Overview of Entity Registration Process

To determine the function(s) for which an entity is applicable and should be registered, please refer to the NERC website and the Appendix 5B Statement of Compliance Registry Criteria, which is found on the NERC Rules of Procedure page.

All requests for new or revised NERC registrations should be submitted to ReliabilityFirst through the Centralized Organization Registration ERO System (CORES) tool. ReliabilityFirst Registration staff will review each request and respond accordingly.

Once an entity’s request for registration is approved by ReliabilityFirst and NERC, the Primary Compliance Contact (PCC) will receive a NERC notification letter of listing on the “NERC Compliance Registry (NCR).” The PCC is responsible for assigning any needed ERO Portal access permissions to other entity users that registered for ERO Portal accounts. Registered entities are responsible for maintaining and updating all contact information in the ERO Portal/CORES.
