The Markets and Reliability Committee last week endorsed the following manual changes:

Manual 3: Transmission Operations

Reason for changes: Update.

Impact: Adds language regarding approval of emergency rating changes; added applicability for individual generators greater than 20 MVA; clarified reference to voltage coordination; revised outdated references.

Manual 10: Pre-Scheduling Operations

Reason for changes: Annual review.

Impact: Minor updates for clarity; added references to forecasted planned outages and reporting outages on synchronous condensers.

Manual 14B: PJM Region Transmission Planning Process

Reason for changes: Improve the procedure for analyzing and addressing short circuits.

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

Manual 14D: Generator Operational Requirements

Reason for changes: Changes made at RFC request, and for consistency.

Impact: Includes changes to reactive capability testing; replaces outdated references; requires generators operating or scheduled for PJM to operate to notify PJM prior to attempting a restart following a trip or failure to start.
