NPRR478 Extension of DAM QSE Offer and Bid Submission Deadline Due to ERCOT Systems Delays
ReasonThe 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.
