DanTysk offshore wind power plant in the German North Sea was officially
inaugurated today. Siemens has supplied, installed and commissioned 80
wind turbines for the 288-megawatt project, each designed to generate 3.6
megawatts of power and equipped with a 120-meter rotor. Now Siemens wind
turbines with a total capacity of over 1 gigawatt feed offshore wind power
into Germany's power grid.
Owner and operator
of DanTysk wind park is a consortium comprising the Swedish power company
Vattenfall and Stadtwerke München, Munich's municipal utility. The
wind power plant can generate up to 1.3 billion kilowatt-hours of
electricity every year - equivalent to the total annual consumption of
about 400,000 German households.
"Including DanTysk
offshore wind power plant, the installed capacity of all Siemens wind
turbines in German waters now tops 1 gigawatt," says Michael Hannibal,
Offshore CEO of Siemens' Wind Power and Renewables Division. Around 300
wind turbines installed across eight projects contribute to this
milestone. Supplementary, Siemens has orders in hand for 700 additional
wind turbines to be erected off Germany's North Sea and Baltic Sea
coastlines which will add over 2.8 gigawatts of clean offshore wind
generated output to the existing capacity. This also marks a major
important milestone for the offshore power sector in Germany. The industry
association VDMA (German Engineering Association) expects up to two
gigawatts more offshore wind power will come on line in 2015. Experts in
Germany envisage in total about 3 gigawatts of installed capacity on the
grid by the end of 2015. As Hannibal adds, "Germany's energy transition is
thus also taking shape far out to sea."
DanTysk offshore wind power plant is located
approximately 70 kilometers offshore west of the German island of Sylt. In
waters measuring between 21 and 32 meters deep, foundations anchored in
the seabed provide the base on which the wind turbines were erected. The
wind turbines are not the only thing Siemens is providing DanTysk: the
German technology group is taking charge of preventive and corrective
maintenance to the wind turbines within the scope of a five-year service
agreement, and also supplied the turnkey grid connection for the wind
power plant, called SylWin1. This direct-current (DC) offshore link, run
by the transmission grid operator TenneT, comprises the connecting systems
that connect the offshore wind power plant to the German electricity grid.
SylWin1 consists of an offshore converter station at sea, and a receiver
station on land, 160 kilometers of undersea cable and further 45
kilometers of underground cable on shore. Overall, three offshore wind
power plants will be connected to the grid via this offshore link.
Hannibal continues: "We are not resting at our
oars after these successes. Siemens is working ceaselessly to lower the
costs of offshore wind power. We want to have technologies available
already by 2020 which, together with improvements to turbine foundations,
will make it possible to drive power generating costs from offshore wind
down below 10 euro-cents per kilowatt-hour." Just recently the company
introduced yet another advancement to its 6-megawatt series: This new wind
turbine, designed for 7-megawatt output, will be capable under high-seas
conditions of harnessing almost ten percent greater energy yield per year
than its predecessor model. Series production of these new units is
scheduled to begin in 2017.
Yet, Siemens is banking on innovating not only
its wind turbines, but also the vital grid connections: The high-voltage
alternating-current (AC) transformer platforms used to date mainly for
near-shore installations can in future be replaced by a significantly
smaller grid connection solution from Siemens based on alternating current
technology. The considerable savings of this innovative solution in terms
of both space and weight reduce costs substantially.
Siemens also offers cost-cutting solutions even
while wind turbines are in operation: New types of purpose-built ships
called Service Operation Vessels (SOV) form part of the logistics
infrastructure ensuring more efficient maintenance operations and thereby
significantly benefiting the availability of offshore wind turbines.
With renewable energy today accounting for 23
percent of power generation in Germany, it is the express aim of the
German Government to increase this share to 80 percent by 2050. Use of
offshore wind farms is an essential prerequisite to achieving this goal by
cost-efficient means. Strong winds at sea can be harvested and power
plants at sea are capable of drawing level with the electrical generating
capacity of fossil-fuel power plants. According to the Government's plans
wind turbines delivering a total installed capacity of 6.5 gigawatts (GW)
are to be installed in German waters by 2020, with 8.5 GW more to be added
by 2030.
