The GRETA WebGIS “Geothermal potential - Saalbach” identifies the closed-loop (CL) geothermal potential estimation of the municipalities of Saalbach and Leogang, and the open-loop (OL) geothermal potential estimation of the two valley bottoms of these municipalities.

The CL geothermal potential is expressed as the sustainably exchangeable energy (MWh/y) by a single 100m long borehole heat exchanger.

The OL potential is based on the maximum yield extractable from a single well, indicated as technical volume flow. The different yield values were calculated according to two different doublet well distances: 10 and 100m. The OL geothermal power layers represent the maximum exchangeable power of a single well doublet. It is based on the aforementioned yield, and calculated according to a groundwater temperature drop of 5°C. The OL geothermal potential represents the annual amount of energy extractable for a 2000 hours full load heating period, and is expressed in Megawatt-hours.

The other layers available were used for the geothermal potential estimation.
