Submissions and reports

This page details the contents of STEM & Bilateral related reports for the new Wholesale Electricity Market. The Market Participant Interface (MPI) offers reports through web pages. Notifications are displayed in the Market Messages display when new report information is available for download (for a limited selection of reports). Each report can be retrieved as a CSV or an XML file download from the associated MPI display.

 Reports are available via web services, where Market Participants can send a request which is delivered using the standard web service protocol SOAP (Simple Object Access Protocol). Existing local certificates can be used with current endpoints until the New WEM Commencement Date (NWCD) of the 1st October 2023. With the integration of APIM, DigiCert certificates will need to be requested from the WA Energy Market Management team (wa.operations@aemo.com.au), and used in conjunction with new APIM endpoints.
