New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Oatley's 1,554 solar systems typically avoid around 9.39 tonnes of CO₂ every hour during peak generation.

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

Oatley ranks 228th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (109 systems, 32% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Oatley's solar community avoids an estimated 15,002 tonnes of CO₂ every year — equivalent to taking 7,144 cars off the road or powering around 3,000 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.
