A regional-scale evaluation of geothermal energy re-sources and subsurface heat-storage potential are being carried in the westernmost part of Switzerland and the nearby surrounding France (Haute-Savoie and Ain Departments) in the framework of the ‘GEo-
thermie2020’ and Swiss national SCCER SoE pro-grams. These activities are promoted by the Canton authorities and the Services Industriels de Genève.
