Real Time Market Submissions

The Real Time Market Submission (RTMS) project transformed the way that Market Participants make Submissions in the new Real-Time Market.

The superseded submission structures for the Balancing and LFAS Markets were fundamentally different to what is required to support the new SCED Market design. The RTMS project developed a new submission mechanism for both Energy and ESS (Regulation Raise/Lower, Contingency Raise/Lower, and Rate of Change of Frequency (RoCoF) bids and offers).

Submissions made by Market Participants are validated and, if valid, sent to the dispatch engine which uses them to determine the lowest overall cost of dispatch to the market.

RTMS provides new submission functionalities for Market Participants and allows: 

  • Market Participants to make Standing and Variation Real-Time Market Submissions for Energy and Essential System Services (ESS), both via a Web User Interface (UI) and an Application Programming Interface (API). Submissions can be made for multiple Facilities Real-Time Market Services in one go.
  • AEMO validates these submissions and informs Market Participants of the validation results (including a list of all errors when a submission is rejected).
  • AEMO stores all submissions, acknowledgements, validation responses and relevant metadata for reference, audit, and market compliance purposes. 
  • Both AEMO and Market Participants can view, query and download the submission data, and any related responses held by AEMO (both via the dedicated UI and APIs).
  • The latest submission data is made available to the dispatch engine in a suitable format for the purposes of both Dispatch and Pre-Dispatch.

The new system features a new, more user-friendly Market Participant User Interface, which is accessible in WEMS MPI. Also, new API endpoints have been created and made available to Market Participants to send submissions and querying data.
