Who must the Transmission Operator inform when an SOL has been exceeded?

• A. Its Balancing Authority.
• B. Its Supervisor.
• C. Neighboring Transmission Operators.
• D. Its Reliability Coordinator.

Answer: (D)

When a Transmission Operator exceeds a System Operating Limit (SOL), it has a responsibility to inform its Reliability Coordinator. The Reliability Coordinator plays a crucial role in ensuring the reliable operation of the grid and is responsible for monitoring the overall reliability of the system across multiple operators and balancing authorities. By notifying the Reliability Coordinator of the exceeded SOL, the Transmission Operator enables the coordinator to analyze the situation, assist in mitigating any potential issues, and ensure that appropriate actions are undertaken to maintain system reliability. This communication is essential in preventing cascading failures and ensuring that all operators within the interconnected system are aware of critical conditions that might affect their operations and reliability. The Reliability Coordinator acts as a central point of contact that facilitates coordination among various entities during times of operational stress.
