The tender will be for the drilling of two geothermal wells – a vertical production well (GTZ-1) to a depth of 4000 meters with the possibility of additional 100 meters depth, and a deviated reinjection well (GTZ-2) to a vertical depth of 3400 meters and measured depth of 3992 meters.
The Ziar geothermal power project has a total expected generation capacity of 20 MWe. Deep geothermal water with an expected temperature of 130 to 140 degrees °C will be used to produce electricity using modern technological equipment. Residual heat can then be used for domestic heating, industrial heating, agriculture, and recreational purposes.
A pre-tender request for information had been published by PW Energy for drilling at the Ziar nad Hronom project in early 2022.
In mid-2022, Stredoslovenska energetika Holding (SSE Holding) group acquired a stake in PW Geoenergy, a subsidiary that was established primarily for the implementation of a geothermal power plant in the district of Ziar nad Hronom.
