Public service delegation in district heating and cooling
Coriance operates in the field of district heating, proposing solutions to primary heating networks, ie installations (geothermal, cogeneration, boilers etc.) for the production and delivery of energy to buildings and residences. In this area, the company specializes in renewable energy and therefore offers its customers the use of biomass, geothermal energy, energy recovery techniques or cogeneration as energy sources.
Energetic efficiency
Coriance is a leading provider of energy efficiency services, with the company working at 3 levels:
1. Supplying cost-optimized sustainable energy
2. Operating and maintaining heating and cooling installations
3. Carrying out maintenance, renewal or renovation work
60% of the energy supplied by Coriance therefore comes from renewable energy and over 80% of the heat is produced by green energy sources. In mid-2013, the energy mix was composed of the following:
• 26% biomass
• 21% of cogeneration
• 19% gas
• 18% of geothermal energy
