HydroLao CaiVietnam

Ngoi Phat is a 72 MW hydro power plant in Lao Cai, Vietnam. It is operated by Northern Electricity development and investment JSC. No.2. Based on reported annual generation of 314 GWh, it can supply roughly 89,714 homes. It ranks #86 of 236 Vietnam power plants by installed capacity. Commissioned in 2014, it is around 12 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).

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 22.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 59% 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: 26/100 — 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.
