PRESENTATION OF EDF GROUP Description of the Group's activities

Renewable energy generation 1.4.4.4.4 Deep geothermal energy

In 2017, ÉS also launched the Illkirch Graffenstaden geothermal project, designed to supply power to the future heating network which will supply the innovation park and surrounding areas. This project is being carried out by the wholly-owned subsidiary, ÉS Illkirch Géothermie. The investment amounts to €37 million. This power plant with a thermal input of 26MW is a cogeneration plant (thermal and electricity generation). Biomass In the area of biomass, the ÉS group commissioned at the end of 2016, through its majority ownership in the ÉS Biomasse company, a biomass cogeneration plant. This power plant produces 70GWh of electricity from renewable sources and 112GWh of heat from renewable sources per year, which feed two of the three principal heat networks for the city of Strasbourg.

The ÉS group is one of the leading players in deep geothermal energy in France. It holds a 40% equity stake in the ECOGI (Exploitation of geothermal heat for industry) project, which built, in partnership with the Roquette company and the Caisse des Dépôts, the first deep geothermal energy power plant for industrial use at Rittershoffen, with the support of the ADEME, the Grand-Est Region and SAF-Environnement. This power plant has been producing 24MW of thermal renewable superheated water using a geothermal resource located at a depth of more than 2,500 metres since September 2016. In addition to the projects under review, the ÉS Group has also transformed, with its partner EnBW, the deep geothermal energy research site at Soultz-sous-Forêts into an industrial installation for the production of electricity. This geothermal power plant has been producing 1.7MW of electricity since July 2016. United Kingdom 1.4.5.1 EDF group activity in the United Kingdom (UK) is led by EDF Energy focusing on energy supply and electricity generation. The Group is also active in oil and gas exploration and production in the North Sea viah EDF Production UK, a subsidiary of Edison (see sections 1.4.5.2.3.2 “Hydrocarbon business” and 1.4.6.2.2.3 “Exploration and Production (E&P)"). EDF Energy is principally active in the generation of electricity in the UK, the supply of electricity to domestic and business customers, the supply of gas to domestic customers and in the construction of new nuclear generation and renewable generation. Total electricity generated in the UK in 2017 was c.335TWh and total electricity supplied was c.296TWh (the difference principally reflecting losses on the transmission and distribution networks). Total gas supplied to UK domestic customers in 2017 was 295TWh. EDF Energy is one of the UK’s largest energy companies and the largest producer of low-carbon electricity, producing around INTERNATIONAL ACTIVITIES 1.4.5

1.

one-fifth of the nation’s electricity from its nuclear power stations, wind farms, coal and gas power stations and combined heat and power plants. The company supplies gas and electricity to 5.5 million business and residential customer accounts and is the biggest supplier of electricity by volume in Great Britain. EDF Energy is leading the UK’s nuclear renaissance. In partnership with China General Nuclear Corporation (CGN) it begun construction of the Hinkley Point C power station in Somerset and is developing further new nuclear projects at Sizewell, in Suffolk, and Bradwell, in Essex. It employs over 12,500 people at sites throughout the country. The workforce is highly engaged with 82% taking part in the annual employee survey with an engagement index score of 75%. 78% would recommend EDF Energy as a good place to work and 79% are proud to tell people where they work. 91% of employees go the ‘extra mile’ to ensure the success of EDF Energy.
