*Actual flows within ± 10% of target are acceptable, but not to exceed the actual rating of the path.
**Targets may be altered as anticipated operting conditions become more clearly known. Renewables should be based onindividual entities' Renewable Portfolio Standard.

(Note) Where no target flows are specified actual scheduled transfers should be based on each areas load and generation (deficiency/surplus) balance and economical generation dispatch. The objective of the case should be kept in mind and schedules should be coordinated between areas prior to data submittal.
(1) Only Corrections to the MDF or new data for the MDF need be submitted.
