In the first quarter of 2025, Croatia’s electricity consumption rose by 5.5% to 4,893 GWh, driven by colder weather and stronger economic activity, according to the Renewable Energy Association of Croatia (OIEH). This surge turned Croatia into a net importer of electricity, with imports totaling 326 GWh, a sharp reversal from the 125 GWh exported in the same period last year.
Hydropower output dropped by 17.8% due to poor hydrological conditions, though it remained the largest energy source, providing 33.6% of total supply. Renewable energy production grew by 17.6% to 1,265 GWh, capturing a 25.7% share and surpassing fossil-fuel plants for the first time. Fossil-fuel thermal plants contributed 18.5%, while Croatia’s share from the Krško nuclear power plant accounted for 15.4%.
Despite renewable energy gains, reduced hydropower generation and rising demand led to a negative energy trade balance for the first time in a year.
