Case
World’s tallest wooden wind turbine developed.
Sweden has a new wind power tower – made of wood! Knightec Group has assisted the wood technology company Modvion with their development of a unique wooden structure for wind turbine towers. These towers built using modules of laminated wood enables taller installations than conventional steel. Making it possible to extract more electricity while reducing CO2 emissions from material logistics.

Background
In the fall/winter of 2023, Modvion will inaugurate the world’s tallest wooden wind turbine tower outside Skara. The tower is 105 meters high and the company’s first commercial wind power tower. Once the turbine is mounted the total height of the plant will be 150 metres.
Modvion’s business concept utilizes the properties of wood and wood laminates in all possible situations. Here, the benefits are many. With modular wooden structures, it is possible to build taller towers than before, and thereby extract more electricity from each wind turbine. Additionally, logistics are simplified thanks to lighter materials and the fact that they are modular. CO2 emissions are also significantly reduced compared to steel and concrete towers.
Challenge
The challenge was to develop a new type of wind turbine tower that could replace traditional steel and concrete while maintaining strength, scalability, and reliability. At the same time, the solution needed to overcome limitations in transportation, cost, and height, enabling taller towers without increasing complexity or environmental impact.
Engineering a new generation of wind power.
Knightec Group supported Modvion in the development of a modular wooden tower concept, using engineered wood to create a lightweight yet strong structure. By applying product development and engineering expertise, the team helped design and realize a scalable solution that simplifies transportation and enables on-site assembly, making taller and more sustainable wind turbines feasible.
Delivered Value
The solution delivers value by combining increased energy production with lower environmental impact. The lightweight, modular design simplifies transportation and installation, while taller towers capture stronger winds and generate more electricity. Additionally, the use of wood reduces CO₂ emissions and stores carbon, making the solution both cost-efficient and sustainable over time.
