Early November saw work begin on installing the Rosny-sous-Bois and Noisy-le-Sec shared geothermal district heating network. Led by GDF SUEZ subsidiary company Cofely Réseaux, YGéo is an ambitious long-term project designed to meet the space heating and domestic hot water needs of around 10,000 home equivalents from 2016 onwards.
Just under a year from the decision of the SIPPEREC (Syndicat Intercommunal de la Périphérie de Paris pour l’Énergie et les Réseaux de Communication) committee to award the public service outsourcing contract to GDF SUEZ Energie Services subsidiary company Cofely Réseaux, work on the new geothermal solution for Rosny-sous-Bois and Noisy-le-Sec is underway.
The YGéo project will include a 10MW flueless geothermal plant seamlessly integrated into the local urban landscape, as well as heat pumps rated at 7 MW. The 10 km supply network will provide sufficient space heating and domestic hot water for around 10,000 home equivalents from summer 2016 onwards.
The use of geothermal energy will increase the proportion of renewables in the energy mix to more than 60%, saving users 5.5% VAT on their energy bills. This commitment to sustainability forms part of a wider program of energy transition initiated by the two towns and the wider Paris Region. The regional authority is funding the €33 million cost of the project in conjunction with ADEME, the French Environment and Energy Management Agency.
Signed in January 2014, this 30-year public service outsourcing contract provides for drilling operations to begin in the first quarter of 2015, followed by network infrastructure installation and heating plant construction in the second quarter of the year.
