INTENDED AUDIENCE:  CRs and TDSPs

DAY AFFECTED:  Wednesday, February 18, 2009 from 5:30 AM to 8:30 AM

LONG DESCRIPTION:  On Wednesday February 18, 2009 from 5:30 AM to 8:30 AM, ERCOT experienced an internal system processing issue resulting in 18  files not processing.

The affected 867 transactions were not processed into ERCOT’s Settlement system and forwarding transactions were not sent to the appropriate Market Participants. The breakdown by transaction type is as follows:

Transaction Type	Count
814_01	52
814_04	32

Reprocessing of the affected transactions was completed today.  The reprocessed 867 files will attempt to load into the settlement system batch process tomorrow morning (Saturday, February 21, 2009).

 

The root cause was ERCOT’s Electronic Data Interchange (EDI) application experiencing a degradation in which processes were running long because of locks on the database.  Additional details will be provided in the monthly ERCOT IT Incident Market Notice Summary.
