A second geothermal heating plant has been inaugurated and opened to the public by the Coriance Group in the city of Champigny-sur-Marne in France.
The Coriance Group has now officially inaugurated the second geothermal heating plant the city of Champigny-sur-Marne in the Île-de-France region of France. Although the plant had already started operations in 2024, it has now opened its doors to the public with exhibitions showcasing the plant equipment and how heat is produced from the groundwater.
Since 2016, the Coriance Group had been operating the first geothermal plant and heat network in Champigny-sur-Marne. The original heating network served the Mordacs and Bois l’Abbé districts, in the east of the city.
Plans for further expansion of the geothermal heating coverage were first reported in 2018, with Coriance being awarded the project by the Campinois Public Geothermal Establishment (L’Établissement Public Campinois de Géothermie / EPCG) in 2019. The second heating network was designed to give the residents and districts of the city access to geothermal heating.
The work to expand the district heating network began in 2022, creating 9.2 kilometers of new network in the city. Drilling of a doublet started in February 2023, targeting the Dogger Formation at 1800 meters depth. This took around four months. Construction of the new heating plant commenced after drilling and lasted for about a year.
By September 2024, the second geothermal heating network started supplying the heating needs of 5,000 homes, saving 9500 tonnes of CO2 each year, equivalent to the emissions of 7900 cars.
Elsewhere in the Greater Paris region, the Coriance Group has also started drilling work to expand geothermal heating in the commune of Alfortville, as well as for a new geothermal heating facility in the town of Garges-lès-Gonesse.
