The Planning Committee last week endorsed changes to Manual 14B: PJM Region Transmission Planning Process to improve the procedure for analyzing and addressing short circuits.

Reason for Change: PJM currently analyzes short circuit cases for the current year +1 and +5. System modifications are difficult for transmission owners to implement with a one-year lead time.

Impact: The annual Regional Transmission Expansion Plan will analyze short circuit base cases for the current year +2.
