Tennant Creek — Australia

Tennant Creek is a 16.7 MW gas power plant in Northern Territory, Australia. It is operated by NT Government. Based on reported annual generation of 29 GWh, it can supply roughly 8.3k homes. It ranks #359 of 536 Australia power plants by installed capacity. Its modelled annual emissions are 33,842 t CO₂/yr (Climate TRACE), equivalent to about 7.9k 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 16.7 MW, Tennant 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.

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 hot desert climate (Köppen BWh) — Southern Hemisphere, latitude 19.7°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 100% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~7% 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

This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.

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.
