PRESENTATION OF EDF GROUP Description of the Group's activities

21 functioning thermal units, with an average age of around 16 years; ■ 433 hydropower plants, with an average age of 73 years (1) (see section 1.4.1.5.1 ■ “Hydropower generation in France”); the wind and solar power generation capacities of EDF Énergies Nouvelles in ■ France (see section 1.4.1.5.3 “EDF Énergies Nouvelles”) and the incineration plants of the Tiru group in France (see section 1.4.6.1.1 “Dalkia” – “Tiru”); 84 hydropower plants owned by Group subsidiaries: SHEMA group (100%) and ■ CERGA (owned 50/50 with the German electricity company EnBW). These plants represent a total of approximately 140MW of installed capacity in 2017.

In 2017 in France, EDF’s generation fleet produced 425.2TWh excluding pumped storage hydropower, and 432.0TWh including pumped storage hydropower. At 31 December 2017, the capacity of EDF’s generation fleet in mainland France was 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 32 years;
