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

Rochester ranks 427th 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 (9 systems, 67% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Rochester's 296 solar systems avoid an estimated 3,545 tonnes of CO₂ per year — the equivalent of removing 1,688 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.
