In Champigny-sur-Marne, a municipality in the southwest of the capital of France, Paris, the Coriance Group wins contract for the creation of a second geothermal heat network. (location)

As a forerunner in the field of geothermal energy, Champigny-sur-Marne chose in the early 1980s to use this renewable and local energy. Since 2016, the Coriance Group has been operating the city’s first geothermal plant and heat network. More than 7,000 housing equivalents are already supplied with heating and hot water.
