Mount Millar Wind Farm is a 70 MW wind power plant in South Australia, Australia. It is operated by Meridian Energy Australia. Based on reported annual generation of 193 GWh, it can supply roughly 55,171 homes. It ranks #200 of 512 Australia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 13.7% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 33.6°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 67% 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: 24/100 — 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.

The #31 largest wind power plant of 65 in Australia by capacity.
Australia has 65 wind power plants in this dataset, together about 5,739 MW of capacity.
