Bayswater is a 2,665 MW coal power station in New South Wales, Australia. It is operated by Macquarie Generation. Based on reported annual generation of 15,546 GWh, it can supply roughly 4.4 million homes. It ranks #1 of 536 Australia power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. Its modelled annual emissions are 16,222,200 t CO₂/yr (Climate TRACE), equivalent to about 3.8 million 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 2,665 MW, Bayswater is well above 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 humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 32.4°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 69% 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: 24/100 — 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 a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness 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.
