Vestas Denmark prototype turbine produces first kWh


Vestas has finalized installation of the V236-15.0 MW prototype turbine at the Østerild National test center for large wind turbines in Western Jutland, Denmark. The prototype has successfully produced its first kWh of power and will now undergo an extensive test and verification program to ensure reliability before full type certification and serial production begins.

“This is a great step forward in our ambition to accelerate the green energy transition and it is a major milestone for Vestas and our partners,” said Anders Nielsen, Vestas Chief Technology Officer. “Colleagues across Vestas have worked very hard and collaborated closely to ensure the rapid progress in developing and assembling the V236-15.0 MW prototype, and this achievement is a testament to the dedicated work of the many Vestas employees involved. With this wind turbine we set new standards for technological innovation, industrialization and scale across renewable energy to create a sustainable offshore wind industry.”

The prototype development and assembly work has taken place across Vestas’ R&D and production sites in Denmark. The blade molds have been developed at Vestas’ blade factory in Lem and the 115.5-meter prototype blades have been manufactured at Vestas’ offshore blade factory in Nakskov. The prototype nacelle has been developed and assembled at the offshore nacelle factory in Lindø port of Odense. The test program for the generator, converter, and grid system integration has already started at LORC test facility in Denmark.

With a swept area exceeding 43,000 square meters, the V236-15.0 MW moves the boundaries of wind-energy production to about 80 GWh/year, enough to power about 20,000 European households and displace more than 38,000 tons of CO2 every year.

The V236-15.0 MW is designed to perform while reducing the number of turbines at park level, strengthening the project business case. The globally applicable offshore turbine offers 65 percent higher annual energy production than the V174-9.5 MW, and for a 900 MW wind park it increases production by five percent with 34 fewer turbines. It offers partial-load production, resulting in a more stable energy production, and a capacity factor over 60 percent depending on site-specific conditions.

Launched in February 2021, Vestas has until now announced preferred supplier agreements for the V236-15.0 MW turbine for a total of more than 8 GW in five different markets.
