TO Loss Data

Pursuant to FERC Docket No. ER15-197 that was effective on January 1, 2015, each reporting entity or Host Transmission Owner in MISO will update its transmission line loss percentage coincident with its annual Attachment O update and provide that information to MISO. Loss percentages are effective for 12 months.  Entities that have not participated in the MISO market long enough to accumulate 12 months of S105 statements will provide a loss percentage and a methodology to MISO for approval.

Host Transmission Owners and Reporting Entities submit percentages based on whether they use forward looking data or historical data. Loss data for forward looking entities is due by January One of their rate year.  Loss data for historical pricing entities is due by June 30 of their current rate year.
