On 18 May 2018, we released our final decision on TransGrid's transmission determination for the 2018-23 regulatory control period. We also published a fact sheet to accompany and summarise our final decision.
On 31 January 2023, the AER published its final decision on transmission pricing methodologies with amendments for system strength pricing (approved amended pricing methodology). The approved amended pricing methodology supersedes the pricing methodology approved in the AER’s 18 May 2018 final determination. All other aspects of the determination remain as per the AER’s 18 May 2018 final determination.
