About the project

Hornsea Three offshore wind farm could meet the average daily needs of well over 2 million UK homes


Hornsea Three will be located in the North Sea, approximately 120 km off the Norfolk coast and 160 km off the Yorkshire coast.

Up to 231 offshore wind turbines will be located within a 696 km2 area.

Power output
The wind farm will be capable of generating at least 2,400 MW of green electricity, enough to meet the average daily needs of well over 2 million homes.

Project Background

Ørsted is one of the leading energy groups in Northern Europe, headquartered in Denmark, with UK head offices in Central London and numerous site offices around the UK. We are the world leader in developing, constructing and operating offshore wind farms, with 6.8GW of operational capacity globally.

In August 2015, Ørsted 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 and Hornsea Two have both received planning consent, with Hornsea One now operational and Hornsea Two currently under construction.

On 14 May 2018, we submitted a Development Consent Order (DCO) application for a  third project in the zone, Hornsea Project Three Offshore Wind Farm.

The application was accepted by the Planning Inspectorate in June 2018 and was granted consent by the Secretary of State for the Department for Business, Energy and Industrial Strategy on 31 December 2020.

Ørsted would like to thank Shoney Wind Ltd for sharing its specialist knowledge and innovative concepts for purpose built, modular, adaptable, and relocatable artificial kittiwake towers which helped inform Ørsted’s Hornsea Three Kittiwake Compensation thinking.  The Shoney Wind designs take account of environmental factors such as wind direction and sun exposure and include internal access to breeding kittiwakes via a stairwell and internal cabin. The designs facilitate direct access to the birds and enable ornithologists to undertake comprehensive monitoring of birds, their nests and their young. Shoney Wind designs include supplementary feeding mechanisms successfully pioneered by Shoney Wind’s collaborator, the Institute for Seabird Research and Conservation of Anchorage, Alaska.

We will resume newsletter production prior to construction works commencing.
