New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Cessnock's 5,863 solar systems typically avoid around 35.43 tonnes of CO₂ every hour during peak generation.

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

Cessnock is one of New South Wales's strongest solar communities, ranking 40th in the state — ahead of 94% of all New South Wales postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (417 systems, 11% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Cessnock's solar community avoids an estimated 56,601 tonnes of CO₂ every year — equivalent to taking 26,953 cars off the road or powering around 11,320 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.
