*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.

"Chelan PUD is a strong supporter of ColumbiaGrid and the work that’s accomplished through the transmission Planning and Expansion Functional Agreement (PEFA). As a result of that process, the mid-C utilities (Chelan, Grant and Douglas PUDs) and Bonneville Power Administration were able to reach an agreement that defined the need for a new transmission line, as well as determine who will construct, own and pay for the facility. Those difficult decisions were made successful through the expert and independent expertise of the ColumbiaGrid staff."
