Project 2009-11 Interpretation IRO-010-1 WECC RCS
Related Files

Status: A request for an interpretation of IRO-010-1, Requirement R1.2 and R3 has been submitted by the WECC Reliability Coordination Subcommittee.  The ballot pool approved the standards revisions.  The revised standards will be submitted to the NERC Board of Trustees for adoption.

The request asks to clarify the following:
  • Does the phrase, “as specified” in Requirement R3 reference the documented data and information specification in IRO-010-1 Requirement R1, or is the data and information in Requirement R3 “any” data and information that the Reliability Coordinator might request?
  • Is the intent of Requirement R3 to have each responsible entity provide its own data and information to its Reliability Coordinator, or is the intent to have responsible entities provide aggregated data (collected and compiled from other entities at the direction of the Reliability Coordinator) to the Reliability Coordinator?
  • Under Requirement R1.2, what actions (on the part of the Reliability Coordinator) are expected to support the “mutually acceptable format” for submission of data and information?
Interpretation Process:
In accordance with the Reliability Standards Development Procedure, the interpretation must be posted for a 30-day pre-ballot review, and then balloted.  There is no public comment period for an interpretation.  Balloting will be conducted following the same method used for balloting standards.  If the interpretation is approved by its ballot pool, then the interpretation will be appended to the standard and will become effective when adopted by the NERC Board of Trustees and approved by the applicable regulatory authorities.  The interpretation will remain appended to the standard until the standard is revised through the normal standards development process.  When the standard is revised, the clarifications provided by the interpretation will be incorporated into the revised standard.
