For certain Critical Infrastructure Protection (CIP) requirements, a registered entity may request a Technical Feasibility Exception (TFE) where strict compliance with the requirement cannot be achieved. Procedures for requesting, modifying, or terminating a TFE, as well as the associated data requirements, are defined in Appendix 4D of the Rules of Procedure (Procedure for Requesting and Receiving Technical Feasibility Exceptions to NERC Critical Infrastructure Protection Standards). TFEs are currently managed through Align for all registered entities.
If you have questions regarding TFEs, please contact: [email protected].
