Nirmalapura is a 10 MW wind power plant in North Western, Sri Lanka. It is operated by Nirmalapura Wind Power. Based on its capacity (estimated), it can supply roughly 8,935 homes (estimated). It ranks #35 of 48 Sri Lanka power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 5.4% of Sri Lanka's electricity; the national grid averages 329 gCO₂/kWh (61.6% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 8.0°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
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.
