The UK will take a 50% stake in the Sizewell C nuclear power project

The British government has announced its support to the development of the 3.2 GW Sizewell C nuclear power project located in Suffolk County (south-eastern England). The government will invest £679m (€786m) in the project and become a 50% shareholder in the project. The investment will allow China General Nuclear (CGN) to exit from the project, in which it holds a 20% stake that the UK government is eyeing after a degradation in China-UK relations. EDF will inject a similar amount to match the government’s stake in the project (50%, down from 80% currently).

In July 2022, the government gave its consent for the planned 3.2 GW Sizewell C nuclear project. A Financial Investment Decision (FID) is expected in 2023; construction should start before 2024 and should last between 9 and 12 years. The £20bn (€23bn) power plant is expected to help the UK become more energy independent and meet its 2050 net-zero emission target.

In 2021, nuclear represented 6.5% of the UK’s total installed capacity with 6.6 GW and 15% of its power generation with 46 TWh. The country plans to get 25% of its electricity from nuclear by 2050.
