Five Minute Settlement
The Australian Energy Market Operator (AEMO) is working with industry to implement changes arising from an Australian Energy Market Commission (AEMC) Final Determination to implement Five-Minute Settlement (5MS) in the National Electricity Market (NEM), which will commence on 1 July 2021. AEMO has also submitted a rule change to the AEMC to consider the merits of Global Settlement (GS), and consultation on the rule change is expected to commence in June 2018.
To implement the 5MS (and potentially the GS) rule change AEMO has established the 5MS Program, comprising the following workstreams:
- Procedures – to define the required changes to market procedures.
- Systems – to design, develop, test, and implement changes to AEMO’s market systems.
- Readiness – to coordinate, assist and prepare AEMO and the industry for the transition.
- Five-Minute Settlement Meetings and Forum Dates (31 KB, xlsx)
For further information about the program please visit the Program Information and Fact Sheets page.
