Dalkia is taking over the reins of the district heating networks of one of France’s five biggest DHC networks • Créteil and Dalkia has signed an agreement for the city’s district heating network – over 80% of the heat should come from renewable and recovered energy • A new €80 million anaerobic digestion plant will supply heat to Lyon's district heating network • Read more about the developments in sustainable heating and cooling in this month's news update from the UK
A significant transition is underway in Chambéry as the Société de Distribution de Chaleur de Chambéry (SCDC) concludes its 36-year tenure in supplying heat to the city. The baton is now passed to Dalkia, entrusted with the role of district heating operator for the next 25 years. The newspaper Le Dauphine states that the primary objective of this handover is to accelerate environmental sustainability efforts of the city and reduce costs for users.
The decision to change management of the network was taken on Monday, December 18, as the city council approved the new public service delegation. The change in management is not without importance in the French market, as the network counts among the five largest heating networks in France. Developed in 1949, the Chambéry heating network spans 58 kilometers and has the capacity to heat approximately 27,500 homes. It has been under the management of the Société de Distribution de Chaleur de Chambéry (SCDC), a subsidiary of Engie Solutions, since 1987. From September 1st, Dalkia will take the reins of the network for the coming 25 years.

On December 8, Mayor Laurent Cathala and Dalkia Ile-de-France Regional Director Benoit Guiblin signed an amendment to the Créteil’s district heating contract, reinforcing the city’s commitment to a sustainable and local energy supply. This amendment ensures that over 80% of renewable and recovered energy will now be utilized in the city’s network, preventing the emission of 71,000 tonnes of CO2. The connection of the city’s northern and southern networks, spanning over 50 km, serves the heating and hot water needs of 40,505 housing equivalents, benefitting nearly 60,000 users, including educational institutions, businesses, and healthcare facilities.
The optimization of the heating network’s efficiency is attributed to its connection to a geothermal well and the Valo’Marne recovery unit, which harnesses heat energy from the incineration of household waste. This environmentally friendly initiative not only safeguards a reduction of CO2 emissions equivalent to nearly 40,000 fewer cars annually, but also the purchasing power of Créteil residents through a reduced VAT rate of 5.5%.

Lyon Métropole has given the green light for the construction of an anaerobic digestion unit at the Pierre-Bénite wastewater treatment plant. The anaerobic digestion plant, a key component of Lyon’s sustainable energy strategy, will transform currently incinerated sludge into a remarkable 77 GWh per year of biomethane. The facility will also generate 11 GWh of waste heat, contributing to the planned district heating network in the southwest area of Lyon.
In total, the project will provide an increased energy supply equivalent to fuelling 300 biogas-powered waste trucks or meeting the heating demands of 13,000 homes, according to an article by Tout Lyon. Notably, the project is poised to prevent the annual discharge of over 20,000 tons of CO2 equivalents.
According to Tout Lyon, the realization of the project will require a investment of €80 million, surpassing the initially planned €48 million budget. The increased investment can partly be explained by the extensive scope of the project, including pipelines to transport sludge from the Saint-Fons wastewater treatment plant for processing.
In addition to the aforementioned sustainability benefits of the anaerobic plant and planned district heating network, the project will also take Lyon another step towards a circular economy by making use the residues from the anaerobic digestion process, known as digestate. This waste is intended to be repurposed as fertilizer for farmers within a 50-kilometer radius of the waste plant.
