Tasmania has the most distinctive generation mix in the NEM, with hydroelectric power supplying over 90% of the state's electricity. This gives Tasmania the lowest carbon intensity and the most stable wholesale prices of any Australian region. The state's hydro fleet (including Gordon, Poatina, Reece and numerous smaller stations) provides fully dispatchable renewable generation.
Wind generation supplements the hydro fleet, with farms at Musselroe, Woolnorth and other sites contributing during periods of strong wind. Together, hydro and wind regularly deliver 100% renewable generation for extended periods, a milestone that remains rare in other NEM regions.
The Basslink HVDC cable connects Tasmania to Victoria, allowing the state to export surplus hydro generation when prices are high on the mainland, or import electricity when dam levels are low. The direction and magnitude of Basslink flows significantly influence Tasmania's effective generation mix.
Tasmania’s generation mix is over 90% hydroelectric, the most distinctive fuel profile of any NEM region, supplemented by wind farms at sites including Musselroe and Woolnorth. The live fuel-type breakdown is shown above.
Hydro and wind together regularly deliver 100% renewable generation for extended periods in Tasmania, a milestone that remains rare in other NEM regions.
The Basslink HVDC cable allows Tasmania to export surplus hydro generation to Victoria when mainland prices are high, or import electricity when dam levels are low, which shifts the state’s effective generation mix.
gridIQ refreshes the Tasmanian generation mix from AEMO SCADA and ASEFS rooftop-solar data every 30 minutes, matching the underlying generation-mix ingest cadence.
