1.Purpose of Document
The purpose of this document is to capture the business and functional requirements for the MRTU SaMC Real Time Uninstructed Imbalance Energy Settlement, Charge Code 6475.
2.Introduction
2.1Background
With the implementation of MRTU, the current radial zonal model will be replaced with Full Network Model and Locational Marginal Price (LMP) model, which will also eliminate the use of Zones for the Settlement of Energy transactions. Locational Marginal Prices will be used in principle to settle Energy transactions. Price Locations and Aggregated Price Locations are defined on collections of network nodes. A LMP will be calculated for each Price Location and each Aggregated Price Location.
The Real-Time Market (RTM) is a market for trading Energy and Ancillary Services in Real Time. The bid submission for a given Trading Hour in the RTM is allowed after the Day Ahead Market result publication for the corresponding Trading Day and up to 75 minutes before the start of that Trading Hour. The Real-Time Market processes optimize Energy and Ancillary Services Bids with an objective of satisfying Real-Time Energy needs, mitigating Congestion, allowing resources providing Regulation service to return to preferred operating point within their regulating ranges and allowing recovery of Operating Reserves utilized in Real Time operation.
The Real-Time Economic Dispatch (RTED) is responsible for dispatching Imbalance Energy and Ancillary Services at regular intervals. RTED runs automatically every 5 min, at the middle of each 5-min interval. In addition RTED can be executed manually in Manual or Contingency Dispatch modes. Instructed Imbalance Energy (IIE) resulting from RT dispatched instructions will be calculated by CAISO usually by the end of next Trading day.
The CAISO calculates and accounts for Imbalance Energy for each Dispatch Interval and settles Imbalance Energy for each Settlement Interval for each resource within the CAISO Control Area and all System Resources Dispatched or scheduled in Real-Time.
Imbalance Energy consists of following:
IIE - Real Time Instructed Imbalance Energy Settlement (CC 6470) and HASP Energy, Congestion, Loss Pre-Dispatched Settlement (CC 6051)
UIE - Real Time Uninstructed Imbalance Energy Settlement (CC 6475)
UFE - Real Time Unaccounted for Energy Settlement (CC 6474)
To the extent that the sum of the Settlement Amounts for IIE, UIE, and UFE does not equal zero, the CAISO will assess Charges or make Payments in Real Time Imbalance Energy Offset (CC 6477) for the resulting differences to all Scheduling Coordinators based on a pro rata share of their Measured Demand for the relevant Settlement Interval.
In the Real-Time Market, the negative and positive Congestion Charges associated with a valid post-Day-Ahead TOR and ETC schedule change (including changes submitted to the Hour-Ahead Scheduling Process and changes submitted closer to Real-Time where allowed by the contract) will be reversed in CC 6474 RT Instructed Imbalance Energy Settlement on the Settlement Interval. Because Congestion Charges are implicitly collected by the CAISO in the Real-Time settlement and there are no holders of rights to receive Real-Time Congestion revenues under the MRTU design, all charges for Real-Time Congestion will be accumulated in a special and separate neutrality account to be distributed back to non-ETC Control Area metered Demand and exports on a per-MWh basis in Real Time Congestion Offset (CC 6774).
2.2Description
The Real Time Uninstructed Imbalance Energy (UIE) Settlement Amount is the payment or charge due to or from a resource for its UIE. UIE Settlement Amount consists of two components:
Tier 1 UIE (UIE1) Settlement Amount, accounts for deviations’ from resource IIE
Tier 2 UIE (UIE2) Settlement Amount, accounts for deviations’ from resource Day Ahead schedule.
For Generating Units, MSS Operators that have elected gross Settlement, System Resources, Participating Load and Pumping Load, the Tier 1 UIE Settlement Amount is calculated for each Settlement Interval as the product of its Tier 1 UIE quantity and its’ Resource-Specific Tier 1 UIE Settlement Interval Price. The Tier 2 UIE Settlement Amount is calculated for each Settlement Interval as the product of its Tier 2 UIE quantity and the simple average of the relevant Dispatch Interval LMPs.
For MSS Operators that have elected net Settlement, the Tier 1 UIE Settlement Amount is calculated for each Settlement Interval as the product of its Tier 1 UIE quantity and its’ Real Time Settlement Interval MSS Price. For MSS Operators that have elected net Settlement, the Tier 2 UIE Settlement Amount is calculated for each Settlement Interval as the product of its Tier 2 UIE quantity and its’ Real Time Settlement Interval MSS Price.
There is no Tier 1 UIE Settlement Amount for non-Participating Demand and MSSOperatorsnet MSSDemand. Tier 2 UIE Settlement Amount for non-participating Demand is calculated for each Settlement Interval as the sum of Tier 2 UIE LAP Settlement Amount and the Tier 2 UIE Neutrality Amount, where Tier 2 UIE LAP Settlement Amount is calculated for each Settlement Interval as the product of the Tier 2 UIE quantity and the Hourly Real-Time LAP Price. The UIE Settlement Amount for non-Participating Demand is calculated at the Settlement Interval level and summed up to hourly values.
For eligible Participating Intermittent PIR Resources, the CAISO Tariff allows for monthly netting treatment of UIE in Charge Code 711 Intermittent Resources Net Deviation Settlement. As such, this Charge Code shall initially calculate a daily Real Time UIE Settlement Amount for eligible PIRParticipating Intermittent Resources. At the end of the month, the daily Real Time UIE Settlement Amount for the eligible PIRParticipating Intermittent Resources ashall be reversed in Charge Code 722 Intermittent Resource Net Deviation Reversal and a monthly netted UIE Settlement Amount in CC 711 shall be assessed.. Instead of calculating the PIR Real Time UIE Settlement Amount for eligible PIR resources, this Charge Code will calculate the PIR Real Time UIE Settlement Accrual Amount. In addition,Based on PIRP, the difference between the monthly netted UIE Settlement Amount calculated in CC 711 and the sum of PIR Real Time UIE Settlement Amount shall be settled in CC 721, Intermittent Resources Net Deviation Allocation.
