Draft Scope Proposed in Open Letter • Legislative guidance documents • e.g. IGE recommended practice documents • Planning legislation and consents process • e.g. Implications for investment lead times • National Grid policies relevant to planning and development of NTS • e.g. assessment of new loads, design of NTS pipelines and installations • Network Analysis techniques • e.g. considerations for investment planning, how physical capability is determined • Supply and Demand Outlook • e.g. how TBE forecasts are used in investment planning

  4. Responses • 4 non-confidential responses received from • E.ON • Centrica Energy • RWE npower • Scotia Gas Networks • Broad support for the principles of transparency in network planning that will be delivered by the Transmission Planning Code (TPC)

  5. Update of Transmission Planning Code • Responses queried how and when the TPC should be updated • UK and EU Legislative updates/proposals • The TPC will be revised after relevant legislation is implemented or updated, as NGG is required to comply with the TPC that is in force • Informal updates and discussions through workshops can be used to develop industry understanding of issues and likely impacts e.g. on investment lead times • Governance process • TPC modifications will be governed by the process set out in NGG’s GT Licence for the NTS

  6. Information within TPC (1) • Responses queried the detailed information required in the TPC • Publication of National Grid NTS Policies • The TPC will contain information on the NTS planning process which will include appropriate planning policy information • Publication of network model data and results • The TPC is intended as a framework document to describe planning processes under Special Condition C11 of the GT Licence • The Network Model will be consulted on as part of NGG’s obligations under Special Condition C24

  7. Information within TPC (2) • Practical implications of legislation • The TPC will describe how legislation affects the planning process including how lead times are impacted • The TPC will describe the legislative background to NGG’s Safety Case for the NTS • Supply/demand uncertainty • The TPC will describe how uncertainties in supply and demand scenarios presented in the Ten Year Statement are addressed in network planning and development • Investment Drivers • The TPC will describe how TBE information and user commitment signals are each used to drive investment
