About data subscription

Overview

AEMO's systems generate 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.

AEMO recommends participant use the EMMS Data Interchange products (supplied by AEMO) to automate receiving and storage of the subscribed reports from Data Subscriptions. The data is conveniently stored on the participant's DBMS conforming to the Electricity Data Model, for further information, see Data Interchange.

AEMO communicates changes to participants in release schedules and technical specification published on AEMO's website > Electricity or Gas IT systems > IT Change and Release Management.

Data Subscription contains the Data Model files to populate your local DBMS and the non-Data Model files you can also subscribe to. It is a component of Data Interchange (see Figure 6) and the EMMS Markets Portal.
