Purpose:
This document describes the format of the Settlement Statement Files which are issued by the California
Independent System Operator (ISO) to its market participants. The content of these files are subject to change as the
California Independent System Operator refines its business requirements. Permission to copy this document is
hereby granted for purposes of interfacing with the California Independent System Operator (ISO).
The Settlement Statement File contains the charge information for a market participant. Its data are mostly for a
particular trading date, but it may also contain missing charges from prior trading dates. It has a summary section
that aggregates the charges by Charge Type and Trade Date. There is also a detail line item section that contains a
detail breakdown of the charges. There are several companion files issued with the Statement File. These currently
include:
 GMC, Wheeling & Market Uplifts Detail File;
 HVAC Detail File
 HVAC and Wheeling Revenues Detail File
 Ancillary Service Detail File;
 Imbalance Energy/No Pay Settlement Detail File; and
 Settlement Prices File.
The Imbalance Energy/No Pay Detail File contains a detail breakdown by resource location and trading interval of
the expost deviations of the market participant’s generation, load, and intertie schedules. It also contains the
parameters that are used to derive the participant’s Unaccounted for Energy (UFE) and No Pay charges. The GMC,
Wheeling & Market Uplifts Detail File contains a detail hourly breakdown of the market participant’s Grid
Management Charges and Wheeling Charges. The High Voltage Access Charge (HVAC) Detail File contains the
detail supporting data that are used to derive the monthly HVAC shown in the Statement File. The HVAC and
Wheeling Revenue Detail File contains a detail breakdown of the revenues collected by location and trading hour for
a Transmission Owner. The Ancillary Service Detail File contains the detail supporting data that are used to derive
the corresponding Ancillary Services charges shown in the Statement File. The Settlement Prices File contains
relevant prices used to calculate various settlement charges. These include the MCPs by trading hour (or trading
interval) for energy and Ancillary Services, monthly MCPs for PIRP, service rates for forecasting daily energy
generation for each PIR, as well as GMC, HVAC and Wheeling rates.
533561091
2 General Notes:
Some general notes about the Statement Files are listed below:
 Market participants will download both files through the ISO Scheduling Infrastructure interface.
 Each weekday, the ISO Settlement System will generate two different types of settlement statements. One type
is the preliminary statements for a trading day; the other is the final statements for a different trading day.
Currently, the preliminary statement will normally be issued the evening of the 47 th day after the trading day.
The final will be issued the evening of the 51st business day after the trading day. If the issuing day happens to
be a weekend day or a holiday, the statement will be delayed until the following business day. Customers may
download their own statement files after they are generated.
 The companion files are issued at the same time as the Statement Files. Thus, each Preliminary or Final
Statement set will contain 4 files.
 Charge amounts due ISO will be positive numbers.
 Refund amounts due market participants will be negative numbers.
 All Statement Files are plain ASCII files with data fields delimited by the ‘pipe’ symbol ( | ). Two consecutive
rows (or records) are separated by a line feed character. It should be noted that when such files are downloaded,
some client systems may also insert a carriage return between the rows.
533561091
3 Settlement Statement File
There are two statements (preliminary and final) issued for a given trading date. Currently, the preliminary and final
statements for a given trading date are issued 14 days apart. Both statements have the same statement number, but
they are identified by the statement type.
Each preliminary statement file contains the best available listing of settlement detail and manual line items for the
trading date being settled. Also included in the file may be new settlement line items that are for days prior to the
trading date being settled but have not been included on any previous preliminary statement.
Each final statement file contains the best available settlement line items which have appeared on the preliminary
statement for the corresponding trading date. The quantities in these line items may have been revised though.
There are five different types of data records in a Settlement Statement file. These include:
 Header – This is the first record of the file that provides the information such as the file type, market participant
ID, statement number, trading day and an indicator to show whether it is the preliminary statement or final
statement for that date.
 Summary – These are summary records that show the dollar amounts due aggregated by charge type and trade
day.
 Detail Line Items – These are detailed records of charges by trading interval, location, zone and charge type as
appropriate. These records contain the Billable Quantity, Price and Amount Due as well as a number of other
fields which uniquely identify the charge (such as location, zone, trading interval) or represent the terms used in
the deriving the charge. In a data field where an attribute is not relevant, this field will be left empty between its
delimiters. For example, “Zone 1||10|2|-20” indicates a ‘null’ field between ‘Zone 1’ and the value ‘10’.
 Manual Line Items – These are detailed records of charges entered manually by ISO Settlement Analysts.
These items may be adjustments to previous charges as a result of dispute resolution or other charge items
allowed in the ISO tariff, but whose charge calculation are not yet automated in the Settlement System.
 Trailer – This is the last record of the file. It contains the record count and a validation total which is the total
of the Amount Due fields in the file.
The following is a detailed description of the data fields in the Statement File.
Note : The following charge types are modified for the Metered Sub-system (MSS) BAs.
4401(Instructed Energy); A GMM of ‘1’ is applied for the Internal Generation of the MSS Locations while
calculating the Instructed Energy.
4406 (UFE Settlement): The MSS will be treated as a UDC, and the MSS_BAs will be charged based on the Net
flow from or to the MSS and other NCPA resource.
1401 (Imbalance Energy Offset): The MSS BAs will be allocated based on Non-MSS Metered Demand plus the
MSS Net Metered Demand
1210 (Existing Contracts Cash Neutrality Charge/Refund): The MSS BAs will be allocated based on Non-MSS
Metered Demand plus the MSS Net Metered Demand
Emissions Cost Recovery charges and Start-Up Cost Recovery charges shall be allocated in the same manner as
MLCC beginning Trade Date 12/01/2007. The following charge types have been created in the Charge Type Matrix
v18.6:
5911-Emissions Cost Recovery - Neutrality Allocation
5917-Emissions Cost Recovery - Tier 1 Allocation
5918-Emissions Cost Recovery - Reliability Service Cost Allocation
5919-Emissions Cost Recovery - Inter-Zonal Congestion Allocation
5921-Start-Up Cost Recovery - Neutrality Allocation
5927-Start-Up Cost Recovery - Tier 1 Allocation
5928-Start-Up Cost Recovery - Reliability Service Cost Allocation
533561091
5929-Start-Up Cost Recovery - Inter-Zonal Congestion Allocation
The amount to be allocated for each “bucket” shall be the proportionate share of Start-Up Cost or Emissions Cost
based on the percentage of FERCMOO MLCC amount allocation in each corresponding “bucket.”
1302(Long Term Voltage Support due ISO): If the MSS satisfies their own Voltage Support obligation, they are
exempt from this charge, however the MSS BAs will still be charged based on their Non MSS Metered Demand for
the applicable zone. If the MSS does not satisfy their own Voltage Support obligation, they will be charged based
on the Metered Demand for all the Locations (irrespective of whether the location is part of an MSS or not).
