PRESENTATION OF EDF GROUP Description of the Group's activities

modification of the energy mix for greater efficiency and less CO 2 ■ optimisation of cogeneration and the development of renewable energies (biomass, geothermal, energy recovery of waste, biogas, etc.); additional services in order to better enhance assets (for example, support service ■ for the electricity grid). Thus, Dalkia is one of the leaders in France in the management of urban heating and air-conditioning networks, operating 350 heating or cooling networks, both urban and local, and providing heat to 2.3 million homes. Deploying this model across its geographic targets will constitute a significant part of its future growth. Industrial utilities Dalkia is active in the industrial utilities business for 2,030 industrial sites. The challenges are to improve environmental performance (particularly by controlling CO 2 emissions and the valuation of energy recovery), competitiveness and security of supply. Dalkia’s strategy is to allow its industrial customers to concentrate on their core processes, by assuming responsibility for the generation of their utilities and the technical management of their facilities, while optimising their energy use and their greenhouse gas emissions. Dalkia differentiates itself by a large and coherent range of services, which includes the optimisation of industrial utilities (steam, electricity, cold, compressed air); adjustment of usage to requirements, and identification of sources of unavoidable energy and recoverable co-products, optimisation of industrial building usage, and reduction of greenhouse gas emissions. Building energy services Building energy services consist of management of the energy facilities in buildings: optimisation of local thermal energy generation, transformed energy supply, operation and maintenance of technical facilities. They also seek to improve the operation of existing systems in order to maximise their effectiveness and to reduce their CO 2 emissions. Dalkia provides integrated energy services ranging from the design, construction and upgrading of facilities, to transformed energy supply and management and maintenance of facilities, for tertiary, industrial, public-sector and private-sector customers. Key achievements for Dalkia in 2017 With respect to heating networks, Dalkia completed extensions and the creation of new urban heating networks that use renewable and recovery energies (like those in Lyon, Charleville-Mézières, Sarreguemines, Béthune, Poitiers, Limoges, etc.). In this regard, renewable and recovery energies currently represent 37% of Dalkia's energy mix. For building energy services, emphasis is placed on energy performance contracts which include the thermal renovation of the buildings. In addition, Dalkia continues to find economic and environmental performance solutions for industrial customers, through for example cogeneration development (Toyota, Munksjo, PSA, etc.). Dalkia has also continued its development and actions internationally by acquiring Imtech in the UK, through the joint venture EDF Energy Services jointly held with EDF Energy, and by acquiring 100% of the share capital of Matex Controls in Poland. Main subsidiaries of Dalkia in France Optimal Solutions Optimal Solutions, a wholly-owned subsidiary of the Dalkia group, positions itself as a specialist in the design and realisation of energy efficiency solutions in France, strongly complementing Dalkia's regions, through two activities: energy performance of buildings for local authorities and the tertiary and residential sector, and energy performance of electrical facilities and equipment for the services and industrial sector. Tiru The Tiru company, a subsidiary 75% owned by the Dalkia group, is specialised in waste recovery serving local authorities and industrial customers: , with the

waste recovery via incineration, methanisation and boilers running on solid ■ recovered fuel (SFR) able to generate electricity, steam or biogas; materials recovery via compost, the sorting and packaging of recyclable materials ■ and solid recovered fuel generation. Tiru designs, builds and currently operates facilities located in France, Great Britain Cesbron, a wholly-owned subsidiary of the Dalkia group, is specialised in the design, installation and maintenance of cooling solutions for industrial and tertiary customers. It also provides cooling solutions, air treatment, reversible heating and processes for bakeries and industrial kitchens. Dalkia Biogas The Dalkia Biogas group (formerly Verdesis), a wholly-owned subsidiary of the Dalkia group, is specialised in the generation and recovery of biogas. It is present in France and Belgium and provides the following services: industrial, agricultural or territorial methanisation, biogas processing (drying and filtration), biogas recovery by cogeneration or treatment and biomethane injection. The CRAM group is a regional player mainly specialised in building energy services. In 2017, Dalkia increased its stake in the capital of CRAM SAS from 85% to 95%. Techsim The Techsim company, a wholly-owned subsidiary of the Dalkia group, is specialised in energy solutions for the generation of compressed air, nitrogen and breathable air in the industrial and nuclear sectors. and Canada. Cesbron The Matex Controls company, based in Poland, designs, builds and maintains technical facilities (ventilation, heating, air conditioning, fire protection, etc.) for commercial buildings and industrial customers. It also provides innovative solutions for the building's energy performance management, including VEMS© (Virtuel Energy Management System). The ZEC company is mainly specialised in the generation and distribution of heat in the region of Katowice in Poland (Upper Silesia). It has recognised expertise in the energy recovery of mine gas to be used by heating networks and electricity distribution facilities. Fenice Rus Specialised in energy efficiency for industrial customers, Fenice Rus is one of the pioneers in the energy services sector in Russia. Imtech Imtech, a company acquired by Dalkia in 2017, is specialised in thermal and electrical engineering, technical maintenance of facilities and the integration of acquisition and data control systems in the United Kingdom and Ireland. Imtech provides its services to the construction, industry, services sector and local authorities. Groom Energy Solutions Groom Energy Solutions LLC provides companies and industrial customers with a comprehensive approach to consultancy, project management and the performance of energy efficiency work, with nationwide coverage in the United States. Citelum 1.4.6.1.2 Citelum is the subsidiary of the EDF group dedicated to smart lighting and connected services, and one of the leading players in the field in France and throughout the world. The Asteriot company provides solutions dedicated to fluids management and energy optimisation in collective-use buildings (housing units, tertiary, administrative buildings) by using information collected from connected objects. The Dalkia group acquired a 51% stake in Asteriot in June 2017. Main subsidiaries of Dalkia abroad Matex Controls
