To comply with BAL-001 requirements, a Balancing Authority must achieve which performance metrics?

To comply with BAL-001 requirements, a Balancing Authority must focus on maintaining its performance metrics to ensure reliability in the electric grid. The correct choice highlights that CPS1 (Control Performance Standard 1) is required to be greater than or equal to 100%. This indicates that the Balancing Authority is effectively managing its control area and maintaining its net load and generation balance within prescribed limits.

Furthermore, the requirement that the Area Control Error (ACE) does not exceed the Balancing Authority Area Limit (BAAL) is crucial since it reflects the Balancing Authority's success in controlling imbalances between generation and load. Maintaining ACE within BAAL ensures that the system is stable and minimizes the risk of frequency disturbances.

This combination of CPS1 being at least 100% and ACE remaining within limits is critical to achieving operational reliability and adherence to NERC standards, emphasizing the importance of effective monitoring and control practices in maintaining a reliable electricity supply.
