Design life of the SWT-2.3-series
Calculated life of structure: 20 years
Total CO2-reduction: 60-120 kt
The energy consumption for making a SWT-2.3-series turbine is
generated within 3-6 months
Metal parts can be recycled or disposed
At present glass fiber parts are stored recycling possibilities in the near
future

Greater Gabbard Offshore Wind Farm
Onshore and
offshore wind farms
Burbo Offshore Wind Farm
Whitelee Onshore Wind Farm
Europe`s largest onshore wind farm. On Whitelee, Scotland, with an installed capacity
of 322 MW
Late summer 2008 - approximately half of the turbines installed
2007: the first offshore wind farm with 3.6 MW turbines installed in only one and a halfmonths
Total capacity of 90 MW located in the approach to Liverpool Bay
Burbo Wind farm can supply over 80,000 households
World's largest offshore wind farm ever contracted.
Located 25 kilometers off the east coast of Suffolk in Great Britain
140 wind turbines of type SWT-3.6-107 will provide about 504 MW in 2010
Green electricity can supply more than 415,000 homes

Innovations
Turbine Conditioning Monitoring
Flexible On-line System
Designed to continuously monitor the external and
internal state of the wind turbine.
Detects significant deviations from normal operating
condition when they occur.
Patented manufacturing process
Delivers an unique integrated blade with excellent
power and noise performance Based on vacuum-assisted resin injection without
adhesives or chemicals
Eliminates glue joints
State-of-the-art technology
Integral Blades

Direct Drive generator enables direct connectionbetween the rotor and the generator without a gearbox
Optimum production efficiency and reliability due toelimination of gearbox losses
Low generator losses as result of permanent magnet
Reduced maintenance costs
Cooperation on technology with Statoil Hydro todevelop World's first floating off-shore installation
Siemens will deliver (2009) the first wind turbine for thedemonstration unit, which will be positioned off thecoast of Norway
Floating offshore turbines could be installed at siteswith greater water depths
Reduced visual impact and increased power
production due to strong and stable wind conditions
Two exceptional innovations
Direct Drive

The blade - IntegralBlade
The blade is manufactured in a single
operation, using a closed process
invented by Siemens Wind Power
No glue joints between spars and shells,
no weak points, no easy access for water
or lightning
Combining superior strength with
excellent power and noise performance

Technology Evolution
Stall Technology: 600 kW and smaller Single Speed Shaft, Fixed Blade Design
CombiStall Technology: 1 MW to 2.3 MW Single Speed Shaft, Variable Pitch Limited, low-speed blade pitch adjustment to control output Limited ancillary service capability (frequency regulation, etc.)
Variable Speed/Pitch Technology: 2.3 MW and higher (current offering)
Full Converter Rapid Response
Variable Speed Shaft (but gearbox), Variable Pitch
Large Range of Possible Capabilities and Ancillary Services.
Prospective capabilities include Low Voltage Ride Through, RampRate Control, Frequency Regulation, etc.
Next Step? Possibly Direct Drive (eliminate gearbox) under review and
evaluation.
