August 2026 generation mix and year-on-year increase
Croatia’s electricity production rose 13% year on year to 1,262 GWh in August 2026, according to figures from the Croatian Bureau of Statistics. The data show output increasing from 1,117 GWh in August 2025. Hydropower, thermal generation and a growing renewable contribution supported the higher total.
Hydropower remained the largest source at 412 GWh, equivalent to 32.6% of total electricity output. Thermal power plants generated 381 GWh, or 30.2%, while solar installations produced 220 GWh, accounting for 17.4%. Wind farms supplied an additional 180 GWh, representing 14.3%.
Together, wind and solar contributed 400 GWh, reflecting a larger role for these sources in Croatia’s supply structure. Despite the higher domestic generation, the country’s electricity import volumes did not decline.
Electricity trade flows and net import position
Croatia imported 1,198 GWh during August, up 8.8% from the same month a year earlier. Electricity exports fell by 4% to 546 GWh. The net electricity import position widened to approximately 652 GWh, compared with 532 GWh in August 2025.
The data indicate that increased domestic output had not removed Croatia’s reliance on regional electricity markets. This exposure remains relevant during periods when domestic hydro and renewable generation are insufficient for consumption needs.
Natural gas and crude oil production alongside external supply
Croatia’s hydrocarbon sector also showed dependence on external supply, alongside the power market balance. Domestic natural gas production declined by 4.9% to 58 million cubic metres. Gas imports rose by 163% to 276 million cubic metres.
Crude oil production increased by 2.6% to 39,000 tonnes. Petroleum product output rose to 333,000 tonnes, from 316,000 tonnes a year earlier.
The combination of higher electricity generation, increased gas imports and a wider power import balance points to continued reliance on regional energy trade as renewable investment expands domestically.
