ASIR — Saudi Arabia

ASIR is a 695.8 MW oil power station in Mintaqat `Asir, Saudi Arabia. It is operated by Saudi Electricity Company (SEC). Based on its capacity (estimated), it can supply roughly 522k homes (estimated). It ranks #64 of 156 Saudi Arabia power plants by installed capacity. Commissioned in 2006, it is around 20 years old — relatively modern. Its modelled annual emissions are 1,919,000 t CO₂/yr (Climate TRACE), equivalent to about 447k cars driven for a year. In context, oil supplies about 34.5% of Saudi Arabia's electricity; the national grid averages 692 gCO₂/kWh (2.2% low-carbon) (2024).

In context: how this plant compares

At 695.8 MW, ASIR is well above the median oil plant in Saudi Arabia (364.6 MW). Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a cold desert climate (Köppen BWk) — Northern Hemisphere, latitude 18.2°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 91% 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: 17/100 — 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.
