  1. iGT Single Service Provision Requirements Update – 27th March 2013

  2. Background • Original set of requirements for iGT agency services developed and baselined under Project Nexus UNC Workgroup back in August 2012 • Further development of the requirements has continued with the iGTs and GTs over the past 6 months • An updated set of conceptual process models and requirements has been created and baslined with the iGTs • The requirements focus on the differences for CSEP Supply Meter Points and should be considered along with the other Project Nexus requirements documents

  3. Requirement Topic Areas • The iGT Agency Services Business Requirements Document (BRD) contains the following topic areas: • General iGT requirements • CSEP Setup & Lifecycle • CSEP Supply Meter Point setup & initial Shipper registration • Network referrals & transportation offers • Meter Reads & Must Reads • Queries • iGT Invoicing • Termination & Insolvency • Portfolio Reporting

  4. High Level Process Overview Shipper Confirms CSEP Supply Meter Point Includes Shipper Notification of Asset Installation iGT / MAM Installs Xoserve Provides Data iGT Requests iGT Requests CSEP Creation CSEP Supply Meter Point Creation Asset Installation Shipper Registration iGT Invoicing BAU Processes GT Notified Shipper Notified Shipper & Suppler Notified iGT Notified iGT Issues

  5. CSEP Creation Process

  6. CSEP Data Overview

  7. CSEP Maintenance Process

  8. CSEP Supply Meter Point Creation Process

  9. CSEP Supply Meter Point Creation Process

  10. Deviations From GT Processes • CSEP Creation • CSEP Supply Meter Point Creation • Issuing of a provisional Shipper confirmation on SMP creation • Nominations for an I&C SSP CSEP Supply Meter Points • Issuing of a Confirmation where Shipper has not Confirmed a new CSEP Supply Meter Point following the asset installation • Referrals for CSEP Supply Meter Point updates • iGT invoicing arrangements

  11. Required iGT Referrals • CSEP Supply Meter Point capacity changes are required for a greater range of SMPs • AQ corrections will require referral to the relevant iGT to ensure the correct rates are applied and notified to the Shipper • Address amendments will be validated by the relevant iGT prior to any updates being made on central systems • Market Sector Code changes will be verified by the relevant iGT to ensure the correct rates are applied and notified to the Shipper

  12. Areas for Further Consideration • Managing the market setup for an organisation • Rules for the capture of a shipper acceding to the iGT UNC • Rules around setting up a new iGT organisation • Maintaining an organisation’s market participation • Rules around iGT mergers, de-mergers & acquisitions • Managing the market exit of an organisation • Impacts of a Shipper withdrawing from the GT UNC • Rules around Shipper terminations, especially where triggered by DNOs or EBCC • Rules around the withdrawal of an iGT

  13. Areas for Further Consideration • Managing the ownership of a CSEP • Rules around the transfer of a CSEP between IGTs • Especially impacts on the MPRN and the CSEP SMP history • Rules around the adoption of a CSEP by a DNO • Impacts of a GT nesting of CSEP

  14. Outstanding Issues • Requirements for CSEP Daily Metered Mandatory (DMM) sites have not been fully captured • CSEP Overrun charges / ratchets for CSEP DMM sites need further consideration • Reporting requirements and data access entitlements need to be defined

  15. Next Steps • Agree and baseline the requirement changes contained with version 1.1 of the Project Nexus iGT Agency Services BRD • Resolve outstanding issues during future UNC Mod 0440 / iGT UNC Mod 039 workgroups • Further detailed evolvement of the requirements
