South Australia grid · community impact

Based on last week's South Australia grid mix (avg 370 gCO₂/kWh), Blackwood's 4,040 solar systems typically avoid around 11.44 tonnes of CO₂ every hour during peak generation.

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

Blackwood is one of South Australia's strongest solar communities, ranking 21st in the state — ahead of 94% of all South Australia postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (232 systems, 3% below the previous year), a natural slowdown after earlier periods of stronger uptake.

The combined impact is substantial: Blackwood's solar community avoids an estimated 18,267 tonnes of CO₂ every year — equivalent to taking 8,699 cars off the road or powering around 3,653 average Australian homes with clean electricity. 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.
