The AER has today published its 2023 Rate of Return update which illustrates annual changes in market data for the businesses we regulate.
The data presented in the update is gathered in accordance with the 2022 Rate of Return Instrument, which sets out the method used by the AER to determine the rate of return for the businesses we regulate. The Rate of Return Instrument uses timely market data in its development.
We started publishing annual data updates in 2019, to show changes in market data since our 2018 Instrument. In our 2022 Instrument we committed to continue these updates annually going forward.
The annual data update published today shows changes in market data since the publication of the 2022 Instrument. The intent of the data update is to provide a foundation for substantive discussion with all stakeholders during the active phase of the 2026 Rate of Return Instrument review.
