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 Positive Uninstructed Deviation Penalty (UDP) Settlement Charge Code 4480 is intended to discourage Scheduling Coordinators from deviating from their forward schedules and/or any CAISO instructions. This charge should result in increased predictability of Generators and improved operational stability of the CAISO. Charges are assessed against Uninstructed Imbalance Energy quantities that result from resource deviations outside a Tolerance Band from their Dispatch Operating Point, for dispatched resources, or their Day-Ahead Schedule otherwise.

For this calculation, the Compliance Business Unit will calculate Uninstructed Deviation Quantities. Resources represented by the same Scheduling Coordinator and connected to the same CAISO Controlled Grid bus and voltage level can be aggregated for purposes of netting uninstructed deviations among the aggregation. The Compliance Business Unit will also provide a Penalty Location ID, which will uniquely identify each aggregation. Prior to the data being received by the Settlements Business Unit, the Compliance Business Unit applies all applicable exemptions, except for those specifically stated in the exemptions document.

Positive Uninstructed Deviation Penalty Settlement Amounts assessed in CC 4480 are summed with Negative Deviation Penalty Settlement Amounts in CC 4470, as well as CC 6482 Real Time Excess Cost for Instructed Energy Settlement and CC 6486 Real Time Excess Cost for Instructed Energy Allocation, to determine the allocation methodology. If the net sum of these Charge Codes is negative, this amount is charged to Measured Demand in CC 6480. If the net sum is positive, this amount is passed to the Market Clearing system as a balancing Billing Determinant for accrual in the Surplus Account (as described by the CC 6480 configuration guide).

**This charge has not yet been approved by FERC and therefore must be left out of the Billing and Invoice Process. Positive Uninstructed Deviation Penalty Quantity is currently being provided to the market on an advisory basis only.

2.2Description

The Positive Uninstructed Deviation Penalty Settlement charges are calculated on a 10-minute interval basis at a Penalty Location level and summed by Scheduling Coordinator for the Settlement Statement.
