New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Silverwater's 229 solar systems typically avoid around 1.38 tonnes of CO₂ every hour during peak generation.

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

Silverwater ranks 514th in New South Wales out of 721 postcodes in the Clean Energy Regulator dataset, with 229 registered systems to date. New installations eased in the past 12 months (14 systems, 7% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Silverwater's 229 solar systems avoid an estimated 2,211 tonnes of CO₂ per year — the equivalent of removing 1,053 cars from the road. 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.
