ERCOT to Decommission Old MIS Portlet Site

ERCOT has announced it will decommission its old Market Information System (MIS) Portlet site on Wednesday, February 10, 2021, making it no longer available to market participants.

Upgraded with more features, the new MIS site has been made available to the public since Wednesday, November 11, 2020 where users can access their data and applications easier. The platform allows for EMIL export and searches for notices, reports, extracts, and applications posted by ERCOT. While there is no need to request new digital certificates (as the existing digital certificates will continue to work), authentication using digital certificates is still required to access applications and secure data.

Adapt2 will continue to keep clients up-to-date with market updates. More information about changes related to ERCOT's Market Information System (MIS) Portal site may be found here. If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via email at
