  3. Call-outs An information only call out. Denotes a change in the process. A BRD reference.

  4. Calculate NDM Output Nominations NDM Demand estimation formula; the formula willl no longer use the Scaling Factor and will apply a Weather Correction Factor calculated from the Forecast Weather data. Formula: (AQ/365)*ALP*(1+[DAF*WCF]) UNC Ref H2.2- Formula C2.5 – Principles of NDM Nominations Weather Correction Factor adjusts for the difference between the Daily Composite Weather Variable and the Daily Seasonal Normal Composite Weather Variable per LDZ. Settlement BRD Ref: 5.1, 5.3 Note There are no file formats associated with this Business Process.

  5. Validate Output Nominations UNC Ref C2.2.6 – D-7 Applicable to Class 1 & 2 Nominations Where a Gas Nomination for a Class 1 & 2 is not submitted, a D-7 estimate will be generated and applied. The estimate will be based on a D-7 Output Nomination. The generation of an estimate will be visible in Gemini and can be replaced within the Gas Nomination timescales. Settlement BRD Ref: 5.1.2 Note There are no file formats associated with this Business Process.

  6. Calculate Forecast Unidentified Gas UNC Ref H2.6 – Unidentified Gas The Forecast Unidentified Gas will be apportioned to Shippers using the Allocation Adjustment Factors. A Unidentified Gas ‘Meter ID’ will be created per Shipper per LDZ / Exit Zone. 3.4.4.2 Publish Forecast Unidentified Gas Forecast Unidentified Gas Available The LDZ Forecast Unidentified Gas is calculated at D-1 for the Gas Flow Day. Calculation LDZ Forecast Demand – (LDZ shrinkage + Total DM Nominations + Total NDM Nominations) Settlement BRD Ref: 5.4

  7. Calculate Energy Allocations UNC Ref E3 Unidentified Gas Available 3.5.3 Calculate LDZ unidentified gas Unidentified Gas value feeds into imbalance position and cash out charges. New NDM demand calculation. The formula will no longer include the Scaling Factor and will apply a Weather Correction Factor calculated from actual weather data. Weather Correction Factor adjusts the difference between the daily CWV and the daily seasonal normal CWV per LDZ. Settlement BRD Ref: 5.3

  8. Calculate Unidentified Gas Allocation The Allocated Unidentified Gas will be apportioned to Shippers using the Allocation Adjustment Factors. Allocated Unidentified Gas Available 3.5.3.2 Publish Allocated Unidentified Gas UNC Ref E1.1.6 E1.1.7 The LDZ allocated Unidentified Gas is calculated at D+1 for the Gas Flow Day. Calculation: LDZ Demand – (LDZ Shrinkage + Total DM Allocations + Total NDM Allocations) Settlement BRD Ref: 5.4

  17. Class Changes24th October 2014

  18. Introduction • This presentation aims to provide an overview of the process for Class change specifically the reconciliation and Check Read processes. • The presentation also covers scenarios where there is a Shipper Transfer and Class change combined. • Where a combined change of Shipper and Class change is associated with DRE/AMR equipment the focus is around apportioning the drift following a Check Read.

  19. Why have a Check Read • Check Reads are required where equipment (AMR) is installed that derives the reads from the meter. • The Check Read identifies where the meter and the equipment are not synchronised and will detect any drift between the meter and the equipment. Any drift is then apportioned across the relevant period. Class 1 and 2 Class 3 and 4 Daily Reads A A A A A A CR CR Reconciliation Reconciliation Reconciliation A A A CR CR

  20. Class Change

  21. Terms Used • DRE: Daily Read Equipment • AMR: Automatic Read Equipment • GFD: Gas Flow Day • CR: Check Read • A: Actual Read • N: Cyclic Read • E: Estimate Read • D: Effective date of the Class Change

  22. General Principles • Where DRE/AMR is installed for Class 2, 3 & 4 the kit is not changed on a Class change only event. • For a change in Class an Actual read is required to close out the outgoing Class. • The Actual Read provided for the effective date of the Class change will not be subject to the read tolerance validations only standard asset validation (serial number, dials and units etc.) • This is because the read may not follow on from the previous read due to the difference between the on-site reading and the derivable reads. • On Class Change only event the Check Read will reconcile back to the previous Check Read or AMR/DRE Installation Read. • When AMR/DRE equipment is installed the first Check Read received will reconcile back to the previous Check Read or Installation Read.

  23. General Principles - Reconciliation • There are 3 steps for energy allocation/reconciliation for Class 3 and 4 Supply Meter Points where AMR equipment is installed • Daily Allocations are based on the Demand Estimation Formula. • An Actual Read received will trigger reconciliations. • Daily for Class 3 • Periodic for Class 4 • Following receipt of a Check Read reconciliation will be triggered back to the previous Check Read • In the cases of a Shipper Transfer this will be the opening read. • Where AMR/DRE is fitted on a Class 3 or 4 Reconciliation will be processed first followed by the Check Read Reconciliation (apportion the drift across the period). • For Class 1 and 2 any replaced meter readings received outside of close-out will trigger Reconciliation.

  24. General Principles – Shipper Transfer • For Class 1 and 2, any reads received following a Shipper Transfer that fail validation will generate an Estimated Read. On receipt of a valid actual read the Estimated Reads will be re-calculated (better estimates) back to the Shipper Transfer/Class change day. • If the Check Read is not provided for the Class change date for a Shipper Transfer within the UNC timescales then an Estimate Read will be calculated and treated as a Check Read. • Class 2 within GFD+5 • Class 3 & 4 within Month+10 • For a Shipper Transfer where the outgoing Class is Class 1 or 2 the D-1 volume will be estimated for Allocation purposes, either using D-7 or AQ/365. • This is to ensure that the drift is allocated to the correct period (previous Check Read) rather than the total drift allocated to the day before the Class change • On Shipper Transfer where AMR/DRE equipment is fitted the Opening Read received will be treated as a Check Read and therefore will trigger Reconciliation back to the last Check Read. This will close out the position for the Outgoing Shipper.

