Stadtwerke München (SWM), the city utility of Munich/ Germany, has completed its drilling campaign at HKW Süd, now starting a three week testing run.

After almost two years, the drilling work for the geothermal plant at HKW Süd Stadtwerke München (SWM) (Heat Plant South) is now finally completed. The last perceptible pumping attempts began on Saturday, March 14, 2020. They are scheduled to run for three weeks and are intended to show whether the yield and temperature of the thermal water deposit meet expectations, the Stadtwerke München (SWM) said.

The results of the performance tests so far have already shown that the temperature is significantly higher than expected. Based on this data, Stadtwerke is confident that the actual output of the plant will exceed the planned 50 MW thermal and that more than 80,000 Munich residents can be supplied with ecological heat.

The heating center, which will house the technology, is currently under construction next to the drilling site. After final long-term pumping trials (without steam escaping), the system should then go online in the 2021 heating season.
