================ Netherlands - BritNed link
National Grid and NLink - a subsidiary of TenneT, the Dutch transmission system operator - have been developing a project for an interconnector between Britain and the Netherlands and announced in May 2007 that this link is to be constructed and operational by late 2010.
The ?600 million joint venture will support security of electricity supply in both markets and will allow BritNed's customers to participate in European markets and create open access for all.
BritNed will have a capacity of 1000MW and will be 260km long. The link will run beneath the North Sea between the Isle of Grain in Kent to Maasvlakte, near Rotterdam.
BritNed will transmit power in both directions, driven by price differentials and demand patterns between the two power markets. The link will facilitate competition and contribute to the European Commission's desire to for greater interconnection. It has been identified as a 'priority' project in the European power market.
BritNed will be a commerical, or 'non-socialised' interconnector, funded and operated independently from National Grid and TenneT's regulated businesses. Customers will open access to the capacity via a combination of 'implicit' auctions facilitated by APX, and short term 'explicit' auctions. This approach gives customers real choice about how they bid for capacity and ensures that Britned supports the ambitions for greater transpareny in the European energy markets.
=========== So thats 160 miles and 600M euros..£472M quid...at todays exchange rate. so a shade off £3M a mile for a Gigawatt.
Roughly equivalent in capital cost to about 1/2 to 1/3rd the cost of a nuclear or coal set.
Or a windfarm operating at peak capacity (which they don't, much)
