Western Australia grid · community impact

Based on last week's Western Australia grid mix (avg 630 gCO₂/kWh), Postcode 6121's 960 solar systems typically avoid around 4.63 tonnes of CO₂ every hour during peak generation.

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

Postcode 6121 ranks 119th in Western Australia for solar installations — in the middle tier of 388 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (40 systems, 34% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Postcode 6121's 960 solar systems avoid an estimated 7,391 tonnes of CO₂ per year — the equivalent of removing 3,520 cars from the road. 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.
