Section 7.0 of the Standard Processes Manual (Appendix 3A of the NERC Rules of Procedure) provides the Process for Developing an Interpretation.A valid Request for Interpretation (RFI) is one that seeks additional clarity about one or more Requirements in approved NERC Reliability Standards, but does not request approval as to how to comply with one or more Requirements. A valid Interpretation response provides additional clarity about one or more Requirements, but does not expand on any Requirement and does not explain how to comply with any Requirement. Any entity that is directly and materially affected by the reliability of the North American Bulk Power Systems may request an Interpretation of any Requirement in any continent-wide Reliability Standard. Interpretations will only be provided for Board of Trustees-approved Reliability Standards i.e. (i) the current effective version of a Reliability Standard; or (ii) a version of a Reliability Standard with a future effective date.
The requesting entity can submit an RFI form to the NERC Reliability Standards Staff explaining the clarification required, the specific circumstances surrounding the request, and the impact of not having the Interpretation provided. The NERC Reliability Standards and Legal Staffs will review the request for interpretation to determine whether it meets the requirements for a valid interpretation and will make a recommendation to the Standards Committee (SC) whether to accept the RFI or reject it.
For example, an Interpretation request may be rejected where it:
If the SC rejects the RFI, it shall provide a written explanation for rejecting the Interpretation to the entity requesting the Interpretation within 10 business days of the decision. If the SC accepts the RFI, the NERC Standards Staff shall (i) form a ballot pool and (ii) assemble an Interpretation drafting team with the relevant expertise. Interpretations will be balloted in the same manner as Reliability Standards.
The RFIs that are not accepted by the SC can be found below with the corresponding responses to the Entity that submitted the request.
