    AESO API – New Data

    Effective November 30, 2021, the following data is now available via secure Application Programming Interface (API):

    • Energy Merit Order Report data
    • Operating Reserve Offer Control Report data
    • Actual Forecast Report data

    APIs allow AESO data to be accessed programmatically, providing for more reliability, and eliminating the need to ‘screen scrape’ our reports and webpages.

    Instructions to access the AESO’s API page can be found on the AESO website here. Additional APIs containing other public data currently available in ETS, ADaMS, and other sources will continue to be added in the future. 

    If you have any questions regarding this enhancement, please email us at

    We welcome your feedback! Please share any feedback or suggestions you may have about the new API with us at
