GasTamil NaduIndiaCO₂ reported

Arkay Energy Rameswarm power station is a 255 MW gas power station in Tamil Nadu, India. It is operated by Arkay Energy Rameswarm Ltd. Based on its capacity (estimated), it can supply roughly 287,202 homes (estimated). It ranks #375 of 1,908 India power plants by installed capacity. Its measured emissions of 383,950 t CO₂/yr (Climate TRACE) are equivalent to about 89,499 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).

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 9.3°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 ~10% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
