Nchalo Mill is a 10 MW biomass power plant in Southern Region, Malawi. Based on its capacity (estimated), it can supply roughly 13,765 homes (estimated). It ranks #5 of 5 Malawi power plants by installed capacity. In context, biomass supplies about 2.7% of Malawi's electricity; the national grid averages 55 gCO₂/kWh (95.6% low-carbon) (2024).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Southern Hemisphere, latitude 15.8°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 94% 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: 16/100 — 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.
