4,325 solar installations registered with the Clean Energy Regulator · ranked top 5% in Northern Territory · data current as at 2026-04-03
Based on last week's Northern Territory grid mix (avg 640 gCO₂/kWh), Casuarina's 4,325 solar systems typically avoid around 21.18 tonnes of CO₂ every hour during peak generation.

Casuarina is one of Northern Territory's strongest solar communities, ranking 1st in the state — ahead of 98% of all Northern Territory postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 186 new systems installed in the past 12 months — a 26% increase on the previous year, making Casuarina one of Northern Territory's faster-growing solar postcodes.
The combined impact is substantial: Casuarina's solar community avoids an estimated 33,826 tonnes of CO₂ every year — equivalent to taking 16,108 cars off the road or powering around 6,765 average Australian homes with clean electricity. This is estimated using Northern Territory's average grid emissions intensity of 640 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
