Our offshore wind farms in the UK

12 operational
3 in development

From the world's first to the world's biggest

Since pioneering the world’s first offshore wind farm in 1991, we have established ourselves as the unrivalled leader within global offshore wind power production. We develop, construct, own and operate offshore wind farms in Denmark, Germany, Netherlands, UK, Taiwan and the USA.

With 7.5 GW installed and over 30 years of experience, it is our ambition is to have installed 30GW of offshore wind worldwide by 2030.

We are also the UK leader in offshore wind with 5.6GW operational. Our 12 UK offshore wind farms produce enough electricity to power over 7 million homes.

  • Barrow

    Electricity generated by the wind farm is delivered to the National Grid at a substation in Heysham, Lancashire via 27km of buried subsea transmission and onshore cables.

    Construction and commissioning work was completed in June 2006, a little over a year after offshore work got underway in the East Irish Sea. First power was generated in March 2006. Ørsted's team of technicians and project staff operate the wind farm from an operations and maintenance (O&M) base in Barrow-in-Furness.

  • Hornsea 1

    Hornsea 1 produces enough energy to power well over one million UK homes. With a capacity of 1.2 gigawatts (GW), the project was the world's first offshore wind farm to exceed 1 GW in capacity. Hornsea 1 held the title of the world's largest offshore wind farm until its sister project, Hornsea 2 took the crown in 2022.

    Located off the Yorkshire coast, Hornsea 1 spans a huge area of approximately 407 square kilometres, which is over five times the size of the city of Hull.

    The offshore wind farm has 174 wind turbines of 7 megawatts (MW). Each one is 190 metres tall – larger than the Gherkin building in London.

  • Hornsea 2
    • 165 turbines delivering 1.3GW of renewable electricity
    • The wind farms covers an area of 462 sq. km – equal to 31 Lake Windermeres
    • Each turbine blade is 81m long and the blade tip is more than 200m above sea level
    • One revolution of the turbine blades can power an average UK home for 24 hours

    Hornsea Two is located  89km off the Yorkshire coast, adjacent to sister project Hornsea 1.  The 1.3GW project comprises 165 wind turbines which will help power over 1.4 million UK homes with low-cost renewable energy. 

    The project has played a key role in the ongoing development of a larger and sustainably competitive UK supply chain to support the next phase of the UK’s offshore wind success story.

    The offshore wind farm will make an important contribution towards the UK goal for renewable electricity generation and to achieve the UK's energy security and carbon reduction objectives. Hornsea 2 is the continuation of our strong commitment to the UK and further investment into the UK offshore wind pipeline.

    Hornsea 2 became fully operational on 31 August 2022

Wind farms in development

We currently have three offshore wind farms in development. Read more about the latest activities for these projects.

  • Hornsea Three

    Hornsea Three will be located in the North Sea, approximately 121 km off the Norfolk coast and 160 km off the Yorkshire coast.

    The wind farm will be capable of generating at least 2.85 GW of green electricity, enough to meet the average daily needs of 3 million homes.

    On 31 December 2020, The Secretary of State for the Department for Business, Energy and Industrial Strategy granted consent for the Hornsea Three offshore wind farm.

    Learn more about the project background, progress and details of the proposed area.


  • Hornsea Four

    Hornsea Four is an offshore wind farm which Ørsted is proposing to develop in the North Sea, approximately 65km off the Yorkshire Coast.

    In August 2015, we acquired the rights to develop the Hornsea zone from SMart Wind Ltd, who were originally awarded the zone in The Crown Estate Round 3 bid process.

    To date, Hornsea One is in operation, Hornsea Two is currently under construction and Hornsea Three received consent from the The Secretary of State for the Department for Business, Energy and Industrial Strategy on the 31 December 2020.

    We are now exploring the potential to develop a fourth project in the zone, Hornsea Four. The Project is currently in the pre-application process where thorough consultation on the project plans and proposals will take place in parallel with the Environmental Impact Assessment (EIA) process, resulting in an application for a DCO. 

    It is important to note that the Project is still at an early stage in the development process and is considering the options available to it. The planning process it is required to follow to apply for a DCO is a complex and thorough one (stipulated by the 2008 Planning Act, as the Project will be a Nationally Significant Infrastructure Project (NSIP) and capable of generating enough electricity to power hundreds of thousands of UK homes).

  • Isle of Man
    Green energy pioneers
    The Isle of Man’s renewable energy transition shows the big part small Island nations can play in tackling climate change, writes John Galloway, Ørsted Development Director for the Isle of Man Offshore Wind Farm.

    We are investigating an area in the Territorial Seas of the Isle of Man, to the east of the island. The project is at an early stage of development, and as such its final layout and size are not known. Subject to our investigations, and the outcome of future consenting processes, the windfarm could generate renewable electricity to support the Isle of Man’s own Net Zero, economic development and sustainability ambitions. While the number of wind turbine generators and their sizes are not yet known, this will be considered during the planning and consenting process.

    About the project

    Ørsted was awarded "Preferred Bidder" status in November 2014, following a tender process conducted by the Isle of Man Government earlier in the year.

    Ørsted has now signed an Agreement for Lease (AfL) with the Isle of Man Government.  This AfL gives Ørsted the right to investigate an agreed area within the Isle of Man Territorial Seas, located approximately 6-12 nautical miles off the east coast of the island, to determine its suitability for an offshore wind farm.

    It will take a number of years to complete these investigations, after which there will be an option to execute a lease with the Isle of Man Government for the seabed over the lifetime of the wind farm, if conditions are suitable.

    Planning Consent will be needed before a lease is signed with the Isle of Man Government and if conditions are not suitable for an offshore wind farm Ørsted will hand the site back to the Isle of Man Government.

    Subject to the specific findings of the investigations throughout the development stage, construction activities would be likely to take place post-2025.

    Project Description

    The site under investigation for the proposed wind farm is located within the Territorial Seas of the Isle of Man, to the east of the island.

    The project is at an early stage of development, and as such its final layout and size are not known.  It is important to note that the final size of the windfarm will be less than the area currently earmarked by the AfL for investigation. 

    Environmental Assessment

    Ørsted will be producing an Environmental Statement to support the applications for  Marine Infrastructure Licence and other consents needed for the export cable installation inside and outside of Isle of Man waters.  Work has started on the production of an EIA Scoping Report for the potential offshore works.

    Other information

    • Ørsted awarded Preferred bidder status
    • Signed an Agreement for lease November 2015
    • Now investigating territory 6-12 miles off the east coast of the Isle of Man
    • Pending investigation, any potential wind farm could generate 800MW or more.
