Participant IT interfaces
AEMO has numerous systems with multiple interfaces to provide for the needs of all participants. Access to some systems depends on a participant’s registration category.
Systems are available to participants in accordance with the NEM rules and procedures. Access is 24/7, except for notified periods of system maintenance and unplanned outages. AEMO constantly monitors its information systems to ensure performance standards are met.
There are pre-production and production environments, each separately maintained. New features are added to pre-production first, and announced in change notices and technical specifications. The pre-production environments are intended for participant testing and training purposes.
The interfaces include: file upload (HTTPS), web portals (HTTPS), file server (FTP), web services (HTTPS), and AEMO's website (HTTP).
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 developing their own APIs.

Its primary function is to provide sufficient information to allow participants to understand the csv data format used for exchanging data with AEMO.
Web services is an additional option to the web portals and file interfaces for system-to-system interaction with AEMO's systems. There are web services for both the retail and wholesale systems.
