Dalkia is a leading European energy services company and a wholly-owned subsidiary of EDF Group, headquartered in Saint-André-lez-Lille, France. Founded in 1937 as Chauffage Service, it rebranded as Dalkia in 1998 after evolving through mergers and ownership changes involving Générale des Eaux, Vivendi, and Veolia before full integration into EDF in 2014.
The company specializes in developing local renewable and recovered energy sources—such as biomass, geothermal, and biogas—and delivering energy efficiency solutions to reduce consumption and CO₂ emissions. Its core activities include operating heating and cooling networks, providing energy services for buildings, and supporting industrial sites.
Dalkia serves diverse sectors including residential, healthcare, commercial, local authorities, and industry (e.g., chemicals, manufacturing). Key figures (as of 2023): over 20,000 employees, €6.4 billion revenue, 330 networks (3,000+ km), 90,000 energy facilities managed, 3,800 industrial sites, and 4.3 Mt CO₂ avoided.
