Proposed Approach for Handling Changes in End User Categories
As per the agreed guidelines, any new End User Categories (EUCs) will only be updated following existing system rules. A potential need for a new Reconciliation Variance code has been identified to track amended EUCs, specifically in scenarios like Back Billing on Greenfield sites. Although frequent, the new Rec Variance will be utilized only under certain conditions. Xoserve is considering not introducing a new code to avoid additional system changes and complexity.

XRN4665 - New End User Categories As agreed at ChMC new EUC s will only change as per current system rules, AQ Calc, Confirmation Start/Change, Gas Year Reassigning etc It was originally assumed that no new Reconciliation Variance code would be needed due to the EUC s only being updated as part of BAU processes (other reason codes would take precedent over any introduced code for EUC) However, following on from detail design the potential need for a new Rec Variance code has been identified to show where an EUC has been amended One particular scenario Back Billing on Greenfield sites brought about this requirement (detailed on next slide)

Considerations The Back Billing on Greenfield sites occur frequently, however potential new Rec Variance will only be used if the back billing period spans Gas Year 2019 and no AQ Calculation was successful for 01.10.2019 EUC s change each Gas Year (BAU) the Rec Variance used = UGR - Monthly Variance and will be present regardless of introducing a new code EUC values will be present and split within Invoicing Supporting Information Files (e.g AML - K92) showing the EUC values for each variance Trans Inv Type SSC Bill Month Bill Year Invoice # LDZ Market Cat Class Below example is for illustrative purposes only.

XRN4665 DSG Actions Xoserve are proposing not to introduce a new Rec Variance Code as part of this change, due to A new variance code would incur Shipper system changes Add additional complexity regarding the production of supporting information files BAU precedent exists for EUC changes as part of Gas Year Additional regression testing would be needed DSG are being asked To consider the Greenfield Back Billing Scenario and advise if a new Rec Variance Code is needed or would the existing Variance Code (UGR Monthly Variance) be enough? If yes, are there any other instances where EUC Rec Variance Code would take priority over any current codes?
