Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Balwyn North's 1,850 solar systems typically avoid around 13.87 tonnes of CO₂ every hour during peak generation.

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

Balwyn North sits in the top third of Victoria for solar uptake, ranking 144th in the state out of 713 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (130 systems, 20% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Balwyn North's solar community avoids an estimated 22,155 tonnes of CO₂ every year — equivalent to taking 10,550 cars off the road or powering around 4,431 average Australian homes with clean electricity. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
