1. Introduction 1.1 Purpose The purpose of this document is to capture and record a description of what the Users and Business Stakeholders of the project wish to obtain by providing high-level business requirements. This document establishes the basis for the agreement between the initiators and implementers of the project. The information in this document serves as input to determining the scope of Information Systems projects and to all Business Process Modeling and System s Specifications efforts. These requirements will serve as the initial set of business unit requirements for the appropriate software application/systems development effort. It is understood that additional requirements and systems analysis may produce To Be Business Process Models, System s Specifications, and Use Cases to serve as the set of requirements documents used by the development teams to buy, modify, or build the necessary software and hardware systems. The Business Unit(s) involved in the project will have an opportunity to review and approve all requirements documentation produced. 2. Details of Business Need/Problem 2.1 Description Due to the recent bifurcation of the Western Electricity Coordinating Council (WECC), a separate independent company, Peak Reliability, was formed to perform the reliability coordinator services previously performed by WECC. Because of this change, the ISO expects to start receiving an annual direct bill from Peak for reliability coordinator services beginning in November 2015. Objective: Passing on the annual direct bill for reliability coordinator service from Peak to SCs. Include an adjustment for the SCs amount of the RC Charges in calculation of collateral requirements and other credit requirements. Change settlement and payment process to issue an initial and recalculation statement of reliability coordinator service charges or default payment to SCs. Revise Tariff section 11.20 to give the ISO authority to bill and collect for reliability coordinator charges. 2.2 Justification The ISO believes that it is more likely that the alternative funding agreement will be completed and executed in time to fund 2016.

Manage Market & Reliability Data & Modeling Level II - Manage Credit & Collateral (Logical Group) o Adjust financial security amounts. 4. Business s The sections below describe the Business Processes and the associated Business s involved in the project. These may represent high level functional, non-functional, reporting, and/or infrastructure requirements. These business requirements directly relate to the high level scope items determined for the project. 4.1 Business Process: Manage Market Billing & Settlements 4.1.1 Business s BRQ010 System shall calculate the RC charge rate to SCs. RC charge rate = Total RC Charges invoiced to the CAISO / (Total NERC/WECC metered demand). eterra BRQ020 System shall calculate the allocation of RC charges to each SC as follows: eterra RC charges to one SC = RC charge rate * (NERC/WECC Metered Demand for that SC). BRQ030 System shall calculate the Peak Initial statement within 5 Business Days from CAISO receiving the invoice for RC charges. eterra Page 5 of 8
BRQ031 Within 5 Business Days after CAISO receives the invoice for Reliability Coordinator Charges, Settlements shall issue a market notice setting forth the RC charge rate for the relevant assessment year.

Settlements BRQ060 The ISO shall include the RC charges in the next available Peak invoice to collect the unpaid RC charge defaults. Settlements Note: This is discretionary to avoid billing for a nominal amout of unpaid charges.
