EDF announces the financial closing of the Sizewell C project. EDF plans to invest a maximum of £1.1 billion during the construction period and will have a stake in the project of 12.5%, alongside the UK government with 44.9%, La Caisse with 20%, Centrica with 15% and Amber Infrastructure with 7.6%, as announced in the final investment decision in July (1). EDF will not invest new cash at financial close due to the reimbursement of the development costs incurred since 2015 and a payment in return for the Hinkley Point C project expertise that Sizewell C benefits from, as well as the series effect.
Sizewell C has secured £5 billion in export credit financing guaranteed by BpifranceAE, as well as debt financing from the National Wealth Fund.
The Sizewell C project involves the construction of two EPR nuclear reactors at the Sizewell site, replicating the Hinkley Point C project led by EDF. It will help provide the United Kingdom with new carbon-free production capacity and generate competitive long-term electricity for six million households.
The EDF group will contribute to the project as a supplier of engineering studies (EDF/Edvance), the main primary circuit including the nuclear boiler, steam generators and safety control system (Framatome) and, for the conventional island, the turbo-alternator unit (Arabelle Solutions).
For the French nuclear industry more broadly with some forty French suppliers, it will help to perpetuate skills, capitalise on experience and generate economies of scale for the EPR2 programme in France.
