On 23 April 2026, the Australian Energy Market Commission (AEMC, or the Commission) made a final rule to improve metering and metrology arrangements in the National Electricity Rules (NER). The final rule is in response to three rule change requests submitted by AEMO, which have been consolidated.

These are:
ERC0414 Flexible communication requirements for SAPS generation connection points
ERC0413  Refining the eligibility requirements for Secondary Settlement Points
ERC0409 Consultation requirements for the Metrology Procedures

The final rule will commence on 30 April 2026.

The final rule will address three key areas.

The final rule will allow flexible communications requirements for SAPS generation connection points
Firstly, the rule will allow the use of type 4A (manual-read) meters for standalone power system (SAPS) generation points with a single generator connection. We consider this will reduce installation and operation costs for Market SAPS Resource Providers (MSRPs) without
compromising settlement integrity or affecting other market participants and end users.

The final rule will refine eligibility requirements for SSPs
Secondly, the rule will replace the list of eligible connection point metering types with a general requirement for meters with remote acquisition capability for trading interval data. This will allow all customers across the National Energy Market (NEM), including Victoria, to benefit from Secondary Settlement Points (SSPs), as envisioned in the Unlocking CER benefits through flexible trading rule change.

The final rule will streamline consultation requirements for the Metrology Procedures
Lastly, the rule will remove the mandatory three-month period between the publication and commencement of any amendments under the Metrology Procedures. This will harmonise the process for changing Metrology Procedures with the standard Rules consultation procedures
which are used throughout the NER, and which include obligations for consulting on the date on which amendments will commence.
