US Reliability Standards
  
 
Section 215 of the Federal Power Act requires the Electric Reliability Organization (ERO) to develop mandatory and enforceable Reliability Standards, which are subject to Federal Energy Regulatory Commission (FERC) review and approval. FERC-approved Reliability Standards become mandatory and enforceable in the United States according to the implementation plan associated with the Reliability Standard, as approved by FERC.

 

All Reliability Standards: A one-stop shop that includes links to standards, implementation plans, project pages, Reliability Standards Audit Worksheets, FERC Orders, and compliance guidance.

 

Mandatory Standards Subject to Enforcement: Standards that are currently enforceable in the United States. 

 

Subject to Future Enforcement: Standards that are approved by FERC, but not yet enforceable in the United States.

 

Filed and Pending Regulatory Approval: Standards adopted by the NERC Board of Trustees (Board) and filed with FERC for approval, but not yet approved by FERC.

 

Pending Regulatory Filing: Standards adopted by the Board, but not yet filed with FERC.

 

Inactive:  Standards that have been superseded by another.

 

Pending Inactive: Standards that have been superseded by other standards will never be enforceable. The status will change to inactive at midnight on the day immediately prior to the effective date of the superseding standard.

 

To filter the list of standards, please select a status from the table below. Related information including, but not limited to, the development history, applicable compliance documents, and implementation plans can be found in the reports exported from the table above.

 

Effective Date of the Standard: The date upon which a Reliability Standard goes into effect. On the effective date, the Reliability Standard becomes mandatory and enforceable, and applicable entities are responsible for compliance with the standard’s requirements. 

 

Phased-In Compliance: In some instances, there may be a need to provide entities additional time beyond the standard’s effective date to comply with a particular requirement (or part). In those instances, the implementation plan will provide a “Phased-In Compliance Date” specific to that requirement (or part). The phased-in compliance date represents the later date that entities must begin complying with that particular requirement (or part). Phased-in compliance dates can be found on the U.S. Effective Date Status/Functional Applicability Spreadsheet under the Requirement/Part Effective Date.
