If a PJM member's EMS becomes unavailable, what do some members do?

When a PJM member's Energy Management System (EMS) becomes unavailable, moving dispatchers to a backup control center is a practical and essential step to ensure continued operations. This approach allows for the seamless management of electricity transmission and generation even when primary systems are down. Backup control centers are typically equipped with the necessary infrastructure and technology to monitor grid operations and make real-time decisions to maintain system reliability.

This strategy is critical in the energy sector, where operational continuity is essential to prevent outages and maintain service. It ensures that the organizations can still respond effectively to grid conditions or emergencies, utilizing trained personnel who can operate from a designated alternate location. This process minimizes risks associated with system unavailability and supports overall grid resilience.

In contrast, shifting to a new software platform or contacting PJM for instructions may not provide immediate solutions during the critical time of EMS failure, as these actions could lead to further delays. Shutting down operations temporarily would be detrimental and not a feasible option, as it could lead to significant disruptions in service and reliability obligations.
