Attention Users

The ERCOT Market Information System (MIS) provides three levels of information: Public, Secure, and Certified. Public information, including the searchable ERCOT Market Information List (EMIL), is accessible to all. Secure and Certified information can only be accessed through authentication to the MIS with a Digital Certificate.
