5 Effective Switching Back Population Approach • SPAA Change creating Allowable Values is not implemented until 01/06/2013 • Challenges to activity due to the GRP implementation on 8 th/9 th June 2013. • Back Population proposed using ONUPD* • Analysis in progress to look at planned approach for volume of ONUPDs • Shippers to provide a sample file for testing * Option analysis requested – report back pending

New File Type for Smart Switching Phase of the Foundation Stage of SMIP 6 • INPUT – – A new reusable File Type and Record will be created to facilitate the transfer of the new SMSO ID and Effective Date data items for the Smart Switching phase. – The SMSO ID and SMSO Effective Date will be mandatory data items within the new record. • OUTPUT – – Not planned to have Output files for Foundation. – The SMSO Effective Date will not be played back for Foundation on DES. • MDD change proposal to be raised for new Market Participants for SMSO IDs. Values to be agreed with SMSO organisations and Xoserve to ensure values are unique.

7 New File Type for Smart Switching Phase of the Foundation Stage of SMIP • The File Level Validations: – The SMSO ID will be a 3 character text field – The SMSO Effective date will be standard date format (8 characters) • The Record Level Validations: – The SMSO IDs agreed with SPAA will form the allowable values. If a non allowable value is received the following error code will be generated and sent. Suggested code: Error Code: SMO 00001 Error Description: SMSO Does Not Exist • Note: There will be no validation to check if there is a corresponding Smart value in the Meter Mechanism Code when an SMSO ID is provided

8 Implementation Date for Smart Switching • Issue with AQ review impacting the planned Smart Switching Implementation Date of 01/10/2013 requiring Xoserve to implement outside of this window. – Proposed implementation in early Sept 13 outside of key AQ Review activities to protect the UK Gas Industry – System changes would be in place in advance of Shipper Licence Obligation to submit SMSO values from 01/10/13
