Gas power plant in Eastern Province, Saudi Arabia. Approximate location 27.5843, 48.9676.
GasEastern ProvinceSaudi ArabiaCO₂ modelled
Manifa cogeneration power plant is a 420 MW gas power station in Eastern Province, Saudi Arabia. It is operated by Saudi Arabian Oil Co. Based on its capacity (estimated), it can supply roughly 473k homes (estimated). It ranks #78 of 156 Saudi Arabia power plants by installed capacity. Its modelled annual emissions are 706,110 t CO₂/yr (Climate TRACE), equivalent to about 165k cars driven for a year. In context, gas supplies about 63.3% of Saudi Arabia's electricity; the national grid averages 692 gCO₂/kWh (2.2% low-carbon) (2024).

In context: how this plant compares
At 420 MW, Manifa cogeneration power plant is below the median gas plant in Saudi Arabia (496.7 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Local climate & thermal context
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 27.6°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.
A gas turbine here also runs ~8% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
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.
