The City of Dugo Selo had previously commissioned a study to assess the city’s geothermal potential (Full study available here). Several geophysical surveys have already been done at the site, and subsurface information is available from oil wells. All these information will be provided in the bidding documents for those who wish to participate in the tender.
Croatia remains very productive in its bid to grow its geothermal capacity, with several drilling operations (or related activities) taking place in geothermal sites simultaneously – in Velika Gorica, Durdevac, and Osijek.
