Rolls-Royce SMR named finalist by Vattenfall to deliver nuclear power technology for Sweden’s future energy needs

(IN BRIEF) Rolls-Royce SMR has been selected by Vattenfall as one of only two finalists in Sweden’s nuclear technology procurement process. Following its shortlisting in 2024, Rolls-Royce SMR successfully completed detailed evaluation and will now work with Vattenfall on the final stage of selection, which could result in the delivery of three SMRs for the Ringhals site on Sweden’s Värö Peninsula. Each unit would generate 470 MWe of clean electricity for more than 60 years, enough to power one million homes. The announcement builds on recent wins for Rolls-Royce SMR in the UK and Czech Republic and reflects growing international recognition of its modular approach to nuclear power as Sweden targets an additional 100–250 TWh of electricity over the next 25 years.

(PRESS RELEASE) LONDON, 22-Aug-2025 — /EuropaWire/ — Rolls-Royce SMR has been named by Vattenfall as one of just two companies advancing to the final stage of its nuclear technology selection process, marking a major step toward the deployment of small modular reactors (SMRs) in Sweden.

After being shortlisted in 2024, Rolls-Royce SMR has now progressed through a detailed evaluation and will work closely with Vattenfall to complete the final assessment phase. The outcome could see Rolls-Royce SMR deliver an initial three units, contributing to Sweden’s future electricity supply and energy security.

Chris Cholerton, Chief Executive of Rolls-Royce SMR, said:
“We are extremely proud to be one of the final two nuclear technologies selected by Vattenfall in this highly competitive process. This decision underlines confidence in our proven SMR design and our modular approach to delivering nuclear power. Today’s announcement builds on recent momentum following our selection by Great British Energy – Nuclear to deploy the UK’s first SMRs, and by CEZ in the Czech Republic to deliver up to 3GW of clean electricity. We look forward to deepening our collaboration with Vattenfall and further strengthening the UK-Sweden partnership in advancing clean energy solutions.”

Sweden’s long-term energy demand is projected to rise by 100–250 terawatt-hours over the next 25 years. Nuclear power is expected to play a pivotal role in achieving this, with Vattenfall focusing on deploying the first new units at the Ringhals site on the Värö Peninsula, which already hosts a nuclear power station.

Each Rolls-Royce SMR unit is factory-built to streamline deployment and reduce construction risk. With an output of 470 MWe, a single unit can supply electricity to one million homes and operate for over six decades, providing a stable source of low-carbon power that complements renewable generation and supports national net zero goals.
