In 2007, the AER published its transmission pricing methodology guidelines.
The guidelines were amended on 17 July 2014 to include a new section (section 2.6). This was following a rule change introducing inter-regional transmission charging arrangements. No other amendments were made.
In accordance with the National Electricity Rules, transmission network service providers are required to submit to the AER a proposed pricing methodology relating to prescribed transmission services which are subject to a transmission determination. The AER is required to assess whether the proposed pricing methodology is consistent with the pricing principles for prescribed transmission services outlined in rule 6A.23 of the NER and the AER’s pricing methodology guidelines.
