Cessnock is one of New South Wales's strongest solar communities, ranking 38th in the state — ahead of 95% of all New South Wales postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 413 new systems installed in the past 12 months — a 23% increase on the previous year, making Cessnock one of New South Wales's faster-growing solar postcodes.
The combined impact is substantial: Cessnock's solar community avoids an estimated 59,797 tonnes of CO₂ every year — equivalent to taking 28,475 cars off the road or powering around 11,959 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
