Matters under consultation

The focus of this consultation is to reflect the terminology in Onboarding and Connections Documents to be made with effect from 3 June 2024 for the purposes of the National Electricity Amendment (Integrating energy storage systems into the NEM) Rule 2021 No. 13 (IESS Rule) and National Electricity Amendment (Implementing integrating energy storage systems) Rule 2023 No. 2.

In summary, the Changes include the new terminology to meet the requirements of the IESS Rule.

Consultation process

AEMO considers the Changes to be minor or administrative in nature. The Changes make the Documents consistent with and aligned to the NER, as amended by the IESS Rule. The Changes which AEMO makes to an existing procedure, guideline or other document – including by inserting new NER clauses, updating existing material and providing additional clarity - will generally be considered to be minor or administrative, if those changes: 

  1. do not change the substantive rights or obligations of participants; 
  2. do not require participants to incur any costs or change their systems; 
  3. are not expected to involve material cost for AEMO; and 
  4. are straightforward and not contentious in nature. 

AEMO considers it important to request feedback on the Changes, in the interests of transparency. The marked up documents were published for consultation with stakeholders for 10 Business Days.

Final documents

AEMO has concluded consultation on proposed changes to the documents. There were no stakeholder submissions received, the draft documents have been finalised and published below.

AEMO notes that the changes made to the documents only focus on the IESS Rule and other minor and administrative changes. The documents are subject to further amendments as a result of a number of other ongoing reviews and subsequent consultation processes.

Other relevant consultations

AEMO has consulted on amendments to the System Strength Impact Assessment Guidelines (SSIAG), following the Australian Energy Market Commission’s (AEMC) final determination on Calculation of System Strength Quantity rule change.
