Kalisz, a city in Poland, is preparing to launch exploratory drilling for geothermal resources by early 2025. This project aims to harness thermal water to provide heating for both municipal and residential buildings and supply recreational facilities in the area.
The initiative has gained momentum following the signing of funding agreements with the National Fund for Environmental Protection and Water Management (NFOSiGW) and six other municipalities. Through this funding, Kalisz will receive PLN 15 million (around USD 3.72 million) to support the geothermal drilling efforts.
The exploratory well in Kalisz will be drilled as a vertical borehole near Sportowa Street, Wal Jagiellonski, and the Swedrnia River, reaching a depth of 1,700 meters. Following the drilling, the project will conduct hydrogeological, geophysical, and laboratory tests to confirm the site’s viability, with full hydrogeological documentation anticipated by 2026.
Experts suggest that Kalisz‘s geothermal resources may offer higher temperatures compared to Uniejow and Poddebice, cities where geothermal heating has successfully operated for several years. Mayor Krystian Kinastowski highlighted the potential of this clean energy source, stating, “Geothermal energy offers affordable heating solutions for Kalisz residents and will benefit both current and future housing developments.”
The geothermal project is expected to provide not only cost-effective energy but also to stimulate economic growth, contributing significantly to Kalisz’s development.
