Title: National Grid Electricity Transmission National Grid Electricty Transmission 2012/13 and 2020/21

Content: 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.
