About the project

Norfolk Boreas is the second of our two proposals for offshore wind farms off the Norfolk coast, and is the sister project to Norfolk Vanguard. Both are named after ships commanded by Admiral Lord Nelson in the late 1700s. 


The development area for the 1.8GW Norfolk Boreas Offshore Wind Farm is located adjacent to the Norfolk Vanguard project area, it covers 725km2 and is approximately 72km from shore at its nearest point.

The scale of Norfolk Boreas means it is classed as a Nationally Significant Infrastructure Project (NSIP) under the Planning Act 2008. There is a very clear process that we will follow, with many opportunities for you to get involved. You can find out more about the Consultation and Planning processes applicable to Norfolk Boreas on the relevant pages of this project website.

The timeline for Norfolk Boreas is approximately one year behind Norfolk Vanguard, and there are significant advantages to developing two co-located, major projects just 12 months apart, not least in that construction can be coordinated and overall impacts reduced.

The aim is to share a common route for the underground electrical connection from landfall at Happisburgh to the National Grid substation near Necton. This approach means just one trenching operation for both projects, significantly reducing potential disturbance along the onshore cable route.

There are socio-economic advantages too - enabling cost efficiencies which will benefit the UK consumer, and also supply chain advantages for Norfolk and East of England, meaning that businesses and stakeholders can plan to take advantage of inward investment over the coming years.


Norfolk projects similarities and advantages


We held the first round of Public Information Days for Norfolk Boreas in March and April 2017. In our communications we outlined the similarities, differences and opportunities associated with the phased approach to the development of Norfolk Boreas and Norfolk Vanguard.

The high quality feedback received through this process from discussions with local stakeholders has helped to shape the design of Norfolk Boreas and following months of  further assessment and refinement of the proposals, we are now ready to present the Preliminary Environmental Information Report (PEIR) . The full suite of project documents is available to view on the Documents page of this website.  

 A period of formal (statutory) consultation will begin on 7th November and will run until 9th December 2018. For more information on the consultation process and having your say in our proposals, please refer to the Planning  & Consultation  pages of the website.


Project Scenarios

It is important to note that the Norfolk Boreas DCO application will consider two scenarios. Scenario 1 is where both Norfolk Vanguard and Norfolk Boreas are delivered and Scenario 2 is where only Norfolk Boreas is delivered. 

Scenario 1 - Norfolk Vanguard and Norfolk Boreas – Norfolk Vanguard proceeds to construction, and installs ducts and carries out other shared enabling works to benefit Norfolk Boreas. This scenario is optimal and the most probable outcome. Please click below to use the detailed interactive mapping tool.

Scenario 2 - Norfolk Boreas only – Norfolk Vanguard does not proceed to construction and Norfolk Boreas proceeds alone. The Norfolk Boreas EIA will also consider associated constraints and opportunities, under Scenario 2 and undertakes all works required as an independent project. Please click below to use the detailed interactive mapping tool.

You’ll find more information about the two scenarios in the Consultation Summary Document and in the PEIR documentation.

Project Background

In 2010, as part of a joint venture with ScottishPower Renewables, Vattenfall acquired rights from The Crown Estate to develop the East Anglia Offshore Wind Farm Zone. In February 2016 the joint venture between Vattenfall and ScottishPower Renewables was dissolved and replaced with individual 'Project Specific Agreements' from The Crown Estate for each developer to progress their interests independently. These new working arrangements are a more effective way to secure the potential of the Zone and deliver low cost, low carbon power to the UK customer.

We have now started developing plans for the northern half of the zone, which is split into two development areas: Norfolk Boreas and Norfolk Vanguard.  Combined, the two projects will have an operating capacity up to 3.6GW, with the potential to provide power to up to 2.6million [1] UK homes.
