Portland ranks 464th in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 217 registered systems to date. New installations eased in the past 12 months (8 systems, 27% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Portland's 217 solar systems avoid an estimated 2,599 tonnes of CO₂ per year — the equivalent of removing 1,238 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.
