Az Zawiyah is a 1,440 MW gas power station in Az Zawiyah, Libya. It is operated by General Electricity Company of Libya. Based on its capacity (estimated), it can supply roughly 1.6 million homes (estimated). It ranks #4 of 27 Libya power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. In context, gas supplies about 74.5% of Libya's electricity; the national grid averages 827 gCO₂/kWh (0.0% low-carbon) (2024).

In context: how this plant compares
At 1,440 MW, Az Zawiyah is well above the median gas plant in Libya (1,000 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); ABB PGL: GT13E2, Fuji Electric Co: ST, ABB PGL: GT13E2. 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

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 semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 32.8°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 76% 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: 22/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~3% 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.
