NOTICE TYPE:  M-A020410-01 Extracts

SHORT DESCRIPTION:  Extract file names may have been affected by data cleanup

INTENDED AUDIENCE:  All ERCOT Market Participants

DAY AFFECTED:  February 3, 2010

LONG DESCRIPTION:  On Wednesday, February 3, 2010, as part of a data cleanup prior to Nodal Market implementation, ERCOT changed the folder names for Market Participants in the Texas Market Link (TML) to align with the currently registered names. For some Market Participants this may have resulted in a change in the name of one component of their downloaded extract file names. Extract file data is not affected by this change.

ADDITIONAL INFORMATION:  The file naming convention for extract files is as follows:

Rpt<Entity Name><Extract Name><Date Time of Extract><Extract Type>.<File Type>

The only component that changed was the Entity Name, which was changed to align with the current registered name of the Market Participant in the registration system.
