What is the purpose of CPS-1 compliance evaluation?

The purpose of CPS-1 compliance evaluation is to measure frequency performance. CPS-1, or the Control Performance Standard 1, is a reliability standard established by NERC (North American Electric Reliability Corporation) that focuses specifically on the reliability of the bulk power system by monitoring the system frequency. It evaluates how well a balancing authority maintains the system frequency within the defined limits, responding appropriately to any deviations through adequate control actions.

Maintaining frequency is critical for system stability, as deviations outside the acceptable range can lead to blackouts or equipment damage. By measuring frequency performance, CPS-1 ensures that entities are maintaining a reliable and stable electrical system, thus contributing to the overall health and efficiency of the power grid. This is essential for avoiding reliability issues and enhancing operational integrity across the network.
