NOTICE DATE:  January 11, 2012

NOTICE TYPE:  W-B102711-02 Settlements


INTENDED AUDIENCE:  QSE settlement personnel

DAYS AFFECTED:  December 1, 2011 – January 5, 2012

LONG DESCRIPTION:  The SHORTSCEDFLAG implemented as of December 1, 2011, in the Base Point Deviation Settlement was erroneously set up as a ‘Private’ bill determinant in ERCOT Systems; thus, the SHORTSCEDFLAG bill determinant was not being provided in the Settlement extracts. ERCOT changed the bill determinant classification on January 3, 2012, and is reflagging the data for extract output in order to provide historical flags to the market. The historical data went out in the Market Input Header/Interval data sets in the below listed extracts.
