Rocky Point Sugar Sugar Mill is a 30 MW biomass power plant in Queensland, Australia. It is operated by Stanwell Corporation Ltd. Based on its capacity (estimated), it can supply roughly 41,297 homes (estimated). It ranks #284 of 512 Australia power plants by installed capacity. In context, biomass supplies about 1.1% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 27.7°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 89% 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: 17/100 — 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.
