Data requests
The AESO provides real-time and historical data on the wholesale electricity price, supply and demand, transmission and generation outages, ancillary services and operating reserves and other resources for market participants. Click here to access current and historical market data and reports.
Market participants and other stakeholders can request access to certain data not currently posted online or posted in a different format.
To make a request, please download and submit the data request form to manalysis@aeso.ca.
Note some data requests may not be processed due to commercially sensitive reasons (as detailed in ISO rule 103.1). The AESO will contact you if this is the case and provide an opportunity to amend your data request accordingly.
One of the AESO’s duties is to make data available to market participants in a manner consistent with the fair, efficient and openly competitive (“FEOC”) operation of the market. This includes the provision of data that is timely, accurate, disseminated fairly, appropriately comprehensive and equally accessible by all market participants. As a result, certain data requests may be published on this page should they be deemed of commercial value and not of a confidential nature (see past data requests below).
Turnaround time is generally 10-15 business days (from approval). A charge of $100/hour applies to all data requests and final estimates would depend on the complexity of the request. The following table provides approximate cost estimates on frequently-requested data.
