Operational Offshore Wind Farms


We fully or partly own eight operational wind farms in the UK. Learn more about each project below.

 

 

 

 

 

Barrow Barrow

Barrow produces enough electricity to power over 80,000 UK homes annually.

Number of turbines: 30
Generation capacity: 90MW
Commercial operation: 2006
Owner of the project: DONG Energy

Barrow Offshore Wind Farm is located in the East Irish Sea approximately 7km south west of Walney Island, near Barrow-in-Furness.

Electricity generated by the wind farm is delivered to the National Grid at a substation in Heysham, Lancashire via 27km of buried subsea transmission and onshore cables.

Construction and commissioning work was completed in June 2006, a little over a year after offshore work got underway in the East Irish Sea. First power was generated in March 2006. DONG Energy’s team of technicians and project staff operate the wind farm from an operations and maintenance (O&M) base in Barrow-in-Furness.

Gunfleet SandsGunfleet Sands

Gunfleet Sands produces enough electricity to power over 150,000 UK homes annually.

Number of turbines: 48
Generation capacity: 173MW
Commercial operation: 2010
Ownership of the project: DONG Energy (50.1%), Marubeni Corporation (24.95%) and DBJ (24.95%)

Gunfleet Sands Offshore Wind Farm is located approximately 7km south-east of Clacton-on-Sea, Essex.

The project consists of two phases, Gunfleet Sands 1 with 30 turbines and Gunfleet Sands 2 with 18 turbines. The total area covered is 17.5km2.

The capacity of each turbine is 3.6 MW, giving a total capacity of the Gunfleet Sands project of 173 MW. The total area of the phase 1 development is 10km2 and 7.5km2 for phase 2.

The wind farm was constructed by DONG Energy, and is owned by DONG Energy (50.1%), Marubeni (24.95%) and DBJ (24.95%)

Demonstration Project

In 2013, a demonstration project was completed at Gunfleet sands to test two of Siemens' 6MW. At the time these were the biggest offshore wind turbines in the world. They were subsequently deployed at Westermost Rough offshore wind farm, inaugurated  July 2015, and more offshore wind farms besides. They are still the biggest commericially deployed and currently operational turbines.

Operation & Maintenance

Gunfleet Sands Offshore Wind Farm is operated and maintained from the town of Brightlingsea only 35 minutes away by vessel.

DONG Energy has built their operation base in Brightlingsea and recruit staff locally, thus committing to a long-term relationship with Brightlingsea.

LincsLincs

​Lincs produces enough electricity to power over 240,000 UK homes annually.

Number of turbines: 75
Generation capacity: 270MW
Commercial operation: 2012
Owner of the project: DONG Energy (25%), Centrica (50%), and Siemens Project Ventures (SPV) (25%)

Lincs is located 8km off the east coast, near Skegness in Lincolnshire.

In 2009, DONG Energy acquired 25% of the 270MW Lincs offshore wind farm from Centrica.

Construction on the wind farm began in 2010, and it was officially opened by the Deputy Prime Minister Nick Clegg, in August 2013.

London ArrayLondon Array

London Array produces enough electricity to power over 560,000 UK homes annually.

Number of turbines: 175
Generation capacity: 630MW
Commercial operation: 2012
Owner of the project: DONG Energy (25%), E.ON (30%), Masdar (20%), Caisse de depot du placement du Quebec (25%)

London Array is 20km off the east coast of Britain in the Thames Estuary. Approximately 10 kilometres further towards land are 48 turbines, which together make up Gunfleet Sands.

Since 2003 DONG Energy has been involved in the development of the world’s current largest wind farm, London Array, located in the outer Thames Estuary.

WalneyWalney

​Walney produces enough electricity to power over 325,000 UK homes.

Number of turbines: 102
Generation capacity: 367 MW
Commercial operation: 2012
Owner of the project: DONG Energy (50.1%), PGGM and Ampère Equity Fund (24.8%) and SSE (25.1%)

The Walney Offshore Wind Farm is located approximately 15km from the coastline of Walney Island in a north west to south-easterly direction covering an area of approximately 73 km2.

The Walney Offshore Wind Farm consists of Walney 1 and Walney 2 each comprising 51 wind turbines with a total capacity of 367 MW.

In May 2010 the 750 MW capacity Walney Extension was awarded. The application for consent was accepted by the Planning Inspectorate in July 2013.

Westermost RoughWestermost Rough Westermost Rough produces enough electricity to power over 180,000 UK homes annually.

Number of turbines: 35
Generation capacity: 210 MW
Commercial operation: 2015
Owner of the project: DONG Energy (50%), Marubeni Corporation (25%), UK Green Investment Bank (25%)

The offshore wind farm is situated 8km off the Yorkshire Coast, north of Hull.

The project marks the first commercial deployment of the Siemens 6MW turbine with a 154m rotor span. The 35 turbines are 177m tall from sea level to the highest reach of the blade tips, which is taller than the Humber Bridge.

Operations & Maintenance

Following commercial completion of Westermost Rough in September 2015, the operations and maintenance team are based out of facilities at the Royal Dock in Grimsby where they will manage the upkeep of the project for its 25 year lifetime.

Construction of the new offices and warehouse began in January 2014 and was completed at the end of the same year. Around 100 employees are based at the Grimsby site offices, which also has new pontoon access for three crew transfer vessels.

West of Duddon SandsWest of Duddon Sands

West of Duddon sands produces enough electricity to power over 345,000 UK homes annually.   

Number of turbines: 108
Generation capacity: 389MW
Commercial operation: 2014
Owner of the project: DONG Energy

The West of Duddon Sands Offshore Wind Farm is located in the East Irish Sea approximately 14km from the nearest coast on Walney Island, Cumbria. It is situated in the vicinity of nearby wind farms: Barrow, Ormonde and Walney.

The wind farm has an attractive offshore location with excellent wind resources, favourable water depths and grid access relatively close to the shore. The short onshore distance to the grid makes this area particularly suitable for development, construction and operation of an offshore wind farm.

In addition to the site's windy location, the wave and tidal conditions in the East Irish Sea are complex with a tidal difference of 10.2m.

West of Duddon Sands was officially opened by Secretary of State for Energy and Climate Change Ed Davey in October 2014. The construction work included installation of foundations, wind turbines, export and array cables, offshore and onshore substations, grid connection and O&M facilities.
