Hydro power plant in Chittagong, Bangladesh. Approximate location 22.495, 92.216.
HydroChittagongBangladeshconventional storage
Kaptai Hydro:Unit-1 2 3 4 5 is a 230 MW hydro power station in Chittagong, Bangladesh. It is operated by Bangladesh Power Development Board. Based on its capacity (estimated), it can supply roughly 230k homes (estimated). It ranks #63 of 129 Bangladesh power plants by installed capacity. Commissioned in 1962, it is around 64 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 0.6% of Bangladesh's electricity; the national grid averages 696 gCO₂/kWh (2.1% low-carbon) (2025).

In context: how this plant compares
Technically it is described as conventional storage. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
Owner
Operated by Bangladesh Power Development Board.
Local climate & thermal context
This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 22.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
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 humidity / wetness 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.
