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

2.1Background

The Participating Transmission Owner (PTO) Percent percent Revenue revenue Prepre-calculation calculates the percentage revenue allocation for each PTO for use in the calculation of several related Charge Codes.

2.2Description

Any Scheduling Point or Take-Out Point whose capacity ownership or Entitlement is held by a single PTO obtains all High Voltage Wheeling Revenue To to PTO (CC 384) and Low Voltage Wheeling Revenue revenue to PTO (CC 385) collected at a Scheduling Point or Take-Out Point disbursed to such PTO. For Scheduling Points where multiple PTO’s hold an ownership or Entitlement, then High Voltage Wheeling Access Charges To to PTO (CC 384) are first allocated between relevant TAC Areas in proportion to the ownership and Entitlements at the Scheduling Point. These revenues are then further disbursed amongst the PTO’s within each TAC Area in proportion to their Transmission Revenue Requirements.

Percent PTO Allocations allocations are calculated as daily percentages for each Scheduling Point and Take-Out Point with the understanding that FERC -related readjustments to a PTO’s TRR changes or revisions or new submittals related to the PTO’s originally submitted ownership or Entitlement occur infrequently. These adjustments can occur at any time and triggers a calculation of Percent percent PTO Allocationallocation.

This Charge Code will be implemented pursuant to a configuration enhancement procedure that allows for gains in performance, thereby reducing the volume of calculations executed during the monthly Settlement Run. The outcome of this feature is not published on the monthly Settlements Statements issued to participants. However, this enhancement procedure has no impact on the actual calculation of the settlement amounts determined by this Charge code. The performance enhancement is achieved through the availability of a feature that makes the results of (previously calculated) daily Settlement Runs available during to the CAISO operator for the monthly run in lieu of the operator having to re-execute daily calculations within the monthly Settlement Run. Additionally, this feature will provide the CAISO operator monthly totals of (previously calculated) daily outputs as well as monthly totals of primary bill determinants as needed. The CAISO will notify participants of which Charge Code uses this feature by including this statement in the description of the affected Charge Codes. In addition, the CAISO will indicate in the applicable CAISO Formula sections which of the individual calculations within the monthly run utilize this feature.Participants can verify the Settlement Amounts resulting from this Charge Code in their monthly calculations by utilizing the daily input data as defined in the input sections of each Charge Code, the amounts and/or quantities of which are published on the relevant, daily Settlement Statements.

3.6CAISO Formula

3.6.1The ISO formula for PTO Percent percent Revenue revenue Allocation allocation by PTO ID P, Intertie ID Q, Resource resource Type type t is as follows:

3.6.1.1PTOMonthPercentRevenueAllocationQPmd=PTOPercentRevenueAllocationQPmd

Note: PTOPercentRevenueAllocationQPmdis an output from custom view that returns the daily percentage value that was calculated for the last Trading Day of the applicable Trading Month.

3.6.1.1BAandPTOIDSwapDayIntertieRevenueAllocationPercentage BQmd = ATTRIBUTESWAP (PTOPercentRevenueAllocation QPmd)

Note: The interval positions for BA_ID and PTO_ID will utilize the ATTRIBUTESWAP function in order to provide PTO’s with intertie allocation percentages at interties that they have entitlement to. This charge type is derived for reporting purposes only

3.6.1.2CAISOTotalDayPercentageIntertieAllocationPercentage Qmd = PTOPercentRevenueAllocation QPmd

96 / PTOPercentRevenueAllocationDuplicate2QPmd / PTO Percent percent Revenue revenue Allocationallocation for Interties by PTO ID P, Intertie ID Q, Trading Monthm, and Trading Day d
For Interties designated as high voltage where ownership or Entitlement is held by multiple PTOs who do not share the same TAC Area, revenue is first allocated by TAC Area based on total ownership or capacity Entitlement. Revenue is then further allocated within that TAC Area based on a PTO’s (with ownership or Entitlement) TRR percentage versus all other PTOs’ with ownership or Entitlement total TRR within that specific TAC Area.
All low voltage Interties have ownership or Entitlement held by no more than 1 PTO. Output percentage is set to 1 by default.
Else, for high voltage Interties where ownership or Entitlement is held by no more than one PTO, or, if ownership or Entitlement is held by multiple PTOs within the same TAC Area,, allocation percentage is based on a PTO’s (with ownership or Entitlement) TRR percentage versus all other PTOs’ with ownership or Entitlement total TRR
Developmental Note: MultiOwnedIntertiesWherePTOShareDifferentTACAreasFlag Q will only be derived at high voltage interties where ownership or Entitlement is held by multiple PTO’s who do not share the same TAC Area. In calculations within this charge type where MultiOwnedIntertiesWherePTOShareDifferentTACAreasFlag Q is evaluated, absence of this flag at all other interties will mathematically evaluate out to ‘equals zero’
7 / PTOPercentRevenueAllocationDuplicate1 QPmd / PTO percent revenue allocation for Take -Out Points by PTO ID P, Intertie ID Q, Trading Month m, and Trading Day d
