Deployment of the new heating network and its two substations - ZAC des Groues

Feb 1, 2022 - Aug 31, 2023

The ZAC des Groues project involves extending the existing heating network supplying La Défense to serve the new buildings. The connection of the operation has also made it possible to initiate the greening of the entire network, whose energy mix will reach 50% renewable energy by the end of the year. Work on the deployment of this new network began at the beginning of 2022 with the construction of two substations in parallel. The aim is to be able to supply heating to the first building lots in the ZAC as soon as they are completed.

Location: one in the southern sector (Garenne) and one in the northern sector (Hanriot)
Start: February 2022
End: 3rd quarter 2023
