Wyoming and Pawnee in northeastern Colorado.
Definition: WCI crosses TOT3 (WECC Path 36).
Transfer Limit: The WCI Phase1 Comprehensive Progress Report (Phase 1 Report) indicates
that WCI will add up to 900 MW of capacity across TOT3. WCI has been
accepted into Phase 2 of the Path Rating Process with a Planned Rating of
900 MW.
Critical
Disturbance
that limits the

capability:
Phase I studies indicate that the limiting condition will be overloading the
