Portland ranks 464th in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 216 registered systems to date. Growth has been strong, with 11 new systems installed in the past 12 months — a 22% increase on the previous year, making Portland one of Victoria's faster-growing solar postcodes.
Collectively, Portland's 216 solar systems avoid an estimated 2,587 tonnes of CO₂ per year — the equivalent of removing 1,232 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.
