With a capacity of 1.2 gigawatt (GW), Hornsea will on completion be the world’s first offshore wind farm to exceed 1,000 MW in capacity and by a large margin become the world’s largest offshore wind farm. It will be able to meet the electricity needs of well over one million UK homes.
Hornsea is located 120km off the Yorkshire coast and covers approximately 407 square kilometers. DONG Energy has chosen the Siemens 7.0MW wind turbine for Hornsea. DONG Energy is the sole owner of Hornsea after acquiring the 66.66% ownership share from Smart Wind in February 2015. DONG Energy also have the project rights to the Hornsea Project Two and Three, which have the potential of further 3 GW offshore wind power capacity in total.
Hornsea was granted a Final Investment Decision Enabling contract (Contract for Difference) by the UK Government in April 2014 and will receive a fixed tariff for the first 15 years of production. The wind farm is expected to be fully commissioned in 2020.
Hornsea will surpass Walney Extension, which had a final investment decision in October 2015, as the world’s largest offshore wind farm. Walney Extension will have a capacity of 660 MW so Hornsea is almost double the size.
