Metering coordinator
This section assists metering coordinators 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?
5MS changes:
- Engage with financially responsible market participants (FRMPs) and metering providers on the configuration and/or replacement of certain meters to enable 5-minute granularity.
- Facilitate the installation of new and replacement 5-minute capable type 4 meters installed from December 2018 (or December 2019 in the case of type 4A meters).
GS change:
- Assist with the resolution of any connection point or metering issues identified as part of UFE reporting, particularly cross-boundary metering.
-
How should we make these changes and when do we need make them?
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 co-ordinated 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.
Importantly, the Metering Transition Plan is the basis for participants, including MCs, to complete their own Metering Transition Plans. 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 directly applicable to MCs for 5MS/GS because the main rule obligations are for MPs to install and/or reconfigure certain meter types and MDPs to deliver 5-minute metering data.
The major procedure changes relevant to MCs for GS are related to LNSP MCs ensuring that non-contestable unmetered load NMIs are created.

Impact on MCs
Comment
MDM platform Yes Although there will be significant changes to MSATS standing data to support 5MS and GS, these changes will not be the responsibility of the MCs. However, MCs will need to be able to receive the process these notifications, including the new NMI Classification Codes. -
How and when do we test the market system changes?
The approach to and timing for participant 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 participant test phase.
There are no 5MS/GS test phases relevant for MCs. However, note that participants are responsible for:
- Testing their systems and processes that do not directly interact with AEMO’s market systems
- Arranging bilateral testing with other participants.
