Besat is a 249 MW oil power station in Tehran, Iran. It is operated by Besat Power Generation Management Co [100%]. Based on its capacity (estimated), it can supply roughly 187k homes (estimated). It ranks #120 of 177 Iran power plants by installed capacity. Commissioned in 1968, it is around 58 years old — an older, legacy facility. In context, oil supplies about 4.6% of Iran's electricity; the national grid averages 660 gCO₂/kWh (5.7% low-carbon) (2025).

At 249 MW, Besat is below the median oil plant in Iran (640 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Mapna Group: MGT-75. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 35.6°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 23% 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: 41/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with thermal cycling the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
