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
2.1 Background
The Participating Intermittent Resource Program (PIRP) protective measures give certified PIRP resources utilizing older technology a three-year transition period for preparing for and adapting to the functionality of FERC Order 764. The transition period for these resources will run three years from the implementation of the market design changes for FERC Order 764, or until a new bilateral agreement for power purchases is executed for the resource, whichever comes first. If a resource is certified as a PIRP resource and qualifies for the protective measures after the three-year transition period starts to run, the resource will be subject to the protective measures for the remainder of the transition period or until a new bilateral agreement for power purchases is executed, whichever comes first.
The Participating Intermittent Resources will be charged/paid daily in Charge Code 6460 (FMM Instructed Imbalance Energy), Charge Code 6470 (Real Time Instructed Imbalance Energy), Charge Code 6475 (Real-Time Uninstructed Imbalance Energy Settlement) and Charge Code 6486 (Real Time Excess Cost for Instructed Energy Allocation). The prior mentioned settlement amounts will be reversed at the end of the month in Charge Code 722 (PIR Net Deviation Reversal Settlement Amount) for all Business Associates with Net Negative Uninstructed Deviations in the corresponding Trading Month. Then, the PIRP resources will be re-settled in Charge Code 711 (Intermittent Resources Net Deviation Settlement) based on the monthly net uninstructed imbalance energy (UIE) and the weighted-average RTD price over The Trading Month. Net amounts from the sum of the reversal amounts in CC 722 and the resettled amounts in CC 711 is then allocated to net negative deviators for the Trading Month under CC 721 (PIRP Net Deviation Allocation).
2.2 Description
CC 711 implements the resettlement of IIE and UIE of resources qualified under PIRP Protective Measures, following the business rules provided in the next section.
3. Charge Code Requirements
3.1 Business Rules
Bus Req ID / Business Rule /1.0 / Qualified resources under PIRP Protective Measures shall have their IIE and UIE for the month, resettled at the end of each Trading Month.
2.0 / The hourly IIE of a resource under PIRP Protective Measures shall be its hourly schedule excluding any Day-ahead schedule. The hourly schedule is provided as a 90-minute-in-advance hourly forecast.
2.1 / This hourly IIE shall be settled at the simple average of the five-minute (RTD) locational marginal prices.
2.2 / This hourly IIE resettlement amounts shall be accumulated at the end of the Trading Month to come up with the monthly value.
3.0 / Deviations between the resource’s actual energy output and the hourly schedule will be netted over each month. This quantity represents the monthly UIE of the resource.
3.1 / The monthly UIE will be settled at the weighted average of five-minute (RTD) locational marginal prices over the month, with weights based on the actual energy output (metered output) of the resource every five-minute over the month.
3.2 / The monthly UIE quantity is also known as the Monthly PIR Net Deviation Quantity, and is calculated daily but settled as a Monthly amount.
4.0 / For adjustments to the Charge Code that cannot be accomplished by correction of upstream data inputs or operator over-ride, Pass Through Bill Charge logic will apply.
