Data Interchange
Data interchange (DI) is a set of cooperating applications to replicate data between AEMO’s Wholesale Market Systems and registered participants' RDBMS conforming to the Electricity and/or Gas Data Models. AEMO recommends participants use the Data Interchange software (supplied by AEMO) to automate receiving and storage of the subscribed reports from Data Subscriptions. The data is conveniently stored in the participant's RDBMS conforming to the MMS Data Model.
Data Interchange software bundles
These packages have all the components necessary, including guides for each component, for a new installation of Data Interchange. Each bundle is for a specific RDBMS and latest release of the Electricity and Gas Data Models.
Data Interchange upgrade software
Here you can find the software components for upgrading an existing Data Interchange environment.
Data Interchange online help
All the Data Interchange documentation available on this page as PDF documents are now available as an online help.
Registered Participants can also find Data Interchange software and guides on the Participant File Share and EMMS Markets Portal > Data Subscription.

Electricity Data Model
The Electricity Data Model is the definition of the interface to participants for NEM wholesale data published by AEMO. A database conforming to the Electricity Data Model can contain a local copy of all current participant-specific data recorded in the main NEM database. The following guides explain the packages, tables, and reports in the Electricity Data Model.
- MMS Data Model Upgrade Report - Explains the changes in that Data Model version.
- MMS Data Model Report - Explains all Data Model tables in that version.
- MMS Data Model Package Summary - Explains the Data Model packages and associated tables.
- MMS Data Model Table to File Report - Explains the Data Model packages, reports, tables, file IDs, and versions contained in each file name.
Data Subscription
AEMO's wholesale system generates files continually, based on changes, five-minute dispatch runs, etc. These files (also known as reports) are typically comma-separated values (CSV) files. The files contain private and public data available to each participant. Using Data Subscription, participants can:
- Obtain the MMS Data Model scripts for building and maintaining their participant's RDBMS conforming to the MMS Data Model.
- Subscribe to the files made available by AEMO on the Participant File Server.
- Unsubscribe from any files that are no longer required.

Data Delivery
Status Dashboard
Displays the status of the Data Interchange components within a participant organisation. A list of filenames, delivery dates, and a file re-request count (where a file is sent to the participant's system more than once). Multiple file deliveries can indicate a problem at the participant's end.
Data Sharing
View data sharing arrangements you have with other Participant IDs. The Guide to Data Sharing explains how to share data with another participant ID using the Data Interchange software.
File delivery Summary
Allows participants to query all delivered files within a date range, request selected files re-delivered to the file server.
Performance Monitor
The performance monitor is a graphical view of the current Data Interchange environment run and managed by AEMO. Participants not receiving data, or experiencing data delays can contrast the data delivery performance of their Data Interchange environment to AEMO's Data Interchange performance environment.
Participant Data Replication Monitor
The Participant Data Replication Monitor (pdrMonitor) software is a component of Data Interchange, providing participants with visualisation of the status of their Data Interchange systems. The software is for Registered Participants using the Data Interchange software to replicate data between their systems and AEMO’s. Participants install, configure, and use the pdrMonitor on their local computers.
