Vestas 15 MW prototype WTG produces first kWh

10 January 2023

Vestas has finalised installation of its V236-15.0 MW offshore WTG prototype at the Østerild National test centre for large wind turbines in Western Jutland, Denmark. On 30 December the prototype produced its first kWh of power and will now undergo an extensive test and verification programme to ensure reliability before full type certification and serial production begins.

“This is a great step forward … colleagues across Vestas have worked very hard and collaborated closely to ensure rapid progress in developing and assembling the V236-15.0 MW prototype … with this wind turbine we set new standards for technological innovation, industrialisation and scale across renewable energy to create a sustainable offshore wind industry”, commented Anders Nielsen, Vestas Chief Technology Officer.

The prototype development and assembly work has taken place across Vestas’ R&D and production sites in Denmark. The test programme for the generator, converter and grid system integration has already started at LORC test facility in Denmark.

With a swept area exceeding 43 000 sq m the V236-15.0 MW is expected to moves the boundary of wind energy production to around 80 GWh/year, enough to displace more than 38 000 tonnes of CO2 every year.

The V236-15.0 MW is globally applicable and offers 65 % higher annual energy production than the V174-9.5 MW. For a 900 MW wind park it would increase production by 5% with 34 fewer turbines. It is said to offer excellent partial-load production, and a capacity factor over 60 % depending on site-specific conditions.

• Vestas has received a 252 MW order to power an undisclosed wind project in Australia, consisting of 42 V162-6.2 MW WTGs in 6.0 MW operating mode. Vestas will also deliver the engineering, procurement and construction (EPC) of the turbines, as well as a 30-year AOM 5000 service agreement, designed to optimise the performance of the assets.

Delivery of the wind turbines is expected for the first quarter of 2024, with commissioning planned for the fourth quarter.
