1. Purpose of Document
The purpose of this document is to capture the requirements and design specification for a SaMC Charge Code in one document.
2. Introduction
2.1 Background
Grid Management Charge Codes are monthly charges assessed to participating Scheduling Coordinators for the purpose of recovering all of the CAISO’s administrative and operating costs. These costs include, but are not limited to, startup, development, financing, and the costs of ongoing operation and maintenance associated with the CAISO’s Control Area operator responsibilities. Grid Management Charges also include costs associated with administering the scheduling, bidding, dispatch, and settlement of all Energy and Ancillary Services.
GMC rates are calculated as set forth in Section 11 of the CAISO Tariff. The formula rate methodology provides Market Participants with the financial security of predictable GMC pricing while ensuring that the CAISO is able to recover its actual costs in a timely manner. The charges are shown as a monthly charge on the Settlements Statements for the last day of each month, with billable quantities being published on daily statements where applicable. GMC charges are one-sided and do not offset with any other charge code for neutrality.
The Energy and Transmission Charge Codes are designed to recover costs associated with the scalable portion of Grid Reliability Services, and is a function of the intensity of use of the transmission system within the Control Area. Scalability implies an increasing relationship with flows, outages and disturbances within the Control Area. The costs of managing the Control Area will be higher to the extent that total flows increase. They will also be higher to the extent that entities cause inadvertent flow that must be managed in Real time.
2.2 Description
Charge Code 4505 is calculated as the monthly metered CAISO Demand plus Export schedules, which represents total flows on the transmission grid. The Energy and Transmission Services Net Energy is based on the sum of the metered CAISO Demand and Export schedules for a Scheduling Coordinator in a given Trading Hour, for a Trading Day, of Trading Month. Metered CAISO Demand is the actual metered value for a Scheduling Coordinator’s Load resources. Export schedules are calculated as the sum of all the Deemed Delivered Energy Quantity for specific export schedules.
3. Charge Code Requirements
3.1 Business Rules
Bus Req ID / Business Rule1.0 / All calculation levels, including relevant Billable Quantities and the final Settlement Amount, shall be calculated on a daily basis and output on daily Settlement Statements where input Bill Determinants allow.
2.0 / For adjustments to the Charge Code that cannot be accomplished by correction of upstream data inputs/recalculation or operator override Pass Through Bill Charge logic will be applied.
4.0 / Settlements system shall be able to identify specific registered resources as exempted resources from this charge code.
5.0 / Charge Code 4503 output feeds the Export Quantity portion of CC 4505 billable quantity calculations, so exemptions are the same as CC 4503 but are already included.
5.1 / The Load Quantity portion of CC 4505 billable quantity calculation is being fed by the Measured Demand Over Control Area Pre-Calculation output, BAHourlyTotalGrossMeteredCAISODemandQuantity_GMC_MDOverCA, which already incorporates exemptions.

Row # / Variable Name / Description1 / GMCEnergyTransmissionServicesNetEnergyRate / FERC approved GMC rate from settlements standing data based on applicable start and end dates.
2 / PTBChargeAdjustmentGMCEnergyTransmissionServicesNetEnergySettlementAmount BJmd / PTB adjustment variable for this charge code, amount per SC. ($)
3 / TORExceptionFlag B / Flag indicating TOR exception from Charge Code, where exception is represented by “1”.

Row # / Variable Name / Predecessor Charge Code/Pre-calc Configuration
1 / BAHourlyTotalGrossMeteredCAISODemandQuantity_GMC_MDOverCA Bmdh / Measured Demand Over Control Area Pre-Calculation
2 / GMCCoreReliabilityServicesExportQuantity Bmd / CC 4503 GMC - Core Reliability Services Export Energy
3 / BASettlementIntervalResourceFinalBalancedContractCRNQuantity BrtNz’hi / PC ETC, TOR and CVR Quantity
3.6 CAISO Formula
3.6.1.1 IF TORExceptionFlag B = 1
THEN
GMCEnergyTransmissionServicesNetEnergySettlementAmount Bmd = 0
ELSE
GMCEnergyTransmissionServicesNetEnergySettlementAmount Bmd = GMCEnergyTransmissionServicesNetEnergyMeteredDemandQuantity Bmd * GMCEnergyTransmissionServicesNetEnergyRate
3.6.1.2 Where
GMCEnergyTransmissionServicesNetEnergyMeteredDemandQuantity Bmd = HourlyEnergyTransmissionServicesLoadQuantity Bmd + GMCCoreReliabilityServicesExportQuantity Bmd
3.6.1.2.1 Where
HourlyEnergyTransmissionServicesLoadQuantity Bmd = ABS (
(BAHourlyTotalGrossMeteredCAISODemandQuantity_GMC_MDOverCA Bmdh - BAHourlyBalancedTORLoadQuantity Bmdh))
3.6.1.2.2 Where Resource type (t) = ‘Load’ and Contract Type = ‘TOR’
BAHourlyBalancedTORLoadQuantity Bmdh = BASettlementIntervalResourceFinalBalancedContractCRNQuantity BrtNz’hi
3.6.1.3 Where
GMCEnergyTransmissionServicesNetEnergyRate is the current FERC approved rate for the CAISO Control Area
3.7 Outputs
Output Req ID / Name / DescriptionIn addition to any outputs listed below, all inputs shall be included as outputs.
1 / GMCEnergyTransmissionServicesNetEnergySettlementAmount Bmd / The total amount charged to a Business Associate B for Energy and Transmission Services for Net Energy in a Trading Day d,of Trading Month m.
2 / GMCEnergyTransmissionServicesNetEnergyMeteredDemandQuantity Bmd / The total metered Demand quantity for a Business Associate B, in a Trading Day d,of Trading Month m.
3 / HourlyEnergyTransmissionServicesLoadQuantity Bmd / The total hourly-metered load quantity for a Scheduling Coordinator, excluding exemptions.
4 / BAHourlyBalancedTORLoadQuantity Bmdh / The Total Balanced TOR Load Quantity for Business Associate B for Trade Month m, of Trade Day d, and Trade Hour h
