Karratha is a 86 MW gas power plant in Western Australia, Australia. It is operated by ATCO Power. Based on reported annual generation of 79 GWh, it can supply roughly 22,542 homes. It ranks #172 of 512 Australia power plants by installed capacity. Its measured emissions of 88,624 t CO₂/yr (Climate TRACE) are equivalent to about 20,658 cars driven for a year. In context, gas supplies about 16.4% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot desert climate (Köppen BWh) — Southern Hemisphere, latitude 20.8°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 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.
A gas turbine here also runs ~9% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #68 largest gas power plant of 142 in Australia by capacity.
Australia has 142 gas power plants in this dataset, together about 21,303 MW of capacity.
