Coordinate Interchange ― Timing Table 

 Related Files

Status:
The INT-005-3, INT-006-3, and INT-008-3 standards (Permanent Changes to  Coordinate Interchange Timing Tables) were approved by stakeholders with a 100% weighted segment vote.

Purpose/Industry Need:
An Urgent Action SAR to modify the Timing Table in three of the Coordinate Interchange standards (INT-005, INT-006, and INT-008) was approved by its ballot pool on March 30, 2007.  The Urgent Action SAR modified the timing table so that the reliability assessment period for WECC was lengthened from 5 minutes to 10 minutes for e-tags submitted less than 1 hour and greater than 20 minutes prior to ramp start.  Under the Reliability Standards Development Procedure, a change made to a standard with the Urgent Action process is not "permanent" — an urgent action change to a standard expires unless that change is vetted through the full standards development process. 

The new SAR proposes to make the above changes to the timing table permanent, and also proposes to bring the timing table into alignment with the categories (On-time, Late, After-the-fact) used in the latest E-Tag Specification with respect to receipt of an Arranged Interchange.
