ABB, the leading power and automation technology group, has won an order
worth around $1 billion from the Dutch-German transmission grid operator
TenneT to supply a power link connecting offshore North Sea wind farms
to the German mainland grid.
This is the largest power transmission order in ABB's history. It will
deploy the world’s largest offshore HVDC (high-voltage direct current)
system with a rating of over 900 megawatts (MW), keeping electrical
losses to less than 1 percent per converter station. The completed link
will be capable of supplying more than 1.5 million households with clean
wind-generated electricity.
ABB will design, engineer, supply and install the offshore platform, the
offshore and onshore converter stations and the land and sea cable
systems. ABB's innovative and environmentally friendly HVDC Light
transmission technology will transport power from the 400 MW Gode Wind
II and other wind farms to an offshore HVDC converter station, which
will transmit the electricity to the onshore HVDC station at Dörpen on
the German coast via 135 kilometers of underwater and underground
cables. A converter station here will feed electricity into the mainland
grid.
"Offshore wind power is emerging as a major source of large-scale
renewable energy in Europe to help meet emission targets and lower
environmental impact,” said Peter Leupp, head of ABB’s Power Systems
division. ”ABB is uniquely positioned with in-house manufacturing
capability of converter stations, cables and semiconductors, the
essential components of HVDC systems, and has invested significantly in
these technologies."
ABB’s HVDC Light transmission technology offers environmental benefits
such as neutral electromagnetic fields and compact converter stations.
It is ideal for connecting remote offshore wind farms to mainland
networks and overcoming distance limitations and grid constraints, while
ensuring minimal electrical losses and efficient performance. The
320-kilovolt cable voltage capacity in this latest system is the highest
level used for HVDC transmission with extruded cables.
Scheduled to be operational in 2015, this offshore network will help to
avoid more than three million tons of carbon dioxide emissions per year
by replacing fossil-fuel based generation. Germany's installed wind
power capacity of over 27 gigawatts presently meets about eight percent
of its electricity requirements. Plans are to double that by 2020. This
is the third offshore wind connection order for ABB in Germany,
following the 800 MW Dolwin1 link awarded last year and previously the
BorWin1 project.
ABB provides a wide range of products, systems and services that enable
the efficient generation and integration of renewable wind energy into
the grid and its reliable transmission and distribution.
