Today’s LiveWire Spotlight is on FERC Order 773 accepting the updated definition of the Bulk Electric System, implementation plan, and case-by-case exception process developed in Phase I of Project 2010-17. Although mostly supportive, the Commission has ordered two modifications to mitigate specific operating circumstances which may introduce risk to the BES.

The updated Definition of the Bulk Electric System takes effect on April 1, 2013 in the US. Clients who have facilities newly identified as part of the BES will have 24 months beyond that date to fully comply with all applicable Reliability Standards.
