HydroXekongLaos

Xeset 1 is a 121 MW hydro power station in Xekong, Laos. Based on its capacity (estimated), it can supply roughly 121,138 homes (estimated). It ranks #8 of 20 Laos power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 76.5% of Laos's electricity; the national grid averages 232 gCO₂/kWh (76.7% low-carbon) (2024).

Local climate & thermal context

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 15.5°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.
