NOTICE TYPE:  M-A122208-02 REMINDER:  Release - Retail

SHORT DESCRIPTION:  ERCOT has an on-cycle Retail Release planned for 12:00 PM Saturday, January 24, 2009 through 12:00 AM Monday, January 26, 2009.

INTENDED AUDIENCE:  All Market Participants        

DAY AFFECTED:  12:00 PM Saturday, January 24, 2009 through 12:00 AM Monday, January 26, 2009.

LONG DESCRIPTION:  ERCOT has an on-cycle Retail Release scheduled from 12:00 PM Saturday, January 24, 2009 through 12:00 AM Monday, January 26, 2009.  For reference, four Market impacting SIRs, three non-Market impacting SIRs, and one non-Market impacting project are included in the attachment.

ERCOT will also use the normal MarkeTrak maintenance window beginning 7:00 PM Friday, January 23, 2009 through 12:00 AM Monday, January 26, 2009 to implement PR-70007_01 - MarkeTrak Enhancements, Release 4.  MarkeTrak service availability is 7:00 AM to 7:00 PM during retail business days.

ERCOT will implement SIR 12140 to enhance the Customer Registration Database with a change from Active Directory (AD) to Lightweight Directory Access Protocol (LDAP). This is to resolve the Market Participant Dispute function, which currently is not operating properly. ERCOT has had a workaround in place, and this enhancement will be a permanent solution.
