Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Balwyn's 1,211 solar systems typically avoid around 9.08 tonnes of CO₂ every hour during peak generation.

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

Balwyn ranks 218th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. 89 new systems were added in the past 12 months, with growth of 3% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Balwyn's solar community avoids an estimated 14,503 tonnes of CO₂ every year — equivalent to taking 6,906 cars off the road or powering around 2,901 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.
