GasWestern AustraliaAustralia

Merredin is a 82 MW gas power plant in Western Australia, Australia. Based on reported annual generation of 0 GWh, it can supply roughly 114 homes. It ranks #178 of 512 Australia power plants by installed capacity. In context, gas supplies about 16.4% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

~160 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

37passenger cars driven for a year
21homes' yearly energy use
2,667tree seedlings grown 10 years to absorb it

Estimated, not measured: from reported annual generation × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

Local climate & thermal context

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 31.5°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 64% 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.

A gas turbine here also runs ~2% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
