Australian Capital Territory grid · community impact

Based on last week's Australian Capital Territory grid mix (avg 790 gCO₂/kWh), Postcode 2904's 2,693 solar systems typically avoid around 16.28 tonnes of CO₂ every hour during peak generation.

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

Postcode 2904 ranks 11th in Australian Capital Territory for solar installations — in the middle tier of 28 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (119 systems, 16% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Postcode 2904's solar community avoids an estimated 25,998 tonnes of CO₂ every year — equivalent to taking 12,380 cars off the road or powering around 5,200 average Australian homes with clean electricity. This is estimated using Australian Capital Territory's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
