Today’s LiveWire Spotlight looks at two re-organized NERC Standards governing the derivation and communication of System Operating Limits (SOLs). Although FAC-011-4 and FAC-014-3 align with the related IRO and TOP standards that take effect on 4/1/17, the proposed updates extensively change the existing SOL Methodology.

The informal drafts of the two System Operating Limit standards have been posted on the NERC website for a 30-day review period. Comments must be returned to the project team by August 12, 2016
