Background

Status: Approved
Date Posted: May 24, 2006
Sponsor: Unaccounted For Energy Task Force (UFETF)
Urgent: No
Sections: 13.3
Description: Modify the Settlement Interval Distribution Loss Factor (SILF) to better represent the non-linear relationship between the loss factor and Settlement Interval ERCOT System Load (SIEL).
Reason: The current Distribution Loss Factor (DLF) formula assumes a straight line relationship between DLF and ERCOT system load, which results in mis-estimation of distribution losses in settlement. The proposed formula is non-linear and will better represent distribution losses.
