Workgroup Assessment of Impacts of the modification on the Relevant Objectives. Impact of the modification on the Relevant Objectives: Relevant Objective Identified impact a) Efficient and economic operation of the pipe-line system. Positive – 0621A/B/C/D/K b) Coordinated, efficient and economic operation of (i) the combined pipe-line system, and/ or (ii) the pipe-line system of one or more relevant gas transporters. None c) Efficient discharge of the licensee's obligations. Positive – All Modifications d) Securing of effective competition: (i) between relevant shippers; (ii) between relevant suppliers; and/or (iii) between DN operators (who have entered into transportation arrangements with other relevant gas transporters) and relevant shippers. Positive – All Modifications e) Provision of reasonable economic incentives for relevant suppliers to secure that the domestic customer supply security standards… are satisfied as respects the availability of gas to their domestic customers. None f) Promotion of efficiency in the implementation and administration of the Code. None g) Compliance with the Regulation and any relevant legally binding decisions of the European Commission and/or the Agency for the Co-operation of Energy Regulators. Positive – All Modifications Efficient and economic operation of the pipe-line system 0621A: Based on analysis carried out by Storengy and WWA there is a clear relationship between the physical operation of storage facilities and the pipe-line system. The strong, positive correlation between aggregate gas demand and storage withdrawals/injections means that National Grid, in its role as SO, benefits from gas storage, at no cost. The flexibility provided by gas storage provides direct support to National Grid in its role as system balancer throughcontributing to linepack managementand reduced activity and costs associated with National Grid’s participation in the balancing market (OCM) or any other contractual arrangements it may choose to enter into as part of its network balancing toolbox.
