Regulatory assessment

Great British Energy - Nuclear

In 2026, Rolls-Royce SMR was selected by Great British Energy – Nuclear as the preferred technology in the UK’s Small Modular Reactor programme, following a rigorous two-year assessment process. The landmark decision means the next generation of UK nuclear power stations will be designed and built by a British company, supporting thousands of highly skilled jobs, strengthening the UK supply chain and driving long-term economic growth.

Building on this momentum, Rolls-Royce SMR and Great British Energy – Nuclear signed a contract to begin work on deploying the UK’s first Small Modular Reactors at Gwyndod on Ynys Môn, North Wales. The agreement enables site-specific development activities to start and is a major step towards delivering clean, secure and reliable electricity for millions of UK homes.

Rolls-Royce SMR is the only SMR developer with multiple deployment commitments across Europe. Together with our customers, partners and supply chain, we are turning ambition into action, bringing a new generation of nuclear power to market and helping to deliver a more secure, sustainable energy future.

Chris Cholerton, Chief Executive of Rolls-Royce SMR, commented:

“This success is testament to our incredible team which has developed a world-leading technology and worked tirelessly over the last two years to ensure we could provide a winning tender to GBE-N.

“As well as delivering affordable, clean energy to support our nation’s energy independence – deploying three of our units will drive domestic growth by creating thousands of highly skilled, well-paid jobs and supply chain opportunities. We are the only SMR company with multiple commitments to build projects in Europe, testament to our differentiated design and compelling offer.”

International momentum is building. Rolls-Royce SMR has already been selected by leading European utility ČEZ to deliver up to 3 GW of electricity in the Czech Republic. Our success in the UK further strengthens our position in global markets.

ČEZ

In September 2026, Rolls-Royce SMR and ČEZ Group signed an Early Works Contract, marking the next phase in the development of the Czech Republic’s first Small Modular Reactor programme at the Temelín nuclear site in the South Bohemian Region. Building on ČEZ’s strategic investment in Rolls-Royce SMR and Controls the partnership announced in 2024, the agreement enables site-specific design, licensing and permitting activities to begin, supporting the planned deployment of up to 3GW of clean electricity across the Czech Republic.

The contract represents significant progress towards deploying new nuclear power in Europe. By combining the Czech Republic’s strong nuclear heritage with Rolls-Royce SMR’s factory-built approach, the programme will help deliver secure, reliable low-carbon power while creating opportunities for UK and Czech supply chains, supporting industrial growth, skills development and long-term energy security in both countries.

Rolls-Royce SMR and ČEZ have signed a Memorandum of Understanding to enable site preparation activities at two additional sites - Tušimice in the Ústí nad Labem Region and Dětmarovice site in the Moravian-Silesian region (both home to coal-fired power plants).

Videberg Kraft

In June 2026, Videberg Kraft announced the selection of Rolls-Royce SMR as its technology partner to deliver three Small Modular Reactors on the Värö peninsula, on Sweden’s west coast. The agreement will see Rolls-Royce SMR support the deployment of up to 1,500 MWe of clean, reliable electricity, helping to strengthen Sweden’s energy security, support industrial growth and accelerate the country’s long-term net-zero ambitions.

Building on growing momentum across Europe following recent deployment agreements in the United Kingdom and Czech Republic, Videberg Kraft and Rolls-Royce SMR will bring proven nuclear technology, a standardised delivery model and a strong European supply chain to Sweden’s first new nuclear power plant development in more than four decades.
