Heat from the earth's interior for the city
Geotermia Konin is a modern renewable energy source installation that has been powering the municipal heating network since 2025 and fits into the city's sustainable development strategy. The project utilizes natural geothermal resources to provide residents with ecological and stable heat, limiting pollution emissions and becoming independent of fossil fuels.
History and project development
Work on the Konin geothermal plant lasted over a decade. The company Geotermia Konin was established in 2012, and preparations for obtaining funds and developing the concept began back then. The first research-production well GT-1 was drilled in 2014–2015 on Pociejewo Island, reaching hot water from a depth of approx. 2660 m. Hydrogeological parameters confirmed high resource values and allowed for investment continuation.
Construction of the geothermal heating plant was conducted in subsequent years; its launch took place on October 27, 2025, making Konin the tenth geothermal heating installation in Poland.
Investment financing came from combining the city's and MPEC Konin company's own funds with subsidies and loans from the National Fund for Environmental Protection and Water Management and European funds.
Geothermal resources and water parameters
Hot waters under Konin come from Jurassic formations and have an exceptionally high temperature - nearly 90°C at extraction, placing them at the forefront of geothermal water parameters in Poland.
Their mineralization is also high, which poses both a challenge and an opportunity - it requires the use of resistant technological materials, but simultaneously testifies to the resource's uniqueness.
The installation utilizes a two-well "doublet" type system:
- GT-1 – production well, capturing hot water,
- GT-3 – injection well, into which cooled water is reinjected, creating a closed loop.
Modern geothermal heating plant
The geothermal heating plant in Konin has been integrated with the municipal heating system, thanks to which energy from geothermal goes directly to the local network. The facility has an installed capacity of 8.1 MW, allowing production of even approx. 159 TJ of heat annually, covering a significant part of the city's thermal energy demand.
Geothermal energy operates continuously and independently of external temperature, and the thermal system concept provides for cooperation with other sources, ensuring supply stability throughout the year.
Benefits for residents and environment
Launching geothermal means for Konin:
- lower fossil fuel consumption in heating,
- lower emissions of CO₂ and other pollutants into the atmosphere,
- improvement of air quality and residents' quality of life,
- greater energy security for the city.
The project fits into Poland's energy transformation policy and can serve as inspiration for subsequent cities wanting to use local geothermal resources in heating systems.
