Which entities are required to conduct and document an annual test of its Operating Plan?

• A. Reliability Coordinator only
• B. Balancing Authority only
• C. Transmission Operator only
• D. Reliability Coordinator, Balancing Authority, and Transmission Operator

Answer: (D)

The essential idea is that the Operating Plan is a coordinated, cross-party procedure that involves the Reliability Coordinator, the Balancing Authority, and the Transmission Operator. Each of these entities has a distinct role in how the bulk electric system is managed: the Reliability Coordinator oversees regional coordination and system security, the Balancing Authority manages real-time resource sufficiency within its area, and the Transmission Operator executes the planned actions on the transmission system. Because emergencies and abnormal operating conditions require synchronized actions and precise communication among all three, the standard requires that each entity not only maintains its own Operating Plan but also conducts and documents an annual test of that plan. The test verifies that procedures are current, that necessary data exchanges and communications channels work, and that personnel know their roles and can execute the plan effectively. If testing were limited to just one entity, gaps in coordination with the others could undermine reliability during real events, so the requirement applies to all three together.
