After the completion of the geological survey and the administrative preparation of the assignment, in March 2021, the company PW Energy has introduced the project for the utilization of geothermal energy for power production in the Žiar nad Hronom region. In 2022, a partnership between PW Energy and SSE Holding was agreed and the project is now being conducted by a joint company PW geoenergy.
Electricity generation will take place in a facility based on the ORC (Organic Rankine Cycle), with an installed electrical capacity of 6.3 to 6.5 MWe.
The power plant will utilize the energy using six wells (three production and three re-injection) in a closed loop with re-injection of the thermally exploited geothermal water, thanks to which the water will be reused in the production loop. Planned is the implementation of a total of three doublets (designation of production + re-injection well).
The development of the geothermal center is planned in the cadaster of Lovča. The annual production of electricity in the first phase will be more than 43-thousand megawatt hours. The total potential capacity of the resource is estimated to be 3-times this size. Residual heat from the power production can be further utilized, in example for district heating supply, in agriculture, industry or for recreational purposes.
