Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Reservoir's 2,185 solar systems typically avoid around 16.38 tonnes of CO₂ every hour during peak generation.

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

Reservoir sits in the top third of Victoria for solar uptake, ranking 118th in the state out of 713 postcodes in the Clean Energy Regulator dataset. 136 new systems were added in the past 12 months, with growth of 1% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Reservoir's solar community avoids an estimated 26,167 tonnes of CO₂ every year — equivalent to taking 12,460 cars off the road or powering around 5,233 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.
