Matters under consultation

AEMO has concluded its consultation on proposed changes (Changes) to the Generator Performance Standards (GPS) Template to implement the amendments to the National Electricity Rules (NER) under the:

  • National Electricity Amendment (Integrating energy storage systems into the NEM) Rule 2021 No. 13 (IESS Rule).
  • National Electricity Amendment (Efficient management of system strength on the power system) Rule 2021 No. 11 (EMSS Rule).

AEMO notes that the access standards underlying the GPS Template may be subject to further amendment as a result of a number of other ongoing reviews or consultation processes. The GPS Template changes currently proposed by AEMO focus only on the standards introduced or amended by the EMSS Rule and IESS Rule, and other minor and administrative changes.

In summary, the substantive proposed changes:

  • Incorporate two new access standards for short circuit ratio and voltage phase angle shift added by the EMSS Rule from 15 March 2023. 
  • Adjust the application of access standards in NER schedule 5.2 to reflect plant incorporating bidirectional units, that is taken to be an integrated resource system under the IESS Rule from 15 March 2023.

The updated GPS Template is now titled “Generator or Integrated Resource Provider Performance Standards template” and is available below and at AEMO’s Network Connections webpage.
