NOTICE DATE:  December 6, 2012

NOTICE TYPE:  M-A120312-09 Outage – Retail/Wholesale

SHORT DESCRIPTION: UPDATE – Restoration of ERCOT systems and postings

INTENDED AUDIENCE:  ERCOT Market Participants

DAYS AFFECTED:  December 3, 2012, to current

LONG DESCRIPTION:  Attached is an updated list of the Enterprise Data Warehouse (EDW) out of compliance postings, which includes the actual and expected dates for each posting. Note that the expected date is the date on which the posting should have occurred under normal processing, not a future date on which ERCOT anticipates the posting to be complete. ERCOT will continue to provide updates on the remaining postings as they are completed.

Note that a correction has been made on the Market Operating Day Extract (MODE) and Consolidated Operating Day Extract (CODE) tab of the attachment. The Day-Ahead Market (DAM) MODE and CODE extracts were posted for Operating Day November 28, 2012, contrary to what was displayed on the previous list. That date has now been changed to November 29, 2012. Reminder that each Real-Time Market (RTM) MODE and CODE extract includes Operating Days for the Initial, Final and True-up Settlements. None of the missed MODE and CODE extracts have been posted yet.

ADDITIONAL INFORMATION:  Settlement Dispute due dates will need to be re-set as a result of the data necessary for shadow Settlements. ERCOT will post new dates and will provide details in a Market Notice when the necessary data has been posted.

The following system is still unavailable:

· Market Operations Test Environment (MOTE)
