I am not aware of any offsite guidance to use virtual mode for other than
short duration troubleshooting. Turbine 9 was in virtual mode for approximately 40 hours. This will have the appearance of improperly manipulating availability so that it is higher than it should be. The owner would argue that the turbine should have been left faulted offline or the repair switch thrown. System Performance Group will see if we can assess how prevelent this was at Mill Run when there were no gaps in 10 minute data. It is possible that this virtual mode use was rare or of little practical effect. I am not going to mention this to anyone outside of Systems Performance Group & Joe Thorpe until we know how prevelent it was.

This was not corrected until the crews were instructed to put the turnine into repair mode to perform the repairs. This has been addressed and all personnel understand the repercussions. If there are any other questions please let me know.
