In the event of an IROL violation, how should the RC act?

The correct choice emphasizes the responsibility of the Reliability Coordinator (RC) to prioritize reliability above all other considerations when faced with an Interconnection Reliability Operating Limit (IROL) violation. The core mission of the RC is to ensure the reliable operation of the bulk power system, which involves maintaining system stability and preventing cascading failures that could result from exceeding established reliability parameters.

In the event of an IROL violation, it's critical for the RC to take necessary actions that safeguard the overall integrity of the power grid, rather than catering to any individual's or entity's interests—whether they be marketing entities, specific companies, or generating companies. The primary goal during such violations is to address the reliability issues effectively, ensuring that power delivery remains stable and that the system continues to function within safe operational limits. This may involve implementing emergency protocols or enacting specific actions to mitigate the violation.

By focusing on the reliability of the overall RC area, the RC fulfills its duty to maintain a secure and dependable electricity supply which ultimately serves all stakeholders in the power sector collectively, rather than prioritizing any single entity or group.
