The energy distributor has released three frameworks to the market to deliver plans for major power line links and high voltage direct current converter stations to hook up the offshore wind farms.
The core construction framework will be worth £12.8bn over 8 years and covers major works and civils for construction of converter stations and installation of UHV cable. This programme will involve at least 15 HVDC projects, with the scope of some still to be agreed.
