Oaky Creek is a 20 MW gas power plant in Queensland, Australia. It is operated by EnvironGen (Oaky) Pty Ltd. Based on reported annual generation of 130 GWh, it can supply roughly 37k homes. It ranks #345 of 536 Australia power plants by installed capacity. Its modelled annual emissions are 57,575 t CO₂/yr (Climate TRACE), equivalent to about 13k 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).

At 20 MW, Oaky Creek is below the median gas plant in Australia (106 MW). 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.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot semi-arid steppe climate (Köppen BSh) — Southern Hemisphere, latitude 23.0°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 96% 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: 15/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~5% 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
