2 1. Introduction On September 28 th, 2017 at the Shipper Allocation Working Group (SAWG) meeting Enbridge indicated that new allocation process changes would be in place for the October 2018 production month. For this month Enbridge will provide a full product Plant to Receipt Point allocation and the upstream allocation from Receipt Point (RP) to Production Source (PS) will become the responsibility of the Receipt Point Operator (RPO). This approach had been proposed by the RPO community on several occasions to eliminate the overlap in responsibilities between Enbridge and RPOs. This document provides a draft proposal for a Download / Upload file format to be used in conjunction with the new process. A set of samples are provided with this document for illustration purposes. Note that the sample is a formatted MS- Excel document but the actual file(s) would be unformatted comma separated values (CSV) files. Each month according to the calendars published on the Customer Interface, Enbridge will make available to each RPO an initial download file. This download will contain the completed results of the Plant to RP allocation for each RP that an RPO operates for the specified production month and will be available in either a monthly or daily format. If the monthly format is chosen, the initial download will contain monthly total product allocations for each RP and the RPO will be expected to upload PS monthly totals which sum to the same values for each RP product provided in the download. Enbridge will then generate daily values for each PS by initiating a pro-ration routine based on the daily PS estimates as provided for the Intra Day Shipper Allocation. If the daily format is chosen, the initial download will contain monthly AND daily product allocations for each RP and the RPO will be expected to upload daily PS amounts which add up exactly to the RP total for the month. Enbridge will also check that the PS amounts uploaded for the day add up to the RP daily total within an acceptable tolerance. Subsequent sections of this document provide the proposed file format and details on how Enbridge would likely process the file. 2. Sample File Description The attached sample uses the same simplified allocation example presented at the Sept. 28 th SAWG discussions. It also uses the same color scheme: Colour Orange Green Grey Blue Interpretation Enbridge calculated & supplied RPO calculated & supplied Shown for information only & not included in download or upload Intermediate values used in Enbridge s calculation & not available externally (Only used in the accompanying spreadsheet) 19 January 2018 For Discussion Purposes Only Page 2

3 The sample file contains 4 tabs: Tab 1 Depicts a monthly Plant to RP download sample Tab 2 Depicts a daily Plant to RP download sample Tab 3 Depicts a monthly RP to PS upload Tab 4 Depicts a daily RP to PS upload PS Allocation Example 2.1 Header Row The first row of the file is a header row identifying the columns in the file: Row Type Date Allocation Cycle Production Source Id Plant Receipt Point Id Receipt Point Name Petrinex Id Production Source Owner Shipper Raw 103m3 Gathering Fuel 103m3 Plant Fuel 103m3 H2S 103m3 Acid 103m3 Sulphur Tonnes C3 m3 C4 m3 C5+ m3 Residue 103m3 Residue GJ Individual columns are discussed in the next section. The order of columns in the file is fixed. 2.2 Data Rows Row Type If the row type column contains the content Comment the entire row is ignored. This allows comments or diagnostics to be embedded in the file for informational, development or troubleshooting purposes. RP_Monthly_Total_Download row types are provided by Enbridge in both the monthly and the daily version of the download and represent the total for the month at an RP.. The PS totals uploaded by the RPO must always exactly sum up to match this row. 19 January 2018 For Discussion Purposes Only Page 3

4 RP_Daily_Total_Download row types are provided by Enbridge and represent the total for each day of the month at the RP. This row is only provided if the daily version of the download has been generated. If the RPO is choosing to provide a daily allocation, the sum of the PS totals for each day must match the totals provided in this row to within a stated tolerance (the tolerance is detailed later in this document). PS_Monthly_Upload row types are returned by the RPO and represent the total for the month at each PS. This row type is ONLY used if the RPO is providing a monthly allocation and expecting Enbridge to do the month end daily allocation. PS_Daily_Upload row types are returned by the RPO and represent the total for each day at each PS. This row type is ONLY used if the RPO is providing a daily allocation. The RPO will use either PS_Monthly_Upload, or, PS_Daily_Upload type rows to provide the RP to PS allocation but not both for the same RP. A file containing multiple RPs may contain both Daily and Monthly rows, providing that no one RP uses both. A row type of Last on the last record is used for both the upload and download to indicate that the file is complete and that a partial file has not been provided due to an error in transfer. Rows in the file after the Last indicator are not processed. Date The valid date format is YYYY-MM-DD. i.e for October 1 st, All rows in the file must reference the same month. For daily type rows a row for each day in the month is required. For monthly type rows the first of the month is recommended as a convention but only the month component of the date is used. Allocation Cycle One of the following codes indicating the current allocation cycle for the month: ACT - Actual Cycle C01 - Correction Cycle 01 C02 - Correction Cycle 02 C03 - Correction Cycle PS ID The unique identifier for an Enbridge PS (new Producer/Shipper ID). This column is empty for download file rows where Enbridge is providing RP values. For upload file rows the unique PS ID is required. Plant This column is provided for information purposes but is optional and is never processed. It contains the text name for the plant. 19 January 2018 For Discussion Purposes Only Page 4

