A new geothermal district heating system has been inaugurated in Tremblay-en-France, just outside of Paris.
A new geothermal district heating system has been inaugurated in Tremblay-en-France, just outside of Paris earlier this week.
About 80% of the heating demand of the 10,000 inhabitants will now be covered by geothermal energy.
The project was implemented by Dalkia and Idex, through their joint subsidiary Tremblay Géothermie, for the city of Tremblay-en-France.
Geothermal energy has been utilised on the site since 1984 and has been maintained until now by SEAPFA Equipment and facilities. After 30 years of operation, it was crucial to renew the aging geothermal installations. Four months of work in the summer of 2015 resulted in the drilling of two new wells in the Dogger aquifer at a depth of 1,800 m and recovering water at 73 ° C.
The total investment cost of the project was EUR 15 million.
