Date: 8/31/09
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
2.1 Background
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 RealTime 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).
2.2 Description
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 MSS
Operators net MSS Demand. 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 nonParticipating Demand is calculated at the Settlement Interval level and summed up to
hourly values.
For eligible Participating Intermittent 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 Participating Intermittent Resources. At the end of the
month, the daily Real Time UIE Settlement Amount for the eligible Participating
Intermittent Resources shall be reversed in Charge Code 722 Intermittent Resource Net
Deviation Reversal and a monthly netted UIE Settlement Amount in CC 711 shall be

assessed. In addition, 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.

quantity and its’ Resource-Specific Tier 1 UIE Settlement Interval Price.
3.0.1
The Resource-Specific Tier 1 UIE Settlement Interval Price for each Settlement
Interval shall be calculated for the resource by dividing its Settlement Interval total
IIE amount, calculated in CC 6470, and its total IIE Energy quantity.
3.1
The total IIE Energy quantity shall be calculated as the sum of all instructed Energy
quantities associated with the Settlement Interval total IIE amount calculated in CC
6470; and this Charge Code calculation makes use of two quantities calculated in
