Standing Offer Price Approvals
The Regulator is required to approve the maximum standing offer prices a regulated offer retailer may charge small customers on mainland Tasmania (including Bruny Island) for services provided under standard retail contracts.
Standing offer prices are adjusted each year in accordance with the requirements outlined in the relevant standing offer determination, standing offer price approval guideline and standing offer price strategy.
Wholesale Electricity Price (WEP)
The Tasmanian Economic Regulator calculates the WEP in accordance with section 40AB of the Electricity Supply Industry Act 1995 applying the method set out in the relevant Annual Standing Offer Price Approval Guideline. The method uses the weekly load following swap prices calculated in accordance with the Wholesale Contract Regulatory Instrument.
The method for calculating the WEP was changed as a result of the 2025 Standing Offer Price Investigation with the applicable weekly volume no longer the Absolute Minimum Capacity Offer Volume shown in Schedule 1 of the Wholesale Contract Regulator Instrument.
The weekly volumes used to calculate the WEP under the 2025 standing offer price determination are based on a combination of small customer net system load profile and interval meter volume provided by AEMO. As the interval meter data is not publicly available the Regulator will publish the applicable small customer quarterly profile. This will enable interested parties to calculate the WEP.
The small customer quarterly profile for the 2025-26 WEP calculation is as follows:
