V236-15.0 MW™ Prototype

Delivering on our promise

The V236-15.0 MW™ was the first ever 15 MW turbine to be introduced to the market in February 2021. We follow the journey as the prototype is developed this year.

The V236-15.0 MW™ prototype development work is progressing as planned across Vestas’ R&D and production sites in Denmark. With component production well underway and testing protocols in place, installation is on schedule for second half of 2022, with its first KWh planned for the fourth quarter of 2022. The on-track development of the V236-15.0 MW™ proves Vestas’ commitment to driving the offshore wind industry forward by offering customers a product which delivers excellent performance while reducing the number of turbines at park level. 

Østerild National test center

The V236-15.0 MW™ prototype will be installed at the Østerild National test center for large wind turbines in Western Jutland, Denmark. Stretching 280m into the air with a production output of 80 GWh/year, the prototype will be the tallest and most powerful wind turbine in the world once installed.

Testing and certification 

To accelerate the testing and verification process of the main protype’s components, Vestas has closely partnered with other testing facilities with specialist expertise. The prototype will then be installed onshore to facilitate easy access for final testing. With its modular construction incorporating common components used across existing offshore and onshore turbines, testing is less complex, using an iterative process that builds on experience from existing testing protocols. During the initial period of operations, Vestas will collect data needed to obtain a Type Certificate, a key step in reaching serial production of the turbine in 2024. 


At Vestas’ factory in Nakskov, Denmark, specialists are developing the blades for the V236-15.0 MW™ prototype using the mold which was built at the factory in Lem, Denmark. The factory in Nakskov currently employees around 460 experts in their field. Since the factory opened in 1999, producing blades for the V66 turbine, the facilities have constantly expanded to accommodate the increasing length of modern blades. In addition to the 80m blades of the V174-9.5 MW™, the production halls are now capable of handling the 115.5 meter blades of the V236-15.0 MW™ prototype.


Specialists from across the Vestas organisation are currently developing, testing and assembling the prototype nacelle at the offshore nacelle factory in Lindø, Denmark, where the serial production of V236-15.0 MW nacelles will also take place from 2024. The factory currently produces nacelles for V164-10 MW and V174-9.5 MW wind turbines and has delivered over 700 nacelles to the market leveraging the expertise and experience developed over the past ten years. Before V236-15.0 MW serial production commences, Vestas will modify and expand the Lindø facility to accommodate the larger components.
