New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Postcode 2318's 3,902 solar systems typically avoid around 23.58 tonnes of CO₂ every hour during peak generation.

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

Postcode 2318 sits in the top third of New South Wales for solar uptake, ranking 88th in the state out of 721 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 348 new systems installed in the past 12 months — a 26% increase on the previous year, making Postcode 2318 one of New South Wales's faster-growing solar postcodes.

The combined impact is substantial: Postcode 2318's solar community avoids an estimated 37,670 tonnes of CO₂ every year — equivalent to taking 17,938 cars off the road or powering around 7,534 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.
