New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Thirroul's 2,067 solar systems typically avoid around 12.49 tonnes of CO₂ every hour during peak generation.

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

Thirroul sits in the top third of New South Wales for solar uptake, ranking 179th in the state out of 721 postcodes in the Clean Energy Regulator dataset. 165 new systems were added in the past 12 months, with growth of 4% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Thirroul's solar community avoids an estimated 19,955 tonnes of CO₂ every year — equivalent to taking 9,502 cars off the road or powering around 3,991 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.
