This optional column  is used to limit the operation of a plant each year. When the record has a non-negative value, Aurora will limit the unit's operation to the entered number of  hours in the year.

The limit is not optimized across the year but applied chronologically so that as soon as the unit reaches its limit, it is turned off for the rest of the year. 

 NOTE: If the FUEL reference is specified for this variable the value in the Fuel Table will be applied.

 NOTE: Inputs can be specified for any time period (annual, monthly, weekly, hourly or sub-hourly). For information on how to specify a time series for a variable, see Entering a Time Series.
