The drilling of a new geothermal doublet in Alfortville, France has officially commenced.
The Coriance Group has officially commenced the drilling of a new geothermal doublet in the Alfortville area, located in the suburbs of Paris, France. The new wells will aim for the Dogger formation at a depth of 1600 meters, where water temperatures of 73 °C are anticipated. This drilling process is expected to take around three months, with commissioning slated for September 2025.
Present at the inauguration ceremony were Luc Carvounas, the Mayor of Alfortville, and Yves Lederer, the President of Coriance Group.
In July 2023, the Coriance Group was hired by Alfortville to develop a new geothermal doublet to replace the old one that has been operational since 1986. This initiative aims to ensure the ongoing production of renewable heat and enhance the city’s energy autonomy by fulfilling 85% of the energy requirements for the city’s heating network.
This project, which necessitates an investment of EUR 22.25 million, is backed by a EUR 7.3 million grant from the French Environment and Energy Management Agency (ADEME) and EUR 2.6 million from the Ile-de-France region.
The Greater Paris Area has been harnessing geothermal energy for heating since the 1960s, primarily using the Dogger Formation as the main aquifer for geothermal energy extraction. According to a report from the AFPG, heat generated from deep geothermal resources serves about 1 million residents in France, contributing approximately 2.26 TWh to energy production in 2023. In the Paris Basin alone, there are 55 deep geothermal heating operations that produce over 1900 GWh of heat annually.
