The Hinkley Point C project successfully delivered J-0, the completion of the nuclear island “common raft” for its first unit in June 2019, in line with the schedule announced in September 2016.

Following this major milestone a detailed review of the project’s costs, schedule and organisation was performed.

The review has concluded that:

  • The next milestone of completing the common raft for Unit 2 in June 2020, which was announced earlier this year, is confirmed ;
  • The previously communicated risk of COD delay of unit one and two (of 15 months and nine months respectively) has increased(1)
  • The project completion cost(2) is now estimated between £21.5bn and £22.5bn, an increase of £1.9bn to £2.9bn(3) compared to the previous estimate.

The range depends on the effectiveness of action plans to be delivered in partnership with contractors.

Cost increases reflect challenging ground conditions which made earthworks more expensive than anticipated, revised action plan targets and extra costs needed to implement the completed functional design, which has been adapted for a first-of-a-kind application in the UK context.

Under the terms of the Contract for Difference, there is no impact for UK consumers or taxpayers.

EDF’s project rate of return for Hinkley Point C (IRR)(4) is now estimated between 7.6% and 7.8%.

The management of the project remains mobilised to begin generating power from Unit 1 at the end of 2025. To achieve this, operational action plans overseen by the project management are being put in place. These involve the EDF Group's engineering teams in Great Britain and France, buildings and ancillary works contractors, and suppliers of equipment and systems throughout the supply chain.

(1) As previously communicated in July 2017, if this risk were to materialise, it would entail an additional cost of around £0.7bn in 2015 sterling. Under this assumption the IRR for EDF would be lower by 0.3%.
(2) In 2015 sterling, excluding interim interest and excluding forex effect versus the reference exchange rate for the project of 1 sterling = 1.23 euro.
(3) Additional costs net of action plans
(4) EDF equity IRR calculated at the exchange rate 1 sterling = 1.15 euro and including the capped compensation mechanism in place between shareholders.

About EDF

EDF is helping Britain achieve Net Zero by leading the transition to a cleaner, low emission electric future and tackling climate change. We're Britain’s biggest generator of zero-carbon electricity(1), meeting around one-fifth of the country’s demand and supplying millions of customers with electricity and gas.

With around 5 million accounts, EDF is one of the largest suppliers to British homes and businesses and a leading supplier of innovative energy solutions that are helping businesses become more energy independent. All of our home and small business customers get energy tariffs backed by zero-carbon electricity as standard.

We generate low carbon electricity from eight nuclear power stations, more than thirty onshore wind farms and two offshore wind farms, and operate one of Britain’s biggest battery storage units, one gas and one coal power station, thousands of EV charge-points, and combined heat and power plants. Wind, nuclear and solar all produce electricity that is zero carbon at the point of generation and have similar emissions over the build, run and retire lifecycles.

EDF is leading the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C, and is leading the development of plans for a replica at Sizewell C in Suffolk. Hinkley Point C and Sizewell C will provide low carbon electricity to meet 14% of UK demand and power around 12 million homes. 

EDF is one of the UK’s largest investors in renewables, with 1GW of renewable generation in operation and over 4GW in construction, planning and development across a range of technologies including onshore and offshore wind, solar and battery storage. We are constructing our largest offshore wind farm in Britain – the 450 MW Neart na Gaoithe project in Scotland which will be ready in 2023.

Our energy services business, Imtech, is one of the largest technical service providers in the UK and Ireland.

EDF is part of EDF Group, the world’s biggest electricity generator. In the UK we employ around 13,000 people.
