    AESO API – New Data

    Effective July 22, 2021, AESO system marginal price data will be available via secure Application Programming Interface (API). APIs allow AESO data to be accessed programmatically, providing for more reliability, and eliminating the need to ‘screen scrape’ our reports and webpages.

    Please note, the AESO has also made the following changes to the existing APIs:

    • For the existing Pool Price report data API, the field names have been revised to be more consistent with normal API nomenclature.
    • The APIs in the left bar menu of the API page have been reorganized.

    Instructions to access the AESO’s API page can be found 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