5 Receipt Point ID The RP ID is the unique Enbridge identifier for an RP. This field is optional upon upload as the PS uniquely identifies an RP. Receipt Point Name The RP Name is the text description for a RP. This field is optional upon upload as the PS uniquely identifies the RP. This field is never processed. Petrinex Identifier The Petrinex Identifier is the unique Petrinex identifier for an RP. This field is optional upon upload as the PS uniquely identifies an RP. PS Owner The PS Owner is the text description for the party that owns the PS. This field is optional upon upload as the PS uniquely identifies the owner and shipper. This field is never processed. This column is empty for download file rows where Enbridge is providing receipt point values. Shipper The Shipper is the text description for the Shipper at the PS. This field is optional upon upload as the PS uniquely identifies the owner and shipper. This field is never processed. This column is empty for download file rows where Enbridge is providing receipt point values. Numerical Product Columns Decimal precisions for the numerical columns are: 0 decimals for energy in GJs 1 decimal for all volumes in 103m3 and sulphur tonnes 1 decimal for C3, C4, C5+ liquids (New these products have historically been allocated to three decimals by Enbridge and are now to be allocated to one decimal to match the industry standard) The required product columns are: Raw 103m3 Gathering Fuel 103m3 This product is provided in the download version of the file. In the upload version of the file if this field is left blank, Enbridge will calculate it by prorating across Production Sources using the Raw 103m3 as a basis. Plant Fuel 103m3 19 January 2018 For Discussion Purposes Only Page 5

6 H2S 103m3 This product is provided in the download version of the file. In the upload version of the file if this field is left blank, Enbridge will calculate it by prorating across Production Sources using Sulfur as a basis. Acid 103m3 Sulphur Tonnes C3 m3 C4 m3 C5+ m3 Residue 103m3 Residue GJ 3 File Processing The following rules are to be applied upon each file upload event. 3.1 Handling of Errors The upload process will always endeavor to process the entire upload file. If the results for an individual RP do not pass all the validation checks mentioned above then that RP will be flagged as invalid. RPs in the same file that pass validations will be loaded successfully. The user will then have the option of providing another upload for the invalid RP with all invalid data corrected. 3.2 Allowable Time Range All records in an upload file must reference the same calendar month. 3.3 Complete RP At a minimum each upload file must contain a complete allocation for one RP. One or more RPs may be referenced in a given upload file. The RPO has the option of uploading all RPs in one file, as one RP per file, or any combination thereof. If an RP to PS allocation is uploaded multiple times prior to the deadline then the prior upload is discarded and the most recent upload supersedes it. 19 January 2018 For Discussion Purposes Only Page 6

7 3.3.1 RPs With Zero Totals for the Month RPs with zero totals for the month do not require an upload. PS Allocation Example 3.4 Processing of Row Types Monthly Row Types Where users submit only Monthly rows, Enbridge will subsequently create daily PS allocations by prorating across all the days of the month using the PS intraday Estimates for the month Daily Row Types Ensure that the PS totals on the day match the RP totals on the day within the proposed tolerance and that the PS totals on the month match the RP totals exactly Comment Rows Any row with a row type of Comment in the first column is ignored. This is to allow extra rows to be added to the file for troubleshooting or informational purposes. 3.5 Processing of individual Columns Processing of Numeric Columns For each column with numeric content, a total by RP for the month is generated and compared to the Receipt Point s PS total for the month. The RP and PS totals must match exactly for each product or the file will be rejected. In the case of daily PS allocations provided by the RPO, the sum of the daily PS numbers must be within a tolerance of the daily totals at the RP as originally calculated by Enbridge (please refer to Point 4 below). The proposed tolerances are: Volumes: The greater of 1.0 or 5% Energy: The greater of 40 GJ or 5% Liquids: The greater of or 5% 3.6 Reporting of Errors If one or more errors occur during the upload process the user will be presented with a window listing all of the errors that occurred. The user will have the opportunity to save a copy of the error file to assist with the troubleshooting process. 4 Other Considerations In order to meet industry deadlines downstream of this process, Enbridge will provide an initial Default allocation and will consider the Default to be accurate in the event that a submission is not provided for an RP by the RPO by the published deadline. 19 January 2018 For Discussion Purposes Only Page 7
