In the future, Vaud will increasingly rely on energy from geothermal energy. The government estimates that by 2050 around 20 geothermal power plants will be built in the canton. The new cadastre lists 43 communities in the Canton Vaud with geothermal potential.
Currently, two projects are well advanced in the canton. In Vinzel, near Nyon, the project company EnergeÔ, in which Romande Energie also holds a stake, plans to realize a geothermal project for 1,500 households by 2021/2022.
It is planned to drill down to a depth of 2200 meters. This is half as deep as in Basel or St. Gallen, where boreholes caused several smaller earthquakes in 2006 and 2013, respectively.
The AGEPP project in Lavey-les-Bains in the Rhone Valley aims to pump the deep groundwater out of the very permeable rock and use it for the permanent power supply of around 900 households. Commissioning is planned for 2020.
These two geothermal projects are the first two in Switzerland to receive a federal financial contribution. Others are still in the development phase.
