The Vestas V164-8MW is a three bladed offshore wind turbine, produced by Vestas, with a world-record 8 megawatt nameplate capacity. The first prototype unit was installed in northern Denmark in January 2014,[1] and the first industrial units are scheduled for installation in 2016 off the coast of the UK.[2]

As of 2012, this offshore turbine has the biggest projected installed capacity, diameter of rotor 164 metres (538 ft) and swept area 21,124 square metres (227,380 sq ft).[3][4] The economical background for development of this model of wind turbine is to reduce operations and maintenance costs by enabling customers to run fewer, larger turbines.[3]

Originally called the Vestas V164-7.0MW, at 7.0 MW, the output was increased to 8.0 MW.[5]

Starting November 2013, a prototype was installed at Østerild test station. The bottom tower sections weighs over 200 tonnes and is 24 metres long and 7 metres in diameter. The nacelle weighs 390 tonnes. The turbine weighs 1,300 tonnes and the foundation weighs 4,000 tonnes. The total height is 220 metres.[6] It became operational in January 2014.[7] It produced a record 192 MWh in 24 hours due to favourable winds.[8] The model was shifted from prototype to production in 2014, when DONG Energy ordered 32 turbines (256 MW) for the extension of the 90 MW Burbo Bank Offshore Wind Farm. The nacelles will be produced at the former Odense Steel Shipyard, while the blades are made at Vestas' Isle of Wight facilities. Assembly will take place in Belfast.[9][10][11]
