Collgar Wind Farm is a 222 MW wind power station in Western Australia, Australia. It is operated by UBS IIT/ REST. Based on reported annual generation of 716 GWh, it can supply roughly 204k homes. It ranks #95 of 536 Australia power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 13.7% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

At 222 MW, Collgar Wind Farm is well above the median wind plant in Australia (66 MW). Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 31.6°S — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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.
The #5 largest wind power plant of 65 in Australia by capacity.
Australia has 65 wind power plants in this dataset, together about 5,786 MW of capacity.
