GasBa Ria-Vung TauVietnam

Phu My 21 is a 896 MW gas power station in Ba Ria-Vung Tau, Vietnam. It is operated by Vietnam Electricity (EVN). Based on its capacity (estimated), it can supply roughly 1,009,152 homes (estimated). It ranks #13 of 236 Vietnam power plants by installed capacity. In context, gas supplies about 6.2% of Vietnam's electricity; the national grid averages 461 gCO₂/kWh (45.4% low-carbon) (2025).

~1,412,813 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

329,327passenger cars driven for a year
184,248homes' yearly energy use
23,546,880tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 45% load factor × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 10.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 100% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

A gas turbine here also runs ~8% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
