Clichy-sous-Bois and Livry-Gargan choose Arverne Group to create and operate their new low-carbon heating network

Pau, January 27, 2025 – Arverne Group (FR001400JWR8 – ARVEN) is committed to a low-carbon future with a new geothermal heating network for the towns of Clichy-sous-Bois and Livry-Gargan, in partnership with Dalkia and Ile-de-France Energies & Territoires.

Arverne Group, a major industrial player in the production of renewable underground resources, announces the signature by its subsidiary 2Gré of an ambitious contract for the creation and operation of a low-carbon geothermal heating network for the towns of Clichy-sous-Bois and Livry-Gargan.

Local, sustainable and cost-effective energy

This major project will enable residents of both towns to benefit from local, low-carbon and competitive energy. The existing network will be completely rehabilitated, while a new network will be deployed to serve new neighborhoods. By 2031, this network will extend over 26 km, with a production capacity of 115 GWh.

Significant environmental and social benefits

Thanks to the use of 91% renewable energy, this network will reduce CO2 emissions by 20,000 tons a year, equivalent to taking 10,000 vehicles off the road. From July 1, households will benefit from a reduction of almost 50% in their energy bills. The project will help lift around 1,100 households out of fuel poverty.

investment for the future

With a total investment of almost 90 million euros, borne by all the partners, with the support of ADEME and the Ile-de-France Region, operations will begin in 2025. The concession will run for a period of 30 years. 2gré, whose teams have carried out analyses of the geothermal resources of the Dogger reservoir, will also carry out engineering and deep geothermal drilling work, with Arverne Drilling Services, as well as well maintenance operations over the duration of the concession.

Arverne Group thus confirms its commitment to accelerating the energy transition by applying its expertise at the service of sustainable solutions accessible to everyone.

“ This operational collaboration with Dalkia and Ile-de-France Energies & Territoires reflects the trust placed in Arverne Group and the excellent expertise of its subsidiaries 2gré and Arverne Drilling Services. By deploying our integrated and innovative offer, we are demonstrating our ability to decarbonize local heating networks thanks to geothermal energy, a local and renewable energy that reduces CO2 emissions, while offering significant savings on energy bills for individuals, local authorities and businesses,” said Pierre Brossollet, founder and CEO of Arverne Group.
