Ta Thang is a 60 MW hydro power plant in Lao Cai, Vietnam. It is operated by Lao Cai Vietracimex Electricity JSC.. Based on reported annual generation of 242 GWh, it can supply roughly 69k homes. It ranks #157 of 298 Vietnam power plants by installed capacity. Commissioned in 2013, it is around 13 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).

At 60 MW, Ta Thang is well above the median hydro plant in Vietnam (20 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.

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 22.3°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 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.
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.
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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
The #55 largest hydro power plant of 174 in Vietnam by capacity.
Vietnam has 174 hydro power plants in this dataset, together about 17,313 MW of capacity.
