Mintaro

Gas power plant in South Australia, Australia. Approximate location -33.9031, 138.7383.

GasSouth AustraliaAustraliaOCGTCO₂ modelled

Mintaro is a 90 MW gas power plant in South Australia, Australia. It is operated by Synergen Power. Based on reported annual generation of 42 GWh, it can supply roughly 12k homes. It ranks #193 of 536 Australia power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. Its modelled annual emissions are 39,212 t CO₂/yr (Climate TRACE), equivalent to about 9.1k 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).

In context: how this plant compares

At 90 MW, Mintaro is below the median gas plant in Australia (106 MW). Technically it is described as OCGT. 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.

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

~39,212 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

9.1kpassenger cars driven for a year
5.1khomes' yearly energy use
654ktree seedlings grown 10 years to absorb it

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 33.9°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 39% 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: 34/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~0% 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.

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 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.
