HEZ Energy Peaking Power Plant is a 120 MW oil power station in New South Wales, Australia. It is operated by Hunter Investment Corporation Pty Ltd. Based on its capacity (estimated), it can supply roughly 90k homes (estimated). It ranks #160 of 536 Australia power plants by installed capacity. Its modelled annual emissions are 118,704 t CO₂/yr (Climate TRACE), equivalent to about 28k 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 120 MW, HEZ Energy Peaking Power Plant 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.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 32.8°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 61% 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: 26/100 — 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.
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 corrosive environment (estimated ISO 9223 class C4 — High), 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.
The #4 largest oil power plant of 46 in Australia by capacity.
Australia has 46 oil power plants in this dataset, together about 1,605 MW of capacity.
