    New Security Certificate for Automated Dispatch and Messaging System (ADaMS)

    The current security certificate used to access the ADaMS will expire on November 8, 2021. In order to maintain secure access to ADaMS, a new security certificate will be required.

    Pool Participants who receive dispatches and/or directives from the Alberta Electric System Operator (AESO) system controllers need to request a new security certificate by sending an email to The security certificate will be valid for one year, expiring on September 30, 2022.

    *Please note that due to new industry requirements, the AESO’s certificate provider, Entrust, has advised that the ADaMS digital certificate will require renewal after 1 year and will no longer be valid for 3 years as was the case for the previous certificate. While the new ADaMS digital certificate may state an expiry date of September 30, 2024, the certificate will actually expire September 30, 2022.

    All security certificate requests must be received from the Corporate Contact as registered in the Energy Trading System (ETS). Corporate Contacts as listed in ETS may be viewed by accessing the Pool Participant List on the AESO website.

    It is the corporate contact’s responsibility to ensure the new security certificate is installed on all systems within their organization that require access to the ADaMS by November 8, 2021. Corporate Contacts who request the certificate will receive the certificate by email within three business days.

    Attempts to access the ADaMS using the old security certificates after November 8, 2021, will result in an error message indicating that the site does not exist.
