Dispatch and market notices

Dispatch Advisories and market notices play an important role in alerting participants to issues in the Wholesale Electricity Market (WEM). This page provides an overview of when the alerts are published, and what information is contained in the notification.

Information about WEM Systems (WEMS) releases is provided on the IT change and release management page.

Dispatch Advisories

AEMO System Management must inform Market Participants and Network Operators of impending or current situations that have potential Power System Security ramifications. AEMO does this by issuing Dispatch Advisories under clause 7.11.5 of the WEM Rules, and when the Operating State of the South West Interconnected System (SWIS) is expected to, or has, changed.

Market Participants are obliged to keep AEMO informed of any circumstances they become aware of that may require a Dispatch Advisory.

The advisory

A Dispatch Advisory includes a statement of the Operating State (Normal, High-Risk, or Emergency) during the period to which the Dispatch Advisory relates. It includes information on how Market Participants should respond to the situation.

The Market Rules recognise that sometimes AEMO has to react so quickly to a situation that it is not able to issue a Dispatch Advisory until after the event.

Real-time Dispatch Advisories can be downloaded from the Market Data site.

Market advisories

AEMO must inform Market Participants of impending situations that could impact market outcomes. It does this by issuing market advisories in the following situations:

• Market system outages, whereby aspects of the market cannot run normally due to systems failures.
• Notification of suspension of any aspect of the market.

Note that advisories related to dispatch are provided in AEMO's Dispatch Advisories.

The advisory

Market advisories include information on how market participants should respond to the situation.

Market advisories can be downloaded from the Market Data site.

WEMS notices

The information provided below aims to keep users apprised of the latest system changes, status of participant change requests, API documentation, technical bulletins, end-of-life notices, and scheduled system outages.

Environments

The table below details the release and build which is currently running in each environment. The snapshot date indicates the date at which the last snapshot of live market data was taken for the environment, as applicable.

Trial environments can simulate the operation of the WEM, but actual market outcomes may vary in these environments due to testing activities of Market Participants and AEMO, differences in software versions, and the time since the last snapshot.
