If PJM's monitoring systems are unavailable for longer than 15 minutes, what may they notify TOs of?

In the context of PJM's operational protocols, if the monitoring systems experience an outage lasting longer than 15 minutes, it is critical that Transmission Owners (TOs) are informed about the operational status of their segments of the bulk power transmission system. This notification serves to maintain oversight and ensure that TOs are fully aware of their responsibilities during the monitoring system's downtime.

Option B indicates that PJM is informing TOs that they are the sole monitor for their sections of the transmission system when the primary monitoring systems are unavailable. This acknowledgment is crucial because it delineates the responsibilities of the TOs during an outage. By designating them as the primary monitor, PJM ensures that TOs remain vigilant and can take necessary actions to maintain system reliability, thereby mitigating risks associated with the lack of centralized monitoring.

Identifying TOs as the sole monitor in such scenarios is essential, as it allows them to act decisively in the absence of automated systems, ensuring the continued integrity and reliability of the transmission network. This reinforces the collaborative efforts between PJM and TOs during critical situations, emphasizing the importance of communication and accountability.
