NERC UFLS Standard Development Original Approach • NERC UFLS SDT submitted performance criteria for industry comment on July 2 through August 15, 2008. • NERC UFLS SDT originally contemplated a simple continent-wide umbrella of performance characteristics supplemented with more detailed regional standards. • A subsequent meeting in late July with FERC staff required the NERC UFLS SDT to rethink approach.
