The turbine produced its first kW of energy on 14 January, Vestas stated. It launched the low-wind V150-4.2MW alongside two other 4.2MW models in June 2017.
#Vestas has installed the first V150-4.2 MW™ in Østerild, Denmark ????. The V150-4.2 MW™ produced its first KW of energy on 14th January 2019, and is expected to offer a 21% increase in annual energy production*.

The turbine features 73.7-metre long blades and has a 166-metre tall, large diameter steel tower, for an expected tip height of 241 metres.
It is a direct evolution of the V112-3.0MW initially launched in 2010.
The V150-4.2 model has a rotor swept area of 17,671m2 and is capable of producing more than 17GWh per year, Vestas claimed.
Vestas had initially planned to have the first prototype installed by the end of 2018 ahead of serial production starting in the first half of 2019, Knud Winther Nielsen, the product manager of the 4MW platform, told Windpower Monthly at WindEurope’s 2017 conference in Amsterdam.
Vestas has since launched its new Enventus platform, which consists of two variants, both of which have higher power ratings than the V150-4.2, and one with a larger rotor.
The platform consists of the V150-5.6MW and the V162-5.6MW turbines.
