Croatia's Hydrocarbon Agency (CHA) said it is inviting bids from potential investors interested in the exploration of geothermal water for energy purposes at four blocks in the Drava valley, in the country's northeast.
The four blocks - Ernestinovo, Lunjkovec-Kutnjak, Legrad-1 and Merhatovec, offered to investors have a total area of 207 square kilometres, the government agency said in a statement on Wednesday.
The water temperature at the locations exceeds 100 degrees Celsius, which is the minimum required for electricity generation. The combined potential of the deposits is some 50 MW of electricity.
"The potential of exploration areas has been identified in earlier wells drilled for oil and gas exploration and production, which now greatly reduces the risk and costs to future investors," CHA said.
"In addition to electricity, geothermal energy has great potential in district heating, where future investors, in cooperation with the local community, have the opportunity to cascade production - from electricity, district heating to agriculture where geothermal water is used to heat greenhouses," it pointed out.
