Balfour Beatty and Skanska among six bidders for West of Duddon Sands offshore wind farm

Ofgem E-Serve has announced that six firms are in line to bid for a scheme to own and operate the £311 million high-voltage transmission link for the West of Duddon Sands offshore wind farm.

The winning bidder will own and operate the link for the next 20 years. The next stage of the process is to select a shortlist of bidders who will go through to the final bid stage.



The longlist of bidders that have pre-qualified before tender stage comprises:

  • Balfour Beatty Equitix Consortium (a bidder group comprising Balfour Beatty Investment and Equitix)
  • Blue Transmission (a bidder group comprising Macquarie Capital Group, Barclays Infrastructure Funds Management, Mitsubishi Corporation and Frontier Power)
  • John Laing Investments
  • National Grid Offshore
  • Skanska (a bidder group comprising Skanska Construction UK and Skanska Infrastructure Investment UK)
  • Transmission Capital Partners (a bidder group comprising Transmission Capital Partners Limited Partnership and International Public Partnerships)


The wind farm is located in the East Irish Sea approximately 14 km from the nearest coast on Walney Island, Cumbria. It is situated in the vicinity of nearby wind farms: Barrow, Ormonde and Walney.

The project will comprise 108 wind turbines with a total installed capacity of 389 MW and ensure clean renewable energy for more than 300,000 UK households.

Ofgem E-Serve managing director Robert Hull said: “The strong interest in competing for the West of Duddon Sands transmission assets is further proof that the offshore regime is successfully encouraging investment, attracting new players and ensuring competition in the offshore transmission sector.”

The next stage is tender round 3, which is expected to commence later in 2013.
