Background

Status: Approved
Date Posted: Feb 24, 2026
Sponsor: ERCOT
Urgent: No
Sections: 5.6.2
Description: This Nodal Protocol Revision Request (NPRR) clarifies the process currently used by ERCOT to determine the startup warmth state (i.e., hot, intermediate, or cold) of a block of contiguous Reliability Unit Commitment (RUC)-Committed Hours. Since December 2010, ERCOT has determined the startup warmth state of a block of contiguous RUC-Committed Hours by counting the time between the start of the first RUC hour in a block of startup-eligible RUC-Committed Hours to the most recent time the Resource went Off-Line prior to the first RUC-Committed Hour of the block. This NPRR is submitted for transparency to codify that practice into the Protocols.
Reason: General system and/or process improvement(s)
