Market IT systems

IT change and release management

This page lists schedules for IT changes and releases across AEMO’s electricity and gas market systems. All change management is governed under the IT Change Management Policy and Procedure.

IT changes

AEMO’s IT change schedule informs AEMO participants in advance about IT changes and provides a consolidated view of the changes planned. This is another step towards standardising the maintenance and outage windows for AEMO’s market-facing systems, helping to better manage any impact as well as overall planning of changes and releases.

Forward schedule of IT changes

The fortnightly forward schedule of IT changes lists all planned maintenance, as well as the status history of each of AEMO’s business services.
