Rangjung Small Hydroelectric Power Plant Bhutan is a 2.2 MW hydro power plant in Tashigang, Bhutan. Based on its capacity (estimated), it can supply roughly 2.2k 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).

In context: how this plant compares
At 2.2 MW, Rangjung Small Hydroelectric Power Plant Bhutan is below the median hydro plant in Bhutan (64 MW). Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Capacity vs largest hydro plants in Bhutan
Installed capacity (MW), WRI Global Power Plant Database (CC BY 4.0).
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.
Monthly mean temperature
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.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
