Drilling has commenced for the inaugural geothermal well in Koluszki, Poland.
Drilling has begun for the first geothermal well (Koluszki GT-1) in Koluszki, Poland, with plans to utilize it for recreational or medicinal purposes. The drilling contract with ALGEO outlines that the work should be finished by February 2026.
The idea for geothermal baths in Koluszki was first announced in 2023, alongside considerations for district heating. Studies by the Polish Geological Survey indicate that the site's geothermal resource has a temperature of 42 °C. The current well aims to reach a depth of 1450 meters, targeting Lower Jurassic strata. Geologist Dr. Bogdan Nada anticipates a temperature of at least 40 °C at this depth, though warmer resources could also be possible.
The drilling cost is PLN 12 million. Koluszki was chosen for funding from the National Fund for Environmental Protection and Water Management (NFOSiGW) at the end of 2024, receiving a grant of PLN 10.6 million for geothermal exploration.
Zbigniew Der?gowski from the project contractor stated, “The work is progressing faster than expected, and it’s possible we’ll even finish it ahead of schedule. The drilling rig we’re using comes from Canada – it’s proven equipment that allows for precise drilling.”
If the exploration well validates the geologists' predictions, the hot water could be used for a thermal pool and may also provide heating for homes, schools, and other public buildings.
