Digital Certificates
Background ERCOT’s digital certificate vendor has migrated public root certification to 2048-bit, which in
turn requires all MP’s to utilize 2048-bit certificates. Digital certificates are required to access, download, submit, and query ERCOT systems.
• Timeline and required action
– No later than Sept 30th, Market Participants must update their certificates to 2048-bit• Market Operations Test Environment (MOTE) has been configured for testing • MP technical staff can follow 5 steps in the ERCOT SSL Communications Standards
– After Oct 1st, all 1024-bit certs should be deleted from keystore, as they will no longer be of use
– ERCOT will send market notices and brief numerous market participant forums

Browser Standard Timeline
ERCOT currently supports Internet Explorer 6 and 7 browsers Other browsers are mostly, if not fully, compatible though not supported by ERCOT IT staff
(Firefox, Safari, Chrome, etc) ERCOT is planning to have all market facing applications compatible with Microsoft browser
IE8 (Internet Explorer v8) by April 1, 2012 The IE8 browser comes with the latest version of Microsoft Windows Operating
Systems (Windows 7) and contains improved security features. Prior to April 1st, 2012 ERCOT will publish a list of recommended IE8 browser
configuration settings
• ERCOT’s support for IE8 will allow Market Participants to upgrade their browsers anytime after the effective date
– Any Market Participant that has a problem with IE8 after April 1, 2012, can report the issue to Client Services or to ERCOT’s Helpdesk
– ERCOT will continue to support Microsoft IE7 until mid-2014. No action is required from Market Participants at this time.
