Sizewell Power Plant

Sizewell B

Sizewell B is the UK's only commercial pressurised water reactor (PWR) power station. Its single reactor was built and commissioned between 1987 and 1995, and first synchronised with the national grid on 14 February 1995. The main civil engineering contractor was John Laing. The power station is operated by EDF Energy. The architectural design was carried out by Yorke Rosenberg Mardall.

EDF's strategic target is for a 20-year life extension for Sizewell B PWR, beyond the current accounting closure date of 2035. This would mean the plant remaining in operation until 2055. EDF reaffirmed this plan in December 2024. As of 2022, the power station is still planned to close in 2035. However, a government official is cited stating that "it probably will be extended", while EDF intends to take a final decision on the estimated investment of £500-£700 million in 2024.

• Station Director: Robert Gunn
• Reactor type: 1 Pressurised Water Reactor
• Total supply to the national grid: 1198 MW
• Start of construction: 1988
• Start of generation: 1995
• Estimated decommissioning date: 2035
• People: Approximately 520 full time EDF employees plus over 250 full time contract partners

Sizewell C

Sizewell C will provide decades of clean, reliable electricity for around 6 million homes. Together with wind and solar, it will help to build a greener energy system and protect households from high gas prices.

Majority owned by the UK Government, Sizewell C is a British nuclear project which will strengthen our energy security while providing thousands of great jobs across the country.

Their project is already helping to spread prosperity and change lives for the better in East Suffolk. They are creating huge new opportunities for local people and businesses. At the same time, they are listening carefully to residents and working hard to reduce the disruption caused by the construction of the power station.

The project will support 70,000 jobs, including 7,900 in Suffolk, and they will employ at least 1,500 apprentices.

Sizewell C will help to change lives for families and communities across the UK, including in places that are crying out for skilled work. They have active policies to promote a diverse workforce and to spread opportunities as widely as possible.

The biggest threat to nature is climate change. Clean energy from nuclear will reduce carbon emissions and help to protect the environment. At Sizewell C, they are creating stunning new habitats for nature.

They are also going well beyond legal requirements to mitigate the impacts of construction. Their plans will result in more local biodiversity, more nature recovery and more rewilding in the East of England.
