Drilling of the wells for the planned geothermal heating system for the Olympic Vilage in Paris, France have been completed and now give way to construction of the heating plant.
Plaine Commune Energie, a subsidiary of ENGIE Solutions, announces that it has successfully completed drilling of the 11 wells that will supply the future geothermal heat plant in the Pleyel district. The drilling campaign started in January 2021 and lasted for six months, resulting in 11 boreholes including 3 producing wells and 8 reinjection wells. The depth of the wells ranges from 50 to 70 meters.
As we had previously reported, the plan is to use water at 14 degrees C to provide cooling to Ile-de-France and the Olympic Village to help withstand the effects of heat waves. Through the use of thermo-fridge pumps, geothermal water from the boreholes can be used for either heating or cooling depending on seasonal needs.
Following the successful drilling campaign, construction of the geothermal heat station will commence by 2022. Once the plant has been finalized, it will be connected to the SMIREC heating network. The Olympic Village and the entire Pleyel District will then benefit from 68% local and renewable energy. Eventually, about 609,000 square meters of buildings will be connected to the network.
A total investment of ~US$21.5 million (EUR 18.6 million ) was dedicated to the project, EUR 5.8 millions of which was subsidized by the Île-de-France Region, the ADEME Île- de-France, and SOLIDEO.
