Notes
Detail on the conditions under which this cost is valid:
- All costs in 2009/2010 prices
- Financial Year 2012/13:
- RAV(£m) 4,686
- Opex (£m) 390 (TO & SO)
- Annual Throughput: 966 TWh
- Financial Year 2020/21:
- RAV(£m) 7,956
- Opex (£m) 475 (TO & SO)
- Annual Throughput: 946 TWh
- Cost of decommissioning the National Gas Transmission System is in the region of £4,527m (Source: National Grid)
- Limitations of this cost estimate
- 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.
