HydroSikkimIndia

RANGIT-III is a 60 MW hydro power plant in Sikkim, India. Based on reported annual generation of 347 GWh, it can supply roughly 99,228 homes. It ranks #686 of 1,908 India power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 8.6% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a subtropical highland climate (Köppen Cwb) — Northern Hemisphere, latitude 27.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 82% 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: 20/100 — 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.
