Bosnia and Herzegovina generated 14.4 TWh of electricity in 2025, matching the previous year’s total despite noticeably weaker performance from both coal-fired and hydropower plants. The stability of overall output was achieved only because new wind and solar capacity stepped in to fill the gap left by traditional sources.
According to data from the country’s transmission operator and statistical authorities, the decline in thermal and hydro generation was largely offset by privately financed renewable projects. Energy analyst Edhem Bičakčić stressed that these investments have become a key pillar of BiH’s power system, reshaping the structure of electricity supply.
Physical volumes of cross-border electricity trade declined during the year. Exports fell to 7.8 TWh, while imports dropped to 5.4 TWh, with both figures around 9% lower year-on-year. In financial terms, however, trends diverged sharply. Export revenues climbed to about €445 million, roughly 30% higher than in 2024, while the cost of imports surged to around €322 million, more than double the previous year’s level. Although net exports remained stable at 2.4 TWh, their financial contribution weakened, with net export income slipping to about €123 million, nearly one-third lower than a year earlier.
A closer look at generation by source highlights the changing energy mix. Coal-fired plants produced 7.8 TWh, around 7% less than in 2024, reflecting ongoing coal shortages and reduced availability of thermal units. Hydropower output fell by 8% to 4.3 TWh due to unfavorable hydrological conditions that persisted for much of the year.
In contrast, wind and solar plants connected to the transmission grid delivered 1.2 TWh, effectively doubling their output as new projects came online. Smaller renewable facilities linked to the distribution network — including small hydropower, industrial plants, solar, wind and biogas — generated a combined 1.1 TWh, an increase of almost 50% year-on-year.
Bičakčić expects the rapid build-out of solar capacity to continue reshaping Bosnia and Herzegovina’s power sector, with further growth anticipated through 2026 as additional renewable projects are commissioned.
