    Enhancement to Dispatch Down Service (DDS) Submissions - Energy Trading System (ETS)

    As part of the AESO’s on-going efforts to improve the user experience for participants, a change to the Dispatch Down Service (DDS) Submission section will be implemented to the Energy Trading System (ETS) effective Nov. 27, 2019.

    A reason field will be added to the DDS Submission section in ETS allowing participants to add an acceptable operational reason for each individual hour ending in their DDS submissions and restatements.

    File Upload: Please note that effective Nov. 27, 2019, participants submitting DDS submissions and restatements via File Upload will need to ensure that the files submitted to ETS include this new field.  A revised template and example has been added to our website at Market > Energy Trading System tools > File upload examples and templates.

    The DDS Submission section in ETS is available to participants who have received a digital certificate to access applicable asset information.
