secured control of the 200-acre site and intends to deliver energy through a combination of private wires and grid transmission.
The company has already applied for a grid connection with the Electric Reliability Council of Texas.
Following discussions with local stakeholders, Last Energy will apply for an early site permit from the US Nuclear Regulatory Commission.
The move is driven by the recent surge in demand from Texas-based data centre developers over the past year.
Last Energy founder and CEO Bret Kugelmass stated: “Texas is America’s undisputed energy leader, but skyrocketing population growth and data centre development is forcing policymakers, customers and energy providers to embrace new technologies.
“Nuclear power is the most effective way to meet Texas’ demand, but our solution — plug-and-play microreactors, designed for scaleability and siting flexibility — is the best way to meet it quickly. Texas is a state that recognises energy is a precondition for prosperity, and Last Energy is excited to contribute to that mission.”
Last Energy’s existing commercial agreements include the delivery of more than 80 microreactors across Europe, with half dedicated to data centres.
The Texas project will add 30 units to the company’s development capacity, supporting the expansion of its commercial pipeline in the US.
The project is expected to enhance grid capacity and meet data centre deployment projections.
Texas currently hosts 340 data centres, consuming almost 8GW of power, which accounts for 9% of the state’s electricity demand.
Texas Governor Greg Abbott said: “Texas is the energy capital of America, and we are working to be number one in advanced nuclear power. Last Energy’s microreactor project in Haskell County will help fulfil the state’s growing data centre 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.”
Last Energy’s PWR-20 microreactor is designed for mass-manufacturability, allowing scaleability based on user demand.
As a founding member of the Texas Nuclear Alliance, Last Energy aims to accelerate nuclear deployment across the state.
The company has secured its first full core load of fuel, scheduled for arrival in September 2026.
