Calculation of Contributing Load and Contributing Flow. The Nodal Load for a load bus with a positive nodal distribution factor is a contributing Load, defined as CLoad, and the Nodal Flow for that Load is contributing flow, defined as CFlow. To identify contributing Loads that have a material impact on the Generator Deactivation Reliability Need, the ISO will calculate a contributing materiality threshold, defined as CMT, as follows: Where m is for the total number of Subzones and n is for the total number of load buses in a given Subzone.
