Germany - Electricity Generation

In the country only Organic Rankine and Kalina cycle techniques are applied, mainly in conjunction with district heating system, for geothermal power production, due to the lack of high enthalpy resources at shallow depth. Several new 5 MWe power plants have been commissioned, resulting in a total installed capacity of 27.1 MWe in Germany. the Federal Government is supporting the geothermal development through funding R&D projects and with the very generous new feed-in tariff, increased to 0.25 €/kWh. The majority of the projects is in Bayern (20 MWe) and Rheinland-Pfalz (7 MWe) (Weber, et al., 2015).

Development since WGC2010: 20 MWe in four new units: Dürrnhaar, Kirchstockach, Insheim and Sauerlach.

Installed capacity 27 MWe                      
Geothermal Electricity 35 GWh/y

Installed geothermal generating capacity (December 2009) in MW

Landau0.23

 Germany is not blessed by high-enthalpy reservoirs. Its electricity production, strongly supported by local administration and central government, is limited to binary plant applications, with massive utilization of the hot water for district heating.

The first geothermal plant for electrical power generation in Germany is at Neustadt- Glewe, with an installed capacity of about 230 kW with a binary cycle using 98°C geothermal fluid. In addition 10.7 MWth are used for district and space heating. 
Two new plants in Landau and Unterhaching started in 2008, each with a capacity of about 3 MW, and an heating capacity of about 3.5 and 38 MWh respectively.

Additional projects for further installation of 10 MW are planned in several sites. For a minimum of at least three projects (Hagenbach/Upper Rhine Graben and two in the Munich region) drilling works are already scheduled. Construction has also started on the biomass/geothermal energy hybrid plant at Neuried (Upper Rhine Graben). Research activities at the EGS R&D site at Groß Schöneck are ongoing.
