Greenough River Solar Farm is a 10 MW solar power plant in Western Australia, Australia. It is operated by Verve Energy/GE Energy Financial Services JV. Based on reported annual generation of 22 GWh, it can supply roughly 6,228 homes. It ranks #366 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).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Southern Hemisphere, latitude 28.9°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 78% 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: 21/100 — this site sits in the bottom 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 0.7% at warm-season highs here (estimate).

The #52 largest solar power plant of 69 in Australia by capacity.
Australia has 69 solar power plants in this dataset, together about 4,160 MW of capacity.
