Gas systems guides
This page provides guides and information about aspects of AEMO’s gas market systems, including user access information, APIs, Data Interchange, Gas Data Model and the FRC Hub.
The Guide to Information Systems provides an overview of AEMO's market systems used by participants. It is relevant to IT decision-making during the registration process and provides an understanding of the IT systems requiring set-up.

Self-service password management
The following document provides a guide to AEMO’s self-service password management system for participants.
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.
Data Model Manager
The Data Model Manager is an application installed on your local admin machine to deliver Data Model upgrades, new installations, and defect fixes.
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.
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.
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
The Participant Data Replication (PDR) software is a component of Data Interchange, providing Registered Participants with the tools to replicate data from AEMO's systems.
The PDR software consists of the following applications:
Participant Data Replication Batcher (PdrBatcher), responsible for transferring files to and from AEMO's participant file server to participants' local Data Interchange folders.
Participant Data Replication Loader (PdrLoader), responsible for loading files to and from participant's local Data Interchange folders to the participant's DBMS. It can be installed in any environment supporting Java.
Participant Data Replication Monitor (PdrMonitor) is a web-based interactive interface allowing participants to configure and interrogate their Data Interchange instances. Participants install the software locally to run on either Windows or unix-like operating systems.
Full Retail Contestability (FRC) Hub
The FRC Hub is a communication infrastructure operated by AEMO. It provides a gateway through which AEMO and the retailers and distributors that participate in Queensland, Victorian, South Australian, New South Wales, Australian Capital Territory and, under contract, Western Australian retail markets can deliver and receive structured business-to-business messages utilising defined protocols and formats.
These messages cover various transactions, such as account creation, customer transfer notification, and meter data information.
