Entity Registration
WECC Registration actively identifies and registers bulk power system users, owners, and operators responsible for performing reliability functions under mandatory NERC Reliability Standards. We adhere to the Federal Power Act, applicable FERC Orders, and NERC Rules of Procedure (RoP) to ensure comprehensive and accurate registration. Detailed requirements and activities for our Organization Registration and Certification Program are available in RoP Section 500, Appendix 5A, and Appendix 5B of the FERC-approved NERC RoP.

CORES: Use the Centralized Organization Registration ERO System (CORES) for New Entity registration requests or to make changes to existing Registered Entities. For more information, visit NERC’s Centralized Organization Registration ERO System (CORES) Technology Project webpage.
CFR Portal: Use the Coordinated Functional Registration (CFR) Portal for submitting new or updated files. For more information, visit NERC’s Entity Registration CFRs End User Guide.
