New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Sylvania's 1,337 solar systems typically avoid around 8.08 tonnes of CO₂ every hour during peak generation.

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

Sylvania ranks 255th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. 129 new systems were installed in the past 12 months, a 10% increase on the previous year — steady growth consistent with continued community uptake.

The combined impact is substantial: Sylvania's solar community avoids an estimated 12,907 tonnes of CO₂ every year — equivalent to taking 6,146 cars off the road or powering around 2,581 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.
