Siemens AG - Offshore Wind Power

Principles in Case study: 
Secure & affordable access to energy
Action taken by company: 

Siemens aims to develop offshore wind power so that it can be competitive with traditional, fossil energy sources as soon as possible. Only then will it be possible to substantially increase the share of sustainable energy in the world’s energy mix and achieve a shift towards low-carbon energy systems.


The two main levers to make wind power secure and affordable are innovation and industrialization.


From the perspective of Siemens Wind Power, innovation is all about making technology more efficient and less complex. The new Siemens direct-drive technology reduces the number of parts in the wind power turbine by 50% and decreases the weight by 30% compared with an equivalent geared machine. Thus, it offers increased performance as well as substantially lowering the cost of energy for offshore projects. Furthermore, Siemens’ new 6.0MW wind turbine features the largest rotor blades in the world. The blade is 75m and is based on revolutionary Quantum Blade® technology. The blades are cast in one piece in a closed process, making them lighter, stronger and more reliable.


The second lever for bringing down the cost of energy for offshore projects is to consequently industrialize the business. Implementation of platform strategy for the products as well as modularization and standardization will cut costs further.



Continuous innovation drives Siemens Wind Power and the achievement of providing access to affordable and secure energy. The unforgiving offshore environment demands reliability and robustness of its wind turbines. Since erecting the world’s first offshore wind farm in Vindeby, Denmark in 1991 costs have been reduced by 40% each decade. Constant learning is at the heart of this development and the learning-curve remains steep as costs are further reduced by optimizing the entire balance of plant.
