Change Management Committee Sections 2-6 Review
The Change Management Committee conducted a comprehensive review of new change proposals, focusing on improving nomination processes and flow rates. The proposals aim to enhance user flexibility and streamline validation procedures, benefiting shippers, DNOs, and National Grid. The proposed changes address issues with Single Sided Nominations and Negative Implied Flow Rates, offering automated solutions and flexibility in managing gas flow processes.

2.1 XRN5053 Single Sided Nominations Improvements Voting Parties and Funding Split Change Details Problem Statement Voting Party? Funding Split (%) Customer Class The Gemini System does not currently allow a user to have both a Single Sided Nomination (SSN) and a Double Sided Nomination (DSN) for the same date/location combination. Where a user has submitted a SSN that is not then matched by the adjacent TSO the user is unable to amend it or submit a new request for that same combination. The TSO BBL does not accept SSNs and so if a user incorrectly submits a SSN they are then unable to submit a DSN instead. Shipper Distribution Network Operators (DNOs) National Grid Transmission Y 100% Independent Gas Transporter Change Description Impacted Parties:- Shippers and National Grid There are 3 elements to the change request, in priority order: 1A) Ability to Withdraw SSNs Introduce a withdrawal facility whereby a user can withdraw a SSN that has not been confirmed. Once withdrawn the user would be able to place a new request. 1B) Ability to Modify SSNs Introduce a modify facility such that users can change the various elements of a SSN that has not been confirmed. This would include the ability to change it from a SSN to a DSN. 1C) Error proofing SSN entry For a SSN we could introduce an auto populate facility for key fields such as the EIC whereby the value entered in the internal shipper EIC field is then copied across to the external shipper EIC field.

2.1 XRN5054 Negative Implied Flow Rates Voting Parties and Funding Split Change Details Problem Statement Voting Party? Funding Split (%) Customer Class Shippers are unable to process renominations where there is a breach of the 1/24th rule, current arrangements dictate that the shipper must send a fax to request a reschedule to National Grid Gas National Control Centre who will manually validate and reschedule. This is time consuming, with many requests received daily from Customers to the National Grid Gas National Control Centre to action. This is prone to error and is only actioned on a current best endeavours basis. Customers are requesting this change from recent workshops that have been held for Gemini Enhancement Project to allow them more flexibility in managing the process. Shipper Distribution Network Operators (DNOs) National Grid Transmission Y 100% Independent Gas Transporter Impacted Parties:- Shippers and National Grid Change Description Automated Solution for negative implied flow rates for Customers and National Grid. The renominations will be placed by the Customer (via online screen/API) where the negative implied flow validation will be processed into requests for reschedule process by the Gas National Control Centre.

4.1 New Change Proposals Post Solution Review Agenda Item XRN / Title Proposed Release Link to Change Proposal Comm Ref DSG Preferred Option and date Solution Summary Outcome and implementation date outcome Comments Organisation Approve Defer Reject 4.1 XRN4923 - AQ Calculation for RGMA (ONUPD) Estimate Reads npower X Should any suggestions be made by others during this representation we believe they should be reviewed for suitability without impacting the implementation date. eon X Proposed for February Minor Release Drop 6 Could you confirm how the read estimation is calculated ,my understanding is that it is currently calculated using the current AQ, meaning the new AQ will likely to be similar or the same. Can you please clarify what the benefit of the change is? Link to Change Proposal Only 1 solution available. Scottish Power X Link to Change Pack ref 2489.9 - RT - PO MiR Drop 6 We do not support option 1 if UPD flows sent as part of a Change of Shipper/Supplier event are not treated differently (wait to estimate any read until after end of window for a Supplier to provide a customer or other opening read that could be validated and used in preference to a possible inaccurate estimate). We also do not see the benefits this will bring as estimated read will be generated using AQ and last read and so will not benefit the rolling AQ process EDF X
4.2 XRN4851 - Moving Market Participant Ownership from SPAA to UNC/DSC
Solution Approach At the DSG session on 18th November, multiple approaches for the new Market Participant process were presented (A simple spreadsheet solution/a file flow similar to the electricity process). These approach options have also been circulated to various Industry groups. The consensus view is that a downloadable spreadsheet is the best approach This was also the recommendation from DSG Previous assumptions were that a file flow was required, similar to electricity processes, which we will continue to investigate should there be an appetite for this for those that commented they indicated that they did not want the elec flows replicated We are seeking confirmation from ChMC that this approach is supported for the Market Participant process from Feb 20.

Functional Changes XRN / Title Solution & Implementation Summary outcome Comments Xoserve response Deferred Organisation Approve Reject XRN4850 Notification of Customer Contact Details to Transporters NGN X npower X We have spoken to W&W who have approved the date and solution concept and are awaiting on additional clarification. (Reps never gave a representation status and rejected the date) Change Pack ref: 2489.14 - RT PO W&W X As per our previous response and phone conversation we Xoserve - we stand by the belief that this proposed solution is over-engineered and all that was needed was a broadcast flag - which could be used if contact type of CON. If set this would then mandate addition data. This would have mitigated the need to have made so many changes to existing records and duplication of data items being sent Link to CP June 2020 Release EDF X
Functional Changes XRN / Title Solution & Implementation Summary outcome Comments Deferred Organisation Approve Reject XRN4930 Requirement to Inform Shipper of Meter Link Code Change Npower X SSE X Change Pack ref: 2489.5 - RT PO We have no desire to use this functionality. Prime & Sub meters are due to be phased out and there are extremely low numbers remaining. We do not feel this warrants a flow change. Link to CP EDF X June 2020 Release
Functional Changes XRN / Title Solution & Implementation Summary outcome Comments Deferred Organisation Approve Reject XRN4932 Improvements to the quality of the Conversion Factor values held on the Supply Point Register (MOD0681S) Npower X Eon X Orsted X Scottish Power X NGN X Change Pack ref: 2489.6 - RT PO XRN5027 really needs to be looked at and agreed before this is in place. We need to ensure data is as accurate as possible before implementing this solution as inaccurate data for this value will impact customer billing Link to CP EDF X June 2020 Release
Functional Changes XRN / Title Solution & Implementation Summary outcome Comments Deferred Organisation Approve Reject XRN4941 Auto updates to meter read frequency (MOD0692) NGN X Npower X Orsted X Change Pack ref: 2489.11 - RT PO Scottish Power X We are supportive of the solution and have no concerns on this, however, we are not supportive of the implementation date proposed, currently the modification has not been approved nor been given direction on when the principles will become effective in code. We would prefer this approved with the 6 months implementation notice post modification approval, therefore we suggest Nov 2020 implementation instead of June 2020. We approve this where AQ changes above 293000kwh However we reject the other instances - we do not believe that data held by CDSP will always be accurate or within out control and therefore this will lead to problems e.g. decisions on MRF will be potentially based on inaccurate information such as meters which are defined as S2 by some iGTs but will never be in DCC. Also once DCC flag is active it cannot be switched off even if it is apparent that data is wrong so again will never be smart. In these instances we will be expected to read monthly and will not always be able to do so. Link to CP X X June 2020 Release eon Solution Date EDF X
