GasTamil NaduIndia

KARUPPUR GT is a 120 MW gas power station in Tamil Nadu, India. Based on reported annual generation of 633 GWh, it can supply roughly 180,971 homes. It ranks #495 of 1,908 India power plants by installed capacity. Commissioned in 2005, it is around 21 years old — relatively modern. In context, gas supplies about 2.3% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

~253,360 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

59,058passenger cars driven for a year
33,041homes' yearly energy use
4,222,667tree seedlings grown 10 years to absorb it

Estimated, not measured: from reported annual generation × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 11.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 100% 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.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

A gas turbine here also runs ~9% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
