Power technology group ABB has landed a key order from Dutch-German transmission system operator TenneT to supply an alternating current (AC) transmission link connecting the Sandbank offshore wind farm in the German North Sea to the high-voltage direct current (HVDC) converter station SylWin alpha.
The 288MW connection will deploy two tri-core 155kV AC submarine cables, each 36 km long. The wind farm, being developed by Sweden's Vattenfall, will use 72 Siemens SWT-4-0-130
ABB will have turnkey responsibility for the design, engineering, supply and installation of the subsea cable system including two shunt reactors on the AC platform.
The project is scheduled for completion in 2015.
“Germany’s focus on renewable energy, the so-called ‘Energiewende’, together with the growing interest in using wind as an energy source in Europe provides significant opportunities for us,” states ABB chief executive Ulrich Spiesshofer.
“Integrating renewable wind energy efficiently and reliably helps deliver clean and affordable electricity to consumers in an environmentally sustainable way.”
Sandbank is the fifth offshore wind connection project in Germany awarded to ABB by TenneT. ABB is also supplying the Nordergründe AC cable link.
The other three projects are offshore wind connections based on HVDC Light technology.
BorWin1 has already been commissioned and DolWin1 and DolWin2 are under construction.
