What is the compliance evaluation period for the CPS-1 factor?

The compliance evaluation period for the CPS-1 (Control Performance Standard 1) factor is indeed 12 months. This standard is part of the NERC Reliability Standards and is focused on assessing the performance of Balancing Authorities in maintaining control of the area balance.

During this 12-month evaluation period, Balancing Authorities must demonstrate their ability to manage their resources effectively to avoid significant imbalances. The metric focuses on ensuring that the balancing authority operates within defined limits regarding frequency deviation, which is vital for maintaining the reliability of the power grid.

Understanding the 12-month period is essential for entities involved in compliance as it drives their operational planning, resource allocation, and overall management strategies to meet reliability standards.
