NOTICE TYPE: M-A101220-01 General

SHORT DESCRIPTION: ERCOT to release the redesigned Market Information System (MIS) to the Production Environment

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: November 11, 2020

LONG DESCRIPTION:  ERCOT is releasing the redesigned Market Information System (MIS) to the Production Environment on November 11, 2020. Market Participants (MPs) should begin using the new MIS to access data and applications. The new MIS URL is https://mis.ercot.com/public/.  

All users may access public data on this site. However, digital certificates are required to access applications, secure data, and certified data. Existing digital certificates and roles will work on the new MIS site; there is no need to request new certificates. Additionally, users should use the new URL for any integrations used to programmatically access data from the MIS.

The current ERCOT Market Information List (EMIL) web interface is now integrated with the new MIS site. The standalone EMIL web interface will be decommissioned on November 11, 2020.

Enhancements have been made that allow for the new MIS site to be viewed in both the Chrome and the Internet Explorer browser.

ACTION REQUIRED: MPs should use the new site exclusively beginning November 11, 2020. The current MIS will be decommissioned in January 2021. Bookmarks should be changed to the new site and any to the current MIS should be removed. The new URLs are: https://mis.ercot.com/public for the public site and https://mis.ercot.com/secure for the authenticated site. All users should use the integrated EMIL on the new site and remove the existing bookmarks to https://mis.ercot.com/emil.
