Sangachal ES — Azerbaijan

Sangachal ES is a 299 MW gas power station in Baki, Azerbaijan. It is operated by AzerEnerji. Based on its capacity (estimated), it can supply roughly 337k homes (estimated). It ranks #11 of 22 Azerbaijan power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. In context, gas supplies about 87.6% of Azerbaijan's electricity; the national grid averages 632 gCO₂/kWh (12.1% low-carbon) (2025).

In context: how this plant compares

At 299 MW, Sangachal ES is well above the median gas plant in Azerbaijan (107 MW). Technically it is described as Engine. 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 40.2°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 21% 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: 42/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~0% 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 a corrosive environment (estimated ISO 9223 class C4 — High), with dust abrasion 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.
