REACH MEGA HEIGHTS
Wind turbine towers are set to reach heights of up to 170m with new construction techniques and materials, according to wind power engineering specialists K2 Management. Tower heights have grown steadily over the last decade as operators seek stronger wind speeds higher up in the atmosphere.
NEW TECHNOLOGY DEVELOPMENTS Based on work with various clients across the globe, K2 Management believes new technology developments like modular concrete structures mean turbine heights are likely to soar to up to 170m in the coming years – higher than London’s ‘Gherkin’, and almost as high as the Eiffel Tower.
This compares to the tallest towers of 150m at present. There has been a 48% increase in average hub height since 1999, and based on its experience in the industry and its partnerships, K2 Management has insight on how to manufacture hybrid tower concepts up to 170m.
COMPARISONS
According to K2 Management wind resource experts, a 3 MW turbine located in a forest area for example, with an average wind speed of 6 metres per second, will meet 13 percent more wind speed if the turbine height doubled from 70 to 140 metres. Annual energy yield prediction would increase by almost 30 percent because of less surface aerodynamic drag and the viscosity of the air. Therefore, going up to 170 metres from 70 metres will boost energy yield prediction by 35 percent on average. The more complex the terrain – for instance forests, hills, mountain, buildings – the larger the impact is in using taller turbine towers.
COMMON SIGHT
K2 Management CEO Henrik Stamer says: “170m towers could become a common sight in the near future in markets like the USA and Germany as part of a new renewable skyline. We expect to see more of these mega designs as we help our clients get the most out of their wind projects.”
UNIQUE VANTAGE POINT
Through its network of experts across the globe, K2 Management possesses a unique vantage point overlooking the wind industry, allowing for a view into emerging trends.
The company is able to draw on this wide breadth of experience to identify ways of making wind projects more efficient.
Stamer adds: “As a company that is at the global cutting edge of technology we are helping push the limits of the wind industry in terms of power generation efficiency, cost-effectiveness and return on investment; and these new mega wind turbine towers are a case in point.”
