Lyon Metropolis and Dalkia Connect Renault Trucks Site to Urban Heating Network
Lyon, February 3, 2026 – The Lyon Metropolis and Dalkia have reached a new milestone in the development of the Centre Métropole heating network with the connection of the Renault Trucks industrial site in Saint-Priest. This connection, operational since early February 2026, signifies a major advancement in shared energy infrastructure for industrial transition.
Expanding the Heating Network Towards Eastern Lyon
Managed by the Lyon Metropolis and operated by its delegate Dalkia, through the ELM company, the Centre Métropole heating network continues its expansion into Eastern Lyon. The branch connecting the Puisoz substation to the Saint-Priest area is now fully operational.
This extensive project involved the creation of 16 kilometers of new pipelines, known as feeders, designed to transport heat to the industrial zones concerned. The total investment for this expansion amounts to 36 million euros, with support from Ademe.
An Infrastructure Supported by a Renewable Energy Mix
The network primarily utilizes heat generated from waste recovery and progressively integrates new local renewable energy sources. This energy mix aims to achieve a 74% share of renewable and recovery energies by 2027.
According to the data provided, this installation is projected to prevent the emission of nearly 50,000 tons of CO2 annually, which is equivalent to removing 25,000 vehicles from circulation.
Targeted Investment for the Renault Trucks Site
The connection of the Renault Trucks industrial site in Saint-Priest includes the establishment of a 6 MW substation and associated branching works. This specific project represents an investment of 2.1 million euros.
This amount is borne by the delegate ELM as part of the overall 500 million euro program outlined in the public service delegation. Renault Trucks contributes 629,000 euros to the financing, corresponding to the connection fee.
Energy Security for Industrial Activity
Now powered by the metropolitan heating network, the Saint-Priest site centralizes its heating system and replaces fossil fuels with decarbonized heat.
In addition, Renault Trucks has implemented an internal industrial heat recovery system. The public network secures and complements this installation, providing a comprehensive, high-performance environmental solution.
A Tool for Competitiveness and Transition
This extension is designed to cover thermal power equivalent to the needs of 3,700 homes, in addition to the connected industrial sites. It enables the replacement of gas and fuel oil with local renewable and recovery energies.
Beyond the climate challenge, the network serves as a shared public infrastructure aimed at securing the energy supply for economic actors in the region.
For the Lyon Metropolis and Dalkia, this project confirms the strategic role of heating networks in energy sovereignty and the reduction of industrial carbon footprint, while supporting businesses in achieving their performance and competitiveness goals.
