Port Stanvac

Oil power plant in South Australia, Australia. Approximate location -35.1104, 138.4915.

OilSouth AustraliaAustraliaEngineCO₂ modelled

Port Stanvac is a 65 MW oil power plant in South Australia, Australia. It is operated by Infratil Energy Australia Pty Ltd. Based on its capacity (estimated), it can supply roughly 49k homes (estimated). It ranks #234 of 536 Australia power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. Its modelled annual emissions are 3,453 t CO₂/yr (Climate TRACE), equivalent to about 805 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).

In context: how this plant compares

At 65 MW, Port Stanvac is well above the median oil plant in Australia (9 MW). Technically it is described as Engine. 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~3,453 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

805passenger cars driven for a year
450homes' yearly energy use
58ktree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Southern Hemisphere, latitude 35.1°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 49% 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: 29/100 — 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

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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
