Australian Capital Territory grid · community impact

Based on last week's Australian Capital Territory grid mix (avg 790 gCO₂/kWh), Postcode 2903's 1,623 solar systems typically avoid around 9.81 tonnes of CO₂ every hour during peak generation.

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

Postcode 2903 ranks 14th in Australian Capital Territory for solar installations — in the middle tier of 28 postcodes tracked by the Clean Energy Regulator across the state. 89 new systems were added in the past 12 months, with growth of 3% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Postcode 2903's solar community avoids an estimated 15,668 tonnes of CO₂ every year — equivalent to taking 7,461 cars off the road or powering around 3,134 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.
