This optional column is used to represent an hourly premium (or discount) factor applied to the Value of the unit (Total Revenues – Total Costs).  This column is typically used with the Value Adder column.

For example, if the original Value was 100, the Value Adder was $10/hr in nominal terms, and the Value Factor was 0.3, then the reported value would be = [Original Value]*(1 + [Value Factor]) + [Value Adder] = 100*1.3 + 10 = 140.

 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.
