Registration in the U.S.

NERC developed a Statement of Compliance Registry Criteria, detailed in Appendix 5B of the NERC Rules of Procedure, that delineates the selection criteria employed by NERC and the Regional Entities to determine fairly and consistently which organizations should be registered as users, owners and operators of the bulk power system and therefore should be included on the NERC Compliance Registry (NCR). A full list of registered entities can be found in the NCR.

The ERO Registration Procedure was developed to help new entities who are candidates for registration with NERC understand key terminology, how the registration process works, and initial requirements for registered entities, NERC, and the Regional Entities. The ERO Enterprise also has an Informational Package that provides a framework to assist you with becoming a NERC registered entity, including the steps to complete shortly after the registration process has been completed.

NERC’s Centralized Organization Registration ERO System (CORES) system is used to register new entities and allows those companies to manage their registration information and functional relationships. To use CORES, you must register for an ERO Portal account. CORES and ERO Portal User Guides are available on the NERC website. Entities registering as a Transmission Owner or Generator Owner will also need to complete the MRO Facility Verification Form. The facility verification form includes both the inventory of assets as well as the functional relationships between the facilities, owners, operators and planners. This allows MRO to validate the functional relationships identified in Section 501.1.4 of the NERC Rules of Procedure.
