This section assists metering providers in identifying the changes they need to make to implement 5MS and, where relevant, GS. It also provides links to the key information that triggers or supports the relevant changes.
The information provided by AEMO on 5MS and GS is general and may not be appropriate for any participant’s particular situation or market activities. Please also refer to AEMO’s privacy and legal notices.
At a high level, what are the 5MS/GS changes I need to make?
To implement 5MS and GS, Metering Providers (MPs) will need to:
- Assess their need for an accreditation update in consultation with AEMO
- Assess their need to apply for metering installation data storage exemptions and, where necessary, submit applications to AEMO
- As arranged by Metering Coordinators, install, replace or reconfigure meters to 5-minute trading intervals as required.
Create or update MSATS NMI standing data as required.
- Assist with the resolution of any connection point or metering issues identified as part of Unaccounted for Energy (UFE) publication.
How should we make these changes and when do we need make them?
The 5MS rule sets out the timeframes for installing and/or reconfiguring the different types of meters that will need to record and provide 5-minute data at various times.In addition, the Metering Transition Plan is the basis for participants, including MPs, to complete their own Metering Transition Plans.
In addition, the Metering Transition Plan is the basis for participants, including MPs, to complete their own Metering Transition Plans.
The Metering Transition Plan was developed in consultation with industry through the 5MS and GS Readiness Working Group (RWG) and its subsidiary Transition Focus Group (TFG). It provides coordinated guidance for AEMO and participants by setting out the expected responsibilities, detailed activities, dependencies and timeframes for completion for elements of the 5MS/GS metering transition.
Participants will individually develop and manage their physical metering and metering data activity based on the timeframes agreed in the plan.
Which AEMO procedures that are relevant to me have changed?
There have been no major procedure changes relevant to MPs for 5MS because the main obligations for MPs to install and/or reconfigure certain meter types are set out in the 5MS rule.
Similarly, there have been no major procedure changes relevant to MPs for GS. This is because the main obligation for MPs to install and/or reconfigure cross-boundary supply meters is set out in the GS rule.
Which AEMO systems that are relevant to me will change?
How and when do we test the market system changes?
The approach to and timing for market testing for 5MS and GS is set out in the Industry test and market trials strategy. It is supported by detailed test plans for each test phase.
Details on the timing and type of testing will be set out in the test plan to be developed in consultation with the Industry testing working group.
Note that participants are responsible for:
- Testing their systems and processes that interact directly or indirectly with AEMO’s market systems.
- Arranging bilateral testing with other participants.
