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

Grid Management Charge Codes are monthly charges assessed on 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 and financing as well as 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.

Market Usage Forward Energy contains the activities associated with determining the market prices, maintaining and controlling the OASIS, monitoring market performance, ensuring generator compliance with market protocols, and calculating the results of the Integrated Forward Market.

2.2Description

In order to reflect a participant’s impact on the maintenance, monitoring, operation, and performance of the Forward Energy and Real-Time markets, the Market Usage (MU) Forward Energy Charge Code is calculated based on the maximum of the absolute value for energy purchases or sales in the Day Ahead Market (DAM). This charge will settle based on the maximum of the absolute value for energy purchases or salesfor each Scheduling Coordinator by Trading Hour.

3.Charge Code Requirements

3.1Business Rules

Bus Req ID / Business Rule
1.0 / This charge is a daily charge settled on the last day of each month.
2.0 / Where input Bill Determinants are not daily, or activity across a Bill Period is required to determine the appropriate Settlement Amount, the Charge Code shall be calculated on a monthly basis and output on the last Settlement Statement fora Trading Month
2.1 / Where input Bill Determinants are daily, the Charge Code shall be calculated and output on a daily basis and summed to a Trading Month Value for invoicing.
3.0 / 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 / This Charge Code is based on the Day Ahead net energy purchases and sales across by Scheduling Coordinator’s portfolio by Trading Hour.
