HydroMaputoMozambique

Corumana is a 166 MW hydro power station in Maputo, Mozambique. Based on its capacity (estimated), it can supply roughly 166,189 homes (estimated). It ranks #2 of 3 Mozambique power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 82.4% of Mozambique's electricity; the national grid averages 129 gCO₂/kWh (83.4% 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 hot semi-arid steppe climate (Köppen BSh) — Southern Hemisphere, latitude 25.2°S — 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.
