Balfour Beatty joins with Holtec to fuel the UK’s nuclear energy drive

19 December 2022


Balfour Beatty, the international infrastructure group, today announces that it has signed a memorandum of understanding with Holtec Britain, a subsidiary of Holtec International – a supplier of equipment and systems to the global energy industry and Hyundai Engineering and Construction (HDEC) – to support the planning advancement for the construction of Holtec’s SMR-160 pressurised light-water reactors in the UK.

Balfour Beatty will act as the main UK construction partner and collaborate with HDEC on the civil construction and installation of the Mechanical, Electrical and Heating, Ventilation and Cooling systems as well as the equipment required for Holtec International’s innovative SMR-160 reactors.

Holtec International is planning to start the UK regulatory acceptance process of its SMR-160 reactors in 2023, which, when granted, will enable the start of the construction of the first UK unit in as early as 2028.

Once approved, the SMR-160 power plant units are poised to play a key role in the delivery of the UK Government’s Energy Security Strategy, targeting five gigawatts of clean electricity to the National Grid by 2050.

Stephen Tarr, Chief Executive Officer for Transport, Energy & Power Major Projects at Balfour Beatty, said: “We look forward to working with Holtec International to drive forward clean energy solutions. Our partnership will build on our long-standing experience and expertise in delivering nuclear projects and will ultimately support the UK’s transition towards a Net Zero future.”  

Dr. Richard M. Springman, Senior Vice President of International Projects & Executive Committee Member of Holtec International said: “The United Kingdom is at a turning point as it navigates through this energy crisis. The decisions made today will impact how future generations in the UK live and work, and the viability of its economy as a whole.

“I believe it will need multiple, complementary nuclear power plant designs based on proven Pressurized Water Reactor (PWR) technology already operating in the United Kingdom to assure carbon-free energy security ten years from now; and we have to start now.”

This latest partnership bolsters Balfour Beatty’s commitment to addressing the growing demand for clean energy across the UK – further building on the company’s recent memorandum of understanding with Aker Solutions to deliver end-to-end design and construction solutions for the concrete floating and gravity-based UK offshore wind industry.
