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

Hallett Cove sits in the top third of South Australia for solar uptake, ranking 85th in the state out of 347 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (121 systems, 23% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Hallett Cove's 2,061 solar systems avoid an estimated 9,319 tonnes of CO₂ per year — the equivalent of removing 4,438 cars from the road. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
