[2] The site, located on Burbo Flats in Liverpool bay (~7 km northwest 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 × 3 MW turbine wind farm, with monopile foundations on a site of approximately 10 km2 (3.9 sq mi).

[24] 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.

Samples within the turbine area showed sand followed by clay down to around 30m before weak mudstone was found.

Prestatyn, Wales) to an extension of the new Bodelwyddan 400 kV substation under construction for the Gwynt y Môr Offshore Wind Farm.

[41] DONG Energy (now Ørsted) sold half of the wind farm extension to KIRKBI A/S (Lego holding company) and Danish pension fund PKA for £660 million in February 2016.

[42] In early 2014, DONG Energy announced that the Vestas' V164 8.0 MW turbine was the preferred model for the development,[43] and made preliminary agreements to buy 32 units in August 2014.

[45] The nacelles are to be produced at the former Odense Steel Shipyard, while the blades are made at Vestas' Isle of Wight facilities.

[49] In January 2015 RXPE (Rongxin Power Engineering) was awarded the design and build contract for the Burbo 2 extension Dynamic Reactive Compensation electrical equipment (STATCOM);[48] and Bladt Industries and EEW obtained the contract to construct wind turbine foundations and structures, with transition pieces to be manufactured by Bladt/EEW jv Offshore Structures (Britain) Ltd. (former TAG Energy Solutions plant in Billingham, UK), and by Bladt at Aalborg (Denmark) with monopiles made at EEW's factory in Rostock (Germany).

In early 2016 DONG Energy acquired a lease on Cammell Laird's yard in Birkenhead to be used as a base during the construction of the wind farm.

[61] 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.
