Cable firm Nexans has secured a contract worth €100m (£90m) to manufacture and supply the high-voltage subsea power export cables that will connect the London Array to the UK grid.
The deal comprises the supply of four 150kV XLPE submarine power cables, each 53km to 54km in length, with three copper core conductors with a cross-section of 630mm2 for the main length and 800mm at each cable end.
The contract was awarded by a consortium consisting of DONG Energy, E.ON and Masdar, which is currently building the world’s largest offshore wind farm in the Thames Estuary.
The London Array wind farm is being installed on a 233km2 site located around 20km off the UK coast. The first phase of construction involves installing 175 turbines, to be completed and generating 630MW by 2012. The second phase will increase capacity to 1,000MW, enough power for around 750,000 homes.
Nexans is scheduled to deliver two of the cables in 2011 and two in 2012, from its factory in Halden. The cables will also incorporate fibre-optic elements manufactured at its factory in Rognan, Norway. The contract includes cable accessories such as repair joints and terminations.
Frédéric Vincent, Nexans chief executive, said: ‘World-leading schemes such as London Array demonstrate why the UK is currently regarded as one of the pace-setters in offshore wind energy, and we are very proud to be cooperating in this prestigious project with some of the key developers in this dynamic market.’
