7 XRN4361 UK Link Release 2 XRN4249 Part B Data Migration Plan

8 Introduction/Problem Statement Change XRN4249 is part of the scope of changes planned to be implemented as part of UK Link Release 2 on the 29 th June Following analysis of this change, discussion was held with Customers at both ChMC and DSG. Concerns were raised around the migration of the PAF updates from when the process was suspended in April These concerns relate to the volume of updates required over the period April 17 through to June 18 that could have a downstream impact to Customer systems and business processes. To minimise the impact of loading all retrospective PAF updates from April 2017, Xoserve are recommending a staggered approach to migrate the data over a number of weekends. This would have checkpoints built into the plan to review the process and agree the volume of updates to be loaded on the next planned date. This approach is expected to reduce the impacts to Customer systems and business processes.

11 UKL Future Release 2 Cutover/Implementation

12 Background At the DSG on 23 rd April, there was a Customer query on the Release 2 Implementation Plan to confirm file exchange and processing

13 Query Response Based on the analysis conducted, it is recommended that adhoc jobs are triggered for all files where file formats will be changed as part of R2 implementation (CNC,CNF,SFN and ACR) Adhoc processing will be triggered at 23:00 hours on 29 th June 2018 to cover all pending data to be processed for the business day All outbound response files for CNC,CNF,SFN and ACR will be processed and submitted before 23:59 hours on 29 th June 2018 in the old file format CNC,CNF,SFN and ACR inbound files submitted after 23:00 hours on 29 th June 2018 will be held at the Xoserve gateway and will be processed post R2 Go Live as per the agreed implementation plan CNC,CNF,SFN and ACR inbound files submitted after 23:00 hours on 29 th June 2018 are expected to be in the new file format (validation will be completed by AMT and file rejections sent if in the old format for CNC,CNF,SFN and ACR) GT (EDL & EWS) & igt (IDL) Portfolio outbound files will be sent in the old file format for the final time on Saturday morning. The new file formats will be submitted from 01/07/18 (IDL files will contain migrated PSR data for igts, GTs will receive EDL files that do not include migrated PSR data as EQL & EWS files will include this data on the files to be sent on 02/07/18) As part of the lower level implementation plan we will agree a communication plan with \Customers

This does not impact the start to Build phase. A Plan/Time Cadent & NG design overview sessions are in progress and expected to continue for the first 2 weeks to ensure all requirements for XRN 4454 are successfully catered for within Design. 14 Change Packs have been published for Release 3 scope. Approval to be sought at additional Change Management Committee Meeting arranged for 2 nd May. Risks and Issues High Level Design playback was presented to DSG in April. Engagement to be undertaken on Market Trials & Implementation approach with DSG over the next 8 weeks to define the Approach and timelines. R3 Delivery plan has a degree of parallelism. Risk is being closely monitored, slight delay to completion of Design phase however Build can commence as planned and slippage can be recovered NG and Cadent requirements finalisation and sign off required to complete XRN 4452 this is underway. Notional Go Live Date dependent on close management of parallelism in plan and other elements i.e. Market Trials approach Cost Full Delivery costs approved at ChMC in April and forecasts are currently within budget. Resources Weekly monitoring of SME resources supporting multiple demands Currently we have SMEs booked to support all Detailed Design discussions.

25 AQs of 1

26 Negative Consumption within the AQ Calculation

27 Overview Negative Consumption is generated when a Shipper submits a subsequent Actual read that is less than the last Xoserve Estimated read on UK Link (without a TTZ count). This occurs in UK Link when Xoserve provides Estimated Readings in the following scenarios: Change of Shipper event Class change LDZ / exit zone change A new fail to calculate reason was introduced where an AQ calculation was not calculated owing to negative consumption. This was applied to negative consumption's created from legacy meter readings where read validations were less stringent.

28 Overview Negative consumption generated post 01 st June 2017 is considered valid with the introduction of more stringent Meter Read validations Negative Consumption is included within AQ Calculations Reads can be replaced by the User registered on the date of the Meter Reading. With the exceptions of: Readings connected to RGMA updates Actual Reads on Class 1 and Class 2 SMPs

29 Increase in AQs of 1 / Understated AQs There has been an increase in the number of AQs of 1 and understated AQs as a result of a lower actual meter reading being submitted following an Xoserve estimated reading This has occurred where the transfer reading is the AQ closing reading, and therefore not taken into account with the AQ calculation. The next meter reading, which is an actual, is the AQ opening read. Only the negative consumption is considered within the AQ calculation Analysis shows the maximum impact is less than 0.03% of total NDM AQ, therefore this is not considered a high material impact

30 Options for DSG discussion 1. Shipper Action Replace the Xoserve estimated reading and submit a subsequent meter reading which will trigger a new rolling AQ calculation. The AQ will be a correct reflection of the gas being consumed on the SMP. These meter readings can be submitted at the same time. Considerations If this action is completed the SMP will have a reflective AQ There are no impacts to UNC rules/calculations with this solution This retains the original requirement from Nexus that all reconcilable reads should be used for AQ calculation Any UIG implications will be rectified once the readings are taken into account within reconciliation

31 Options for DSG discussion 2. Apply Fail to Calculate validation for all negative consumption period Extend the code previously introduced whereby negative consumption is excluded from AQ calculations and the prevailing AQ is carried forwards Considerations The prevailing AQ will be in situ until there are 9 months of accurate readings and a new AQ can be calculated, impacts NDM gas nominations, any further estimated transfer reads (should it transfer) will generate poor estimates Less meter points will be subject to regular rolling AQ updates UNC Modification 0638V and 0570 are both implemented which enact the CMA order and the requirements for all Users to submit reads (0638V - monthly where smart and AMR is present and annual read submission with 0570). PAC are monitoring performance and may choose to incentivise Read submission

32 Other Options for DSG discussion 3. Another AQ correction reason for example- the last calculated AQ is not a reflection of the annual AQ Considerations Would correct the AQ Creates a back stop date however analysis on SMPs impacted do not have a frequent read submission profile. Yes leave in question do DSG have further solution options 4. Option for the system to recalculate the estimated transfer read based on previous read and latest submitted actual Would require further analysis and complete impact assessment
