Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Cranbourne's 11,402 solar systems typically avoid around 85.48 tonnes of CO₂ every hour during peak generation.

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

Cranbourne is one of Victoria's strongest solar communities, ranking 5th in the state — ahead of 99% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (1,694 systems, 4% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Cranbourne's solar community avoids an estimated 136,548 tonnes of CO₂ every year — equivalent to taking 65,023 cars off the road or powering around 27,310 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.
