What action does PJM take when data exchange with a member company is unavailable?

When data exchange with a member company is unavailable, PJM typically utilizes manual dispatch. This approach allows PJM to maintain operational control and ensure system reliability despite the absence of automated data inputs. Manual dispatch involves operators making decisions based on their training, experience, and any available real-time information that may not rely on automated data feeds.

This method is critical in times of communication failures or technical issues because it helps mitigate risks that could compromise the reliability of the power grid. By reverting to manual dispatch, PJM can effectively respond to the situation, make informed operational decisions, and direct generation resources as needed to meet demand while maintaining system stability.

Establishing alternative routing, switching to automated dispatch, or increasing monitoring of affected units might be relevant strategies, but they do not directly address the immediate operational need caused by the unavailability of data. Manual dispatch is the direct and practical approach for managing such situations in a responsive manner.
