Duyen Hai 1 is a 1,244 MW coal power station in Tra Vinh, Vietnam. It is operated by Vietnam Electricity (EVN). Based on its capacity (estimated), it can supply roughly 1.6 million homes (estimated). It ranks #51 of 298 Vietnam power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. In context, coal supplies about 48.1% of Vietnam's electricity; the national grid averages 461 gCO₂/kWh (45.4% low-carbon) (2025).

In context: how this plant compares
At 1,244 MW, Duyen Hai 1 is well above the median coal plant in Vietnam (650 MW). Technically it is described as supercritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 9.6°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
