Heating and cooling: efficient, green, smart networks!
Harnessing clean, local, inexpensive energy to provide district heating, domestic hot water and air conditioning. We are a major player in heating and cooling networks which builds and operates urban networks covering districts, cities and metropolitan areas. Today in France, some 2.3 million people already rely on a heating network. You could be the next to benefit from our expertise!
The concept: heating with a collective network
Heating networks supply heating - and often domestic hot water - to an entire district or city. These production facilities can be supplied by renewable energy (biomass, geothermal, marine, etc.) and recovered energy (from household waste, heat from data centres or industry, etc.). It is a method that is becoming more widespread. France’s energy transition law aims to achieve a fivefold increase in the amount of renewable and recovered energy delivered through these networks by 2030.
But that is just the tip of the iceberg! Dalkia combines modern technologies and creates synergy between different forms of energy and uses to develop more intelligent, connected networks called ‘smart grids’. It is now possible to predict spikes in demand and even store renewable energy. We continually improve the networks to better recover energy.
We also produce cooling in our networks, providing localized, dedicated air conditioning for groups of buildings which is eco-friendly and efficient, either jointly with heating or in separate cooling networks.
Heating and cooling networks are driving forward the energy transition process at regional level, serving all types of buildings, from residential complexes to schools, hospitals, offices, industrial sites and more.
We’re here to help you design, build and operate your own heating or cooling networks.
Dalkia operates over 330 heating and cooling networks with 2,900 km of pipes.

Did you know? Heating is the top energy expense in France, accounting for nearly 50% of energy consumption.
France has 780 heating networks and just 23 cooling networks.
The potential is huge! The energy transition law introduced in France in 2015 aims to achieve a fivefold increase in the amount of renewable and recovered energy delivered through these networks by 2030.
The country’s multi-year energy programme aims to connect the equivalent of 3.4 million homes to a heating network by 2023.
Heating networks used to rely mainly on fossil fuels (oil, natural gas, coal, etc.), which emit large amounts of CO2. Nowadays, the focus is on renewable and recovered energy: biomass, geothermal, marine, solar, household waste, and waste heat recovered from data centres and industrial processes such as iron and steel making. In 2018, heating networks avoided some 6.13 million tonnes of CO2 emissions, the equivalent of taking 2.9 million cars off the road.
Green energy now accounts for over 50% of the energy mix in heating networks.
Furthermore, heating networks are synonymous with the creation of new jobs! Renewable and recovered energy often comes from local sources such as geothermal and marine energy sites and waste-to-energy facilities. And many local companies are involved in building each network.
