What is the required compliance factor for CPS-1?

CPS-1, or the Control Performance Standard 1, is a crucial reliability standard that focuses on ensuring generators maintain adequate control of frequency in interconnected power systems. The standard sets a specific compliance factor that entities must achieve to demonstrate effective frequency control.

The required compliance factor for CPS-1 is set at a threshold of at least 100%. This means that the performance of control systems must meet or exceed this percentage to be considered compliant. Achieving this level indicates that the entity is successfully managing and maintaining frequency within acceptable limits, which is vital for the stability and reliability of the electrical grid.

Meeting this compliance factor is essential not only for regulatory standards but also for maintaining overall system reliability. A CPS-1 value of 100% signifies that the frequency response is adequate and that no significant issues are present in frequency control, contributing positively to the wider grid operations.

The other potential compliance factors do not reflect the requirements set forth in standard CPS-1, making the 100% threshold the correct choice.
