Stadtwerke München (SWM) reports successful results from the first well drilled for its ambitious large-scale geothermal heating project within the city of Munich, Germany.

As reported by our German friends at TiefeGeothermie, the city utility of Munich, Stadtwerke München (SWM) has announced that drilling of its first well for the new planned combined heat and power plant South (HKW Süd) in Munich has been successful. Drilling took about three months.

Pumping tests at a depth of 2,800 meters produced 100 centrigrades hot water with a fill rate of more than 120 litres per second. These are better characteristics than expected. At the end of July, the drilling rig will be moved to the next drilling pad. Work on the second well will begin in early August. By the end of 2019, work on all six wells should be completed.

At HKW Süd in Thalkirchen, the most powerful geothermal heating plant in Munich is being built – and the largest geothermal plant in Germany to date. With a thermal output of 50 MWthermal and more, it is expected to deliver eco-heat for at least 80,000 Munich residents by the year 2020, as SWM announced in a press release.

SWM currently operates five geothermal plants in Munich and in the region. As part of its renewable energy expansion initiative, SWM is holistically expanding its renewable energies, both in terms of electricity and heating. Its goal is to make Munich the first major German city by 2040, in which district heating is generated 100 percent from renewable energy sources. The main contribution will be provided by geothermal energy.

The geothermal plant at HKW Süd is also the destination of the GeoTHOUR of the geothermal conference PraxsiforumGeothermie.Bayern on October 18, 2018.
