These include: Gas transmission charging: Potential industry-led Uniform Network Code \('UNC'\) changes linked to the ongoing National Gas Transmission \('NGT'\) consultation on: 'NTS GCD 13 - Impacts of Existing Contracts on Transmission Services Charges'\. Potential industry-led changes to the General Non-Transmission Services \('GNTS'\) methodology\. Capacity neutrality arrangements \(linked to issue ref\. CMF003 and CMF008\)\. Gas access arrangements\. Gas Security of Supply\. Shrinkage arrangements\. Gas System Operator \(GSO\) incentives\. Identifying areas of reform ahead of RIIO-T3\. Gas connections\. The contract is managed by the Gas Charging & Access team\. Contract activity will cover some base tracking and review of ongoing activities \(e\.g\. including tracking national transmission system charging methodology form \(NTSCMF\) and Transmission Workgroup\) together with specific work \(including analysis, exploration of issues with team members, development and review of change proposals, policy development etc\) as agreed from time to time\. The bulk of the contract's time would be associated with specific activities as agreed with the contract manager and will include bi-directional background briefing and knowledge sharing\.
