LONDON, September 15, 2025 – Centrica plc (“Centrica”) and X-Energy, LLC (“X-energy”), a wholly-owned subsidiary of X-Energy Reactor Company, LLC, today announced their entry into a Joint Development Agreement (“JDA”) to deploy X-energy’s Xe-100 Advanced Modular Reactors (“AMR”) in the United Kingdom. The companies have identified EDF and Centrica’s Hartlepool site as the preferred first site for a planned U.K. fleet of up to 6 gigawatts.

The agreement represents the first stage in a new trans-Atlantic alliance which could ultimately mobilize at least $54 billion in economic value to bring clean, safe and affordable power to thousands of homes and industries across the country and substantive work for the domestic and global supply chain. 

A 12-unit Xe-100 deployment at Hartlepool could add up to 960 megawatts (“MW”) of new capacity, enough clean power for 1.5 million homes and over $15 billion in lifetime economic value. It would be developed at a site adjacent to Hartlepool’s existing nuclear power station which is currently scheduled to cease generating electricity in 2028. Following its decommissioning, new reactors would accelerate opportunities for the site and its skilled workforce. The site is already designated for new nuclear under the Government’s National Policy Statement and a new plant would also play a critical role in generating high-temperature heat that could support Teesside’s heavy industries.

Centrica will provide initial project capital for development with the goal of initiating full-scale activities in 2026. Subject to regulatory approval, the first electricity generation would be expected in the mid-2030s. Centrica and X-energy are already in discussions with additional potential equity partners, as well as leading global engineering and construction companies, with the goal of establishing a UK-based development company to develop this first and subsequent projects.

“Our partnership with Centrica represents a commitment to bring X-energy's industry-leading advanced nuclear technology to the U.K. at scale. Together, we aim to build a fleet that has the ability to reliably deliver clean power, strengthen energy security, and grow the trans-Atlantic economy for decades to come. We believe Hartlepool is the right place to begin this journey, with an established industry and a base of professionals and services who can help drive the next generation of nuclear forward.”

In 2021 the U.K.’s Department of Energy Security and Net Zero (DESNZ) identified High-Temperature Gas-cooled Reactors (HTGRs) as the most promising advanced technology for demonstration. In 2025 X-energy and Cavendish Nuclear completed a number of year-long assessments, co-funded by DESNZ’s ‘Future Nuclear Enabling Fund’, to support the commercial deployment of Xe-100s in the U.K.  Discussions are now underway with Government regarding the “route to market” in the UK, consistent with the principles set out in June for supporting privately led projects. The Government’s ongoing work to create a clear and credible pathway is instrumental in making the UK an attractive destination for investment in advanced modular reactors. Support for initial projects, and those that follow, will be decisive in unlocking the full potential of advanced nuclear for Britain’s energy future.

U.K. Secretary of State for Energy Security and Net Zero Ed Miliband said:

“This cross-Atlantic partnership demonstrates the transformative potential for the British people of US and UK businesses joining forces, with X-Energy and Centrica’s planned first project alone having the potential to create up to 2,500 good, skilled jobs, add £12 billion in economic value and generate enough energy to power 1.5 million homes. By working with the US, we will reap the benefits of this golden age of nuclear, powering British homes with clean, homegrown energy, delivering well-paid skilled jobs and getting energy bills down for good.”

United States Secretary of Energy Chris Wright said:
“With President Trump’s leadership, the United States is ushering in a true nuclear renaissance – harnessing the power of commercial nuclear to meet rising energy demand and fuel the AI revolution. Meeting this demand will require strong partnerships with our allies around the world and robust collaboration with private sector innovators. Today’s commercial deals set up a framework to unleash commercial access in both the U.S. and UK, enhancing global energy security, strengthening U.S. energy dominance, and securing nuclear supply chains across the Atlantic.”

MIDLAND, Michigan and ROCKVILLE, Maryland – March 31, 2025 – Dow (NYSE: DOW) and X-Energy Reactor Company, LLC (“X-energy”) announced the submission of a construction permit application to the Nuclear Regulatory Commission (“NRC”) for a proposed advanced nuclear project in Seadrift, Texas. 

Dow’s proposed advanced small modular reactor (“SMR”) project is being developed by its wholly-owned subsidiary, Long Mott Energy LLC. The project is focused on providing Dow’s UCC Seadrift Operations manufacturing site (“Seadrift” or the “site”) with safe, reliable, and clean power and industrial steam replacing existing energy and steam assets that are near end-of-life. The project is supported by the U.S. Department of Energy’s (DOE) Advanced Reactor Demonstration Program (“ARDP”) which is designed to accelerate the deployment of advanced reactors through cost-shared partnerships with U.S. industry. 

Since 2018, X-energy, and subsequently Dow, have worked with the NRC through extensive pre-application engagements to demonstrate the unparalleled safety profile of the Xe-100 advanced SMR through its advanced fuel design, passive safety features, and state-of-the-art analysis techniques. This has culminated in a comprehensive application submittal that exceeds NRC regulations for the protection of public health and safety, as well as the environment, with substantial safety features. 

Approval of the construction permit is an important step forward that could take up to 30 months. Once the permit is received and upon Dow confirming the ability to deliver the project while achieving its financial return targets, construction could begin. Dow expects the cost of energy ‐ net of all subsidies ‐ to be competitive with other alternatives for firm, clean energy.   

“This is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the U.S.,” said Edward Stones, business vice president, Energy & Climate, Dow. “We look forward to engaging with the NRC, DOE, our business partners and the community throughout the application process.”

“The construction permit application is a critical step to deliver on the vision of Congress and DOE to position the U.S. at the forefront of commercializing advanced reactor technology,” said J. Clay Sell, chief executive officer of X-energy. “Together with our world-class partner, Dow, we will demonstrate how the technology deployed at Seadrift, Texas, can be quickly and efficiently replicated to meet incredible power demand growth across America.” 

The proposed project could begin construction later this decade and start up early next decade. The nuclear power and steam assets would eliminate most Scope 1 and 2 emissions at the site and ensure the site remains competitively advantaged for the life of the facility. 

X-energy was selected by the DOE in 2020 to develop, license, and build an operational Xe-100 advanced SMR and TRISO-X fuel fabrication facility. Since that award, X-energy has completed the engineering and preliminary design of the nuclear reactor, has begun development and licensing of a fuel fabrication facility in Oak Ridge, Tennessee, and has secured approximately $1.1 billion in private capital to commercialize its technology. Once complete, Long Mott Generating Station is expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.

Dow’s Seadrift site covers 4,700 acres and manufactures more than 4 billion pounds of materials per year used across a wide variety of applications including food packaging and preservation, footwear, wire and cable insulation, solar cell membranes, and packaging for medical and pharmaceutical products.
