Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Reservoir's 4,432 solar systems typically avoid around 33.23 tonnes of CO₂ every hour during peak generation.

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

Reservoir is one of Victoria's strongest solar communities, ranking 38th in the state — ahead of 95% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (246 systems, 5% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Reservoir's solar community avoids an estimated 53,077 tonnes of CO₂ every year — equivalent to taking 25,275 cars off the road or powering around 10,615 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.
