Andakíl is a 8 MW hydro power plant in West, Iceland. It is operated by Orkuveita Reykjavíkur. Based on its capacity (estimated), it can supply roughly 8.0k homes (estimated). It ranks #19 of 20 Iceland power plants by installed capacity. Commissioned in 1947, it is around 79 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 70.7% of Iceland's electricity; the national grid averages 28 gCO₂/kWh (100.0% low-carbon) (2024).

In context: how this plant compares
At 8 MW, Andakíl is below the median hydro plant in Iceland (95 MW). 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 polar tundra climate (Köppen ET) — Northern Hemisphere, latitude 64.5°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 126% 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: 97/100 — 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 marine corrosion 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.
