Exploration of geothermal resource in Lódz, Poland by Innargi and Veolia Energia Lódz will commence with a seismic survey that will start by 11 August 2025.
By the 11th of August 2025, seismic surveys will begin to create a detailed map of the subsurface in the city of Lódz in Poland. This will be in aid of characterizing the potential geothermal resource in the area which is being developed for a district heating project.
Vibro-trucks will be traveling along designated routes to send vibrations into the earth for 20 seconds. Vibrations will then be picked up by geophones placed in advance along the routes. Operations will be done mainly in the evening and night hours. The survey will take approximately 4 weeks and cover approximately 186 kilometers.
Research on the potential of geothermal energy in Lódz is being done by a cooperation between Danish geothermal developer Innargi with local company Veolia Energia Lódz. The letter of intent to launch a joint geothermal exploration campaign was signed between the two parties in late 2024.
The geothermal project is part of Veolia’s long-term strategy to decarbonize the Lódz district heating system, including through the development of renewable energy sources. Veolia and Innargi estimate that geothermal energy could provide up to 200 MW of installed capacity, covering about 15% of the current thermal capacity of the Lódz district heating system. However, such development will depend on several factors, including the need to meet legal and procedural requirements for this type of investment.
