    Energy Trading System (ETS) enhancements

    As part of the AESO’s ongoing efforts to improve ETS functionality, a number of enhancements will be implemented on April 26, 2017.

    Outage Scheduling start/end time notation

    To increase clarity and consistency, the “Start Time” and “End Time” label in the Outage Scheduling screen will be changed to an Hour Ending notation. There is no change to Outage Scheduling functionality via the user interface or the file upload tool.

    Allow Operating Reserve (OR) substitutions between Sink and Source assets

    Approved Sink and Source assets are now able to substitute OR volumes if permitted under ISO Rule 205.3. To request approval to substitute OR volumes between assets please email

    Change to DDS Submission tab warnings

    To increase clarity and consistency, actions performed in the DDS tab  will now offer warnings in a similar fashion to submissions in the Energy tab.


    For information on using ETS please see the Pool Participant Manuals on the AESO website.

    If you have any questions, please call AESO FirstCall at 1-888-588-AESO(2376) during the business hours of 8 a.m. – 5 p.m. MDT, Monday to Friday, or email
