Cluny is a 17 MW hydro power plant in Tasmania, Australia. It is operated by Hydro-Electric Corporation (Tasmania). Based on reported annual generation of 18 GWh, it can supply roughly 5.2k homes. It ranks #357 of 536 Australia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 4.3% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

In context: how this plant compares
At 17 MW, Cluny is below the median hydro plant in Australia (45 MW). Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Southern Hemisphere, latitude 42.5°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 5% above 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: 52/100 — this site sits in the mid 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
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
