Project: Poznan, Poland
Geothermal in Poznań
Innargi has entered into an agreement with Veolia Energia Polska and Veolia Energia Poznań about exploring the potential for geothermal energy for district heating in Poznan. The project is aimed at decarbonizing district heating and is in line with Veolia’s mission to be the benchmark company for ecological transformation.
The Poznań project will be the first in Poland on this scale to use geothermal energy to produce heat to supply the city’s district heating system. Veolia Energia Poznań estimates that the heat obtained from the geothermal plants could provide up to 20% of the city’s district heating system needs. Current plans call for geothermal energy to feed the grid in 2029.
Current status
Existing data indicate that the potential for geothermal energy in Poznań is significant. To definitively verify the analysis and proceed with design work, Innargi will conduct seismic surveys in Poznań in March 2025. The results of the geologists’ work will provide detailed knowledge on the further development of the Poznań geothermal project.
