The Markets and Reliability Committee approved the following manual changes Thursday.
Manual 1: Control Center and Data Exchange Requirements
Reason for change: New rules for access to PJM Energy Management System (EMS).
Impacts:
- Added new section 2.5.7 detailing rules for transmission owner read-only access to PJM’s EMS. No screen scraping is allowed;
- Modified section 3.2.3 to clarify procedures for data communication outages;
- Modified section 4.2.4 to clarify repeating of All Call messages;
- Adds details to Information Access Matrix in Attachment A.
Manual 12: Balancing Operations
Reason for change: PJM is changing the regulation requirement to align it with operational needs and address volatility in light load periods.
Impacts:
- Changes On-peak (05:00-23:59) requirement to 700 effective MW, a decrease in the requirement for 52% of days, an increase for 48% of days. Net daily decrease of about 60 MW (section 4.4.3).
- Changes Off-peak (00:00-04:59) requirement to 525 effective MW, an increase for 66% of days and a decrease for 34% of days. Net daily increase of about 20 MW (section 4.4.3).
- Changes regulation scoring methods:
- Performance scoring for small regulation allocation: Historical performance scores will be used if the control signal has an average absolute value less than 1% of the regulation assignment (section 4.5.6);
- Performance scores when data is not available: Historical performance scores will be used if data is not available and for intervals less than 15 contiguous minutes (adds section 4.5.9);
- Regulation Assignments: Scoring will be suspended for 10 minutes after assignment to allow time to ramp into position (adds section 4.5.10).

Manual 19: Load Forecasting and Analysis.
Reason for changes: Integration of East Kentucky Power Cooperative (EKPC), addition of annual demand resources and need to ensure accuracy of load shed programs.
Impacts:
- Adds EKPC to load forecast model;
- Revises assumption for winter load management;
- Makes minor typo fixes and clarifications for NERC audits;
- Changes demand resources available in winter months due to addition of annual DR product;
- Codifies guidelines for switch operability studies for load management programs. The guidelines are designed to ensure the accuracy of load shed estimates for participants in direct load control programs. The study must be designed for a minimum 90% confidence level and based on a randomly selected sample from the entire population of participating customers. No customers can be excluded.

Manual 20: PJM Resource Adequacy Analysis
Reason for change: Codifying procedure approved by FERC. The changes were endorsed by the Planning Committee in October 2012.
Impact: Revises section 5 to add Test 2 for the six-hour duration requirement for the Limited DR Product. The Test 2 procedure is effective with the 2016/17 Delivery Year.
