UNCHAHAR is a 1,550 MW coal power station in Uttar Pradesh, India. Based on reported annual generation of 6,552 GWh, it can supply roughly 1,872,000 homes. It ranks #57 of 1,908 India power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. In context, coal supplies about 70.8% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from reported annual generation × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 25.9°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.
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 #52 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.
