NOTICE DATE: July 6, 2012

NOTICE TYPE:  R-A070612-01 – Extracts

SHORT DESCRIPTION:  TDSP ESIID Extract – AMS Indicator Defect

INTENDED AUDIENCE:  CRs and TDSPs

DAYS AFFECTED:  June 12, 2012; June 18, 2012; June 25, 2012; July 2, 2012; July 3, 2012

LONG DESCRIPTION: Texas Set 4.0 changes included the addition of the TDSP_AMS_INDICATOR column to account for the AMSR and AMSM values. ERCOT has identified a defect which allows the value of R to be populated in this column as well. 

Rows with the R value should indicate premises where AMS meter existed but has been removed. ERCOT will update the code to prohibit the R values from populating in the TDSP ESIID Extract in a future release.

Until the change is implemented, market participants should treat the value of R in the TDSP_AMS_INDICATOR column as a null value.
