The town of Taverny, on the outskirts of Paris, plans to extend its geothermal heating network

The municipality of Taverny, in the north-western suburb of the French capital Paris in France, has announced the renewal of its contract with the company Idex for the operation of heating in the Red Cross district. Geothermal energy is at the heart of this contract, as reported The gazette of Val d’Oise.

By decision of the municipal council of June 24, the City of Taverny (Val-d’Oise) renewed its confidence in Idex for the realization of a new geothermal energy and the operation of the district heating network of the Red Cross, located around the Jean-Bouin stadium, rue Pierre-de-Coubertin.

According to Idex, the new 15-year contract should make it possible to develop a “more virtuous” network with “controlled” energy consumption.

A “virtuous” energy

Created in the 1970s, at the same time as the Red Cross district, the network was historically fueled by oil. In 2008, the site was renovated to switch to natural gas and since 2016, the purchase of biomethane has enabled subscribers to benefit from 5.5% VAT on the entire energy bill.

Network created in the 1970s

“The town of Taverny is thus continuing its energy transition with local and renewable energy: geothermal energy”, welcomes Idex, which speaks of energy naturally present in the subsoil of the Ile-de-France region, ” which emits very little greenhouse gas. . “And which, coupled with a heat pump, would offer“ interesting performance ”.

Important work

In order to make the installations compatible with this new energy, Idex will carry out major work in the substations. Test drilling will take place shortly to determine the technical characteristics of the production and reinjection wells.

27% geothermal energy to supply the network in 2022

From 2022, the network will therefore be supplied up to 27% by geothermal energy, with an additional 34% by biomethane. The additional needs will be met thanks to the current production of gas which will have been modernized.

Ademe scholarships

“While today, the Taverny heating network provides thermal comfort to more than 1,250 housing equivalents in the Croix-Rouge district for their heating and domestic hot water needs, the contract provides for an extension of the network with connection gymnasiums and the Jean-Bouin stadium. », Underlines Idex, which should benefit from subsidies from Ademe (French Environment and Energy Management Agency).

Crowdfunding campaign

A crowdfunding campaign will also be launched with the City so that residents are “the first players in this local and virtuous economy”.
