A Capacity Emergency Warning is specifically designed to notify system personnel about critical conditions related to the available capacity within the PJM (Pennsylvania-New Jersey-Maryland) Regional Transmission Organization's system. This alert is essential during times of high demand or low supply scenarios, highlighting potential shortages in generation capacity. Understanding the need for such alerts is crucial for effective grid management, as they enable timely responses to prevent overload and maintain system reliability. By alerting personnel to the risk of capacity issues, operations can be adjusted to safeguard the reliability of the electricity supply, ensuring that demand does not exceed what the system can provide. The other types of alerts may serve different purposes but do not focus specifically on capacity issues. They may address operational considerations, stability problems, or general notifications but lack the explicit directive of managing capacity emergencies.
