The Burbo Bank Offshore Wind Farm lies on the Burbo Flats in Liverpool Bay and has a total capacity of 348 MW, combining the original 90 MW farm (2007) and a 258 MW extension (2017). It was first developed by SeaScape Energy and later acquired by Ørsted (then DONG Energy). The original site used 25 Siemens 3.6 MW turbines, while the extension introduced 32 Vestas 8 MW turbines, among the first of their kind worldwide.

Construction of the first phase began in 2006, with MT Højgaard, Ramboll, and Siemens as key contractors. Power is exported at 132 kV, supplying around 80,000 homes. The farm cost around €181 million, with a levelised cost of £87/MWh.

The extension, approved in 2014 and completed in 2017, used larger turbines and new export cables supplied by ABB and Nexans. Built with support from investors KIRKBI A/S (LEGO Group) and PKA, it marked a major step in turbine scale and efficiency. The combined project produces enough power for over 300,000 homes, symbolising the evolution of offshore wind technology in the UK.
