OilMakkahSaudi Arabia

RABIGH IWSPP is a 830 MW oil power station in Makkah, Saudi Arabia. It is operated by Rabigh Arabian Water and Electricity Company. Based on its capacity (estimated), it can supply roughly 623k homes (estimated). It ranks #56 of 156 Saudi Arabia power plants by installed capacity. Commissioned in 2016, it is around 10 years old — relatively modern. 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 830 MW, RABIGH IWSPP is well above the median oil plant in Saudi Arabia (365 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.

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

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 22.7°N — which shapes how much energy it can produce and how its output varies through the year.

This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.

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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
