Jajce I Hidroelektrana Bosnia and Herzegovina

Jajce I Hidroelektrana Bosnia and Herzegovina is a 48 MW hydro power plant in Federation of Bosnia and Herzegovina, Bosnia and Herzegovina. It is operated by Elektroprivreda HZHB Mostar dd. Based on its capacity (estimated), it can supply roughly 48k homes (estimated). It ranks #31 of 34 Bosnia and Herzegovina power plants by installed capacity. Commissioned in 1957, it is around 69 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 36.6% of Bosnia and Herzegovina's electricity; the national grid averages 571 gCO₂/kWh (43.6% low-carbon) (2025).

In context: how this plant compares

At 48 MW, Jajce I Hidroelektrana Bosnia and Herzegovina is below the median hydro plant in Bosnia and Herzegovina (114 MW). Technically it is described as conventional storage. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 44.4°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 61% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 84/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
