The Holzkirchen geothermal heat and power plant has been nominated for an architectural award for wooden structures in the regions of Tyrol and Salzburg/ Austria and Bavaria/ Germany.

This year saw the nomination of the geothermal heat and power plant of Holzkirchen near Munich in Germany for an architectural prize, and to the best of our knowledge the first time a geothermal plant has been nominated. A cross-regional architectural/ construction prize for wooden structures, the Rosenheimer Holzbaupreis is open for projects in the neighbouring regions of Tyrol/ Austria, Salzburg/ Austria and large parts of Bavaria/ Germany (Rosenheimer Holzbaupreis) taking place every four years.

The geothermal plant was built in the town of Holzkirchen between 2016 and 2019. From a depth of approximately 5,100 meters, geothermal energy is now derived by the municipality as an environmentally friendly energy source for heating.

Thermal water serves as an energy source, flowing through a limestone layer around 500 m thick in the deep underground beneath wooden churches. In Holzkirchen there are currently the deepest hydrothermal geothermal wells in all of Central Europe.
With a thermal water delivery rate of approx. 55 liters per second, in combination with the delivery temperatures of approx. 150 degrees C, a geothermal output of 24 MW from the Holzkirchen geothermal energy can be provided. The main part of this heat is used to supply the district heating network, the other part to generate electricity in an ORC power plant with an electrical output of 4.2 MW.
