Tapping into natural heat from 1,500 meters underground, this facility marks a key milestone in the local energy transition. The heating network of Parly 2, Europe's largest residential complex, now incorporates 75% geothermal energy, reducing its reliance on volatile gas prices.
The 35 million euro project is supported by ENGIE, the Yvelines Department, the City of Le Chesnay-Rocquencourt, and the residential complex, with state funding via ADEME's Heat Fund. Beyond the residential units, the network serves the André-Mignot hospital, Guynemer school, Charles-Péguy middle school, the municipal swimming pool, and the town hall.
“"The energy transition must produce concrete results for the residents."
The initiative will continue with the VerdY project, led by the Yvelines Department, which aims to extend renewable heat distribution to five municipalities by 2028: Le Chesnay-Rocquencourt, La Celle-Saint-Cloud, Noisy-le-Roi, Bailly, and Bougival.
