PRESENTATION OF EDF GROUP Description of the Group's activities

implement energy efficiency actions and promote the insertion of renewable ■ energies onto the network; ensure the monitoring of the load sharing perimeters; ■ be the guarantor for the distribution and accounting for the energy flows ■ between the network user players, and the fair compensation of losses on these networks; provide services for the LDCs, distributors and organising authorities mentioned ■ respectively in sections III and IV of Article L. 2224-31 of the French Local Authorities Code. Distribution activities 1.4.4.2.2 Enedis’ business is based on a number of activities: manage, in its capacity as the concession holder, the assets under concession; run and maintain the network in such a way as to ensure the continuity of supply; carry out work on the network (in particular, network connection, reinforcement and renewal work); provide access to the network to all users in the framework of contractual provisions in force; and manage the meter fleet, as well as obtaining, processing and transmitting data on network user consumption. Change in investments In 2017, Enedis invested €3,767 billion, of which €1,411 billion were mainly devoted to connections for new customers and producers, as well as to the reinforcement of the network. In addition, the contracting authorities invested €721 million in 2017. In all, almost €4.5 billion were invested on the distribution networks in 2017 in mainland France.

These missions are: define and implement operational, investment and development policies in ■ relation to the electricity distribution network; provide connection and access for users to these networks under objective, ■ transparent and non-discriminatory conditions, as well as inter-connection with other networks; provide users with the information needed to access the network efficiently ■ (information protected by regulations or law excepted); oversee relations with the energy regulation authorities (Ministry of Energy, the ■ Energy Regulation Commission (CRE), public distribution contracting authorities) in line with its activities; oversee relations with local authorities; ■ negotiate, conclude and manage concession contracts; ■ operate, service and repair the electricity distribution networks; ■ design and build infrastructure, as well as manage work on the networks; ■ carry out metering activities for users connected to the networks, particularly as ■ regards supply, installation, meter inspection, maintenance and renewal of metering devices, as well as managing data activities and any other missions relating to its work as a whole;

battered a large portion of France, from Brittany to the Côte d'Azur; and in December, when Storm Anna struck the regions of Pays de la Loire, Brittany and Hauts de France. Enedis support teams were also sent to Ireland as well as to the French West Indies (Guadeloupe, Saint-Martin and Saint Barthélemy) when Hurricanes Irma and Maria struck. As regards insurance cover for the protection of the overhead distribution network against the effects of large scale storms, see section 2.5.5.3 “Storm cover”. Development of renewable energies Over the Enedis perimeter, the number of solar panel generation installations connected to the network grew again: in 2017, an upswing in photovoltaic connections was observed with 755MW of new photovoltaic facilities connected (compared to 540MW at the end of 2016), the increase in wind power generation connected to the public distribution network has also continued, with 1,300MW connected in 2017 (compared to 1,200MW in 2016). At the end of 2017, a total of around 18.2GW in photovoltaic and wind power generation was connected to the Enedis grid,made up of 6.5GW from photovoltaic plants and 11.7GW from wind power generation. To the power thus generated are added other sources of power generation, in particular “historical” hydropower plants (1.5GW), cogeneration (2.2GW), biogas, biomass and dispatchable fossil-fuel thermal. In all, at the end of 2017, the generation fleet connected to Enedis was around 23.7GW.

The additional resources thereby committed are dedicated to the quality of the service, to securing the networks, to the security and preservation of the environment, areas where the identified expectations of customers, local authorities and concession authorities are particularly strong. This level of investment allows Enedis to carry out asset renewal programmes. To complement these investments, Enedis continues its efforts in the preventative maintenance of networks, in particular for work relating to tree topping. This came to €327 million in 2017 (compared to €332 million in 2016). Quality of service Quality of service is one of Enedis’ main objectives. In 2017, the average outage time excluding transmission incidents and excluding exceptional incidents was 65 minutes which is a good result for a year marked by climate variations. The quality of service provided is also reflected by maintaining steady voltage levels, kept as close as possible to the level set by regulations, and by minimising the number of outages. To respond to large-scale incidents, Enedis relies on an Electricity Rapid Intervention Force (FIRE), which allows it to mobilise, at any time, in an affected region, the teams and resources from other regions in order to restore customers’ electricity as rapidly as possible. In 2017, FIRE was deployed on four occasions: in January, when Cyclone Egon lashed both Normandy and Picardy; in early February, when three successive windstorms, named Kurt, Leiv and Marcel, impacted the Nouvelle-Aquitaine region in southwestern France; in early March, when Storm Zeus
