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 proposed updates to the NERC Glossary terms “System Operating Limit” and “System Voltage Limit” and the standards they will affect.

The Glossary updates and the impacted standards have been posted on the NERC website for a 45-day review and concurrent ballot. Comments must be returned to the project team and votes cast by October 10, 2018.
