PRESENTATION OF EDF GROUP Description of the Group's activities

Composition and specifications of the installed fleet EDF fleet in mainland France With a total installed generation capacity of 89.4GW in mainland France (1) at 31 December 2018, EDF has the largest generation fleet in Europe, accounting for nearly 8.4% of the total installed capacity in the main European countries (the 35 member areas of ENTSO-E – European Network Transmission System Operators for Electricity – that includes Germany, Italy and Spain (2) ). In 2018 in mainland France, EDF’s generation fleet produced 443.3TWh excluding pumped storage hydropower, and 450.6TWh including pumped storage hydropower. At 31 December 2018, the capacity of EDF’s generation fleet was mainly composed of: 58 nuclear units based on pressurised water reactors (PWR) (a unit is defined as ■ a generation unit including a reactor, steam generator, a turbine, a generator,

the related equipment and the buildings that house them). These units have electrical power capacities varying from 900MW to 1,500MW and are spread out over 19 sites, with an average age of 33 years (see section 1.4.1.1 "Nuclear power generation in France"); 20 functioning thermal units, with an average age of around 20 years (see ■ section 1.4.1.4 "Thermal generation in mainland France"); 433 hydropower plants, with an average age of 74 years (3) (see section 1.4.1.5.1 ■ “Hydropower generation in France”); and other hydropower plants owned by Group subsidiaries: SHEMA group ■ (100%) and CERGA (owned 50/50 with the German electricity company EnBW) which represent a total installed capacity of approximately 140MW in 2018.

Other geographic areas and subsidiaries At the end of 2018, the Group also has an installed capacity for electricity generation of 37.1GW (with 133.4TWh of electricity generated in 2018): through EDF Renewables (see section 1.4.1.5.3 "EDF Renewables") with a ■ consolidated installed capacity of 8GW and output of approximately 15TWh; through overseas departments' Island Energy Systems with an installed capacity ■ of 2GW and output of approximately 6TWh in 2018 (see section 1.4.4.3 "Island Energy Systems");

through EDF Energy in the UK with an installed capacity of 14GW and nearly ■ 70TWh generated in 2018 (see section 1.4.5.1 "United Kingdom"); through Edison in Italy with an installed capacity in electricity of 6GW and nearly ■ 20TWh generated in 2018 (see section 1.4.5.2 "Italy"); in the rest of the world with a consolidated installed capacity of 4GW and output ■ of 18TWh (see section 1.4.5.3 "Other international"); through contribution from Dalkia (see section 1.4.6.1.1 "Dalkia"), excluding heat ■ generation, with an installed capacity in electricity of 2GW and output of 4TWh in 2018.
