Our Partnership with X-Energy

Centrica has partnered with X-energy to bring advanced nuclear technology to the UK, marking a major step forward in the country's clean energy transition. 

Through a Joint Development Agreement (JDA), announced in September 2025, the partnership plans to deploy X-energy's Xe-100 Advanced Modular Reactors, with Centrica and EDF’s Hartlepool site identified as the preferred location for the first project. The fleet will add up to 6 gigawatts of new nuclear capacity, delivering cutting edge clean, secure and affordable power while mobilising significant investment, skills and growth across the domestic supply chain. 

At Hartlepool alone, a potential 12-reactor deployment could generate 960 megawatts of low-carbon electricity – enough to power around 1.5 million homes. It would also create thousands of high-quality construction jobs and hundreds of long-term roles for decades of operation.

Working closely with Government, regulators and partners, Centrica and X-energy are helping make advanced nuclear a cornerstone of a resilient and sustainable UK energy system.

These UK projects will build on experience from two Xe-100 developments already underway in the United States – one in Texas with the US Government and Dow, and another in Washington State with Energy Northwest and Amazon.
