On 26 November 2021, the AER revoked and substituted the 2020-25 determinations for Energex, Ergon Energy and SA Power Networks to correct an error in the control mechanism attachments to facilitate an appropriate transition from the previous version of the service target performance incentive scheme (STPIS 1.2) to its latest version (STPIS 2.0).
This decision will ensure businesses do not over-recover through the STPIS incentive scheme, ensuring consumers pay no more than necessary.
The substitute determinations will apply for the remainder of the regulatory control period. All other aspects of the determination remain as per the AER’s final determination which was originally made on 5 June 2020.
