National Grid Electricity Transmission National Grid Electricty Transmission 2012

Category Electricity Transmission
Source National Grid
Capital cost £m(2010)97.8/GW 98£m(2010)/GW
Year for which cost is valid 2012 2012


Items that this cost includes

Items that this cost excludes:

  • This cost should exclude grid distribution costs (they should be in distribution cost data)
  • This cost should exclude the cost of carrying electricity from new generation to the nearest grid access point (that should be in the cost of the individual generating technology).

Detail on the conditions under which this cost is valid

  • All costs in 2009/2010 prices
  • Costs provided based on National Grid's Gone Green future energy scenarios utilised by National Grid in their RIIO subsmission.
  • Financial Year 2012/13:
  • RAV(£bn):8.8
  • Opex(£m):320(TO & SO)
  • Grid Connections: 90GW

£8.8bn / 90GW = £97.8m/GW.

  • Financial Year 2020/21:
  • RAV(£bn):15.9
  • Opex(£m):373 (TO & SO)
  • Grid Connections: 100.0GW
