    Automated Dispatch and Messaging System ("ADaMS") Notice

    The AESO will be implementing a change to how dispatch instructions are sent out through ADaMS, effective July 3, 2019.

    This change will impact all current hour dispatch instructions. The dispatch effective time will now be top-of-the-current-minute plus 2 minutes. Top-of-the-hour advance dispatch instructions will be unchanged and communicated as they currently are. Pool participants are still subject to acknowledge dispatch instructions within 2 minutes as per Section 201.7 - Dispatches, of the ISO rules.

    Contingency Reserve directive instructions will not be impacted by the change.

    Performance assessments for operating reserve dispatches will continue to be measured according to the requirements outlined in Division 205 - Ancillary Services Market, of the ISO rules.

    The frequency of notifications received from the Advance Dispatch Notification Functionality in DVN may be impacted by the above change to dispatch instructions. Market participants may want to adjust their parameters for the Advance Dispatch Warning Tolerance on the effective date of this change.
