Sultan Aziz power station is a 2,164 MW coal power station in Perak, Malaysia. It is operated by Kapar Energy Ventures Sdn Bhd. Based on its capacity (estimated), it can supply roughly 2.7 million homes (estimated). It ranks #7 of 82 Malaysia power plants by installed capacity. Commissioned in 1996, it is around 30 years old — long-established. In context, coal supplies about 44.6% of Malaysia's electricity; the national grid averages 602 gCO₂/kWh (20.7% low-carbon) (2025).

In context: how this plant compares
At 2,164 MW, Sultan Aziz power station is well above the median coal plant in Malaysia (1,400 MW). Technically it is described as Steam; subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical rainforest climate (Köppen Af) — Northern Hemisphere, latitude 3.1°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
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
This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt 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.
