NPRR1324  Clarification of the Process to Determine RUC Warmth State

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.
