Today’s LiveWire Spotlight is on the second draft of Appendix 5C of NERC’s Rules of Procedure, which was developed to allow case-by-case challenges to the extent of the Bulk Electric System as defined in the NERC Glossary. It was mandated by FERC to ease the impact of Order 743 requiring the extent of the BES to be clearly defined to include most facilities operated at 100 kV and above.

The updated drafts of the BES definition exception process and its supporting documentation have been posted by the project team for a 45 day review. Comments may be returned to the Rules of Procedure drafting team until 10/27/11
