Argyle Diamond Mine is a 32 MW oil power plant in Western Australia, Australia. It is operated by Rio Tinto - Argyle Diamond Mines. Based on its capacity (estimated), it can supply roughly 24k homes (estimated). It ranks #301 of 536 Australia power plants by installed capacity. Its modelled annual emissions are 29,677 t CO₂/yr (Climate TRACE), equivalent to about 6.9k cars driven for a year. In context, oil supplies about 2.2% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

At 32 MW, Argyle Diamond Mine is well above the median oil plant in Australia (9 MW). Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot semi-arid steppe climate (Köppen BSh) — Southern Hemisphere, latitude 16.7°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
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.
