2. Introduction 2.1 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 components calculated for the particular time period over which the allocation is performed: The overall metered CAISO Demand plus Real-Time Interchange export schedules 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 referenced in the prior item. 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 Demand quantity is calculated. The five Pre-calculations differ by the composition of the Loads and exports that are included in their Measured Demand outputs. The Measured Demand Pre- calculation configurations, the Load and export composition of their outputs, and the associated output frequency (5-minute, 10-minute, hourly, etc.) are identified in the table titled “Measured Demand Pre-calculation Configurations” in the Background section of the Pre-calculation Measured Demand over Control Area Configuration Guide document. Some of the Measured Demand Pre-calculation configurations recognize exemptions to the calculation for various Business Associates and resources. In some instances a Measured Demand configuration may produce multiple outputs, each one recognizing a particular exemption or set of exemptions. For each Measured Demand output calculation, its exemptions are determined and defined by the requirements of the allocations in which the Measured Demand Pre-calculation output is employed.

2.2 Description Some of the Measured Demand Pre-calculation configurations identified in the table of Measured Demand Pre-calculations referenced in the prior section require a net MSS Measured Demand quantity or a net MSS Demand quantity. Net MSS Demand (in MWh as a negative value) is calculated as the lesser of zero (0) or the sum of Meter Data for Demand (in MWh as a negative value) of all Participating Loads and Demand from other Resources (e.g., NGR) internal to the MSS plus the Meter Data representing the Generation (in MWh as a positive value) of all MSS Generating Units. Net MSS Demand does not include the Energy of Real-Time Interchange schedules. Net MSS Measured Demand (in MWh as a negative value), on the other hand, is defined to be the lesser of zero (0) or Net MSS Demand, to which lesser value is added the sum of the Energy (in MWh as a negative value) for all Real-Time Interchange export schedules. To satisfy the varying requirements of different Measured Demand Pre-calculations, the CG PC MSS Netting calculates Net MSS Measured Demand or net MSS Demand quantities in various output configurations.

Reflecting the difference in the requirements for each output based on transmission components and output frequency, the CG PC MSS Netting offers seven several different net Measured Demand outputs (with one of the outputs actually representing a net MSS Demand quantity due to its omission of export Energy). The outputs differ in their representation of net Measured Demand based on the inclusion or exclusion of in- state Real-Time Interchange exports, net exports and contractual Transmission Losses. Each output from the CG PC MSS Netting is resolved to a particular combination of three (3) levels – the MSS entity, the Business Associate scheduling Energy for the MSS entity, and the output frequency. Net MSS Measured Demand quantities are output in multiple frequencies – 10-minute and hourly, The outputs are generated for the successor Measured Demand Pre-calculations, where a net MSS Measured Demand or MSS Demand value at a specific frequency is required in the calculation of a Measured Demand output.
