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 Intermittent Resources Program (PIRP) was implemented on Trading Day 6/2/2004 enabling intermittent resources (wind and other resources with an uncontrollable primary fuel source) to participate in CAISO Markets. PIRP scheduling methodology allows participating intermittent power producers to schedule Energy in the CAISO HASP/RTM while reducing their exposure to hourly imbalance charges whenever the delivered Energy differs from the scheduled Energy.

The CAISOshall provide each Participating Intermittent Resource (PIR) with independent third party Hour-Ahead Energy forecasts. Currently, the independent third party is AWS True Wind Company. The Scheduling Coordinator representing the PIR, must submitting HASP/RT Self Schedules tht are identical, in aggregate, to the Hour-Ahead Forecast. In addition to the Hour-Ahead forecasts, AWS will provide Day-Ahead forecast for each PIR for each Trading Hour for the following Trading Day. The SC can use these Day-Ahead forecasts as an advisory or the SC can schedule in the Day-Ahead Market. However, if the PIR schedules in the DAM, they are exposed to daily imbalance energy charges.

Forecasting Service Fee Charge Code 701 charges Business Associates for each PIR for the daily Energy generation forecasts provided by an external Forecast Service Provider. The forecasting service company provides a Day Ahead forecast for each PIR for a Trading Hour for the following Trading Day, as well as updated hourly forecasts as needed. All BAs for PIRs are charged a FERC approved forecasted service rate per MWh based on actual metered Energy.

2.2Description

The Forecasting Service Fee is automatically calculated by the Settlements system on a monthly basis at the resource specific level and summed by Business Associate for the Settlement Statement and Invoicing. The forecasted service rate is approved by FERC and per MWh based on actual metered Energy

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
