HydroTashigangBhutan

Rangjung Small Hydroelectric Power Plant Bhutan is a 2 MW hydro power plant in Tashigang, Bhutan. Based on its capacity (estimated), it can supply roughly 2,202 homes (estimated). It ranks #5 of 5 Bhutan power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 100.0% of Bhutan's electricity; the national grid averages 24 gCO₂/kWh (100.0% low-carbon) (2024).

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 27.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 37% above 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: 73/100 — this site sits in the top 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.
