  37. Aggregation input file data: MPRN Supplier Unit SSAC DLF Usage factor by time of use Load Profile 2. ESBN records at the time of the aggregation run: MPRN DG Load Factor (if MD) Usage Factor Load profile per time of use Whether actual or estimated consumption MCR 0063 - Provision of reconciliation data MCR ready for circulation. Requirement: For all MPRNs included in a specified aggregation run, 2 data extracts on request: 37

  38. MCR 0063 - Provision of reconciliation data • Assumptions • Suppliers can validate QH Export Aggregations by using the existing data (Generator Unit / Export Arrangement). • Timing of extract runs to fit in with the live production schedule • Output format will not be in the form of new messages • The frequency and costs of producing the reports would need to be discussed as an MRSO item at future IGGs. 38

  39. DR 0117 New Status Message for Meter Works and Special Read requests • Where we are: • DR0177 circulated and agreed • New IGG Action (18.10.2007): • add the list of codes • clarify how these messages tie in with chargeable and non chargeable transactions (in DUoS)when there is a cancellation. 39

  40. DR 0117 (contd.) Current Meter Works Outcomes 40

  41. MCR 0127 - Decouple Connection Agreement requirement from Change of Supplier • In order to maximise potential value to suppliers, will request impact on the following alternative proposal: • Removal of CA requirement for all MPRNs connection at low voltage. • Advantages: • Would remove a larger number of sites from the requirement. • Compatible with NI design. • DSO are in agreement in principle 41

  42. Market Change Request DR 0113 Supplier of Last Resort Update DR ready to be circulated to the market • SoLR Process Assumptions • For a defaulting Supplier only.

  43. Market Change Request DR 0113 Supplier of Last Resort Update • SoLR Assumptions • Alternate Suppliers are obliged to cancel 010 CoS’s submitted after day 19 for MPRNs on the day 1 CSV file • Alternate Suppliers will not receive Customer Name for domestic MPRNS (existing market rules). • Meter Work service orders to be analysed case by case. • All 010 messages for SoLR MPRNs to contain the new SoLR Read Arrangement Code. • Analysis work and actions will be carried out by MRSO and ESB Networks on MPRNs with certain statuses. 43

  44. Market Change Request DR 0113 Supplier of Last Resort Update New Working Practice • A new working practice will be initiated from this DR to provide guidelines on how to handle: • Disputed reads • Inaccurate / poor estimates readings (e.g. withdrawals, present < previous) • Meter works 44

  45. Next Schema Release • June 2008 • Prioritised MCRs/DRs: • DR 117 – Meter Works status message • MCR 0063 – Aggregation Reconciliation Data • MCR 0127 - Decouple CA and CoS • SoLR Read Arrangement code value Status: • No impact as MCRs are not complete. Need to complete rapidly to facilitate development. 45
