Heating supply to a district in Potsdam, Germany has now been converted to geothermal energy from the facility developed by local utility EWP.
An entire district in Potsdam, Germany, equivalent to around 340 apartments, has converted to district heating using geothermal energy, supplied by the facility at Heinrich-Mann-Allee developed by utility company Energie und Wasser Potsdam (EWP). Work on a second section is ongoing, and is expected to start supplying Potsdam’s district heating network by the end of 2027.
The initial plan to convert district heating in Potsdam from the current combined heat and power (CHP) plant to geothermal was first reported back in 2019. By early 2023, the drilling of the first well was underway. With an output of 4 MW, the results of the first production drilling were much better than the expected 2 MW. Thus, EWP invested an addition EUR 10 million to upscale the plans for surface facilities, especially the energy centre.
At 4 MW capacity, the geothermal heating plant can supply the heat demand of almost 7000 households.
Furthermore, EWP has plans to additional deep geothermal heating plants in Babelsberg and the Potsdam-Süd industrial area. According to a recent project presentation, the planned projects are “close to starting construction.”
