Our approval role
The cost allocation method is a document published by a network service provider which sets out how it will split shared costs between the different categories of services that it provides.
Each service provider is responsible for developing its principles and policies for attributing costs and these must be outlined in cost allocation method document submitted to us for approval.
The AER is required to assess cost allocation methods to ensure that they are in accordance with the requirements of the National Electricity Law and Rules and are consistent with the AER's Cost allocation guidelines for tranmission or distribution.
