Re: [EnergyPlus_Support] Electricity Error

["Michael J. Witte" <mjwitte@xxxxxxxx>]

This could mean the chiller is not operating at all during those months, or it 
could be a mistake in the reporting inputs.  First, turn on report variable 
"Chiller Evap Heat Trans Rate" to confirm if the chiller is operating.  If the 
chiller is operating, then check the reporting inputs and make sure there is 
not a schedule attached to the electiricity variable which may be supressing 
reporting during these months.   If the chiller is not running, check if there 
is a demand on the chilled water loop, "Plant Loop Cooling Demand".  Once you 
determine what is operating and what is not, you should be able to find which 
controls or schedules need fixing.
