Energy solutions tailored to every customer

In a context of volatile energy costs and growing environmental requirements, companies and industrial players must secure their energy supply and meet their climate targets, while keeping costs under control. Around 800 major clients – including L’Oréal, Google, Microsoft and Sanofi – trust ENGIE to address these challenges.

District heating and cooling networks play a key role, as heating and cooling account for around half of final energy consumption in Europe. As the world’s leading district cooling operator and the third-largest district heating operator, ENGIE operates 372 networks in 14 countries. In France, 500 municipalities are served by heating and/or cooling networks, within a broader grid covering 9,500 municipalities through gas networks. In addition, 1,000 renewable energy and storage sites are deployed across the country. Geothermal energy, biomass, solar thermal and heat recovery are adapted to each territory’s resources. In Paris, the Fraîcheur de Paris project illustrates this approach: Europe’s largest district cooling network, supplying iconic buildings such as the Louvre, City Hall, the National Assembly and the Forum des Halles, while reducing their carbon footprint.

ENGIE also helps local authorities reduce energy consumption through gas and electricity network optimisation, photovoltaic deployment and public building renovation. In Marcoussis (Essonne), the largest solar farm in the Île-de-France region supplies electricity to 10,000 people each year. In Vendée, the Terres de Montaigu biomethane unit converts agricultural waste into local renewable energy. This expertise also extends internationally. In Berlin, the Das Neue Gartenfeld district combines cogeneration, solar energy and sustainable mobility, while in Florence, ENGIE improves the energy efficiency of 400 historic buildings – including the Palazzo Vecchio – saving 45,000 tonnes of CO₂ per year.

ENGIE offers electricity contracts sourced 100% from renewable energy (wind, solar and hydropower), as well as gas offers incorporating an increasing share of biomethane. Since 2016, all our electricity contracts in France have been certified by guarantees of origin. For every kilowatt-hour consumed, an equivalent amount produced from renewable sources is injected into the grid.

Beyond energy supply, ENGIE develops digital tools to help households consume energy at the right time – when low-carbon electricity is most abundant – generating savings while contributing to grid balance. In France and Australia, our Ecodéfi+ and Reduce & Reward programmes encourage users to shift their consumption to optimal periods. These solutions also support electric mobility: in Belgium, Empower automatically optimises EV charging, while in France, Elec’Car offers reduced tariffs on green electricity at night.

Our ambition: to make the energy transition reliable, simple and affordable for all. ENGIE was voted Customer Service of the Year 2026 in France for the second consecutive year and ranks among the top-rated energy suppliers in Italy according to consumer association Altroconsumo.
