Assam Gas Based power station is a 291 MW gas power station in Assam, India. It is operated by North Eastern Electric Power Corp Ltd. Based on its capacity (estimated), it can supply roughly 328k homes (estimated). It ranks #647 of 2,225 India power plants by installed capacity. Commissioned in 1998, it is around 28 years old — long-established. Its modelled annual emissions are 244,620 t CO₂/yr (Climate TRACE), equivalent to about 57k cars driven for a year. In context, gas supplies about 2.3% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

In context: how this plant compares
At 291 MW, Assam Gas Based power station is well above the median gas plant in India (234.3 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 humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 27.3°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 96% 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: 15/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~6% 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.
