Queensland grid · community impact

Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Postcode 4478's 129 solar systems typically avoid around 0.80 tonnes of CO₂ every hour during peak generation.

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

Postcode 4478 ranks 363rd in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 129 registered systems to date. New installations eased in the past 12 months (15 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Postcode 4478's 129 solar systems avoid an estimated 1,277 tonnes of CO₂ per year — the equivalent of removing 608 cars from the road. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
