According to NERC, the purpose of this new standard is to “maintain the coordination of protection systems installed to detect and isolate faults,” and it requires utilities to establish a number of procedures.

This new standard directly affects transmission, generation, and distribution entities, and it puts a heavy burden on utilities as it requires a vast amount of time and resources of the settings engineers.

In order to comply with this new standard, utilities must meet the following three requirements:

  1. Create an established process for relay setting development.
  2. Perform a protection system coordination study every six years (or compare the present fault current to an established baseline and perform the study when the system comparison deviates by greater than 15%).
  3. Develop new and revised protection system settings for the bulk electric system by following the first requirement.


Utilities have 24 months to comply after the FERC final ruling. The final ruling will be 60 days after June 7.
