EDF / 2020 Universal Registration Document

1 THE GROUP, ITS STRATEGY AND ACTIVITIES Description of the Group’s activities In electricity generation, EDF Energy seeks to secure value from its existing nuclear, coal and gas assets through continued operational excellence and safe, reliable generation. This includes optimising the operations of the West Burton B combined-cycle gas power station and the remaining lifetime value of West Burton A coal power station, which has UK capacity agreements until September 2021, beyond which EDF Energy continues to examine its options, whilst supporting UK Government policy aimed at ceasing coal-fired generation by 2024. EDF Energy is decommissioning the Cottam coal power station that closed in 2019, with a people plan to preserve and develop its capabilities as the business evolves from generation to decommissioning. The same transformation challenge is faced by EDF Energy’s fleet of nuclear advanced gas-cooled reactors (AGRs). Since 2009, EDF Energy has extended the lifetime of its AGR fleet by an average of 8 years. Yet due to non-replaceable major components, there is a technical limit to AGR lifetimes. During 2020, EDF Energy announced the end of power generation at Hunterston and Hinkley Point B AGR stations, from no later than 7 January 2022 and 15 July 2022, respectively. Once the stations stop generating power, the company intends to take on defueling them.

As the AGR fleet approaches its lifetime limit, EDF Energy aims to optimise the end-of-life value and to transform to support new defueling activity (funded by the Nuclear Liabilities Fund – NLF), building on its expertise in operating the UK’s nuclear power stations, whilst continuing to focus on safe and reliable operations of Sizewell B pressurized water reactor and leveraging capabilities and skills to support new nuclear. In partnership with China General Nuclear Corporation (CGN), EDF is building two new nuclear units (3.2GW capacity in total) at Hinkley Point in Somerset, based on the EPR technology. EDF Energy is also working with CGN to progress a similar 3.2GW EPR project at Sizewell in Suffolk, the UK Government having announced in December 2020 that it will enter talks with EDF on the funding of the project (see 1.4.5.1.2.4 “Nuclear New Build business). A further new nuclear power station proposal is being developed at Bradwell-on-Sea in Essex based on CGN’s “UK HPR1000” Chinese technology. As a part of its plans, EDF Energy is also exploring models using nuclear to produce hydrogen and heat.
