Development and expansion plans for the Turawell geothermal project in Hungary have now been made available through an EIA filing.
Details on the planned expansion of the geothermal power project in the town of Tura in Pest County, Hungary, have been made available through Environmental Impact Assessment (EIA) documents submitted by Turawell Kft.
In early 2025, it was announced that KS ORKA Hungary Kft, a subsidiary of Kaishan Corporation, had been awarded a geothermal exploration license for a 171 km² area in the Tura region. Incidentally, the license area includes the Turawell geothermal power plant, the only operational geothermal power plant in Hungary. KS Orka currently holds a majority stake in Turawell Kft following an acquisition back in 2016.
Development plan for the Tura-2 project
The Tura-1 geothermal power plant has an installed nominal capacity of 3.5 MWe and a net capacity of 2.7 MWe. Its construction began in 2017, and operations started in 2018. The power plant originally operated on one production and two reinjection wells, which was augmented in 2020 by another production well. To date, the Tura-1 power plant remains the only geothermal power plant operating in Hungary.
The Tura-2 geothermal power plant will be built in the immediate vicinity of the existing power plant. When the Tura-2 power plant is put into operation, the Tura-1 power plant will be shut down. The company aims to continue to maintain Tura-1 as an educational and scientific facility, thus there are no plans for its demolition.
Like Tura-1, the geothermal power plant will use binary power plant technology, specifically with N-butane as the secondary working fluid. Tura-2 will have an installed capacity of 10.5 MW. The existing V-1 (T = 127 °C, Depth = 1489 m) and V-1A (T = 125 °C, Depth = 1800 m) wells will be used for production, and reinjection is planned into the T-1 and Tu-4 wells. No new wells will be drilled. The planned start of operations of the Tura-2 geothermal power plant is Q3 2026.
