Southern Cross power station is a 244 MW gas power station in Western Australia, Australia. It is operated by TransAlta Corp. Based on its capacity (estimated), it can supply roughly 274,813 homes (estimated). It ranks #66 of 512 Australia power plants by installed capacity. Its measured emissions of 352,040 t CO₂/yr (Climate TRACE) are equivalent to about 82,061 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 cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 31.2°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 71% 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: 23/100 — 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 ~2% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #28 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.
