Siddhirganj (Dutch Bangla) — Bangladesh

Siddhirganj (Dutch Bangla) is a 520 MW gas power station in Rajshahi, Bangladesh. It is operated by Dutch Bangala. Based on its capacity (estimated), it can supply roughly 586k homes (estimated). It ranks #54 of 129 Bangladesh power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. In context, gas supplies about 64.3% of Bangladesh's electricity; the national grid averages 696 gCO₂/kWh (2.1% low-carbon) (2025).

In context: how this plant compares

At 520 MW, Siddhirganj (Dutch Bangla) is around the median gas plant in Bangladesh (553 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

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 tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 24.4°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 99% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~7% 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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
