Status:
The NERC Board of Trustees adopted the proposed amendments to the Rules establishing the BES Exception process on January 18, 2012. The project was filed with the Commission on January 25, 2012 and approved December 20, 2012.
Purpose/Industry Need:
On November 18, 2010, the Federal Energy Regulatory Commission (“FERC” or the “Commission”) issued an Order directing NERC to revise the definition of Bulk Electric System and address the Commission’s concerns as identified in Order No. 693, issued on March 16, 2007. The definition encompasses all Elements necessary for the reliable operation and planning of the interconnected transmission network. A draft definition, developed by the Project 2010-17 standards drafting team, was posted for a 30-day comment period on April 28, 2011.
Concurrent with the development of the revised Bulk Electric System definition, a Bulk Electric System Rules of Procedure Team (“BES ROP Team”) was formed to develop a procedure for processing exceptions to the Bulk Electric System definition. The BES ROP team has developed a second draft of the proposed Appendix 5C Bulk Electric System Component Exception Procedure, which is being posted along with several related documents for comment for 45 days. Concurrently with the posting of the proposed Appendix 5C, NERC is also posting for a 45-day comment period and initial ballot the BES Technical Principles for BES Exceptions document (posted through October 10, 2011).
