SGE unveils plans for 4.2GW UK Small Modular Reactor fleet

 

• Programme of 14 Small Modular Nuclear Reactors could accelerate UK new nuclear and power almost eight million UK homes

• Project represents Britain's largest privately-led nuclear investment

 SGE, a European Small Modular Reactor (SMR) development and investment platform, yesterday announced its plans to build fourteen GE Vernova Hitachi BWRX-300 Small Modular Reactors on three sites in the UK. The deployment team includes SGE, GE Vernova Hitachi Nuclear Energy, Samsung C&T, Laing O'Rourke, Aecon Group Inc., Google Cloud, Fermi Development, Etara and an experienced nuclear operator.

The company has submitted an application under the UK's Advanced Nuclear Framework (ANF) to develop a combined 4.2GW fleet which could deliver enough clean power for 11% of UK power demand or equivalent to an estimated almost eight million homes for at least sixty years. To support this ambition, SGE has established SGE SMR UK Limited as its dedicated UK-based project vehicle.

SGE's proposal reflects a fleet-based development model, centred on repeatable deployment at scale. The project is targeting three multi-unit sites, the first to host six BWRX-300 units, with two further sites to follow in quick succession. In total, the programme represents a significant addition to the UK's future nuclear capacity and supports the country's long-term energy security, clean power and industrial growth ambitions.

The UK project builds on significant regulatory groundwork already in place for the BWRX-300, a tenth generation, proven technology that draws on the experience of 67 successful reactor deployments. The technology is under licensed construction in Canada and is on schedule to be the first SMR to operate in the OECD. In December 2025, the BWRX-300 successfully completed Step 2 of the UK's Generic Design Assessment.

The partnership brings together proven reactor technology, significant project development experience, industrial capability and supply chain expertise and financing structure experience to support the deployment of the BWRX-300 in the UK. SGE is presenting a privately financed, commercially-led investment, supported by strong delivery partners. SGE plans to deploy under a Contract for Difference framework with National Wealth Fund engagement, meaning there will be no charges to consumers prior to operations.
