Within 30 calendar days, the Generator Owner must provide tap settings and impedance data to which recipients?

• A. Associated Transmission Operator and Transmission Planner
• B. Reliability Coordinator
• C. Balancing Authority
• D. Adjacent Transmission Operators

Answer: (A)

Accurate network modeling and protection coordination depend on having up-to-date tap settings and impedance data for equipment connected to the grid. The Generator Owner must provide this information within 30 calendar days to the two parties that directly rely on it: the Associated Transmission Operator, who runs the transmission system that the generator interconnects with, and the Transmission Planner, who uses the data to build and update the system model for planning studies. The Associated Transmission Operator needs the data for real-time operation, protection schemes, and outage coordination, while the Transmission Planner uses it to ensure planning analyses reflect the true interconnection. While Reliability Coordinators, Balancing Authorities, and Adjacent Transmission Operators may interact with these data in other contexts, the 30-day requirement is specifically directed to the associated operator and the transmission planner.
