A joint venture (JV) of Dong Energy and ScottishPower Renewables has agreed to sell transmission assets worth £269m at the €2bn West of Duddon Sands offshore wind farm in the UK.

WoDS Transmission, which is owned equally by Macquarie Corporate Holdings and 3i Infrastructure, will buy the assets that include the onshore substation, export cables and offshore substation.

Dong said the sale has been executed as per the Offshore Transmission Owner regime. WoDS Transmission has selected the wind farm’s JV partners to deliver operations and maintenance services to the transmission link.

The 389MW West of Duddon Sands wind farm was opened in October last year. It is situated about 20km off the Barrow-in-Furness coastline in North West England.

The wind farm, which is spread across an area of 67km2, features 108 Siemens 3.6MW turbines. It will generate enough energy for about 280,000 homes per year.

More than 200km of undersea cables were installed and a £50m offshore wind terminal was built at Belfast Harbour as part of the project.

The electricity generated from the project will be initially connected to an offshore substation.

The voltage from the turbines is increased and two export cables will then take the energy ashore to the onshore substation at Heysham, where the wind farm is linked to the UK national grid.
