Banshkhali power station (S Alam) is a 1,320 MW coal power station in Chattogram, Bangladesh. It is operated by SEPCOIII Electric Power Construction Co Ltd [20%]; S. Alam Cold Rolled Steels Lt. Based on its capacity (estimated), it can supply roughly 1.7 million homes (estimated). It ranks #20 of 129 Bangladesh power plants by installed capacity. Commissioned in 2023, it is around 3 years old — recently built. In context, coal supplies about 21.5% of Bangladesh's electricity; the national grid averages 696 gCO₂/kWh (2.1% low-carbon) (2025).

At 1,320 MW, Banshkhali power station (S Alam) is around the median coal plant in Bangladesh (1,320 MW). Technically it is described as supercritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 22.0°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).
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 corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness 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.
The #8 largest coal power plant of 29 in Bangladesh by capacity.
Bangladesh has 29 coal power plants in this dataset, together about 38,390 MW of capacity.
