Highlights:

• The new geothermal heating plant in Konin has a capacity of 8.1 megawatts.
• The geothermal project in Konin is an example of a strategic approach to energy transition based on renewable sources.
• Investments in this type of technology contribute to greater energy independence, improved air quality and the fulfilment of international commitments to reduce greenhouse gas emissions.
• It is expected to generate as much as 159 terajoules of heat per year. This is enough to meet the energy needs of a significant part of the municipal heating network in Konin outside the heating season. 
• The investment has been supported by the National Fund for Environmental Protection and Water Management (NFEP&WM) in the amount of PLN 51.5 million (PLN 33.7 million in subsidies and PLN 17.8 million in loans).

This is an important day for Konin – 13 years after receiving the first grant, we are launching a geothermal power plant with a capacity of over 8 MW, which will supply a significant part of the municipal heating system. This is the result of long-term, cross-party cooperation, which shows that energy investments can continue despite changes in government. Geothermal energy is not only clean, accessible heat for residents, but also a boost for the development of tourism, recreation and the local economy. As the Ministry of Climate and Environment, we support such projects because they improve the quality of life and offer heat at an acceptable cost – without pollution and with benefits for the entire region

– said Paulina Hennig-Kloska, the Minister of Climate and Environment.

Benefits for residents and the climate

The geothermal project in Konin is an example of a strategic approach to energy transition based on renewable sources. The use of geothermal energy as a stable and environmentally friendly solution is in line with the priorities of the Ministry of Climate and Environment.

Investments in this type of technology contribute to greater energy independence, improved air quality and the fulfilment of international commitments to reduce greenhouse gas emissions. Independence from weather conditions and lasting public trust make geothermal energy an exceptionally valuable element of national energy policy, while supporting economic development and national security.

Konin has been associated with energy for centuries – and this will not change. Only its colour will change: to green. Energy flowing from the earth, geothermal energy, is becoming a symbol of the region's modern transformation. Eastern Greater Poland is one of the most important places on the geothermal map of Poland, with a record temperature of over 90°C at a depth of only 2,600 metres. This is a huge opportunity, but also a challenge, especially given the high salinity of the water. After years of effort, this potential is now being optimally exploited – to the benefit of residents, the environment and the country's energy future

– emphasised Deputy Minister Krzysztof Galos.

Construction spread over several years

The implementation of the geothermal project in Konin took a total of 13 years and consisted of two main investment stages. In October 2012, Geotermia Konin submitted an application for co-financing of the GT-1 production well, which, after a positive assessment by the Minister of the Environment, received support from the National Fund for Environmental Protection and Water Management.

Drilling work carried out between July 2014 and May 2015 was successful, enabling hot water to be extracted from deep underground. In May 2016, hydrogeological documentation confirming the high quality of the thermal water parameters was approved. The cost of this stage amounted to PLN 18.75 million.

The second phase of the project, implemented between 2019 and 2025, involved the construction of a heating plant and the GT-3 injection well. In June 2025, concessions were obtained for the exploitation of geothermal resources (GT-1) and their injection (GT-3), and in September, a permit for heat production was granted. The total cost of the second stage of the investment amounted to PLN 67.15 million.
