What is the maximum time allowed for a system to return to IROL after exceeding it?

The maximum time allowed for a system to return to Interconnection Reliability Operating Limit (IROL) after exceeding it is 30 minutes. This time frame is critical for ensuring the reliability of the electric grid. When an IROL is exceeded, it indicates a potential risk to the system, and prompt action is necessary to mitigate any risks to reliability.

Utilities and reliability coordinators are responsible for monitoring the system's operation, and if an IROL is exceeded, they must take immediate steps to restore compliance. The 30-minute limit emphasizes the urgency of the situation and necessitates a swift response to protect the grid from potential disturbances that could lead to larger scale outages or reliability issues. Therefore, this time threshold is established in order to facilitate timely corrective actions.
