Drilling in Kiskunhalas, Hungary reaches geothermal reservoir ahead of target depth
Drilling of the first well for a planned geothermal power and heat project in Kiskunhalas, Hungary has been completed ahead of the target depth.
Drilling of a well for a future geothermal heat and power project in Kiskunhalas, Hungary has reached the target reservoir at a depth of 1940 meters, ahead of the target 2400 meters. Plans already underway for the drilling of a second well.
Construction work for the geothermal drilling project in Kiskunhalas was started in March 2026, while drilling commenced by May. This will be the first geothermal project of MVM Zöld Generáció Zrt (MVM Green Generation), a subsidiary of Hungarian power company MVM Group. Drilling work was done by local company Rotaqua using a drilling rig from Italian company DRILLMEC.
The well has an expected flowrate of 100 L/s, and the thermal waters at depth are expected to have temperatures of 140-150 °C. If measurements confirm this figure, drilling of the second well will proceed. The wells will be used to supply a power plant with an installed capacity of 3.5 to 4.5 MWe. The heat will then be supplied to the district heating system of nearby Kiskunhalas. Local business, industrial players, and public institutions may also join the heating system.
According to Sándor Tiszavári, Technical Director of Rotaqua, the early success was primarily due to highly favourable geological conditions and the exceptional efficiency of the advanced drilling technology deployed. The integration of the AI-DEEP platform with the drilling rig allows for real-time data analysis and automated adjustments, reducing drilling risks, optimizing penetration rates and ensuring unprecedented safety standards compared to legacy systems.
Before the end of 2025, MVM announced an HUF 8 billion (around EUR 21 million) investment for geothermal drilling and well testing work that will be done across several sites over the next three years.
Both MVM Group and Rotaqua will be featured participants at the upcoming Budapest Geothermal Energy Summit, taking place on 14 September 2026. Early bird registration for the event is open.
