Project Nexus Consultation Responses IRR Ref Requirement Outcome 1.5 There is a requirement for basic profile data to be provided to allow accurate quoting and purchasing. Included 1.7 Raise an enquiry on Small Supply Points (SSPs) and receive back the same information as currently received for the Large Supply Points (LSP). 1.10 When a consumer exercises their right to change supplier, the industry needs to consider if it is prepared to share consumption data with other Shippers. 10.6 Support multiple suppliers/shippers per legal entity. This would avoid the need for bulk transfers and allow shippers to easily establish parent and subsidiary account relationships to enhance corporate balancing, settlement and invoicing efficiency. npower to clarify 10.13 Bad debt risk. There may be merit in xoserve gauging industry’s views on the merits and practicality of, and need for, maintaining a record of supply points that have a history of bad debt. Closed 11.3 Control of static non-commercial industry data. Data items such as those relating to end users’ address details which are considered to be static should have an increased centralisation of maintenance activities to ensure consistency across the industry. Out of scope

Project Nexus Consultation Responses cont. IRR Ref Requirement Source 13.11 More direct relationships between the Meter Asset Manager (MAM) and xoserve Closed 13.25 Remove the manual processes currently associated with shared supply points and unique sites. Included 13.27 Systematize processes that are currently managed outside of the core system For example, unique sites, primes and subs, etc Included 10.9 Inclusion of Unique Sites database within Nexus. We believe that there are benefits in structuring the core data in such a way that a flexible and fully inclusive service is provided to cater for all differing contractual relationships that can be associated with Supply Points. The primary change to xoserve’s services in this respect would be a common platform for all core data, for example Unique Sites, CSEPs etc. Included

Requirements Raised in other Workgroups AMR & Settlement Workgroup; Check Read information - Included Requirement for the GT to notify the Shipper the date the Check Read was due [1] month after the Check Read due date. In order to do this the relevant data items to monitor the Check Read requirement will need to be recorded by the GT. Supply Point Enquiry (Mod 0357) - included Provision of consumption data to the Shipper Requirements already developed, review required Reconciliation, Invoicing & AQ Workgroups; More categories for the Market Sector Flag - included PN UNC Single Meter Point Supply Points - included
