The Vestas V164 is a three-bladed offshore wind turbine, produced by Vestas, with a nameplate capacity of up to 9.5 megawatt, a world record. Vestas revealed the V164's design in 2011 with the first prototype unit operated at Østerild in northern Denmark in January 2014. The first industrial units were installed in 2016 at Burbo Bank, off the west coast of the United Kingdom.
Since 2014 this offshore turbine has had the largest power generation capacity, with diameter of rotor 164 metres (538 ft) and swept area 21,124 square metres (227,380 sq ft). Each blade weighs 33-35 tonnes.
Originally called the Vestas V164-7.0MW, at 7.0 MW, the output was increased to 8.0 MW, later to 9.0 MW. In 2017 the turbine capacity was upgraded to 9.5 MW. The next largest wind turbines and competitors to the V164 are the Siemens Wind Power SWT-8.0-154 and Adwen AD 8-180 offshore turbines with a rated capacity of 8 MW. The Enercon E-126 turbine is rated up to 7.58 MW, but only installed onshore.
Starting November 2013, a prototype was installed at Østerild test station. The bottom tower sections weighs over 200 tonnes and is 24 meters long and 7 meters 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 m (720 ft). It became operational in January 2014. Later that year favourable winds allowed it to sustain its rated 8 MW power for 24 hours for a record one-day production of 192 MWh. In 2017 the 9 MW version did the same for a new one-day production record of 216 MWh.
United Kingdom: Burbo Bank Offshore Wind Farm
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 were produced at the former Odense Steel Shipyard, while the blades are made at Vestas' Isle of Wight facilities. Assembly took place in Belfast. Installation began in 2016 and the wind farm was commissioned in April 2017.
Belgium: Norther N.V. Wind Farm
In December 2016, Norther N.V. (Eneco/ Elicio) announced that MHI Vestas Offshore Wind will provide 44 x V164-8.4 MW (totalling approximately 370 MW) wind turbines to Belgium’s largest offshore wind project, located in the Belgian North Sea, approximately 23 km off the coast of Zeebrugge.
Belgium: Northwester 2 Wind Farm
In April 2018, Parkwind and MHI Vestas announced that MHI Vestas Offshore Wind will provide 23 x V164-9.5 MW wind turbines. Both companies attribute the fast installation timetable, set for late 2019, to the industrialisation of offshore wind in Belgium.
Denmark: Esbjerg, Måde
In April 2016, two turbines were inaugurated in Måde, each providing 8 MW power for a total of 16 MW. These turbines are series 0, i.e. a pre-mass-production model that may allow for further improvements in the design.
Denmark: Horns Rev 3
In 2014, Danish Energy Agency announced that MHI Vestas Offshore Wind will provide 49 x V164-8.3 MW (totalling 406.7 MW) wind turbines to the farm Horns Rev 3, located in the Danish North Sea, approximately 40 km from Esbjerg.
