Croatia’s electricity system remained heavily dependent on cross-border supply in June even as renewables provided a substantial share of domestic generation. Net electricity production reached 881 GWh, down 2.7 per cent from 905 GWh in June 2025.
Hydropower remained the largest domestic source, accounting for about 39 per cent of output. Wind farms supplied 152 GWh, equivalent to 17.3 per cent, while solar plants generated 195 GWh, or 22.1 per cent of national production. Thermal plants contributed 119 GWh, representing 13.5 per cent.
The wider balance shows that domestic generation was still insufficient to cover the country’s electricity requirements. Croatia imported 1,262 GWh during the month, only marginally below the 1,267 GWh imported a year earlier. Exports fell more visibly, declining 5.4 per cent to 547 GWh from 578 GWh.
The figures underline the increasingly mixed character of the Croatian system. Solar and wind are becoming material contributors to production, but the country continues to rely substantially on regional trading to balance demand. The scale of gross imports relative to domestic generation means Croatia remains exposed to SEE and Central European wholesale prices during periods of weak hydro or renewable output.
Domestic natural gas production also weakened. Croatia produced 51mn cubic metres of gas, down 16.4 per cent year on year, while imports rose 41.6 per cent to 269mn cubic metres. Crude oil production declined 2.6 per cent to 37,000 tonnes, although petroleum-product output increased to 334,000 tonnes, compared with 299,000 tonnes in June 2025.
