Geothermal pilot in Estonia starts operations

The first semi-deep geothermal pilot project developed by the Geological Survey of Estonia (EGT) has officially started operations in the Tiskre sub-district in Tallinn, Estonia. The pilot has successfully supplied heat to a large apartment building while offering valuable insights into its performance and environmental impact through ongoing research and monitoring by the EGT.

The goal of GEOENEST is to assess the potential of geothermal energy as a source for district heating solutions through several pilot solutions, each significantly different from the others. The first pilot in Taludevahe 116 utilizes heat from a 500-meter-deep borehole using a double-U pipe as a heat exchanger for a single residential building covering an area of 4360 square meters.

The initiative aligns with Estonia’s efforts to combat climate change and provide efficient heat energy solutions by potentially reducing CO2 emissions by an additional 300 tonnes annually.
