What functional entity was established to provide a "big picture" view of the system?

The Reliability Coordinator is responsible for providing a comprehensive overview of the bulk electric system's reliability. This role involves coordinating planning and real-time operations among various entities, which allows for enhanced awareness of system conditions, demonstrates interconnections, and supports the reliable delivery of electricity.

The Reliability Coordinator monitors the state of the system, assesses potential risks, and implements measures to maintain system stability. This "big picture" perspective is crucial for ensuring that all operational decisions contribute to the overall reliability and integrity of the power grid. Additionally, the Reliability Coordinator works closely with other entities to improve situational awareness and ensures that all parties have the necessary information to make informed decisions regarding their operations.

In contrast, the roles of System Operator, Transmission Operator, and Generator Operator are more focused on specific aspects of system management, rather than providing a holistic overview. System Operators typically focus on real-time control, Transmission Operators oversee the flow of electricity within transmission systems, and Generator Operators manage the generation resources. While all these roles are essential for maintaining system reliability, it is the Reliability Coordinator that primarily focuses on the broader system perspective.
