Purpose of Document

The purpose of this document is to capture the requirements and design specification for a Charge Code in one document.

Introduction

1 Background

The CAISO shall invoice all Scheduling Coordinators (SCs) for legitimate Transferred Frequency Response (TFR) costs that are invoiced to the CAISO by an external Balancing Authority Area entity (the TFR provider). Each SC shall be obligated to pay the CAISO all of the Transferred Frequency Response Charges it is invoiced by the CAISO in accordance with the applicable provisions of the CAISO tariff. Each SC’s responsibility for Transferred Frequency Response Charges is based on its calculated NERC/WECC Metered Demand.

2 Description

The CC 7597 Transferred Frequency Response charge configuration will calculate the allocation amount to Scheduling Coordinators, based on their NERC/WECC metered demand. The CAISO will perform the calculations necessary to implement the business rules identified in the Business Rules section below. Additional processing rules associated with the settlement and invoicing for the Transferred Frequency Response charge are defined in the main body of the BPM for Settlement & Billing.

For the purpose of Settlements implementation, the Transferred Frequency Response charge shall be reflected in an initial settlement statement, while a recalculation settlement statement shall reflect changes required to correct an invoice for typographical or other ministerial error. The Transferred Frequency Response charge settlement statements shall be separate from other market settlement statement types.

The Transferred Frequency Response charges (either from an initial statement or recalculation statement) shall be invoiced using the Frequency Response invoice type that is separate from the Market invoice type and NERC/WECC type.

Charge Code Requirements

1 Business Rules

|Bus Req ID |Business Rule |

| |The CC 7597 Transferred Frequency Response charge code is calculated at an annual frequency. |

| |Transferred Frequency Response charges are charges for all legitimate costs invoiced to the CAISO by a |

| |Balancing Authority under a contract for Transferred Frequency Response. (Fact) |

| |The CAISO will issue the Transferred Frequency Response charge-related statements and invoices separate from |

| |other market settlement statement and invoice types. |

| |For the purpose of Settlements implementation, the Transferred Frequency Response charge shall be reflected in |

| |an initial settlement statement, while a recalculation settlement statement shall reflect changes required to |

| |correct an invoice for typographical or other ministerial error. |

| |The Transferred Frequency Response charge statement date will be the first trade date of the assessment year. |

| |The Transferred Frequency Response charge assessment year is defined as a calendar year about two years prior |

| |to the compliance year for which Frequency Response insurance is procured from a TFR provider. |

| |For example, for NERC/WECC compliance year from December 1, 2016 to November 30, 2017, for which CAISO procures|

| |insurance for frequency response, the compliance year would be considered as year 2017 and so the TFR charge |

| |assessment year is the calendar year two years prior, which is calendar year 2015. |

| |The Transferred Frequency Response charge (either from an initial statement or recalculation statement) shall |

| |be invoiced using the Transferred Frequency Response invoice type that is separate from the Market invoice type|

| |and NERC/WECC type. |

| |The separate Transferred Frequency Response invoice will reflect a single day bill period which encompasses the|

| |first trade date of the assessment year. |

| |The CAISO shall invoice Scheduling Coordinators for all of the charges that are invoiced to the CAISO by the |

| |Transferred Frequency Response provider. |

| |Each Scheduling Coordinator shall be obligated to pay the CAISO all of the Transferred Frequency Response |

| |charges it is invoiced by the CAISO. (Fact) |

| |Each Scheduling Coordinator’s responsibility for Transferred Frequency Response Charges shall be allocated |

| |based on the Scheduling Coordinator’s NERC/WECC Metered Demand. |

| |The NERC/WECC Metered Demand value per Scheduling Coordinator (as identified by its Business Associate ID) that|

| |is used to determine the Transferred Frequency Response Charges shall be provided on the NERC/WECC Information |

| |Statement (as defined for charge code CC 6490 – NERC WECC Charge), the Transferred Frequency Response charge |

| |code Initial Statement, and the Transferred Frequency Response charge code Recalculation Statement. |

| |Within 5 Business Days after receiving the invoice for Transferred Frequency Response Charges from the |

| |Transferred Frequency Response provider, the CAISO shall issue a market notice setting forth the Transferred |

| |Frequency Response charge rate for the assessment year, which shall be calculated using the total Transferred |

| |Frequency Response Charges invoiced to the CAISO divided by the most recent total NERC/WECC Metered Demand. |

| |The CAISO shall calculate the Transferred Frequency Response charges allocable to each Scheduling Coordinator |

| |by using the Transferred Frequency Response Charge rate for the assessment year, multiplying such rate by the |

| |most recent NERC/WECC Metered Demand for that Scheduling Coordinator for the assessment year. |

| |Within 10 Business Days after receiving the invoice for the Transferred Frequency Response charges, the CAISO |

| |shall issue an invoice to each Scheduling Coordinator for its allocable share of the Transferred Frequency |

| |Response charges. |

| |Scheduling Coordinators shall make timely payment to the CAISO within fifteen (15) Business Days of the date |

| |the CAISO issues the invoices.(Fact) |

| |Each Scheduling Coordinator shall have the opportunity to review the terms of the invoice for the charge for |

| |TFR and shall be deemed to have validated that invoice unless it raises a dispute within five (5) Business Days|

| |of the date of issuance. (Fact) |

| |Scheduling Coordinators shall be prohibited from disputing any Transferred Frequency Response Charges, except |

| |on grounds that an error in the invoice is due to a mere typographical or other ministerial error by the CAISO.|

| |(Fact) |

| |If the CAISO determines that an invoice contains a typographical or other ministerial error, the CAISO will |

| |issue a corrected invoice within 15 Business Days of the date the initial invoice was issued. |

| |In the event a Scheduling Coordinator defaults on the payment of all or any portion of the invoiced Transferred|

| |Frequency Response Charges, the CAISO shall have the right under Tariff Section 11.29.13.3 to enforce the |

| |financial security provided by the defaulting Scheduling Coordinator, and to take any such other action under |

| |Tariff Sections 11.29.12 or 11.29.13, as necessary, to obtain payment for the default amount. (Fact) |

| |To the extent all or any portion of the default amount remains unpaid, the CAISO – |

| |may issue an invoice for the unpaid Transferred Frequency Response Charges; and |

| |if such invoice is issued for a payment default, shall allocate responsibility for the shortfall to Scheduling |

| |Coordinators with NERC/WECC Metered Demand, excluding the CAISO Debtor that has not paid the payment default |

| |amount, based on the most recent NERC/WECC Metered Demand for each Scheduling Coordinator. |

| |Scheduling Coordinators shall make timely payment to the CAISO within 15 Business Days of the date the default |

| |invoices were issued. |

| |For Settlements business implementation, the Scheduling Coordinator mentioned in the Tariff shall be identified|

| |using the Business Associate (BA) ID. (Fact) |

| |In the event CAISO reassigns a Business Associate’s (BA) meter data quantity to another BA ID, meter data |

| |quantity PTBs (also applied in the configuration for CC 6490 – NERC WECC Charge) will facilitate both reversing|

| |out and reassigning the original BA ID meter data quantity to another BA ID. |
