Collaboration on geothermal heating development in Champs-sur-Marne

Alexander Richter 30 Apr 2019

A collaboration agreement was signed by Engie and the municipality of Paris-Vallée de la Marne for the development of a planned geothermal heating system in Champs-sur-Marne.

To ensure the deployment of geothermal energy in the municipalities of Champs-sur-Marne and Noisiel, Paul Miguel, president of the Paris-Vallée de la Marne Agglomeration Community, and Pierre Hourcade, General Manager of Engie Réseaux, signed a public service concession at the Agglomeration Hotel.

In 2015, the Agglomeration launched a study for the development of deep geothermal energy in the municipalities of Champs-sur-Marne and Noisiel. This survey confirmed the interest of the exploitation of this network, notably in the framework of the deployment of the future projects of the territory: the Aquatic Center in Champs-sur-Marne, located in the heart of the Cité Descartes, cluster of the Sustainable City ; the densification of the concerted development zones around the departmental road 199, which crosses Noisiel and Champs-sur-Marne; and concerted development projects under the responsibility of EpaMarne.

The Community Council has chosen to entrust Engie Réseaux with the public service delegation for the construction and operation of this heat network, for a period of 25 years. According to the Agglomeration, the investments needed to carry out the project have been estimated at around 37 to 39 million euros excluding tax.

A specialist in deep geothermal energy, Engie Réseaux currently supplies  25% of geothermal heat in Île-de-France, and operates 10 geothermal heat networks that supply the equivalent of 60,000 homes.

The agglomeration indicates “bet on geothermal energy for a long time”. In fact, two geothermal heat networks have already been built in Chelles (6,000 equivalent housing units) and Lognes-Torcy (85% geothermal, 5,500 home equivalents). .

Also, the future heating network in Champs-sur-Marne and Noisiel has a potential for significant energy consumption estimated at around 96 GWh by 2030.

The deployment of geothermal energy is fully in line with the desire of Paris-Vallée de la Marne to act for the energy transition and sustainable development, within the framework of the Climate-Air-Territorial Energy Plan (PCAET) currently under way. development.