  25. Files Formats • The reads will be provided on the following communication methods: Incoming Methods:

  41. File Changes – No change File Changes - Minor File Changes - Medium File Changes – Major File Changes - New Apply Asset Fault Status (Input) Fault Notified via SFN File for Class 3 & 4. Class 1 & 2 via web portal. If fault flagged in error submit a further SFN File (3 & 4) or portal update (1 & 2) to advise the Fault Notification was raised in error SFN SFR This process flow is repeated in this presentation to demonstrate input and output. Supply Point Register BRD Ref: 8.8 41

  42. File Changes – No change File Changes - Minor File Changes - Medium File Changes – Major File Changes - New Faulty Meter If the fault has been applied in error the ‘suspended’ status is removed. Read Validations are applied Where a fault has been flagged the next read submissions via the UMR/UDR or UBR read files will be suspended. Where a read is suspended a D -7 estimate for Class 1 and 2 will be generated. If the Shipper has raised the fault the DMSP will be notified. UMR UDR Following a fault being flagged any read suspended for Classes 2, 3 & 4 will be notified via URS file. The notification will state: Read suspended due to fault flag. Settlement BRD Ref: 5.5, 5.6 UBR 42

  43. File Changes – No change File Changes - Minor File Changes - Medium File Changes - New File Changes – Major Apply Asset Fault Status (Output) Where a Meter Exchange has been updated the meter will be considered to be faulty. To receive a consumption adjustment an RFA contact should be raised via CMS for fault period between two reads. Where a Corrector Exchange has been updated the meter readings and previous check read will be used to automatically reconcile the fault period. The submission of RGMA ONJOB File to update a Meter or Corrector Exchange will end date the fault against the faulty asset. If the fault is on the Daily Read Equipment, notification of the site visit information will be required either via the portal or the SFN file in order to end the fault. Where Daily Read Equipment is installed automatic reconciliation will go back to the previous check read using convertor reads or meter reads. ONJOB SFN SFR Note: If a Meter or Converter Exchange is updated for a day during the fault period it will be treated as if the meter is faulty and a consumption adjustment must be provided. Note: If you wish to correct the consumption fault period within Exit Close out you can view the portal for Class 1 & 2 sites. Supply Point Register BRD Ref: 8.8 43 43

  45. iGT Single Service Provision – non-effective days to support cutover A presentation to: iGT Shipper Workgroup 3rd November 2014 UNC Nexus Workgroup 4th November 2014 See also the iGT single service provision data preparation and migration overview report published on the Joint Office website

  46. iGT Single Service Provision – non-effective days to support cutover • To move to the iGT Single Service provision arrangements a number of activities are required • At some point the iGT systems must close • There are then a number of activities to prepare arrangements for the UK Link system – particularly around finalising the data for migration. • The UK Link system will then open • A period of time is required to prepare the UK Link system. During this time supply point register updates and supply point administration communications cannot be made. • This does not mean that events cannot occur on these days or that updates cannot be made that are effective on these days.

  47. iGT Single Service Provision – non-effective days to support cutover • Six non-effective days for the purpose of supply point register (SPR) and supply point administration (SPA) communications • This means that SPR and SPA communications cannot be sent to an iGT on these days • The six days are September 25,26,27,28,29,30 • The last day a Shipper can send a SPR or SPA communication to the iGT is Thursday 24th September • From 1st October Shippers will send SPR and SPA communications to the UK Link system

  48. iGT Single Service Provision – non-effective days to support cutover • Why six days are needed • Working back from 1st October 05:00 hrs • The data to support Gemini processes (balancing etc) needs to be in Gemini for the start of day D-2. D is 1st October, D-2 is 29th September 06:00 • This means the data is loaded to Gemini on 28th September • The source of the Gemini data is the Data Preparation Database • The Data Preparation Database must have a final position on 28th September circa 13:00hrs • On 27th the data will be subject to check and re-check, no new data will be added to the Data Preparation Database on this day. (The final shipper portfolio will be issued from this closed-out position) • The last processing of data on the Data Preparation Database is the 26th September • The last date iGTs can submit data is 25th September • Therefore the last day the iGT can accept files for processing for them prepare the final data for submission to Xoserve is 24th September

  49. iGT Single Service Provision – non-effective days to support cutover • What are the implications of this? • The “faster switching” timescales, which create the minimum period for a transfer (14 calendar days starting from the day after the confirmation file is received), will not apply for the six days • To effect a change of shipper event on 9, 10, 11, 12, 13, 14 October the confirmation file must be submitted to the iGT by 24 September • Any updates to the SPR e.g. asset update, meter reading etc that would ordinarily be submitted between 25 and 30 September will need to be submitted to Xoserve from 1st October using the new file formats. • There is no opportunity to “back-date” files. All files processed from 1st October will be processed and validated against the receipt date of the file

  50. iGT Single Service Provision – non-effective days to support cutover • Confirmation of SPA and SPR files processed pre and post cut-over • SPA events that start in the iGT system and end in UK Link will be migrated with no impact to the event. However, Shippers need to be aware that apparent unsolicited files will be received. • The effective date of any SPR updates processed after 1st October will be maintained e.g. a meter exchange on 25th September will be recorded as having happened on the 25th September
