10. Any comments? Enter below:
We did not encounter anything other than the usual data problems on the SCADA/EMS. These problems were resolved using the Pivot method of date comparison. Testing on SCADA/EMS was performed using a completely redundant reserve computer system. Testing extended over many days to allow a complete examination of all subcomponents and repeated year 2000 data/time rollovers.
