Introduction Background In the allocation of various payment and charges, the amounts are divided among Business Associates (BAs) in proportion to their relative contribution to the overall Measured Demand quantity (in MWh) over which the allocation is performed. Thus, an allocation of payment or charges requires the following two Measured Demand calculations that are conducted for the particular time period over which the allocation is performed: the overall metered CAISO Demand plus Real-Time Interchange export schedules, excluding that portion of Demand of Non-Generator Resources dispatched as Regulation through Regulation Energy Management, in the grid sector or area over which the allocated payments and charges apply and the contribution of each Business Associate to the overall CAISO Demand plus Real-Time Interchange export schedules, excluding that portion of Demand of Non-Generator Resources dispatched as Regulation through Regulation Energy Management. To provide the Measured Demand quantities that are used in multiple charge code calculations that allocate various payments or charges, the CAISO implements a set of Pre-calculation processes, referred to as Measured Demand Pre-calculations, to calculate particular Measured Demand quantities. There are five (5) Measured Demand Pre-calculation configurations in which an overall Measured D
