Bacchus Marsh is one of Victoria's strongest solar communities, ranking 41st in the state — ahead of 94% of all Victoria postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 312 new systems installed in the past 12 months — a 20% increase on the previous year, making Bacchus Marsh one of Victoria's faster-growing solar postcodes.
The combined impact is substantial: Bacchus Marsh's solar community avoids an estimated 49,604 tonnes of CO₂ every year — equivalent to taking 23,621 cars off the road or powering around 9,921 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.
