Pfalzwerke geofuture GmbH, founded in 2009, is a wholly-owned subsidiary of PFALZWERKE AKTIENGESELLSCHAFT. The main task of the company is the promotion of geothermal energy in the Upper Rhine Graben. To this end, Pfalzwerke geofuture GmbH has built a deep geothermal power plant at the Insheim site in southern Palatinate. The company is also the operator of the power plant. The plant uses an ORC plant for power generation. The residual heat generated during this process can be used for local heating supply.
The power plant with a maximum electrical output of 4.8 megawatts is capable of supplying up to 8,000 households with electrical energy at around 8,000 operating hours per year. The energy of the thermal water has the potential to supply up to 800 additional households with heat.
In terms of operation conditions and problems related to incomplete knowledge of fluid properties as targeted by the call, Insheim can be considered as representative for mid-enthalpy geothermal systems in the Upper Rhine Graben, Europe’s prime area of EGS-type geothermal R&D.
Involvement in the project:
Geothermal Power Plant owner and one of the demo site providers.
