Today’s LiveWire Spotlight is the first of two articles on the definitions and standards governing the derivation and communication of System Operating Limits (SOLs).  Today’s issue addresses the three proposed updates to the NERC Glossary and the standards they will affect.  Part II (scheduled for November 2) will look at the initial drafts of four FAC standards that will fundamentally change how Operations and Planning limits are established, distributed, and aligned.

The initial versions of the definitions of System Operating Limit and SOL Exceedance have been posted on the NERC website for a 30-day review period.  Comments must be returned to the project team by October 30, 2017.
