Western Australia grid · community impact

Based on last week's Western Australia grid mix (avg 630 gCO₂/kWh), Balcatta's 3,751 solar systems typically avoid around 18.08 tonnes of CO₂ every hour during peak generation.

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

Balcatta sits in the top third of Western Australia for solar uptake, ranking 48th in the state out of 388 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (180 systems, 18% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Balcatta's solar community avoids an estimated 28,878 tonnes of CO₂ every year — equivalent to taking 13,751 cars off the road or powering around 5,776 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.
