Millmerran is a 856 MW coal power station in Queensland, Australia. It is operated by Intergen. Based on reported annual generation of 7,061 GWh, it can supply roughly 2,017,542 homes. It ranks #15 of 512 Australia power plants by installed capacity. Its measured emissions of 5,440,400 t CO₂/yr (Climate TRACE) are equivalent to about 1,268,159 cars driven for a year. In context, coal supplies about 42.7% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 28.0°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 #13 largest coal power plant of 31 in Australia by capacity.
Australia has 31 coal power plants in this dataset, together about 26,933 MW of capacity.
