The opening of a new, the third in a row, geothermal well is planned in Bjelovar, with a heating capacity of over 4 MW that would heat the future pools in Bjelovar’s Thermal Spa as well as the future business zone, as reported by Jutarnji list.

After the largest geothermal power plant in this part of Europe with a capacity of 15MW and the already drilled second well which confirmed the existence of hot water sufficient for heating the pools of the Bjelovar Thermal Spa,  the main project of which is already completed, a third well is planned – in Veliko Korenovo.

“The planned depth of the well is about 1500 meters and it is assessed that the temperature of the water at that point should be from 50 to 70 degrees. At this location, there is potential for a heating plant the capacity of which should be higher than four megawatts. It would also heat the spa which is currently waiting for the announcement of the competition for financing within the framework of the National Plan of Recovery and Resistance, the adjoining working facilities besides the spa as well as the future business zone Veliko Korenovo which will be one of the largest in continental Croatia covering a space of 80 hectares gifted to the City by the state”, Dario Hrebak, je mayor of Bjelovar pointed out and accentuated that even now Bjelovar meets almost half of the needs for electric power from alternative or renewable sources and can therefore be called ‘the small battery of Croatia’.

He also announced that by 29 November the City would register the project of preparations for the third well through the financial mechanism EGP (Kingdom of Norway, Island, Lichtenstein). The costs of the documentation amount to about 2 million HRK and it is possible to withdraw as much as 85 percent of that amount. Through this mechanism, a new competition is planned to which cities could also apply and withdraw up to 1.3 million EUR each for the construction of the well.

The head of the research activities in Veliko Korenovo,  Mladen Škrlec, pointed out that given the lengthy process of obtaining permits and of preparing the main project, the drilling is anticipated in early 2023. “Through the analyses of existing seismic and geophysical data in the field, we located this well and assessed its volume and temperature capacities. The drawing up of the concept design follows and then the elaboration of the environmental protection study and at the end the main project. In parallel, we are working on the location permit for this micro-location and according to the current assessment it should be done by the end of 2022”, Škrlec concluded and added that the construction of the well itself takes about three months and could be operational by the end of 2023.
