NOTICE DATE: December 14, 2023

NOTICE TYPE: M-A112123-02 General

SHORT DESCRIPTION: ERCOT to launch beta version of new Public API

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: December 15, 2023

LONG DESCRIPTION: On December 15, ERCOT will launch a beta version of its new Public API application. The application will be open to Market Participants as well as the public.

This initial Public API will consist of three components.

  1. A Data Access Portal ( for users to browse expired data by selecting from an existing list of provided data reports.
  2. An API Explorer ( for developers to learn specifications on how to use the APIs.
  3. An API Gateway (, the actual tool that allows applications to call the APIs. 

The Data Access Portal will provide public users and Market Participants faster access to expired ERCOT public data through a web portal and directly through the use of APIs. Users will be able to extract and browse the latest data, as well as expired data, from certain public ERCOT reports. Initially, 35 reports will be available within the beta version of the Data Access Portal, with the number of reports increasing 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).

The API Explorer will provide Market Participant developers with a RESTful framework based on OpenAPI standards, allowing developers to build their own applications using ERCOT reports.

Access to and use of these websites is covered by the legal information provided on the ERCOT Terms of Use (TOU) page. Users must accept the TOU in order to use the sites.

ADDITIONAL INFORMATION: ERCOT encourages users to offer feedback for improving the portals. Please send feedback about these new portals at any time via the ERCOT Public Portal or to your Account Manager. A previous notice was sent on November 21.
