If an IROL violation cannot be avoided, what must the RC do?

When an IROL (Interconnection Reliability Operating Limit) violation cannot be avoided, the Reliability Coordinator (RC) must take immediate action to mitigate both the magnitude and duration of the violation. This is contextually important because IROLs represent critical thresholds that, if exceeded, may jeopardize the reliability of the interconnected network. By acting to mitigate the situation, the RC aims to restore the system to a reliable state as quickly as possible.

This approach emphasizes the proactive role of the RC in maintaining system stability. The focus on mitigation reflects a clear understanding that not all situations can be avoided, and therefore, the best course of action is to manage and minimize the impact of the violation effectively. It aligns with the operational protocols that prioritize reliability and speedy resolution of issues that threaten system integrity.

In contrast, other actions, such as establishing a conference call with other Reliability Coordinators or simply initiating control actions after a set time period, while potentially useful in collaboration and broader strategy discussions, do not immediately address the pressing need to resolve an IROL violation. Similarly, contacting affected entities may involve communication, but it doesn't directly engage with the operational mitigation tasks that need urgent attention. The focus on quick mitigation is crucial in times of operational crises.
