The second-largest solar district heating plant in France supplies renewable heat to the city of Narbonne’s heating network. The district heating network serves various structures, including social housing and buildings in Narbonne city.

The core principle of this solar thermal integration involves heating the network through end-of-network integration, resulting in significant fossil fuel savings, particularly in gas consumption.

 

Additionally, the system optimizes the biomass boiler functionality in winter through the pooling of the storage tank.

The project developer, Newheat, owns the plant and sells the thermal energy to the City of Narbonne through a Heat Purchase Agreement signed for a duration of 25 years.
