Real-Time Market

The Real-Time Market, a co-optimised Energy and Essential System Services (ESS) market commenced on 1 October 2023.

Market Participants make Real-Time Market Submissions for Energy and ESS (Regulation Raise/Lower, Contingency Raise/Lower, and Rate of Change of Frequency Control Service (RoCoF Control Service)) offers.

Submissions made by Market Participants will be validated and, if valid, sent to the Dispatch Engine which will use them to determine the lowest overall cost of Dispatch to the Market.

Market Participants make Standing and Variation Real-Time Market Submissions for Energy and Essential System Services (ESS), via the WEMS Market Participant Interface (MPI) or an Application Programming Interface (API).

AEMO validates these submissions and informs Market Participants of the validation results (including a list of all errors when a submission is rejected). All submissions, acknowledgements, validation responses and relevant metadata are stored for reference, audit, and market compliance purposes.

Market Participants can view, query and download the submission data, and any related responses held by AEMO (both via the dedicated UI and APIs), and the latest submission data made available to the Dispatch Engine for the purposes of both Dispatch and Pre-Dispatch.
