A hydro-powered island grid
Tasmania is part of the National Electricity Market and is connected to the mainland by the Basslink interconnector, but its generation mix is unlike anywhere else in Australia. The overwhelming majority of Tasmania’s electricity comes from hydro power, supplemented by wind, which makes it one of the greenest grids in the country.
Hydro gives Tasmania a stable, largely renewable supply, but it is exposed to rainfall and dam levels. In dry years the state may need to import power over Basslink or run backup generation, which feeds into wholesale costs. The interconnector also links Tasmanian wholesale prices to the mainland market.
Aurora Energy and limited competition
For residential customers, Aurora Energy is effectively the retailer in Tasmania — full retail competition for households has not meaningfully opened, so most Tasmanians do not have a field of retailers to switch between the way NSW or Victorian customers do. This is an important expectation to set: shopping around for a cheaper retailer is largely not an option for Tasmanian households.
The single distribution network is run by TasNetworks, which operates the poles and wires across the state. As with other regulated markets, the network portion of the bill is set by regulation rather than competition.
The regulated standing-offer price
Because household competition is limited, Tasmania relies on a regulated standing-offer price. The Tasmanian Economic Regulator oversees regulated retail prices, so what most households pay is a regulated tariff rather than a competitively won market rate. This gives price certainty but means the usual "switch and save" lever is largely absent.
Tasmania also offers time-based tariff options and specific tariffs for things like heating and hot water, which reflect the state’s cold climate and heavy reliance on electric heating. Choosing the right combination of tariffs for your household can make a real difference even without a retailer to switch to.
Where Tasmanian households can save
With switching largely off the table, the savings levers sit on your side of the meter: getting onto the most suitable tariff mix, reducing usage — heating is usually the biggest single load in a Tasmanian home — improving insulation and heating efficiency, and adding rooftop solar where the roof and budget allow.
Concessions are the other big lever. Tasmania runs its own energy concessions for eligible households, applied through your Aurora Energy account. EnergySorted’s retailer-switching engine is built for the competitive mainland markets, so it will not find you a new Tasmanian retailer — but its guidance on tariffs, usage reduction and concessions is where Tasmanian households should concentrate.
