Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Castlemaine's 539 solar systems typically avoid around 4.04 tonnes of CO₂ every hour during peak generation.

Grid intensity data: Open Electricity (openelectricity.org.au) · 7-day average · updates monthly

Castlemaine ranks 337th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (11 systems, 52% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Castlemaine's 539 solar systems avoid an estimated 6,455 tonnes of CO₂ per year — the equivalent of removing 3,074 cars from the road. 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.
