NOTICE DATE: October 27, 2011
NOTICE TYPE: W-B102711-01 Settlements
SHORT DESCRIPTION: New ERCOT wide exemption Flag – SHORTSCEDFLAG
INTENDED AUDIENCE: QSE settlement personnel
DAY AFFECTED: December 1, 2011
LONG DESCRIPTION: The SHORTSCEDFLAG will be used by the Settlement system to indicate if the 15-minute Settlement Interval contains
a SCED interval less than four (4) minutes in duration. The Settlement Interval will have a value set to (1) one for each Settlement Interval containing a SCED interval less than (4) four minutes. The change will take effect on the Initial Settlement of Operating
Day December 1, 2011.
ADDITIONAL INFORMATION:
Currently, ERCOT implements this exemption by manually
setting the FQDEVFLAG to a value of three (3)
in the 15-minute Settlement Interval containing the SCED interval less than four (4) minutes in duration. With the implementation of the SHORTSCEDFLAG, ERCOT will cease performing this manual
process. The new SHORTSCEDFLAG does not impact the overall structure of the extracts or tables nor result in an updated DDL.
