Alternating current electricity generated in three wind farms off the coast of Germany will be converted on the platform into high-voltage direct current (HVDC) for transmission to the mainland.
The 320 kilovolts converter station has an 800 megawatt power transmission capacity making it the world's most powerful installation of its kind.
ABB was contracted for system engineering, design, supply and installation of the offshore wind connection by TenneT, a European transmission system operator. The project scope includes the offshore converter station, the sea and land cable systems, and the onshore converter station.
The DolWin 1 offshore wind connection is expected to avoid 3 million tonnes of carbon dioxide emissions per year by replacing fossil-fuel based generation.
