Background

Status: Approved
Date Posted: Sep 23, 2010
Sponsor: ERCOT
Urgent: No
Sections: 4.2.3, 6.5.7.1.13
Description: This Nodal Protocol Revision Request (NPRR) moves the requirement to post Shift Factor data from the Day-Ahead Operations section (Section 4.2.3) of the Nodal Protocols as a daily posting to the Real-Time operations section (Section 6.5.7.1.13) as an hourly posting.
Reason: Initially ERCOT planned to design the Shift Factor report data to come from the Day-Ahead Market (DAM) or Day-Ahead Reliability Unit Commitment (DRUC) in order to make the data manageable. Recently it was found that an hourly data pull from the Real-Time Energy Management System (EMS) is feasible and more desirable since the data will more accurately reflect Real-Time operational constraints.
