Background

Status:	Rejected
Date Posted:	Dec 6, 2012
Sponsor:	GDF Suez Marketing NA
Urgent:	No
Sections:	6.3, 6.5.7.3, 6.5.9.4.2, 6.6.12 (new), 6.6.12.1 (new), 6.6.12.2 (new)
Description:	This Nodal Protocol Revision Request (NPRR) will administratively set Locational Marginal Prices (LMPs) at the System-Wide Offer Cap (SWCAP) during Security-Constrained Economic Dispatch (SCED) executions in which ERCOT has deployed Emergency Response Service (ERS) Resources and/or Responsive Reserve (RRS) Service supplied by Load Resources.
Reason:	Currently during SCED executions in which ERCOT has deployed ERS Resources and/or RRS supplied by Load Resources, the deployments could create a price reversal. Real-Time prices are vital to sending the correct signals to both Generation Resources and loads on when to react in a manner that ensures ERCOT System reliability. Price reversals send the incorrect signal during these vital intervals and this NPRR is designed to mitigate these price reversals.
