NOTICE DATE: October 7, 2022

NOTICE TYPE: M-D090922-03 General

SHORT DESCRIPTION: Reminder - Decommissioning Legacy URLs for Public Reports

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: October 10, 2022

LONG DESCRIPTION: ERCOT will decommission the legacy URLs of Public reports on October 10, 2022. This action does not remove access to any reports on or the ERCOT Market Information System (MIS). This is simply a clean-up of legacy URLs as part of a larger effort to enhance the security of ERCOT websites. Market Participants were notified of this upcoming change through discussion in the ERCOT Technology Working Group (TWG). New URLs to Public reports were created at the time of the website redesign in November 2021. Now, ERCOT is simply removing the unnecessary legacy URLs.

Attached, please find a spreadsheet with all URLs that will be decommissioned. The spreadsheet includes the name of each Public report, the report URL to be decommissioned, and the new report URL.

ACTION REQUIRED: If you are still accessing ERCOT Public reports using these legacy URLs, you will need to switch to accessing the same information at the updated URLs.

Here are examples of legacy URLs that will no longer be active after October 10, 2022.

Here are examples of the updated URLs already in use that have replaced the legacy URLs to Public reports.

Note: The Xs in the URLs indicate where a Report Type ID or EMIL ID would be inserted.

To search for an ERCOT Public report, please visit and click the Market Participants navigation item and then EMIL. The ERCOT Market Information List (EMIL) allows you to search for any data product or report by Product Name, Product Description, EMIL ID, Report Type ID, or applicable Rules.

ADDITIONAL INFORMATION: Please review the ERCOT website for previous Market Notices related to this subject.
