Poland's Banska PGP-4 project in Szaflary aims to become the world's deepest geothermal well, potentially supplying one-third of the nation's heating demand. However, the project is facing delays due to the current government's preference for nuclear and renewable sources like wind and solar over geothermal energy.

Despite this, initial tests of the well, completed in April 2025, revealed temperatures around 120 °C and flow rates of up to 400 cubic meters per hour, exceeding expectations. Drilling began in April 2023 but was halted at 6103.2 meters due to technical issues. The discovery of a new aquifer at 5000 meters may allow for future electricity production, marking a significant development in Poland's energy landscape.
