Tasmania Electricity Tariff Stabilisation Bill 2026 Aims to Cap Household Power Costs
The bill would alter how distribution charges are calculated for homes across Hobart, Launceston and the north-west coast from mid-2027.
How we reported this
The Tasmanian Electricity Tariff Stabilisation Bill 2026, introduced in the House of Assembly on 6 July, changes the way network charges are passed through to residential customers. It requires the state-owned distribution business to absorb a portion of transmission cost increases tied to the Marinus Link project rather than recovering them fully through quarterly bills.
Why the change arrives now
Electricity network costs have risen in the 2025-26 financial year after the Australian Energy Regulator approved higher returns on capital for Basslink and related infrastructure. The 2025-26 Tasmanian Budget Papers record that average annual household electricity expenditure in Hobart reached $2,450. Policy analysts note the bill responds to sustained pressure on fixed incomes in regional postcodes where winter heating demand remains highest.
Under the legislation, the first 500 kilowatt-hours each quarter would be charged at the current network rate while any usage above that threshold attracts a reduced uplift. Local advocates note this structure directly affects single-income households in Clarence and Glenorchy, where average quarterly consumption sits near 1,800 kilowatt-hours during July to September.
Next steps in the legislative process
The bill is scheduled for committee stage on 15 July. If passed unamended, the new tariff rules would take effect on 1 July 2027 and apply automatically to all Aurora Energy residential accounts. The government says the policy will require the Treasurer to table an annual report on realised savings for households in each Tasmanian statistical area.
Budget modelling released with the bill projects a reduction of $180 to $240 in annual network charges for the median Tasmanian household consuming 7,200 kilowatt-hours a year. The figures are drawn from the same consumption data used in the 2025-26 state budget.
