Ajman Coal power station — United Arab Emirates

Ajman Coal power station is a 1,000 MW coal power station in Emirate of Ajman, United Arab Emirates. It is operated by MMC Corporation Bhd [100%]. Based on its capacity (estimated), it can supply roughly 1.3 million homes (estimated). It ranks #24 of 60 United Arab Emirates power plants by installed capacity. In context, coal supplies about 0.0% of United Arab Emirates's electricity; the national grid averages 468 gCO₂/kWh (31.7% low-carbon) (2024).

Data provenance

Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

capacity: GEM GCPT; fuel: GEM GCPT

In context: how this plant compares

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 hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 25.4°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.
