As part of the GEOBEST-CH research project, the Swiss Seismological Service (SED) at ETH Zurich is using two additional measuring stations to monitor the hydrothermal geothermal project in Vinzel (Vaud) in the La Côte region. One aim of this monitoring is to improve knowledge about natural, local seismicity before the borehole is sunk (work will start in 2020) and the plant becomes operational. But this monitoring should also help to detect earthquakes quickly and accurately and to clarify whether they are associated with the geothermal project or are rather of natural origin.
EnergeÔ plans to implement several deep hydrothermal geothermal projects in the La Côte region. In a first phase, the geothermal projects are aimed at an aquifer in Middle-Jurassic limestone, which are expected to be reached at a depth of approximately 2’300 m, and fault zones therein. EnergeÔ expects to encounter thermal water with a temperature of 80°C and to reach production rates between 30 l/s and 70 l/s.
