Transmission Revenue Reset Process

As a regulated business, we are required to lodge a Revenue Proposal with the Australian Energy Regulator (AER) by 31 October 2020 setting out our proposed revenues and investment plans for the five-year regulatory period commencing 1 April 2022. The process for setting our revenue is referred to as the Transmission Revenue Reset (TRR). Our next five-year regulatory period for electricity transmission runs from 1 April 2022 to 31 March 2027. 


Customer Advisory Panel

AusNet Services has established its first TRR Customer Advisory Panel to ensure that, to the extent possible, our Revenue Proposal reflects customers’ views and preferences. The Panel comprises of representatives from a range of customer advocacy groups, clean energy bodies, generators and the Victorian distribution businesses.


The Panel will be complemented by other customer engagement activities we intend to undertake, such as consultation with our existing Customer Consultative Committee (CCC) and one-on-one interviews with large customers.
