Wedoany.com Report-Mar 14, The city of Poznan in the western part of Poland is taking a major step toward geothermal district heating, as seismic surveys were started on March 11, 2025 to assess the city’s subsurface potential. The initiative is led by Danish geothermal developer Innargi and Veolia Energia Poznan, in partnership with the City of Poznan, as part of a long-term plan to integrate geothermal energy into the city’s heating system. We previously reported on the MOU between Innargi and Veolia Energia.

Seismic surveys to map geothermal potential
The surveys will cover 60 kilometers across central and southern Poznan, using specialized trucks to send low-frequency vibrations into the ground. These vibrations, recorded by geophones, will help create a detailed geological map to confirm geothermal water availability.
“The surveys will give us a better understanding of the hot water reservoirs beneath Poznan, allowing us to plan the project more effectively,” said Samir Abboud, CEO of Innargi.
Geothermal: a key part of Poznan’s energy transition
The geothermal initiative aligns with Poznan’s goal to decarbonize district heating by 2030, reducing reliance on coal. If successful, geothermal energy could provide up to 20% of the city’s heating needs, with integration planned by 2029.
“Our strategic goal is to decarbonize Poznan‘s district heating system by 2030, i.e. to move away from the use of coal to generate heat and electricity. One of the projects to help us achieve this is the use of geothermal deposits for district heating in cooperation with our partner Innargi. Heat from inside the earth, which is a renewable energy source, has the potential to become part of our green energy mix. This is in line with our vision for the future of district heating, which goes hand in hand with the green future of the city and the continuous improvement of the environment and air quality.” so Jakub Patalas, President of Veolia Energia Poznan.
A Model for Sustainable Urban Heating
Poznan’s geothermal project could serve as a blueprint for other Polish cities, reinforcing the role of renewable heat sources in modern district heating networks.
With ongoing collaboration between Innargi, Veolia Energia Poznan, and the city, Poznan is moving closer to a cleaner, more sustainable energy future.
