4. Wind Technology development
Key industry-wide factors since 2000
New Grid Requirements significantly increased for flexibility
Variable Speed Dominance with different converter systems
Aerodynamic Improvements and Rotor Loading has been decreasing; shift
towards lower mean wind speeds
Offshore Wind power best practices for infrastructure and installation solutions
Overall Trends:
- Turbine sizes will continue to grow, but much slower than before
- Reliability will be even higher priority than now
- Focus on weight reductions will increase
- New manufacturing and transportation concepts will be developed
Power conversion: Generator excitation will be with permanent magnets
Machinery and support structure: Hybrid structures will become common
Grid interaction:
- Wind turbines have to be ”power plants”, not just ”energy plants”

9. Siemens Service is a global organization
with local set up
Siemens has a global service organization to
ensure highly qualified personnel are deployed
on time
Think Regional Organization Follows global processes
Global and tools
Ensures high quality and safety standards along
the lifecycle of wind turbines and wind power
plants
Manages Service Region as regional
entrepreneur
Resources, skills and experience are
Act transferred locally, optimizing response time
Local and interaction
Provides feedback to HQ with local knowledge
and experience; drives improvement ideas
Maximizes the customer value from the power
plants through service excellence,
responsiveness and customer intimacy

11. Conclusion
Quality leadership based on a solid design with
innovative but robust solutions
97 % of the 1983-1990 turbines are still in operation,
18 to 25 years after installation.
Wind Farm availability with professional
maintenance support services, your network could
reach up to 95% or more
Engineering locally providing fast feedback loop &
fault analysis to fix problems & ensure high reliability
Qualified and experienced local resources at local
sites are key for success
Efficient Supply Chain ensuring short lead- &
delivery time for spare parts
Professional training covering major and critical
areas, including HSE, of wind turbines is supporting
the operation of the network .
Our Regional services networks are the key to
maintain the high availability of Siemens Turbines
Availability: number of hours the turbine is operating or is ready to operate divided with the total number of hours in the year. Grid outage, excess wind
speeds and other factors outside Siemens’ influence do not count against availability
