Modification 414 and SIS Removal
David Addison
• UNC Modification 414 – Discontinuation of ANS Usage for Interruption Communications by Transporters
• UNC Modification 414 seeks to remove the obligations on Distribution Networks to use the Active Notification System (ANS) to serve notice of:
• Interruption Notices (G6.8.1)• Interruption Requirement no longer exists (G.6.8.5)
• Since Interruption Reform (UNC Mod 090) no Users have opted to receive communications via ANS, preferring telephone or facsimile notification
• UNC Mod 414 seeks to remove the reference to ANS from Appendix 5B in the above instances
UNC Modification 414
• The following changes will need to be made to the Manual:

• Changes will be required to the Manual after UNC Modification has been approved
• As a UNC Modification is required, this should be dealt with as a Class 2 UK Link Modification, but this is expected to have no impacts to Users therefore is proposed as a Class 1 Change
• Update to the manual proposed to be undertaken as a simple administrative change
UNC Modification 414
• Shipper Information Service (SIS) enabled publication of data to UK Link Users
• Service is provided by an out of date application (Lotus Notes) and is not widely used by Users
• Information published has been replaced on other more appropriate mediums, including:
• National Grid website• Xoserve website• Joint Office
• Proposal is to remove SIS, and maintain provision as currently.• Xoserve and National Grid are conducting a review exercise to identify
existing data obligations, and where these are discharged
