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

West Lakes ranks 152nd in South Australia for solar installations — in the middle tier of 347 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (27 systems, 39% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, West Lakes's 820 solar systems avoid an estimated 3,708 tonnes of CO₂ per year — the equivalent of removing 1,766 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.
