The Australian Energy Regulator (AER) has today released an amended Rate of Return Instrument.
This amendment was required due to a data source prescribed in the Instrument becoming unavailable. Specifically, the Reserve Bank of Australia (RBA) stopped publishing its F16 data series, Indicative Mid Rates of Australian Government Securities, on 31 March 2023.
The AER publicly consulted on the amendment prior to making our final decision and considered submissions received as part of this process.
In the absence of RBA’s F16 data series, the amended Instrument will now use an alternative data series as set out in the Instrument.
The final amended Instrument applies to regulatory determinations from now until it is remade.
