Hinkley Point C nuclear power station (HPC) is a two-unit, 3,200 MWe EPR nuclear power station under construction in Somerset, England.

​

Hinkley was one of eight possible sites announced by the British government in 2010, and in November 2012 a nuclear site licence was granted.

​

In July 2016, the EDF board approved the project, and in September 2016 the UK government approved the project with some safeguards for the investment. The project is financed by EDF Energy and China General Nuclear Power Group (CGN). The final cost was to be £18 billion in 2015 prices.

​

When construction began in March 2017 completion was expected in 2025. Since then the project has been subject to several delays, including some caused by the COVID-19 pandemic, and Brexit, and this has resulted in significant budget overruns. In EDF's 2022 annual results published on 17 February 2023, the cost was £31–32 billion in 2023 prices, Unit 1 had a start date of June 2027 and a risk of 15 months further delay. In January 2024, EDF announced that it estimated that the final cost would be £31–35 billion (2015 prices, excluding interim interest), £41.6–47.9 billion in 2024 prices, with Unit 1 planned to become operational in 2029 to 2031.
