METTUR is a 840 MW coal power station in Tamil Nadu, India. It is operated by Tamil Nadu Power Distribution Corp Ltd. Based on reported annual generation of 5,314 GWh, it can supply roughly 1,518,371 homes. It ranks #172 of 1,908 India power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. Its measured emissions of 7,725,300 t CO₂/yr (Climate TRACE) are equivalent to about 1,800,769 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).

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 11.8°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 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.

The #145 largest coal power plant of 395 in India by capacity.
India has 395 coal power plants in this dataset, together about 300,917 MW of capacity.
