Sizewell C nuclear power station
Sizewell C nuclear power station is a project to construct a 3,200 MWe nuclear power station with two EPR reactors in Suffolk, England. The project was proposed by a consortium of EDF Energy and China General Nuclear Power Group, which own 80% and 20% of the project respectively. In 2022, UK Government announced a buy-out to allow for the exit of CGN from the project and forming a 50% stake with EDF, though EDF expect this to fall below 20% following anticipated external investment. The power station is expected to meet up to 7% of the UK's demand if it comes into service.
