New South Wales grid · community impact

Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Forster's 943 solar systems typically avoid around 5.70 tonnes of CO₂ every hour during peak generation.

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

Forster ranks 304th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (50 systems, 32% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Forster's 943 solar systems avoid an estimated 9,104 tonnes of CO₂ per year — the equivalent of removing 4,335 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.
