Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Knox's 4,650 solar systems typically avoid around 34.86 tonnes of CO₂ every hour during peak generation.

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

Knox is one of Victoria's strongest solar communities, ranking 32nd in the state — ahead of 96% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (318 systems, 12% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Knox's solar community avoids an estimated 55,687 tonnes of CO₂ every year — equivalent to taking 26,518 cars off the road or powering around 11,137 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.
