A 20-kilometer geothermal heat network is planned to be deployed in the communes of Pantin, Les Lilas, and Pré-Saint-Gervais in Paris between 2024 and 2026. This will supply heating and hot water to condominiums, social housing, and public facilities and will save about 28,000 tons of CO2 emissions per year, or equivalent to the emissions of 19,000 cars.
