THE CUSTOMER

SWM is successfully expanding its development both in the electricity and heat renewable energies sectors. The most recent additions to the SWM Sauerlach power plant are two geothermal plants in Dürrnhaar and Kirchstockach. These plants realized by Turboden are in operation since 2012 in the south of Munich. The two power stations have an overall electrical output of 11 megawatts. They are technically comparable to the geothermal power plant of SWM in Sauerlach. SWM has become leader of geothermal power in Germany, thanks to many years of operating experience and successful results. SWM has acquired the two power stations from HOCHTIEF PPP Solutions GmbH and BayWa r.e. Renewable energy GmbH, a subsidiary of BayWa AG, which implemented and operated the plants until 2016.

THE NEED

Production of base load electricity and heat from renewable resource. A submersed sea, the Molasse basin, stretches over a length of 1000 kilometers along the axis of the Alps, from France to southern Germany. Geothermal water available at 4 to 5 km depth can be extracted to produce electricity and heat for households.

OUR SOLUTION

Turboden has been awarded a 5 MWe geothermal power plant based on the most optimized solution in terms of: maximized efficiency, minimized noise emissions and space occupation. The plant is an unique example of architectural integration of a powerplant with a building, with the turbogenerator indoor, and the dissipation system on the roof. The plant is capable of island mode operation to feed the close municipality with highly available heat.
