1. Project Smart Metering Portfolio Foundation & DCC Day 1 UpdatesApril 2013

2. Agenda • Implementation of Effective Switching Changes • Effective Switching • Approval of File Formats for: • Smart Switching • Implementation Date for Smart Switching • Effective Switching - Back Population Approach • Smart Switching - Back Population Approach • DCC Day 1 Analysis Update

3. Effective Switching Implementation • Xoserve successfully implemented the Effective Switching system changes for Foundation on 29th March 2013 for: • UK Link • Additional Allowable Values for Meter Mech Code added (NS, S1 & S2) • Installing Supplier ID • IP • SCOGES File Format Change – Addition of MME Code, Installing Supplier ID & SMSO ID • Data Enquiry Service • Community View – Addition of Installing Supplier and SMETs value • Portfolio View – Addition of Installing Supplier, Meter Mech Code will continue to display the current values as well as the new SMETs value

4. Approval of File Formats for Smart Switching Phase • As part of the February pack, new file formats were presented for Smart Switching Changes (GEA & GEO) – Comments were received. • Org_Type length of 3 was challenged why it was not 4. As previously communicated changes to the Org Type field length would have wide ranging impacts so this is rejected. • An additional field called Status is now presented in the revised file formats with 2 allowable values (Live & End Date) • Revised File Formats have been re-distributed under ref. AT/1183.2/JF and UKLC are asked to formally approve these for an implementation date of 01/10/13 • As this is a new file format it is has been assumed Shippers will want to undertake User Trials – planned for a period of 2-4 weeks

5. Implementation Date for Smart Switching • Proposed ‘Notional’ Implementation Date of 1st October 2013 • SPAA Schedule 23 Change raised to reflect this date • Due to proximity to AQ Review and constrained processing period, actual implementation date is likely to be prior to 1st October 2013. • Xoserve are currently assessing dates in August / September but may elect an alternative date. • Implementation Plan Summary will show the base-lined ‘notional’ implementation date – i.e. 1st October 2013 • Intention is that the Committee will be informed of progress and planned implementation via updates through UK Link Committee • As this implementation does not impact existing file flows, but creates a new flow it is expected that the actual implementation date being earlier should NOT impact Users.

6. Effective Switching Back Population Approach • Challenges to activity due to the GRP implementation on 8th/9th June 2013. • Xoserve have written to Shippers, who have indicated they have large portfolios of Smart Meters, to ascertain the volume of Smart Meters in each Suppliers Portfolio. • Analysis in progress to look at planned approach for volume of ONUPDs

7. Smart Switching Back Population Approach • Back Population approach to be agreed in full with Shippers but will require the GEA file to be provide all updates • Xoserve have written to Shippers for Effective Switching to ascertain the volume of Smart Meters in each Suppliers Portfolio that will be used to analyse the impacts. • Analysis will look at the volumes acceptable through the GEA file to back populate the SMSO for all Smart Meters

8. DCC Day 1 Analysis Progress Update • 5 Focus Group Workshops held to date with Shippers, iGT’s & DECC. • BRD V0.6 submitted to Shippers for review, a number of parties have already provided review comments that have been responded to by Xoserve. • Final date for Shipper review comments is Friday 19th April and no further comments will be accepted post this date. • The Focus group will be presented the solution design options being considered that will form the Detailed Cost Analysis. • Once the DCA is completed, delivery timescales will be known and agreement will be sought formally from SPAA & UK Link Committee for the implementation date of DCC Day 1 Changes. • Focus Group will continue to meet throughout the Project.
