SolarAustralian Capital TerritoryAustralia

Williamsdale is a 7 MW solar power plant in Australian Capital Territory, Australia. Based on its capacity (estimated), it can supply roughly 2,978 homes (estimated). It ranks #390 of 512 Australia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 19.6% of Australia's electricity; the national grid averages 525 gCO₂/kWh (38.6% low-carbon) (2025).

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a temperate oceanic climate (Köppen Cfb) — Southern Hemisphere, latitude 35.6°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 2% 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: 51/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).
