AER - Revocation and substitution of SA Power Networks' 2020-25 distribution determination - Letter

On 25 March 2024, the AER published its revocation and substitution determination for the for the 2020–25 regulatory control period. This corrected a material error relating to cable and conductor minor repairs that impacted our operating and capital expenditure decisions. This had flow on impacts to revenues, and the Demand Management Innovation Allowance Mechanism allowance and Service Target Performance Incentive Scheme incentive rates. 

All other aspects of the AER’s final determination remain as were made on 5 June 2020.

Our revocation and substitution determination, associated letter to SA Power Networks on this matter and the revised PTRM are below. The revised PTRM includes revenues approved in our Emergency standard cost pass through decision and annual updates for return on debt up to and including 2023–24 which can be found here.
