New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Eastwood's 2,432 solar systems typically avoid around 14.70 tonnes of CO₂ every hour during peak generation.

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

Eastwood sits in the top third of New South Wales for solar uptake, ranking 138th in the state out of 721 postcodes in the Clean Energy Regulator dataset. 221 new systems were installed in the past 12 months, a 14% increase on the previous year — steady growth consistent with continued community uptake.

The combined impact is substantial: Eastwood's solar community avoids an estimated 23,478 tonnes of CO₂ every year — equivalent to taking 11,180 cars off the road or powering around 4,696 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
