On 3 October 2024, the Australian Energy Market Commission (AEMC) made the final rule for Providing flexibility in the allocation of interconnector costs. The final rule provides a mechanism which enables the allocation of interconnector costs between regions in the National Electricity Market as specified in agreements between Ministers.
We are required by the final rule to review, and if necessary, amend the pricing methodology guidelines and information guidelines for electricity transmission networks, to take into account the final rule.
On 1 April 2025, we published our draft amendments to our transmission pricing methodology guidelines. Our proposed amendments set out the information we require to assess whether electricity transmission networks’ pricing methodologies are consistent with the requirements of the final rule.
We also consider it necessary to update our information collection due to the final rule. Rather than amending the transmission information guidelines, we consider it appropriate to collect this additional information through additional data requirements (published for consultation alongside our proposed pricing methodology guidelines) in the Annual Information Orders for electricity transmission networks. This is consistent with our general approach to collecting other transmission information through the Orders.
