Worsley is a 120 MW coal power station in Western Australia, Australia. It is operated by BHP. Based on its capacity (estimated), it can supply roughly 150k homes (estimated). It ranks #159 of 536 Australia power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. Its modelled annual emissions are 923,780 t CO₂/yr (Climate TRACE), equivalent to about 215k cars driven for a year. In context, coal supplies about 42.7% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

In context: how this plant compares
At 120 MW, Worsley is below the median coal plant in Australia (700 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Southern Hemisphere, latitude 33.2°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 52% 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: 28/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt 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.
