GACL-NALCO Dahej Caustic captive power station is a 130 MW coal power station in Gujarat, India. It is operated by GACL-NALCO Alkalies and Chemicals Pvt Ltd. Based on its capacity (estimated), it can supply roughly 163k homes (estimated). It ranks #789 of 2,225 India power plants by installed capacity. Its modelled annual emissions are 739,300 t CO₂/yr (Climate TRACE), equivalent to about 172k cars driven for a year. In context, coal supplies about 70.8% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

In context: how this plant compares
At 130 MW, GACL-NALCO Dahej Caustic captive power station is below the median coal plant in India (1,000 MW). 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.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a hot semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 21.7°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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
