Western Australia grid · community impact

Based on last week's Western Australia grid mix (avg 630 gCO₂/kWh), Postcode 6122's 6,799 solar systems typically avoid around 32.77 tonnes of CO₂ every hour during peak generation.

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

Postcode 6122 is one of Western Australia's strongest solar communities, ranking 21st in the state — ahead of 95% of all Western Australia postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (467 systems, 3% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Postcode 6122's solar community avoids an estimated 52,344 tonnes of CO₂ every year — equivalent to taking 24,926 cars off the road or powering around 10,469 average Australian homes with clean electricity. This is estimated using Western Australia's average grid emissions intensity of 630 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
