Drilling work has started since November 2023 for the first geothermal research well GT-1 in ul. Gdanska in Gniezno, Poland. The research well will serve to validate the temperature and productivity of the inferred geothermal reservoir and will inform future plans for the project.

The Gniezno Municipal Office stated that the target depth of the GT-1 well is approximately 2100 meters depth, where an aquifer with fluids at 75 °C is expected. This resource will then be sufficient for heating. If higher temperatures are encountered, then recreational applications will be considered. Should the GT-1 well be evaluated as suitable for heat supply, a decision will be made to drill a second well for reinjection.

In 2021, Gniezno was one of the few territories selected by the National Fund for Environmental Protection and Water Management for funding under the “Providing access to thermal waters in Poland” program. The city obtained almost PLN 17 million (ca. USD 4.4 million) which will be enough to cover the exploratory drilling stage.

The thermal waters grant program of Poland has substantially accelerated the development of several geothermal projects. Very recently, the town of Zyrardow kicked off the drilling of a 3-km geothermal well. Similar efforts are being undertaken in in Krakow, Sochachzew, and Otwock, following the announcement of a second round of grants under the thermal waters program.
