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

Rockhampton sits in the top third of Queensland for solar uptake, ranking 49th in the state out of 449 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (411 systems, 19% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Rockhampton's solar community avoids an estimated 69,358 tonnes of CO₂ every year — equivalent to taking 33,028 cars off the road or powering around 13,872 average Australian homes with clean electricity. 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.
