Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Dandenong South's 3,573 solar systems typically avoid around 26.79 tonnes of CO₂ every hour during peak generation.

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

Dandenong South is one of Victoria's strongest solar communities, ranking 51st in the state — ahead of 93% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (177 systems, 23% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Dandenong South's solar community avoids an estimated 42,790 tonnes of CO₂ every year — equivalent to taking 20,376 cars off the road or powering around 8,558 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.
