Wylfa in Anglesey is the Government's choice for the UK's third mega-nuclear power station, positioning North Wales in prime position to gain economically and support the country's long-term energy security.

The government is initiating discussions with international energy companies to consider constructing the new power plant. This facility could supply clean and dependable energy to approximately six million households for 60 years. This move advances the UK's goal of sourcing up to a quarter of its future electricity demand from domestic nuclear power by 2050, enhancing the nation's energy autonomy.

The government is exploring building a major nuclear power station, similar in scale to Hinkley in Somerset and Sizewell in Suffolk. This new project would revive the nuclear history of Wylfa and bring thousands of jobs and investment to the area, boosting the local economy.

Wylfa, situated on the North Wales coast, is ideally positioned to host a nuclear plant due to its close proximity to cooling water and its nuclear heritage.

Great British Nuclear - tasked with delivering the world’s fastest small modular reactor competition - recently secured Wylfa and Oldbury-on-Severn in Gloucestershire as 2 possible sites for new nuclear projects. It was the first time the government acquired land for new nuclear since the 1960s.

Secretary of State for Energy Security and Net Zero Claire Coutinho, said: "We are powering ahead with the biggest expansion of nuclear energy in 70 years. Anglesey has a proud nuclear history and it is only right that, once again, it can play a central role in boosting the UK’s energy security. Wylfa would not only bring clean, reliable power to millions of homes – it could create thousands of well-paid jobs and bring investment to the local area."


The UK is delivering the biggest expansion to nuclear power in 70 years, aiming to quadruple its nuclear capacity to up to 24GW by 2050. Identifying suitable sites is paramount to achieving this ambitious goal. The expansion will involve a combination of traditional large-scale power plants and small modular reactors, offering the advantage of quicker deployment and scalability.

Meanwhile Great British Nuclear aims to announce successful bidders for the small modular reactor competition by the end of this year.

Gwen Parry-Jones CEO of Great British Nuclear added: "Having agreed to purchase the Wylfa site earlier this year, GBN looks forward to working with the government on the market engagement programme for large scale gigawatt providers and also delivering this vital project in the years to come."

Secretary of State for Wales David TC Davies stated: "This is significant and welcome news for Wales that promises to bring thousands of high-quality jobs to the local economy. Alongside the revival of nuclear power at Wylfa, recent measures we have announced include a Freeport for Anglesey, £17 million in Levelling Up money for Holyhead and electrification of the North Wales rail line which show that the UK government continues to deliver for Anglesey and for North Wales."

Sue Ferns Senior Deputy General Secretary of Prospect union commented: "Wylfa represents the best site in Europe for a large-scale nuclear power station. With this announcement this has now been recognised by the UK government.

"Gigawatt scale new nuclear power stations are vital to hitting net zero and for our energy security. But they also maintain well paid and highly skilled jobs, meaning this project would be a major boost to the Welsh economy. Now we need a laser-like focus on delivery of new nuclear to make sure skills and experience are not lost, and costs are reduced as we progress."

Tom Greatrex Chief Executive of the NIA said: "The government is absolutely right to pursue more large-scale nuclear alongside the SMR programme: it is proven technology that delivers clean, sovereign power and can transform communities with thousands of high quality, long term jobs and apprenticeships. Wylfa is an ideal place for a big nuclear project, and the community knows nuclear.

"We welcome the government’s engagement with potential partners internationally, and we urge them to move forward at pace. A large-scale project at Wylfa would be the single biggest inward investment in Welsh history, and a huge step towards both energy security and net zero for the whole country."
