  5. Ofgem aspirations • Requirement to survey all sub-deduct networks in Britain • GDPCR Final Proposals – 3rd December 2007 • Allowance for surveys • To be completed over 2008/9 and 2009/10 formula years • Purpose • to gather technical data relevant to potential re-engineering and future adoption of these networks by GDNs • To inform the anticipated DBERR review of the relevant exemption order (Statutory Instrument 1996/449) due to expire on 1st March 2011 • Final report to Ofgem 1st April 2010 • Method for conducting work dependant on resources and experience of each GDN

  6. Next steps • National Grid is considering the most effective way in which it is able to meet Ofgem’s requirements • Options for Survey resourcing are currently under consideration. • Use of direct labour. Shipper liaison to be facilitated by ‘customer’ department. • Outsourcing to contractors by competitive tender. Contractor responsible for all Shipper/Supplier/Customer interfaces. • A method of capturing data in a consistent way needs to be developed • Confirm ownership of Primary/Sub-deduct Supply Point/User • Consistent method of contact with end-consumer needs to be agreed (contact letters, etc) • Extent of NGD liaison with Shipper/Supplier of key importance
