Guidelines, schemes, models and reviews

Expenditure Forecast Assessment Guideline describe the process, techniques and associated data requirements for our approach to setting efficient expenditure

AER updated its capital expenditure incentives guideline and efficiency benefit sharing scheme to accommodate the amended National Energy Objectives.

The CESS provides financial rewards to network service providers whose capex becomes more efficient and financial penalties for those that become less efficient

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.

The Ring-fencing guideline (electricity distribution) 2022 ensures the Guideline remains fit for purpose in a changing regulatory landscape and electricity mark

The rate of return annual updates provide stakeholders with rate of return data, particularly time series market data showing changes since the 2018 Instrument.

The AER has released a Guidance Note explaining our non-network ICT capex forecast assessment approach.
