What is NERC's primary concern with communications systems?

NERC's primary concern with communications systems is reliability. This focus ensures that the communications infrastructure can consistently support the reliable operation of the electricity grid. Reliable communications are critical for monitoring, control, and coordination among various entities within the power system, including generation, transmission, and distribution operations.

A reliable communication system allows for accurate data sharing, timely decision-making, and effective response to emergent issues, thereby helping to prevent outages and maintain system stability. Without this reliability, the risks of miscommunication or delayed information can lead to serious consequences, including grid failure or safety hazards.

While elements such as cost efficiency, speed of data transfer, and scalability are also important considerations, they are secondary to the fundamental requirement of reliability. NERC prioritizes the ability of communication systems to function correctly and consistently under all conditions, which directly impacts the overall security and stability of the electric grid.
