Tasmania Carbon Intensity

Tasmania Grid Carbon Intensity

Tasmania consistently has the lowest grid carbon intensity of any Australian electricity region, with hydroelectric generation supplying over 90 per cent of the state's power. The grid regularly achieves intervals of zero emission intensity when hydro, wind, and other renewables supply all demand — a pattern that occurs across multiple hours on most days.

The primary factor affecting Tasmania's intensity is the Basslink HVDC undersea cable connecting the state to Victoria. When Tasmania is importing electricity from the mainland, the effective intensity rises to reflect the emission profile of Victorian generation. When exporting surplus hydro generation, Tasmania's own intensity remains near zero.

Tasmania's consistently low carbon intensity makes it an attractive location for emissions-sensitive operations. However, organisations should account for Basslink import periods in their Scope 2 calculations, as these intervals carry the emission profile of mainland generation.
