Title: National Grid Gas Fossil Fuel Transfer Costs National Grid Gas (Distribution) Content: Detail on the conditions under which this cost is valid: * All costs in 2009/2010 prices * Financial Year 2013/14: * Fixed OPEX costs 2013/14 = £/a 530m * Fixed Capital Costs 2013/14 = £/a 720m * Financial Year 2021/22: * Fixed OPEX costs 2021/22 = £/a 420m * Fixed Capital Costs 2021/22 = £/a 855m * Costs of decommissioning the entire Gas Distribution Network is in the region of £4,088m (Source: ENA). * Costs are largely independent of volume, scenarios that indicate reductions in energy conveyed are not likely to materially impact on the fixed cost element. Assuming a cost per unit of energy may lead to inaccuracies in cost calculations. * Specific replacement programme relating to metallic pipe assets between 2002 and 2032 assumed in investment. Between 2013/14 and 2021/22 it has been assumed that 25% of replacement costs have been expensed within year. * Operational costs relate to repair, maintenance and the provision of the gas emergency service - these costs remain fixed in line with geographical requirements for existing assets. Limiations of this cost estimate * Costs have been based on National Grid's 4 gas distribution network regulatory plans. * Figures would need to be doubled to provide an estimate of the total costs for GB's gas distribution grid (accounting for the 4 distribution networks not owned or operated by National Grid).
