The Planning Committee Thursday approved changes to Manual 19: Load Forecasting and Analysis. The changes go next to the Markets and Reliability Committee.

Reason for changes: Integration of East Kentucky Power Cooperative (EKPC), addition of annual demand resources; and need to ensure accuracy of load shed programs.

Impact:

• 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; and
• 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.
