South Australia grid · community impact

Based on last week's South Australia grid mix (avg 370 gCO₂/kWh), West Lakes's 1,793 solar systems typically avoid around 5.08 tonnes of CO₂ every hour during peak generation.

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

West Lakes sits in the top third of South Australia for solar uptake, ranking 102nd in the state out of 347 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (83 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, West Lakes's 1,793 solar systems avoid an estimated 8,107 tonnes of CO₂ per year — the equivalent of removing 3,860 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.
