Status:
NERC has completed a review of the comments received from 56 individuals or groups and has revised the Data Request with the assistance of the System Analysis & Modeling, and System Protection and Control Subcommittees. The subcommittees provided extensive help in addressing stakeholder concerns are evident in the revisions made to the Data Request.

The second draft of the Data Request is now posted for a 45-day comment period beginning on Friday, May 11, 2012 and ending on Monday, June 25, 2012.

Summary:
Order 754 is the Final Rule approving the interpretation of Interpretation TPL-002-0a PacifiCorp (Project 2009-14) regarding requirement R1.3.10. In addition to the approval, the Commission expressed a concern about single point of failure of protection systems and issued a directive for further investigation. From the Order, “…the Commission believes that there is an issue concerning the study of the non-operation of non-redundant primary protection systems; e.g., the study of a single point of failure on protection systems” (P19). In the first part of the directive (P20), the Commission directed FERC staff to meet with NERC and its appropriate subject matter experts to explore this reliability concern, including where it can best be addressed, and identify any additional actions necessary to address the matter. This portion of the directive was satisfied by the October 24-25, 2011 Technical Conference. In the second part (P20), NERC must complete an informational filing within six months of the Order (middle March 2012) explaining whether there is a further system protection issue that needs to be addressed and, if so, what forum and process should be used to address that issue and what priority it should be accorded relative to other reliability initiatives planned by NERC.

Purpose/Industry Need:
The participants in the technical conference perceived a reliability concern regarding the comprehensive assessment of potential protection system failures by registered entities. The group agreed on the need to study if a gap exists regarding the study and resolution of a single point of failure on protection systems. Note: This is not a “redundancy of protection systems” issue. The issue is, do the requirements in the transmission planning reliability standards adequately address the analysis and discovery of a protection system failure in order develop plans to meet the performance requirements for the BES (i.e. TPL-001, 002, 003, and 004).
