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

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.

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
the
cost
of energy
is
to produce
