How frequently does the assessment occur during the Performance Assessment Interval?

The assessment during the Performance Assessment Interval occurs every 5 minutes. This frequency is designed to provide a timely and accurate evaluation of performance metrics, allowing for quick adjustments and continuous monitoring. With assessments happening regularly at this interval, it ensures that any fluctuations or changes in performance can be detected and addressed effectively. This is crucial in a transmission system where reliability and efficiency are paramount, as it enables operators to maintain performance standards and quickly respond to any abnormalities that may arise. The other intervals either do not provide enough granularity to capture performance data effectively or would lead to delays in response, which is not ideal in a fast-paced operational environment like transmission management.
