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.
Guide to AEMO information systems
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.
DWGM, STTM and retail gas (excluding WA) systems
The following documents are prerequisites for obtaining access to AEMO’s gas market systems.
User access
Use the Gas System User Access Request form below to apply for DWGM, STTM and Retail Gas (excluding WA) systems access for new participant users or to modify existing participant users.
For removal of access contact AEMO Information and Support Hub on 1300 236 600 or email supporthub@aemo.com.au.
Please note: This PDF form will soon be replaced by an online form accessible from the new Participant Services Portal.
If you are an existing DWGM, STTM and/or Retail Gas (excluding WA) market participant, you will be contacted by AEMO to register for access to the Participant Services Portal and begin using the new online form to apply for DWGM, STTM and Retail Gas (excluding WA) systems access for new participant users or to modify existing participant users.
After AEMO has contacted you and provided you a link to register for access to the portal, refer to the following two guides for assistance.
Self-service password management
The following document provides a guide to AEMO’s self-service password management system for participants.
APIs
This guide provides details about using AEMO’S e-Hub as an interface to communicate information with AEMO. It assists wholesale electricity and gas participants in developing their own APIs.
Data Interchange (DI)
Data Interchange is a set of cooperating applications to replicate data between AEMO’s Wholesale Market Systems and a participant’s RDBMS conforming to the Electricity and/or Gas Data Models.
Below are all the components necessary for a new installation of Data Interchange, bundled together into compressed files. Each bundle is for a specific RDBMS and the latest release of the Electricity and Gas Data Models.
Registered participants can also find Data Interchange software and guides on the Participant File Share, and on the Data Subscription section of the EMMS Markets Portal.
Data Interchange software
For Oracle 18c, please use 19c bundle.
