EDF has announced that the Hinkley Point C nuclear power project currently being developed in Somerset (United Kingdom) will require an additional investment of £500m (€565m), with a total cost reaching £22-23bn (€25-26bn). In addition, the first unit is now expected to produce first power in June 2026, compared to end-2025 as initially announced in 2016.
The Hinkley Point C project is developed by EDF, CGNPC and CNNC and will consist of two 1,630 MW Areva EPR reactors (namely Hinkley Point C-1 and Hinkley Point C-2). In September 2019, EDF announced that the project will require an additional investment of £1.9bn (€2.2bn) to £2.9bn (€3.3bn) for completion, due to challenging ground conditions making earthworks more expensive than anticipated, revised action plan targets and extra costs to implement the completed functional design. According to EDF, the risk of COD delay of units 1 and 2 is maintained at respectively 15 months (commissioning in 2027 instead of late 2025) and 9 months (commissioning in 2027).
