New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Barnawartha's 1,925 solar systems typically avoid around 11.63 tonnes of CO₂ every hour during peak generation.

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

Barnawartha sits in the top third of New South Wales for solar uptake, ranking 188th in the state out of 721 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (167 systems, 6% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Barnawartha's solar community avoids an estimated 18,584 tonnes of CO₂ every year — equivalent to taking 8,850 cars off the road or powering around 3,717 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.
