This optional column is used to alter the demand values seen by the commitment decisions (for day-ahead) compared to the actual dispatched demand (real time).  The column can have positive or negative values and defaults to zero (0).  

The input demand for the zone used for the commitment solve is adjusted as follows:

[Demand Seen By Commitment] = [Actual Demand] * (1+[Forecast Error Factor]) + [Forecast Error Adder].  

NOTE: This column is only used when the Commitment Type = Commitment Optimization.

 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.
