Victoria grid · community impact

Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Berwick's 1,434 solar systems typically avoid around 10.75 tonnes of CO₂ every hour during peak generation.

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

Berwick sits in the top third of Victoria for solar uptake, ranking 191st in the state out of 713 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (83 systems, 22% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Berwick's solar community avoids an estimated 17,173 tonnes of CO₂ every year — equivalent to taking 8,178 cars off the road or powering around 3,435 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.
