Switzerland: Geothermal District Heating Project Starts in Geneva

Major geothermal project starts in Geneva (WRS)

A large borehole is being drilled in Satigny. It will reach 650 meters down. Geologists believe the water temperature at that depth will be around 25 to 30 degrees.

There will be a further six bores drilled in the next three years. The canton hopes the new power source will cut the use of heating oil by 53 percent.

But the holes go nowhere near the depth of the ones in Basel and Sankt Gallen which were blamed for creating small earthquakes. Those were down to a depth of around 5 km.
