Today’s LiveWire Spotlight is the second of two articles on the definitions and standards governing the derivation and communication of System Operating Limits.  Part I was issued on October 19 and addressed the proposed updates to the NERC Glossary that describes an SOL and how they are applied.  Today’s issue looks at the initial drafts of four FAC standards that will fundamentally change how Operations and Planning limits are created, distributed, and aligned.

The initial drafts of the System Operating Limit standards have been posted on the NERC website for a 45-day review period and concurrent ballot.  Comments must be returned and votes cast by November 13, 2017.
