Kwinana is a 21 MW gas power plant in Western Australia, Australia. It is operated by Verve Energy. Based on its capacity (estimated), it can supply roughly 24k homes (estimated). It ranks #337 of 536 Australia power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. In context, gas supplies about 16.4% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 200 MW for Kwinana power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares
At 21 MW, Kwinana is below the median gas plant in Australia (106 MW). Technically it is described as OCGT. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

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 hot-summer Mediterranean climate (Köppen Csa) — Southern Hemisphere, latitude 32.2°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 74% 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: 22/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~2% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
