Corio is one of Victoria's strongest solar communities, ranking 56th in the state — ahead of 92% of all Victoria postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 410 new systems installed in the past 12 months — a 22% increase on the previous year, making Corio one of Victoria's faster-growing solar postcodes.
The combined impact is substantial: Corio's solar community avoids an estimated 41,927 tonnes of CO₂ every year — equivalent to taking 19,965 cars off the road or powering around 8,385 average Australian homes with clean electricity. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
