Gross electricity generation in Bosnia and Herzegovina’s power sector totalled 1,090 GWh in August. That was down from 1,122 GWh a year earlier, as lower thermal output outweighed gains in hydropower and renewables. Thermal plants supplied 62.1% of gross generation, hydropower 27.9%, and wind and solar combined 10%.
Net hydropower production rose 17.1% year on year to 287 GWh. The increase provided some support to the national electricity balance. Hydropower was the only one of the three generation categories to record a double-digit rise.
Thermal generation fell 13.8% to 598 GWh. By contrast, wind and solar output increased 6.9% to 109 GWh. Together, wind and solar accounted for 10% of gross electricity generation.
Imports, exports and fuel supply
Lower thermal generation increased the country’s reliance on cross-border electricity supply. Imports climbed 20.8% to 436 GWh, compared with 361 GWh in August 2025. Exports rose by just 0.7%, from 591 GWh to 595 GWh.
Coal output figures also indicated pressure on the thermal fleet. Lignite production declined 3.9% year on year to 498,000 tonnes. Brown-coal output dropped 29.7% to 306,000 tonnes.
Natural-gas imports fell 45.7% to 5.69 million cubic metres, from 10.48 million cubic metres a year earlier. The August figures show hydropower and new renewables offsetting part of the decline in coal generation. They were not sufficient to prevent higher import requirements when thermal availability weakened.
