With its 175 Siemens wind turbines and a total capacity of 630 megawatts(MW) the London Array offshore wind farm will, following completion, be the largest of its kind in the world. After Siemens Energy was appointed to supply the turbines for the wind farm, the company also received the order to connect London Array to the power supply network. Purchasers are Dong Energy, E.ON and Masdar, the wind farm's owners. The order volume isGBP 116 million EUR 128 million). The wind farm is scheduled to be completed by 2012 and will be connected to London's power supply network via the Siemens grid connection.

GBP116 million EUR128 million). The wind farm is scheduled to be
completed by 2012 and will be connected to London's power supply network
The wind farm is being erected in the Thames estuary off the Kent
and Essex coasts. An option is provided for uprating London Array
to as much as 1000 MW. The wind farm would become the first in the
1-gigawatt class.
That will be sufficient to supply 750,000 British households with
eco-friendly electricity, which is equivalent to approximately a quarter of
the population of Greater London. "Offshore wind farms of this size place
particular demands in terms of grid access. We not only have the requisite
technology and know-how but also a wealth of experience in connecting
offshore wind farms to the grid," said Udo Niehage, CEO of the Power
Transmission Division of Siemens Energy.
Siemens will supply the electrical equipment for two offshore
Substation platforms, which will be installed right at the wind farm.
The substations bundle the power generated by the 175 Siemens SWT-3.6
wind turbines, each rated at 3,6 MW, before it is transported via
high-voltage subsea cable to the coast. On each of the platforms there
are two 180-MVA transformers and medium-voltage switchgear. The
requisite protection and instrumentation and control equipment is also
installed on the platforms. Distribution over two platforms has the
advantage that the cable routes within the wind farm are short, and
power transmission losses are kept as low as possible to enhance
The wind farm's energy efficiency.
Siemens will also prepare the requisite design studies for grid
Access for all of the wind farm's electrical components and prepare the
grid studies to demonstrate fulfillment of grid access requirements.
The provision of energy-efficient grid access for
offshore wind farms is part of Siemens' Environmental Portfolio. In 2009,
revenue from the Portfolio totalled about EUR23 billion, making Siemens the
world's largest supplier of eco-friendly technologies. In the same period,
Our products and solutions enabled customers to reduce their CO2 emissions
By 210 million tons.
