Croatia’s net electricity production in June reached 881 GWh, down 2.7% from 905 GWh recorded in June 2025. Cross-border supply remained a significant component of the country’s electricity balance during the month. Renewables provided a substantial share of domestic generation alongside other sources.
Domestic generation mix in June
Hydropower was the largest domestic source, contributing about 39% of output. Wind farms generated 152 GWh, equal to 17.3% of national production. Solar plants produced 195 GWh, representing 22.1%, while thermal plants contributed 119 GWh or 13.5%.
Import and export flows for the month
The overall balance indicates that domestic generation did not fully meet Croatia’s electricity requirements. Croatia imported 1,262 GWh in June, marginally below the 1,267 GWh imported a year earlier. Exports declined by 5.4%, falling to 547 GWh from 578 GWh.
The scale of gross imports relative to domestic output meant Croatia continued to rely on regional trading to balance demand. During periods of weak hydro or renewable output, the import volume links Croatia’s exposure to wholesale price dynamics in Southeast Europe and Central Europe.
Natural gas and crude oil production trends
Croatia’s domestic natural gas production weakened in June, reaching 51mn cubic metres, down 16.4% year on year. Gas imports rose by 41.6% to 269mn cubic metres. Crude oil output declined by 2.6% to 37,000 tonnes.
Pertroleum-product production increased to 334,000 tonnes, compared with 299,000 tonnes in June 2025.
