Benefits of Offshore Wind Power

…higher yield

…enormous potential

80% more capacity(wind turbines with a total output of 30 gigawatts

(GW) currently installed in Germany, further 25 gigawatts

offshore planned by 2030)

...sustainability7 months

until positive energy balance is reached (on average an offshore wind farm redeems the energy input for fabrication, transport and installation after this period)

100% CO2

-free power generation(even taking into account manufactoring, transport, installation and maintenance, CO2

emissions are only 7-12g CO2

/kWh)

…more steady yields100% more full-load hours

(offshore, with more than 4,000 operating hours annually at full load possible)

…high level of reliability

More than 2 decades of operation have already been sucessfully

completed by Siemens offshore wind power plants

97% availability

and better

higher expenditures,

Location

Case

Study: London Array


London Array – the

world´s

largest

offshore

wind power plant

Phase One:

175 Siemens wind turbines with a capacity of 3.6MW each, 120-meter rotor and a hub height of 87 meters above sea level.

Two offshore substations and an onshore substation.

Rated at 630 MW once operational

Could generate enough energy to power over 470,000 homes and displace over 900,000 tonnes of CO2

a year –

equivalent to taking nearly 300,000 cars off the road each year.

Siemens will also provide a warranty and five year turbine servicing contract.

Phase Two:

Expansion to a capacity of up to 1 GW

Developed by DONG Energy, E.ON and Masdar


London Array –

key

milestones

Project start date –

onshore construction at Cleve Hill started in July 2009

Offshore construction started in March 2011 when the first foundation was installed

First turbine erected –

end of January 2012

First power –

expected this autumn

All turbines of Phase One installed by end of 2012

End of August 2012: all monopiles

are installed

Increased rotor-swept area harvests more wind and is thus crucial for the annual energy yield of the turbine.

component cast in one piece.

No seams or glued joints and no adhesive, all of which saves weight.

3: 6 MW offshore gearless wind turbine

Direct Drive wind turbine with 6 MW rated power and a 120/154 m rotor diameter designed specifically for the harsh offshore environment

Simple and straightforward design based on and benefiting from experience with smaller Siemens Direct Drive turbines

Towerhead

mass less than 350 tons –

a new low-

weight standard for offshore turbines. This will contribute significantly to reduced cost of offshore wind energy, including Balance of Plant

Turbine design optimized for offshore installation and commissioning

High emphasis on safe and comfortable working environment, and cost effective service and maintenance Prototype installation Høvsøre, Denmark


By introducing line production for nacelles, the production time

was reduced by more than 50%, from 36 hours to 15 hours.

Another

way to lower

is

to produce

a larger of number
