Today’s LiveWire Spotlight is on NERC’s Interim report on one type of High Impact Low Frequency threat to the bulk power system from rare, but intense solar flares.

NERC’s Electric Sector Coordinating Council has approved the Task Force’s recommendations. A geomagnetic disturbance project will be added to the Standards Development program – with a priority yet to be determined.
