Retailers operating in Tasmania are required to pay a minimum feed-in tariff to customers for electricity exported to the grid from qualifying electricity generating systems.
The Regulator has conducted an investigation to determine a methodology for calculating the minimum feed-in tariff rates that are to apply during the three-year regulatory period that commences on 1 July 2025.
Determination and Final Report
On 12 May 2025, the Regulator made its 2025 Regulated Feed-in Tariff Rate Determination and released its Investigation Final Report. The Regulator also published a Media Release
The Final Report sets out the Regulator's decisions with regards to determining the minimum regulated feed-in tariff rate for small‑scale distributed generation (such as solar PV) for mainland Tasmania for each of the 2025-26, 2026-27 and 2027‑28 financial years.

The feed-in tariff rate for 2025-26 is provisionally estimated to be around 8.607 cents per kilowatt hour, 3.7 per cent lower than the rate for 2024-25. The final rate will be determined in mid‑June 2025.
In making its determination, the Regulator has maintained its previous approach of using the 'avoided cost' methodology. This methodology aims to ensure that customers with small-scale distributed generation systems (such as solar PV) receive a price for the electricity they export to the grid which reflects the value of that electricity to retailers.
Formula for calculating the regulated feed-in tariff rate for each financial year between 1 July 2025 and 30 June 2028
The minimum feed-in tariff rate to be paid by an authorised retailer to a feed-in tariff customer during the term of the Determination is to be calculated in accordance with the following formula which is set out in the 2025 Regulated Feed-in Tariff Rate Determination:
FiTy = (WEPy x MLFy x DLFy) + (AEMOy x DLFy)
Where:
FiTy is the regulated feed‑in tariff rate in c/kWh to be paid to feed-in tariff customers.
y is the relevant period.
WEPy is the wholesale electricity price calculated by the Regulator in accordance with the 2025 Standing Offer Determination, during the annual standing offer price approval process, expressed in c/kWh.
MLFy means the load weighted average marginal loss factor at the regional reference node for Tasmania for the relevant period as approved by the Regulator during the annual standing offer price approval process.
DLFy means the load weighted average distribution loss factor for Tasmania for the relevant period as approved by the Regulator during the annual standing offer price approval process.
AEMOy means the forecast charges, as billed by AEMO for market participation and ancillary services for each period that vary with the amount of wholesale electricity sold by authorised retailers, expressed in c/kWh. The Regulator will estimate AEMO charges for each period during the annual standing offer price approval process.
Draft Report
On 24 February 2025, the Regulator released its 2025 Regulated Feed-in Tariff Rate Investigation Draft Report and Draft Determination for consultation. The Draft Report was accompanied by a Media Release.
The Draft Report sets out the Regulator's intended approach to determining the regulated feed-in tariff rates for small-scale distributed generation for mainland Tasmania in each of the 2025-26, 2026-27 and 2027-28 financial years.
