If a Balancing Authority does not comply with the Control Performance Standard, what services are they not permitted to provide to other Balancing Authority entities?

The correct choice centers on the role of a Balancing Authority in maintaining the reliability of the power system. When a Balancing Authority does not comply with the Control Performance Standard, it indicates a failure to effectively balance supply and demand within its area. As a result, they must refrain from providing regulation related to control performance to other Balancing Authorities.

Control Performance Standards are set to ensure that Balancing Authorities manage their resources effectively to maintain the reliability of the grid. If a Balancing Authority is failing to meet these standards, engaging in or providing regulatory services related to control performance could exacerbate system imbalances and lead to operational issues.

Thus, they are restricted from providing these services until they are in compliance with the standards, ensuring the overall stability and reliability of the interconnections remain intact. This emphasizes the importance of adherence to performance standards for the benefit of the entire electric grid, rather than just the individual Balancing Authority.
