HPP Višegrad generation falls in March 2026 as seasonal hydrology bites

Hydropower output at Bosnia and Herzegovina’s HPP Višegrad eased in March 2026, underscoring how quickly generation can swing with seasonal changes in water availability. The plant’s operator, Hidroelektrane na Drini, reported electricity production of 94.72 GWh for the month.

The figure marked a 34.2% decline versus February 2026, when output reached 143.98 GWh. Compared with March of the previous year, generation was also lower: the plant produced 120.21 GWh in March 2025.

Annual production shows growth, but early-2026 remains shaped by seasonality

Despite the softer monthly performance, HPP Višegrad generated more electricity over the full year of 2025 than in 2024. Total production came to 781.8 GWh in 2025, compared with 733 GWh in 2024—an increase that suggests overall hydropower conditions were supportive across the year.

Looking at the current year, cumulative generation since the start of 2026 has reached 400.4 GWh. The operator attributed this level to ongoing seasonal variability in hydrological conditions.

Plant profile: capacity, commissioning date and production record

Commissioned in 1989, HPP Višegrad is equipped with an installed capacity of 315 MW, configured as three units of 105 MW each. The plant’s average annual production is approximately 1,010 GWh.

Its highest annual output occurred in 2010, when it generated 1,283.05 GWh—its record level since coming into operation.

For investors and market participants tracking regional power supply, the March drop highlights the importance of timing when assessing hydropower performance: even when annual totals improve modestly year-on-year, monthly generation can still fall sharply as water conditions shift through the seasons.
