Denmark-based Dong Energy holds a 50% stake in the project, while Japan’s Marubeni and the UK Green Investment Bank own the remaining interest equally.
Located 8km off the Yorkshire Coast, north of Hull, the wind farm features 35 Siemens 6MW turbines that generate enough energy for over 150,000 homes in the UK.
The wind farm, which will be operated and maintained from the Royal Dock in Grimsby, will deliver green energy to the UK grid for the estimated life of about 25 years.
Dong said cables bring the electricity ashore on the Holderness Coast north of Withernsea and into the national grid at the onshore substation on Staithes Road, Hedon outside Hull.
The project will help in meeting the UK’s commitment of reducing CO2 emissions and contribute in achieving the country’s targets of generating electricity from renewable energy schemes.
Dong Energy chief executive Henrik Poulsen said: "Westermost Rough is the latest wind farm in our portfolio of wind farms with a total installed capacity of over 3,000 MW – more than half in the UK."
Siemens wind and renewables division CEO of offshore Michael Hannibal said: "This is the first time Siemens has installed the 6 MW direct drive turbine with a 154 meter diameter rotor on a commercial-scale project.
"The Westermost Rough project reinforces our wide-ranging experience in offshore wind and is leading the way to bring the costs of offshore wind energy down."
