Dray H'Linh 2 is a 16 MW hydro power plant in Dak Nong, Vietnam. It is operated by Dien Luc 3 Hydro Power JSC.. Based on reported annual generation of 80 GWh, it can supply roughly 23k homes. It ranks #221 of 298 Vietnam power plants by installed capacity. Commissioned in 2007, it is around 19 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 33.0% of Vietnam's electricity; the national grid averages 461 gCO₂/kWh (45.4% low-carbon) (2025).

In context: how this plant compares
At 16 MW, Dray H'Linh 2 is below the median hydro plant in Vietnam (20 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.

Local climate & thermal context
This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 12.7°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
How it compares & nearby plants
