United States Mandatory Standards Subject to Enforcement
Section 215 of the Federal Power Act requires the Electric Reliability Organization (ERO) to develop mandatory and enforceable reliability standards, which are subject to Commission review and approval. Commission-approved reliability standards become mandatory and enforceable in the U.S. on a date established in the Orders approving the standards.
 
The standards included on this page are currently enforceable in the United States. A table is appended to the last page of each standard showing the United States effective dates, if applicable. Please also see our US Effective Dates web page to view the applicable dates of each standard by status. 
 
Related information including, but not limited to, the development history, applicable compliance documents, and implementation plans can be found at the related information link to the right of each standard.
 
Please send any questions or comments to sarcomm@nerc.net.
