Summary

Groupe Coriance has started drilling for a geothermal heating project to serve Chatenay-Malabry and Plessis-Robinson communes in Paris, France.

The Coriance Group, through subsidiary Reseau Terra Confort, has announced the start of drilling for a geothermal heating system to serve the communes of Plessis-Robinson and Chatenay-Malabry, part of the Greater Paris Area in France. The drilling work is expected to be completed by January 2026, and the commissioning of the geothermal system is planned by Spring of the same year.

The plan is to drill to a depth of 1600 to 1700 meters, where geothermal waters at 68 °C are expected. This will then be supplied to a heating plant, where the heat will be recovered to supply the urban heating network. This will allow the network to supply up to 15,000 homes with 88% renewable energy, thus reinforcing the commitment of the two municipalities to a sustainable energy transition.
