As part of the annual Praxisforum Geothermie.Bayern, GeoTHOUR, an exciting field trip after the event sponsored by Turboden will provide a great opportunity to visit the geothermal plant at Holzkirchen and the geothermal district heating system in Poing all around Munich, Germany.

Experience geothermal energy and regional regenerative energy generation with the Turboden- GeoTHOUR that will visit geothermal plants in the Munich area as part of the upcoming Praxisforum Geothermie.Bayern 2019, 7-8 October 2019.

After two days of workshops and congress the participants of the 7th Praxisforum Geothermie. Bayern will again be able to obtain practical experience by visiting two geothermal plants around Munich. On 9th October this year’s Turboden-GeoTHOUR will lead to the geothermal power plant Holzkirchen and afterwards to the geothermal heating plant in Poing.

The GeoTHOUR is sponsored by the the Italian turbine manufacturer Turboden.

„Subsequent to the informative lectures and stimulating discussions during the Praxisforum Geothermie.Bayern we are pleased to give the possibility to experience geothermal plants first hand“, so Dr. Jochen Schneider, managing director of the organizer Enerchange. „Since Bavaria is a pioneer in the field of geothermal energy and with the surrounding area of Munich certainly being a geothermal hotspot, we don’t even have to drive far to reach it.”

In the morning of 9th October, the geothermal power plant in Holzkirchen will be visited. In the afternoon the excursion leads to the geothermal heat plant in Poing. An organized bus takes the participants from Munich Central Station to the geothermal plants and back again. Catering services will be provided during the GeoTHOUR.

Electricity and Heat Generation in Holzkirchen

The youngest geothermal plant in operation represents the geothermal power plant in Holzkirchen which is located 30 kilometres south of Munich. Since December 2018, it has been supplying the citizens of the community with regenerative district heating. Turboden’s ORC power plant also started its operation in July 2019. The combination of electricity and heat generation is not only an ecological but also an economic advantage: the surplus heat energy during the summer months can thus be used in a profitable way.

In terms of drilling depth and length, Holzkirchen is record holder in Germany. With a drilling length of 6,084 metres, which leads to a depth of around 5,100 metres, the second drilling of the doublet is both the longest and the deepest in Germany. With temperatures over 150 degrees Celsius, it also produces the hottest geothermal water in Germany. (here an overview by Turboden)

Geothermal District Heating in Poing

Around 20 kilometres east of Munich lies the municipality of Poing. Since its first geothermal heat extraction in June 2011, the municipality has covered its heat requirements with deep geothermal energy. With an installed heat output of ten megawatts, the geothermal plant supplies around 850 households, businesses and public buildings via a 30-kilometer district heating network and covers the basic heating load. The peak load is capped by the existing natural gas-fired block-type thermal power station. Since commissioning, geothermal energy in Poing has thus replaced fossil heat with renewable deep heat.

Additionally, the geothermal plant in Poing is one of the best monitored geothermal projects in Bavaria. Due to seismic events in 2016 and 2017, the operator Bayernwerk Natur GmbH has set up a total of five seismic monitoring stations.

Register by October 1, 2019

The registration deadline for GeoTHOUR is 1st October. The price of 250,- Euro includes transportation, food and drinks as well as the participation in the Praxisforum Lounge the evening before.

On 7th and 8th October, the Praxisforum Geothermie.Bayern will once again be offering a high-quality programme with a workshop day and a congress day. Experts from science, politics, business and operation will discuss the latest trends and developments at the geothermal industry meeting. The focus this year will include geothermal heat supply and the consequences of CO2 pricing on heat production costs.

The Praxisforum will take place at the Haus der Bayerischen Wirtschaft in Munich. Further information at or via the organizer Enerchange at
