Guidelines, schemes, models and reviews

Due to reforms, the AER is now responsible for determining the regulatory treatment of gas pipelines. The AER published a final Guide on 12 September 2023.

We have updated the Better Resets Handbook to accommodate the addition of the emissions reduction objective to the existing National Energy Objectives.

The gas pipeline information disclosure guidelines, price reporting guidelines and accompanying templates are required under the new Part 10 & 18A of the NGR.

The Ring-fencing guideline (electricity transmission) 2023 ensures the Guideline remains fit for purpose in a changing regulatory landscape and electricity mark

The Rate of Return Instrument (the Instrument) sets out the approach by which we will estimate the rate of return, and comprises the return on debt and the return on equity, as well as the value of imputation credits. We publish a new Instrument every 4 years that will bind all regulatory determinations in the subsequent 4 years.

This is the fifth topic in a series of working papers that we will produce as part of our pathway to the 2022 Rate of Return instrument. The outcomes from these working papers will feed in to the active phase of our 2022 Rate of Return instrument review.
