How quickly must a PJM Member notify the control room about an equipment loss of ≥ 100 kV?

The requirement for a PJM Member to notify the control room immediately about an equipment loss of ≥ 100 kV is grounded in the critical need for safety, reliability, and operational integrity within the power grid. When high-voltage equipment experiences a failure, it can have significant implications for system stability, potentially impacting not just the immediate area but also surrounding networks. Prompt notification allows for rapid assessment and response, enabling grid operators to implement necessary measures to mitigate the risk of outages or cascading failures.

In high-voltage situations, time is of the essence. Any delays in communication can hinder the ability of grid operators to make informed decisions, allocate resources effectively, or activate contingency plans to manage the situation. Immediate reporting ensures that the control room is aware of all significant changes to grid conditions, allowing for an adjusted operational response to maintain system reliability.

The other timeframes such as 30 minutes, 60 minutes, or by the end of the day would potentially compromise the response capabilities during critical situations where every minute counts in preventing larger systemic issues. Therefore, immediate notification is essential to uphold the standards and responsibilities of PJM Members in maintaining a reliable electric power system.
