Hornsea Project ThreeHornsea Project ThreeDONG Energy is proposing to develop a new offshore wind farm (Hornsea Project Three), in the North Sea, off the North Norfolk Coast. ​The proposed wind farm will be capable of generating up to 2,400 MW of electricity, enough to meet the average daily needs of well over 2 million homes.The Project team is exploring an offshore area of up to 696 km2, which is more than 17 times the size of Norwich, and over 120 km offshore, over three times the distance from Norwich to Cromer.






​DONG Energy 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 over 3,000 MW of operational capacity globally.

In August 2015, DONG Energy 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 Hornsea Project One is currently under construction after reaching Final Investment Decision in February 2016.

We are now exploring the potential to develop a third project in the zone, Hornsea Project Three Offshore Wind Farm, which is currently in the early pre-application stage for a DCO. For more information on how you can get involved, please see our section on Public Consultation.

Planning Process

​As a Nationally Significant Infrastructure Project (NSIP) , the Project must apply for a Development Consent Order (DCO) . Consents for the offshore wind farm, offshore and onshore cable route including substations will be included in the DCO.

In England and Wales, the DCO is examined by the Planning Inspectorate (PINS), who will consider a number of issues, including the impacts on the local area, and must be satisfied that we have undertaken sufficient pre-application consultation with local communities under consultation requirements contained in section 42 (statutory consultees) and section 47 (local communities) of the Planning Act 2008.

If the application is accepted, PINS will then coordinate the examination of our application with an independent Examining Authority panel, who will in turn make a recommendation to the Secretary of State (SoS) for Business, Energy and Industrial Strategy. The SoS will then review and comment on this before making a decision on whether to grant Development Consent.

Public Consultation

We at DONG Energy want to hear your views on our proposed Project.

Throughout this consultation period, we will do everything we can to make sure that everyone who may feel a direct or indirect impact from our proposed development, and wants to make their views known, has an opportunity to do so. We recognise that you and your community offer an extensive pool of local knowledge, and want to work with you to address any concerns you may have to help shape the Project as it develops.  

We recognise that effective consultation means balancing the tension between early engagement, when plans are fluid enough for you to influence their direction, and presenting proposals that are firm enough to allow you to comment effectively. For this reason, we plan to hold a minimum of two rounds of public consultation events.

We are committed to open, honest and inclusive engagement, and will support anyone who wishes to become involved, whether it be to share his or her views or simply find out more about the Project. We want to keep you informed throughout the consultation period and beyond, and will make sure that you receive proper feedback, so you know what views were expressed during the consultation, how they changed the plans for the project, and in instances where we did not make any changes, we will explain why this was the case.

Our first round of community consultation events took place in venues across Norfolk between October 31 - November 9. A short summary of all of the feedback received at these events is available here.

Hornsea Project Three is currently in the pre-application phase for a Development Consent Order, the major consent required to allow the development to proceed. The diagram below outlines the consultation process in the lead up to submission of our DCO application in 2018. Phase One (informal) consultation will take place until Q3 2017, before a second phase of consultation (Phase Two) on the Preliminary Environmental Information is conducted. There will be a minimum of two rounds of community consultation events, one per phase.

If this is successful, construction of the offshore wind farm is anticipated to take place between 2022 and 2025*.

Project Manager's Blog

As the project progresses we thought it would be nice to share some of the stories behind the scenes so that you can see what goes into planning and building a huge infrastructure project such as this. Each month, we'll bring you an update from a member of the team. Read our stories below.



Happy New Year from all at Hornsea Project Three…Happy New Year from all at Hornsea Project Three…

​This month's blog comes from Stuart, the Project Development Manager, who gives an update on the stages of the project and what to expect next…

We’re still in the very early stages of developing Hornsea Project Three, and are still scoping out the details of what the project will look like and where things will potentially go both onshore and offshore. We’re building up to apply for a Development Consent Order (DCO), the main consent application that is issued, which we hope to be able to submit in 2018. This is something that all Nationally Significant Infrastructure Projects (NSIPs) have to apply for and is basically the means by which much needed energy infrastructure gains permission to be built. Our application will be examined and the final decision given by the Secretary of State for Business, Energy and Industrial Strategy (BEIS).

During this pre-application stage we consider how best to implement the project, including everything from where cables will be buried onshore to what the actual layout of the windfarm will potentially look like.

In order to minimise disturbance to the community including landowners, fishermen and residents, we’re trying to get people’s views as early as possible in the project development, so these can be taken into account as we refine our plans. We set out how we plan to consult with communities in our Statement of Community Consultation and we’ve already held a series of public Community Consultation events last year, which I attended. I can state both personally and on behalf of the project, it was really great to meet local people and understand how the project might affect them. One of the key elements of these events is understanding concerns, hearing about local issues we may not previously have been aware of and taking these away to consider how we can amend our proposal to reduce impacts and concerns where possible. The feedback from these events are available here.

I can’t emphasize enough the importance of working with the community at this stage. We will listen to your comments and where possible integrate these. I want to stress that nothing has been decided yet, so if people do have concerns now is the time to get in touch and let us know.

We’ve just announced another round of events in early March 2017 so I hope again to meet many people there and talk about the project with them and how this has changed since the last series of events in late 2016. In the meantime if you want to get in touch, there are plenty of ways to do so and we welcome any questions or comments on the project.

Until next time…
