The Ancillary Min Contribution column is used to specify the minimum contribution, in MW, that a given resource is required to  make towards the ancillary products in which it participates.  If this field is NULL/blank, the default value used is zero.

When the resource participates in more than one ancillary product, the entry should be a comma-delimited list with the same products entered in the same order as in the Ancillary Services input column for that resource.  If an entry is found for at least one product but not for all products in which the unit participates, the entry for the last product specified will be used for all unspecified products.

 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.
