Non Commit Penalty
Column Type = Percent
This column is used to provide further refinement and flexibility in the modeling of fixed non-commit penalties. When the value specified in this column is non-zero, Aurora will use this penalty instead of the global Fixed non-commit penalty on the Commitment folder of Simulation Options.
This option allows the user to specify the penalty or increment (input as a percent) to be applied to the dispatch cost of a commitment type unit when it has not committed for operation. This option applies only to those units with an nonzero value in the Non Cycling column of the Resources Table.
By default, the global option is set to 2900 percent (a 30 times penalty) so that commitment units will be seen as too expensive to operate if not originally committed.
NOTE: The Use econ non-commitment penalty option must NOT be selected for the fixed non-commit penalty to be applied to resources using unit commitment. The fixed non-commit penalty is always used for pool commitment resources. If the value is 0 or NULL, or the column does not exist, the global Min back down penalty form Dispatch and Demand will be used.
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.
