This optional column works in conjunction with the Demand Requirement column and is used to specify the demand source. By default it references a comma delimited list of Zone IDs. Alternatively, a list of demand collection IDs can be referenced by prefixing the list with dc_ (e.g. dc_ERCOTHouston, ERCOTSouth, ERCOTNorth). The two methods cannot be mixed.
Aurora will resolve the demand for the current hour from the list of zones or demand collections and then apply the multiplier from the Demand Requirement column to get the ancillary requirement.
