Summary

The Champs-sur-Marne geothermal district heating project in the greater Paris area of France has successfully concluded its drilling campaign and confirmed the resources with construction for the heating plant now underway.

The urban community of Paris – Vallée de la Marne (CAPVM) and GéoMarne have announced that they have successfully completed the strategic phase of the Champs-sur-Marne geothermal drilling campaign, which began in early December 2019.

The objective of the campaign was to reach a depth of 1,900 m to benefit from water that will ultimately provide entirely green heat sufficient to heat the equivalent of 10,000 homes in the municipalities of Champs-sur-Marne and Noisiel in the greater Paris area of France..

After three months of work in the heart of the Descartes city of Champs-sur-Marne, the GéoMarne teams have successfully finalized two deviated 1,900 m wells.

ENGIE Solutions is now able to confirm the geothermal resource in terms of flow and temperature: water at 70 degrees Celsius will be drawn with a flow of 350 cubic m/ h, data in accordance with studies previously carried out by geoscience experts.

Innovative, these wells have enabled the installation of casing with smooth fittings allowing the production parameters of the wells to be increased.

The end of the drilling and the conclusive tests carried out since then make it possible to start construction of the network and the layout of the supply substations to connect future subscribers to the heating network in a few weeks. Without forgetting, during 2020, the start of construction of the geothermal heating plant and the installation of its equipment, in order to ensure the supply of heat by the end of 2021.

This is a territorial project supported by ADEME and the Ile-de-France Region.

This district heating network to be fed by 82% with geothermal energy represents an investment of EUR 40 million. The Ile-de-France region is supporting this project with EUR 4 million, or 10% of the investment, fully transferred to the benefit of customers who benefit from a reduction in the price of heat. This support is part of the implementation of the regional energy-climate strategy which, by choosing an ambitious scenario, has chosen an objective of multiplying the production of renewable energy with geothermal energy by a factor of 3.5 compared to the 2015 production.
