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


19/26


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

Hywind


20/26


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.
