ABB to Create Transmission Link Between Offshore
Wind Farm and German Grid
Swiss automation and power engineering major ABB
will provide the technology to link what is claimed
to be the world's largest offshore wind farm to the
German power grid, in a contract valued at more than
ABB received the order from a unit of German utility
E.ON. The proposed link will use ABB's high voltage
direct current (HVDC) Light technology to transmit
large amounts of power underwater and underground,
with minimal impact to the environment.
ABB will build a rectifier station on an independent
platform 130km out in the North Sea. It will connect
the 80 wind turbines situated in the Borkum-2 offshore
wind power cluster to the German grid by transmitting
power to a receiving station on land using undersea
cables and landlines.
The wind farm is scheduled to enter service in 2009
with a combined output of 400MW. Many new wind energy
development plans have reportedly emerged since a
law was passed in December 2006 requiring German grid
companies to connect German wind farms as soon as
they are ready to be put into service, and to bear
the costs of the necessary connections.
This has reportedly reduced costs for wind power
developers by 25% to 30% and has significantly accelerated
the growth of wind farms. Current development plans
will see German offshore wind farms providing a total
of 12,000MW by the year 2020.
