Offshore Wind Farms in Construction

We currently have three wind farms in construction. Find out about our latest projects and access important information on their websites by clicking the Learn More buttons below.



Burbo Bank Extension

This wind farm will produce enough energy to power over 230,000 homes.


Burbo Bank Extension offshore wind farm is currently under construction in the Irish Sea. The project is an extension to the current Burbo Bank offshore wind farm and once completed, will comprise 32 turbines with a combined capacity of 258MW.

The project will be situated on the Burbo Flats in Liverpool Bay, at the entrance to the River Mersey, approximately 7km (4.3 miles) north of the North Wirral Coast, and the project's total area will be 40km2.



Hornsea Project One

This wind farm will be the largest offshore wind farm in the world. Once completed, it will produce enough energy to power over 1 million homes.


With a capacity of 1.2 gigawatts (GW), Hornsea Project One will be the world's first offshore wind farm to exceed 1 GW in capacity.


Located off the Yorkshire coast, Hornsea Project One will span a huge area of approximately 407 square kilometres, which is over five times the size of the city of Hull. The offshore wind farm will use 7 megawatt (MW) wind turbines, with each one 190 metres tall – larger than the Gherkin building in London.




Race Bank

This wind farm could generate enough electricity to power over 500,000 UK homes annually.


In December 2013, DONG Energy acquired the Race Bank Offshore Wind Farm from Centrica Plc. The Project, having already secured development consent, will be located approximately 16.8 miles off Blakeney Point on the North Norfolk coast and 17.4 miles off the Lincolnshire coast at Chapel St Leonards. The offshore array will cover an area of approximately 29 square miles.


Export cables for Race Bank will come to shore east of the mouth of the River Nene and approximately 3.7 miles north-northeast of Sutton Bridge. The cables will run in a southerly direction to the connection point at the existing Walpole substation. The approximate length of the onshore section of cable is 6.8 miles.


The project has a potential maximum capacity of up to 580MW and could also realise a potential annual carbon saving of over 830,000 tonnes of CO2.

Walney Extension

This wind farm will power over 590,000 UK homes.


Walney Extension offshore wind farm is currently in the construction phase. Located in the Irish Sea, approximately 19 kilometres off the coast of Cumbria, the project is an extension to the existing Walney offshore wind farm. This project will have a generation capacity of 659 MW.


Walney Extension is expected to be fully commissioned in 2018, at which time it will be the biggest offshore wind farm in the world, surpassing the 630MW London Array Offshore Wind Farm which was commissioned in 2014 by DONG Energy and its partners.
