Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Postcode 3903's 198 solar systems typically avoid around 1.48 tonnes of CO₂ every hour during peak generation.

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

Postcode 3903 ranks 473rd in Victoria out of 713 postcodes in the Clean Energy Regulator dataset, with 198 registered systems to date. New installations eased in the past 12 months (12 systems, 8% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Postcode 3903's 198 solar systems avoid an estimated 2,371 tonnes of CO₂ per year — the equivalent of removing 1,129 cars from the road. 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.
