  1. DN Interruption Phase II 27 January 2011

  2. Supply Type InitialisationProposed Solution • Shippers to re-confirm all on demand LDZ interruptible supply points using current processes with an effective date of 01 October 2011 to: • Change the supply type status to firm • Set the NDM SOQ or DMSOQ & DMSHQ parameters • Correct transportation invoicing • Ensure compliance with UNC MOD090 • For any sites remaining unconfirmed by a back-stop date, it is proposed that they will be reconfirmed by the Transporter on the current Registered User’s behalf

  3. Benefits • Shippers will nominate the correct Supply Type and receive an appropriate Supply Point Offer for the nominated values. • Shippers will be able to confirm supply points with GNT permitted by code • NDM or DM (DMM, DMV or DME) • Updates both Transporter and Shipper systems. • Provides an opportunity to review and set the DM SOQ & DM SHQ: • DMSOQ for Interruptible Supply Point will not have increased in line with daily consumption (although BSSOQ will have been reset once per year). • Supply Points confirmed as Firm DM will be subject to the LDZ capacity ratchet regime.

  4. Supply Type Initialisation Shipper / xoserve indicative milestones July ‘11 April ’11 April - xoserve will issue to Shippers interruptible portfolios to current Registered System Users together with Appeals to change the supply type through the usual process April – May – Shippers to review portfolio and SOQ/SHQ Shippers nominate using appropriate appeal reference Networks process appeals in the normal way – allow time for referrals May – Shippers advise of any amendments to Registered System User, DMSOQ, DMSHQ, GNT Change May onwards – xoserve issue revised appeals as required The above dates will be subject to change and are dependent on the commencement of technical evaluation.

  5. Restricted transfer dates • Re-confirmation of LDZ Interruptible supply points with requested effective dates between 08/09/11 - 19/10/11 will be rejected • These confirmations would prevent a correct transfer for 1st October • Where a Shipper has a supply contract (incoming Shipper) due to commence between these dates where effective date is other than 01/10/11, incoming Shipper will need to notify xoserve. • Transportation adjustments can be processed for the period where the RSU doesn’t align with the customer contract.

  6. Supply Type Initialisation Proposed Solution - Timeline The above dates will be subject to change and are dependent on the commencement of technical evaluation.

  7. Backstop process • Any sites remaining unconfirmed by the ‘back-stop date’ would be re-confirmed by the Transporter on the current Registered System User’s behalf • xoserve will advise the Registered System User of any sites that remain unconfirmed to ‘firm’ by the ‘back-stop date’ • xoserve will create .NOM and .CNF files for each Shipper • If required, copies of files can be issued to Shippers • File names will be previously unused references • SOQ/SHQ values used in that confirmation will be exactly as held in Sites and Meters at that time, regardless of any appeal raised by Shippers earlier in the year • Current Shipper and Supplier and current emergency contacts will also be utilised • Files would be processed through UK Link and normal response files generated • Files may be issued to Shippers • TRF files would be issued to Shippers at D-7 • Same process would be operated for Unique Sites but carried out off-line
