On 11 August 2025, Innargi and Geofizyka Torun will begin seismic surveys to assess the potential of geothermal resources in Lódz and the surrounding area. Geothermal energy could provide up to approximately 200 MW of energy per year.
In the first half of August, seismic surveys will begin in Lódz to provide information on the geothermal potential of the city and its surroundings. The research is part of a project launched in October 2024 by Veolia Energia Polska, Veolia Energia Lódz, the City of Lódz and Innargi. Its aim is to use renewable geothermal energy in the Lódz district heating system. The research will provide detailed knowledge that will form the basis for further work on this project.
Deep underground, there is hot water that can be extracted to the surface for use in the city’s heating system. This energy source is called geothermal energy, and existing data indicates that its potential in Lódz is significant. To verify this, Innargi, a company specialising in the development of geothermal projects, will conduct seismic surveys in Lódz along a route of approximately 160 kilometres. They will begin on 11 August.
“We are delighted to be taking another step towards harnessing the potential of geothermal energy for district heating in Lódz. We already know that Lódz, like the rest of Poland, has good conditions for using this stable and natural source of energy. Seismic surveys will give us more detailed knowledge about the structure beneath the earth’s surface. They will also allow us to check where faults occur, how deep the geothermal water is and what its temperature is.“
Samir Abboud, CEO at Innargi
The seismic surveys are a continuation of the strategic partnership announced last October between Veolia, Innargi and the City of Lódz.
“For Veolia, the decarbonisation of the Lódz heating system, based in part on renewable energy sources, is of key importance. The introduction of geothermal energy into our fuel mix will be an important step in the implementation of our green transition strategy. The cooperation with Innargi will allow us to assess the potential of geothermal sources in our city in the first stage, and then the scale of their application for heating purposes within the district heating system managed by Veolia. Geothermal energy, as a renewable energy source, always has a significant impact on reducing CO2 emissions and thus on meeting the environmental challenges facing the energy sector in Poland.“
Anna Kedziora-Szwagrzak, President of the Management Board and CEO of Veolia Energia Lódz
“The start of seismic surveys is an important moment for Lódz and our residents. The surveys that are just beginning may open up completely new opportunities for us in terms of using our city’s natural resources. Geothermal energy is not only clean, local energy, but also an opportunity for greater energy independence and security of heat supply for the residents of Lódz. We are convinced that investing in renewable energy sources is the best way to build a modern, environmentally friendly city. It is also an important step towards achieving the goal we have set for ourselves – climate neutrality. Cooperation with experienced partners such as Veolia and Innargi gives us confidence that the project will be carried out professionally and to the highest standards. Thanks to this, Lódz can be a pioneer in the use of geothermal energy on such a large scale.”
