Hydro power plant in Wangdi Phodrang, Bhutan. Approximate location 27.4254, 89.9043.

HydroWangdi PhodrangBhutanrun-of-river

Basochhu Hydroelectric Power Plant Bhutan is a 64 MW hydro power plant in Wangdi Phodrang, Bhutan. It is operated by Druk Green Power CORP LTD (DGPC). Based on its capacity (estimated), it can supply roughly 64k homes (estimated). It ranks #3 of 5 Bhutan power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. 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 64 MW, Basochhu Hydroelectric Power Plant Bhutan is around the median hydro plant in Bhutan (64 MW). Technically it is described as run-of-river. 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.

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 44% 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: 32/100 — this site sits in the bottom 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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
