About the project

Creating a world that runs entirely on green energy

Project facts:

Location: Ørsted is proposing to develop Hornsea Project Four, 65km (at its closest point) off the Yorkshire Coast.

Size: The project team is exploring an offshore area of up to 846km2


Ørsted is a renewable energy company that takes tangible action to create a world that runs entirely on green energy.

With eleven operational UK offshore wind farms and another two under construction, we are a substantial investor in the UK. We are committed for the long-term, both to leading the change to green energy and to investing in the communities where we work.

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 Project One and Hornsea Project Two have both received planning consent and are under construction, while Hornsea Project Three has submitted an application for a consent (a Development Consents Order – DCO).

We are now exploring the potential to develop a fourth project in the zone, Hornsea Project Four. The Project is 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).

The planning process is very much consultation focused and we as the developer will provide more information on the Project and plans for its development to then allow you time to comment on our preliminary plans.

Your views and input on Hornsea Four are important to us and will help us to identify key areas of concern for the Project which can then be incorporated into the final design where possible.
