If a Sink Balancing Authority is potentially facing load shedding due to an interchange curtailment, whom should they notify?

The responsibility of a Sink Balancing Authority during an interchange curtailment, especially in the face of potential load shedding, involves promptly notifying the appropriate entities to ensure system reliability and stability. In this context, notifying Reliability Coordinator X is crucial because Reliability Coordinators are tasked with overseeing the reliable operation of the interconnected transmission system. They have the authority and responsibility to monitor real-time grid conditions and manage any potential reliability issues that may arise.

Informing Reliability Coordinator X allows for a coordinated response to manage the situation effectively. This notification ensures that all relevant parties are aware of the potential load shedding scenario and can take the necessary steps to mitigate impacts, including exploring options for supporting the system or adjusting generation and demand as needed.

Reliability Coordinator Y, the System Operator, and the Federal Energy Regulatory Commission also play important roles in grid management and regulation, but in this specific scenario focusing on the notification to address looming load shedding due to an interchange curtailment, Reliability Coordinator X is the appropriate contact. They are the key entity responsible for ensuring that timely and coordinated actions are implemented across the balancing authorities to maintain reliability.
