High Dam is a 2,100 MW hydro power station in Aswan, Egypt. It is operated by Egyptian Electricity Holding Company (EEHC). Based on reported annual generation of 9,304 GWh, it can supply roughly 2.7 million homes. It ranks #13 of 89 Egypt power plants by installed capacity. Commissioned in 1967, it is around 59 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 6.1% of Egypt's electricity; the national grid averages 563 gCO₂/kWh (13.0% low-carbon) (2025).

In context: how this plant compares
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 hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 24.0°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 97% 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: 15/100 — 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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
