The construction of Croatia’s largest solar power plant has entered its final stage, with the installation of roughly 160,000 photovoltaic panels completed at the beginning of January. Located next to HEP’s existing Korlat wind farm, the project represents a major milestone in the country’s renewable energy expansion.
With an installed capacity of 99 MW, the Korlat solar plant will operate alongside the adjacent 58 MW wind facility, forming a hybrid renewable energy park capable of producing around 165 GWh of electricity annually—enough to supply roughly 100,000 households. The solar installation, built by Chinese company Norinco, is expected to become operational later this year, with a total investment of about 70 million euros.
Dalmatia has emerged as a key region for solar investment in Croatia. Combined with other renewable sources, these projects have already pushed the share of non-fossil electricity beyond two-thirds of national production.
Another recent addition came in November 2025, when the Dugopolje solar power plant began commercial operation. Located in central Dalmatia, the facility has an installed capacity of 13.5 MW, featuring 23,452 panels arranged in 26 strings. Expected to generate 17.2 GWh annually, the plant will supply electricity to around 6,000 households. Designed and built by Koncar, construction began in January 2024, with a total investment of approximately 11 million euros.
HEP currently operates 11 non-integrated solar power plants connected to the national grid, while another seven are under construction. In addition to Dugopolje, standalone plants at Crnkovci and Jambrek began regular operation in 2025. Projects such as Radosavci, Lipik, and Cakovec are approaching critical milestones, with some preparing for grid connection.
Solar development is also extending to Croatia’s islands. Construction is underway on a 1 MW plant on Unije, following a previous project on Vis. The Unije facility is expected to cover a large portion of the island’s electricity demand, with potential battery storage and grid-independent operation under consideration. Additional island projects include the 8 MW Bogomolje plant on Hvar and a 6.5 MW facility near Orlec on Cres, with another Cres project near Ustrine in preparation.
On the mainland, HEP has six advanced solar projects, with the 45 MW Sukosan plant standing out in terms of size. Rooftop solar generation also continues to expand, with over 65 integrated systems already installed on company-owned buildings and preparations underway for 90 additional rooftop plants, further strengthening Croatia’s distributed renewable energy capacity.
