Green Duba ISCC power plant — Saudi Arabia

Green Duba ISCC power plant is a 550 MW gas power station in Tabuk, Saudi Arabia. It is operated by Saudi Electricity Co [100%]. Based on its capacity (estimated), it can supply roughly 619k homes (estimated). It ranks #68 of 156 Saudi Arabia power plants by installed capacity. Commissioned in 2022, it is around 4 years old — recently built. 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 550 MW, Green Duba ISCC power plant is well above the median gas plant in Saudi Arabia (496.7 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); GE Power: 7F.05, GE Power: 7F.03. 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.

Climate zone & how it works

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 27.8°N — which shapes how much energy it can produce and how its output varies through the year.

Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

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.
