Deep geothermal energy has by far the greatest theoretical potential of the locally sourced, climate-friendly new renewable energies in Switzerland.
Within Geo-Energie Suisse AG, the shareholders are pooling their expertise and resources for the development of this young technology, thus creating a common basis for broadly supporting the economic and technical risks. Geo-Energie Suisse AG's main objective is to develop pilot projects in order to demonstrate the technical feasibility of deep geothermal power plants in the medium term and their economic viability in the long term.

AEW Energie AG is joining Geo-Energie Jura SA as a further shareholder, thereby strengthening the deep geothermal pilot project in Haute-Sorne in the Jura region. This climate-neutral technology is a cornerstone of the Energy Strategy 2050+ and is set to supply electricity and heat throughout Switzerland in future.

AEW is investing in deep geothermal energy in the knowledge that Switzerland’s largest energy source lies directly beneath our feet. This strengthens support for the Swiss flagship project in the municipality of Haute-Sorne in the canton of Jura.
AEW has recognised the opportunities offered by deep geothermal energy and the significant potential presented by its imminent scaling-up and market readiness. It is considering applying this technology in its own supply area in future to provide the population with electricity and heat. The government of the canton of Aargau decided several years ago to create favourable framework conditions for the use of deep geothermal energy. The timing for entry into the market is favourable, as drilling technology has made enormous progress in recent years, significantly improving the economic viability of geothermal plants.
