As part of its sustainable development policy, the city of Aurillac wanted to promote the wood energy sector in the region: a renewable energy sector, local and not relocatable, to offer its inhabitants a low carbon impact energy and at moderate cost in time.
The completion of a feasibility study confirmed the interest of a wood heating network for the city.
Thus, the municipality offers future subscribers of the heating network, an alternative energy to conventional heating modes by achieving multiple objectives:
- energize and support the local economy,
- to ensure energy production, most of which comes from renewable sources,
- to provide users with heat at a price lower than their reference energy.
ENGIE Cofely was selected for the financing and design of this wood heating network and a 24-year operating phase, starting with the commissioning of the facilities, scheduled for the last quarter 2019.
The boiler will include two biomass boilers and two gas boilers (complement or backup) for a total thermal power of 27.5 MW PCI.
COMPTE.R was chosen as a supplier of two 6.5 MW PCI and 3 MW PCI biomass generators that will equip the future boiler room.
This boiler room will be built near the sorting center, Yser. There, wood by-products will be used to feed both boilers.
The 15 km long district heating network, with its centralized heat production, is an ecological system that combines economy, safety, comfort and environmental performance.
