Drilling starts for geothermal heating project in Dugny and Le Bourget, France
Drilling of geothermal doublet has started for a district heating project of Groupe Coriance in the towns of Dugny and Le Bourget in Seine-Saint-Denis, France.
Drilling has started for a doublet that will supply the future geothermal heating network of the towns of Dugny and Le Bourget in the department of Seine-Saint-Denis in France. The drilling operations is expected to last from July to October 2025.
Meanwhile, construction of the heating plant has been ongoing since October 2024. Currently, four boilers have already been installed, which will be used for backup and emergency purposes. The pumps to distribute the water across the work will soon be installed. The heating plant is expected to be completed by December 2025.
The geothermal heating project is being undertaken by Dugny-Le Bourget Green Energy (Energie verte de Dugny – Le Bourget / EVDB), a wholly owned subsidiary of Groupe Coriance, as part of a Public Service Concession contract.
The EUR 55 million project is being supported by the French Environment and Energy Management Agency (ADEME) with EUR 18 million, the Ile-de-France region with EUR 2.5 million, and by the Greater Paris Metropolis with another EUR 2.5 million.
When completed, the 20-kilometer network will supply more than 9000 housing equivalents, including the Le Bourget airport. The use of geothermal for heating will help save more than 15,600 tonnes of CO2 emission per year, or the equivalent of the emissions of 13,000 cars. The facility will extract heat from the Dogger formation, at the target drilling depth of around 1700 meters. Four 2-MW heat pumps will be installed on the heating network.
