Warragamba is a 50 MW hydro power plant in New South Wales, Australia. It is operated by Eraring Energy. Based on its capacity (estimated), it can supply roughly 50,057 homes (estimated). It ranks #239 of 512 Australia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 4.3% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 33.9°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 65% 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: 25/100 — 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.
