The Burbo Bank Offshore Wind Farm is an 90MW offshore wind farm located on the Burbo Flats in Liverpool Bay on the west coast of the UK in the Irish Sea.

The wind farm was developed in the 2000s by SeaScape Energy, which was acquired by Dong Energy in 2005. A 25 turbine installation using Siemens Wind Power 3.6MW turbines was constructed from 2005, and official opened in 2007.

In 2009 planning began for a potential ~250MW extension; Burbo Bank Extension

History and design[edit]

Burbo Bank Wind Farm[edit]

In September 2002 SeaGreen Energy ( Zilkha Renewable Energy, enXco A/S, Wind Prospect Ltd. joint venture.[1]) submitted an application to develop a Round 1 offshore wind farm site.[2] The site, located on Burbo Flats in Liverpool bay (~7 km norwest of Wirral and ~6 km west of the Sefton coastline) was selected due to shallow water depths (0.5 to 8m at low tide), high wind speeds ~7 m/s (23 ft/s), and a generally favourable location including proximity to an electrical grid connection. Initial expectations were for a 30 3MW turbine wind farm, with monopile foundations on a site of approximately 10 km2 (3.9 sq mi). An electrical connection to the mainland grid was to be made by a seabed cable running southeast to Wirral, followed by a ~3.5 km underground cable to a substation at Wallasey.[3] SeaScape received a capital grant of £10 million in 2003 to aid development of the project.[4]

In 2003 EDF subsidiary enXCo bought the interests of Wind Prospect in the project,[5] the project became a joint venture between Elsam and EDF Energies Nouvelles in 2004 with Elsam taking 50% of the projecty.[6] In September 2005 Siemens Wind Power was selected as the turbine supplier, with 25 3.6MW turbines ordered at a cost of over €90 million.[7][8] In December 2005 Dong Energy became sole owner of the project.[9]

Construction began in June 2006.[2] Contractor for the foundation installation was MT Højgaard:[10] the foundation design was by Ramboll,[11] Smulders supplied the WTG foundations,[12] turbine towers by Bladt Industries,[13] monopiles and transition pieces were from Sif;[14] piling was done by Menck,[15] with Mammoet Van Oord supplying lifting barge platform Jumping Jack.[2][16][17]

The contractor for the substation was EDF Energy Contracting, cable installation was by McNicholas Construction Services Ltd. (onshore) and Submarine Cable & Pipe (offshore), with cables supplied by ABB Group.[18] Inter turbine and grid connection to the substation was at 33kV, with voltage step up to 132kV at the substation for grid connection.[19]

The facility began generating power in July 2007,[2][20] and the wind farm was officially inaugurated on 18 October 2007,[21] and the facility was commercially operational by the end of 2007;[18] the capital cost of developing the wind farm was €181 million.[22]

Between 2008 and 2010, the capacity factor was between 32 to 35%.[23] In 2009 the whole wind farm was put out of action for 4 weeks due to a failure in the underground electrical cable connecting to the National Grid.[24] During summer 2010 Siemens decided to change the blade bearings on all 25 turbines as a pre-emptive measure after corrosion was found in blade bearings found on other sites.[25]

At the end of the windfarm's operational life (25 years) the wind farm will be decommissioned.[26]

Burbo Bank Extension[edit]

In 2009 the Crown Estate announced that wind farm operators could apply for extensions to their Round 1 or Round 2 offshore wind farms; Dong Energy identified Burbo Bank as a potential site and began consultation on a ~90 km2 (35 sq mi) extension westwards of the original wind farm. Between 2009 and 2010 the area of the site was reduced to the north increase clearance from the shipping lanes to the Port of Liverpool; to the south and to the west, reducing potential impact on recreational sailing activities and on certain species of sea bird, and due to potential conflicts with ship anchoring sites; also reducing the visual impact from land. In April 2010 the Crown Estate awarded an area of 40 km2 (15 sq mi) for lease.[27]

The initial cable export route and grid connection identified was one making landfall near to the existing Burbo Bank land connection, and connected to a 275kV substation in Birkenhead; subsequently a potential grid connection at the 400kV Deeside substation (near Deeside Power Station, Wales) was identified; and later a connection with landfall at Ffrith Beach, (nr. Prestatyn, Wales) to an extension of the new Bodelwyddan 400kV substation under construction for the Gwynt y Môr Offshore Wind Farm. In 2011 the developer reached an agreement with the National Grid to use to a connnection near the Bodelwyddan substation.[28]

The planned export cable route crossed a number of pre-existing cables and pipelines: a set of pipelines related to the Liverpool Bay oil and gas field, connecting the Douglas Complex to landfall were crossed in the Mid-Hoyle channel[29] the export cable route also ran close to the North Hoyle Offshore Wind Farm export cable;[30] and crossed the 500MW East–West Interconnector, as well as the planned route of the 2000MW Western HVDC Link.[31]

Initial expectations were for construction to start in early 2015, and be complete by early 2017, subject to final specifications;[32] neither foundation nor turbine type was specified,[33] an offshore substation to step up the inter turbine voltage (either 33 or 66kV) to an export voltage of either 132 or 275kV, connection to the National Grid would be made at 400kV, stepped up at an onshore substation at Bodelwyddan.[34]

In 2014 Dong Energy announced that the Vestas' V164 8.0MW turbine was the preferred model for the development,[35] and made preliminary agreements to buy 32 units in Aug 2014.[36]


After around 20–25 years of operation the wind farm would be expected to be decommissioned, including removal off all offshore components above seabed level.[37]
