Tanajib Cogeneration and Desalination power plant — Saudi Arabia

Tanajib Cogeneration and Desalination power plant is a 940 MW gas power station in Eastern, Saudi Arabia. It is operated by Marubeni Corp [30%]; Saudi Arabian Oil Co [40%]; Abu Dhabi National Energy Compa. Based on its capacity (estimated), it can supply roughly 1.1 million homes (estimated). It ranks #52 of 156 Saudi Arabia power plants by installed capacity. Commissioned in 2025, it is around 1 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 940 MW, Tanajib Cogeneration and Desalination 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 Saudi Advanced Turbines: 7F.05. 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.
