NOTICE DATE:  September 2, 2011
NOTICE TYPE:  W-B090211-01 Operations
SHORT DESCRIPTION:  Phase 2 validation rejection defect in the ERCOT Market Management System for Energy Bids, Energy Only Offers, and PTP Obligation Bids
INTENDED AUDIENCE:  ERCOT QSEs and CRRAHs
DAY AFFECTED:  September 2, 2011
LONG DESCRIPTION:  ERCOT has identified a defect in the pre-Day Ahead Market (DAM) transaction rejection process, Phase 2 validation that occurs at 07:00 CPT, for Energy Bids, Energy Only Offers, and Point to Point (PTP) Obligation Bids as part of the software implementation changes on August 23, 2011 with NPRR323, Correct DAM Credit Exposure Language and Enable Qualified Expiring CRRs to Offset PTP Bid Exposure.
Previously, if there was not enough QSE credit to support an entire bid or offer, the entire bid or offer was rejected.  Currently, if there is only enough credit to support some hours of the bid or offer, those hours are retained and the remaining hours are rejected within the bid or offer.  This behavior will be corrected in a future release and only applies to the Phase 2 validation process.  All DAM credit behavior between 07:00-10:00 CPT remains unaffected.
