PJM will operate without violating which voltage rating on a continuous basis?

The continuous operation of PJM must adhere to the normal voltage rating. This rating represents the expected voltage levels that are necessary for safe and efficient operation of the electrical grid. Operating within the normal range ensures that all equipment functions properly and minimizes the risk of failures that could arise from voltage fluctuations.

The normal voltage rating is essential for maintaining system stability, ensuring that demand can be met without causing damage to infrastructure or affecting the reliability of power supply. Adhering to this rating supports overall grid reliability and performance, fostering an environment where all connected systems can operate optimally.

Other voltage ratings, like emergency, failure, or overvoltage, represent conditions that are not suitable for continuous operation and may indicate abnormal situations or stress to the system. Thus, maintaining operations within the normal voltage rating is crucial for the long-term functionality and resilience of the electricity transmission network.
