A renewable heating network for three eco-districts of Rosny-sous-Bois and Montreuil

Commissioned in 2016, this network powered by geothermal energy is part of the common desire of the three cities and of SIPPEREC (Syndicat intercommunal de la periphery de Paris pour les energies et les communication networks) to develop the use of renewable energies. south of Seine-Saint-Denis. This production plant has also benefited from financial support from ADEME and the Île-de-France region.

The year 2021 marks a major step forward in the development of this network, which is more than 75% supplied by geothermal energy, a local and renewable energy. Indeed, three booming zones in this territory have opted for carbon-free heat produced by the YGéo power plant:

• The Mare Huguet ZAC in Rosny-sous-Bois, whose last connection is in progress. This former railway wasteland converted into an eco-district displays several “green” assets, to which is added the choice of geothermal energy as a heating solution. This extension allows more than 900 housing equivalents to benefit from this natural and locally produced resource.
• ZAC Coteaux-Beauclair in Rosny-sous-Bois has also chosen this renewable heat. It represents an extension of 95.000 m² and nearly 1.400 housing equivalents for the YGéo heating network. Two thirds of the connections planned in this eco-district have already been contracted for commissioning which will begin in 2022 until 2023.
• Finally, the ZAC Boissière-Acacia in Montreuil, finalized in 2019, has recently been connected to the YGéo heating network. This area, completely renewed to give meaning to a landlocked sector, represents more than 100.000 m² of surface area and 1 housing equivalents supplied with heating and domestic hot water by geothermal energy.

The YGéo heating network thus becomes a real lever of energy transition for this booming territory. It offers citizens the opportunity to access clean, local energy, while constituting a preferred heating solution for these new Concerted Development Zones, designed to promote well-living in the city.
