About the ERCOT Data Access Portal

The Data Access Portal provides public users and Market Participants access to expired ERCOT public data though a web portal and directly, through the use of APIs. Users can browse recent data, as well as expired data, from certain public ERCOT reports. Initially, 35 reports are available in the Data Access Portal, with the number of reports scheduled to increase with time. 

To locate public data that is not included in the Data Access Portal, please continue to search the ERCOT Market Information List (EMIL).

Users may submit a data request via the Public Portal to request public historic reports no longer available on the website.

Release Notes

    • The beta vision of the Data Access Portal included only 35 public reports. 
    • All data from the 35 reports is available via API. 
    • Users must read and accept the Terms of Use  for the site. Once the terms are accepted, users must register to use the API Explorer by providing their name and email address.
