What action is taken when the IROL limit has been exceeded for 5 minutes or longer?

When the IROL (Interconnection Reliability Operating Limit) limit has been exceeded for 5 minutes or longer, it is crucial to maintain grid reliability and ensure that appropriate actions are taken to prevent further issues.

In this context, initiating a PJM All-call is a standard procedure that involves notifying all relevant parties in the PJM Interconnection about the situation. This action ensures that everyone who might be affected or who has responsibilities in managing the grid is informed and can coordinate to mitigate any risks. Timely communication is essential in the operation of the grid, as it allows stakeholders to react quickly and effectively to the reliability threats posed by exceeding the IROL limits.

This coordinated approach is vital in operating environments where immediate action may be required to stabilize the system, reroute power, or implement other reliability measures, thus ensuring the continued safe and reliable operation of the power grid.
