Aluto-Langano is a 7.3 MW geothermal power plant in Oromiya, Ethiopia. Based on its capacity (estimated), it can supply roughly 14k homes (estimated). It ranks #15 of 15 Ethiopia power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 0.1% of Ethiopia's electricity; the national grid averages 23 gCO₂/kWh (100.0% low-carbon) (2025).

In context: how this plant compares
Geothermal plants tap underground heat to raise steam for a turbine; they provide steady, low-carbon baseload but are limited to geologically active regions.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
Local climate & thermal context
This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a subtropical highland climate (Köppen Cwb) — Northern Hemisphere, latitude 7.8°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 74% below 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: 22/100 — this site sits in the bottom 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.
