February 2, 2008 ARC Event

Saturday February 2, 2008 from 10:00 EST through 10:20 EST the Midwest ISO invoked the ARC procedure due to a 500 MW Net Schedule Interchange obligation and actual load coming in higher than forecasted load. Up to 70 percent of the available ARC operating reserves were utilized during this period to correct the imbalance. There were no ARS events initiated during the event.
