Background

Status: Approved
Date Posted: Aug 21, 2012
Sponsor: Calpine
Urgent: No
Sections: 4.5.1
Description: This Nodal Protocol Revision Request (NPRR) extends the submission deadline for Qualified Scheduling Entities’ (QSEs’) bids and offers in the Day-Ahead Market (DAM) subsequent to a system-wide delay caused by a failure of ERCOT’s market applications.
Reason: The current 1000 deadline for ERCOT to begin DAM execution can leave little or no time for QSE personnel to submit bids and offers when the DAM submission period is interrupted by delays, failures or outages in ERCOT’s market applications. The financial risk of missing the deadline with bids and/or offers, leaving a party fully exposed to Real-Time volatility, is not an acceptable outcome when the proximate cause was a failure of ERCOT’s systems to process transactions timely. This NPRR simply seeks to allow for as much time in the extension of the DAM submission timeline as is initially lost due to ERCOT’s system failures or delays. This provision would only be invoked by ERCOT if the failure affects the entire market and would not be invoked when the delay or failure is isolated to a Market Participants’ systems.
