What Coriance does

Coriance is a French district heating and cooling operator that designs, builds, and operates urban thermal energy networks under long-term public service delegation (DSP) contracts with municipalities and local authorities. Headquartered in Noisy-le-Grand and operating since approximately 2000, the company runs 47 heating and cooling networks totaling 583 km across 45 cities in France and Belgium (Wallonia), serving residential, public, healthcare, and industrial end-customers. Customer-facing subsidiaries (CenergY, GéoBrie, ERIVA, Énergie Verte de Meaux, Eneriance, and others) are typically structured as dedicated concession vehicles, each tied to a specific territory's DSP.

The company's technology stack is built around four complementary renewable and recovery energy sources: deep geothermal drilling (notably the Dogger aquifer at ~1,700 m depth, with 31 wells across 10 networks supplying 15% of the portfolio), biomass combustion (27% of the mix, including 2x12.5 MW Dall Energy two-stage gasification boilers claimed at up to 110% efficiency at the Chemin Vert Caen facility), energy recovery from waste-to-energy and industrial processes (25% of mix), and cogeneration (11%, with 168 MW installed electrical capacity). The company reports a 73% renewable and recovery energy share across its portfolio — claimed as the greenest in its segment — and 550,000 tonnes of CO₂ avoided annually.

Coriance monetizes through three revenue streams: (i) construction and development of new networks under long-term concession contracts, (ii) ongoing operation and maintenance fees (managed-services/recurring), and (iii) usage-based sales of thermal energy to connected subscribers. Pricing is set within DSP frameworks rather than published commercially, and the company pursues new business via competitive tenders issued by collectivités, supported by an eligibility-testing funnel on its corporate website and six regional agencies covering Île-de-France, Grand-Ouest, Grand-Est, Sud-Est, Sud-Ouest, and Belgium. ISO 9001/14001/50001/45001 certifications back the operational quality system.

Revenue model

1. Construction and Development of District Heating Networks: Coriance designs, constructs, and develops new district heating and cooling networks under long-term public service delegation contracts with municipalities and local authorities. Revenue is generated through capital investment in infrastructure and development fees.
2. Operation and Maintenance of District Energy Networks: Ongoing exploitation of district heating and cooling networks, including heat production, distribution, and network management. Revenue derived from service fees under long-term concession contracts.
3. Heat and Energy Distribution Sales: Sale of thermal energy (heating and cooling) to connected residential, commercial, public, and industrial customers through the district heating network. Revenue is tied to energy consumption volumes distributed via the network.
