With a capacity of 1.2 GW, Hornsea Project One will be the world's first offshore wind farm to exceed 1 GW in capacity and will become – by a considerable margin – the world's largest offshore wind farm.
Once completed, Hornsea Project One will be able to meet the electricity needs of well over 1 million UK homes. It will be located 120 km off the Yorkshire coast – further than the distance from Leeds to Liverpool. The project will span a huge area of approximately 407 square kilometres, and use 7 MW wind turbines, each one 190 m tall.
Siemens has been named preferred supplier for the 7 MW wind turbines and the new Siemens turbine production facilities in Hull will support the project. A £25 million contract has also been awarded to UK infrastructure company Balfour Beatty for the construction of the onshore substation, underlining DONG Energy's positive impact on the UK supply chain.
