Abstract
During the current time period only one new geothermal project was carried out in Austria. For the very successful Frutura project (highest production temperature in Austria so far) two deep geothermal boreholes have been drilled in the Styrian Basin in 2014 with a total length of 6.5 km for the thermal heat supply of greenhouses.
The electrical power production from geothermal declined in general. The ORC unit at Simbach-Braunau has been dismantled.
The city of Vienna is currently developing a comprehensive exploration concept for hydrogeothermal utilization in the greater Vienna area. Resuming of drilling operations is not expected before 2020.
The number of ground source heat pumps still shows a steady increase. The total number of units based on DHE is estimated as high as 70,000 having a capacity of 840 MWth and 1,386 GWh/yr based on sale figures provided by heat pump suppliers.
