Launch date and phases of commissioning of the heating network
The official launch of the heating network in the south of Rennes took place in early 2023. The project has been broken down into several phases to ensure a gradual and efficient commissioning. Each phase has been carefully planned to minimize service interruptions and maximize energy efficiency.
The first phase covered the neighborhoods of La Poterie and Le Blosne, allowing for initial distribution to approximately 9,500 dwellings. The second phase extended the network to Bréquigny and Clémenceau, integrating an additional population of 10,000 households. The final phase, scheduled for the end of 2024, will include Le Colombier, thus reaching a total coverage of 16,000 dwellings.
Phase 1: Initial installation and testing of biomass
Phase 2: Extension to geothermal and solar thermal
Phase 3: Finalization with heat recovery and complete integration
Phase | Year | Included Neighborhoods | Dwellings Covered |
|---|---|---|---|
1 | 2023 | La Poterie, Le Blosne | 9,500 |
2 | 2023-2024 | Bréquigny, Clémenceau | 10,000 |
3 | End of 2024 | Le Colombier | 16,000 |
